Measuring Your Roof with Google Earth: A Step-by-Step Guide

How to Accurately Estimate Roof Size for Roofing Projects


Measuring your roof’s square photos is vital for obtaining specific Roofing fees and ensuring you purchase the appropriate materials. Here’s a step-by-step guide to measuring your roof and using Google Earth and other gear.


Roofing Quote Footage vs. Home Square Footage


Roofing Quote Footage: This is the entire region that needs to be included with Roofing substances, all roof surfaces, and capabilities like dormers or skylights.


Home Square Footage : refers to the total living area inside your home, not the Roofing area.


Measuring the Roof’s Pitch

The pitch or slope of your roof affects the amount of fabric you wish to use. 

Here’s a way to measure it:

Tools Required: Level, tape degree, pencil.


Method:

  • Position the Level: Place the extent horizontally on a roof rafter.

  • Mark 12 Inches: On the extent, mark off 12 inches.

  • Measure Vertically: Measure vertically from the 12-inch mark on the level up to the bottom of the rafter. This vertical dimension is the rise.

  • Calculate Pitch: The rise over the run (12 inches) expresses the roof pitch. For instance, a four-inch upward thrust over 12 inches is a 4/12 pitch.





Considerations for Different Roof Pitches

Roofs regularly have various pitches, particularly around features like porches or dormer windows.

  • Measure and notice each specific pitch to ensure accurate surface location calculations.

  • Using Google Earth for Roof Measurement


Google Earth can help estimate roof regions. 

Here’s how:

Steps:

  • Open Google Earth: Navigate to your own home.

  • Zoom In: Get a clear view of your roof.

  • Outline the Roof: Use the polygon tool to define the roof’s perimeter at factors in which the elevation is regular.

  • Avoid Peaks: Do now not outline along the peak of the roof, as angled satellite snapshots can distort measurements.


Precautions:

  • Image Angle: Aerial Roof Measurements may be angled, introducing errors. Aim for overhead perspectives when possible.

  • Complex Roofs: For roofs with multiple degrees or capabilities, degree each phase one by one.


Limitations of Google Earth

  • Accuracy: Google Earth provides a reasonable rough estimate but is not 100% accurate. Use it as a starting point, not the sole method for critical decisions.


  • Verification: Always verify measurements with manual techniques or expert equipment for unique estimates.


Final Steps

  • Combine Measurements: Integrate all the exceptional sections measured, accounting for pitch versions.


  • Calculate Total Area: Convert all measurements into rectangular pictures. Remember to add more for waste and overlap, generally around 10%.

How do you measure a roof for satellites?

What are Satellite Roof Measurements?

Satellite Roof Measurement are measurements taken from an aerial view of your home. The measurements are then calculated with software. You can actually do this on google maps with the aerial view of the house. There is even a measuring tool that can tell you how many feet by how many feet the roof is.

If the house is not actually square then you have to add each section together. Many roofers add 10 % of the whole measurement to make sure they have enough materials. This helps if you are going to the home improvement store and have to know how many shingles you need.

Knowing the measurement helps you know how much of the other materials you need as well. Most materials for roofs are broken down by square footage. This way you will not end up buying too little or way too much. It always good to buy a little extra.

How do you calculate the fall on a flat roof?

How to Calculate Roof Pitch in Degrees
  1. First, you need to measure the run of your roof. …
  2. Next, you need to figure out the rise. …
  3. Now, divide the rise by the run. …
  4. Then, divide 1 by your tangent.
  5. Finally, multiply this result by 180/π and you’ve calculated your roof pitch!
A flat roof is generally any roof with a pitch of 1-10 degrees. That means flat roofs aren’t actually flat. It may look horizontal but often has a minimum slope of 1/4 inch per foot. This allows water to run off the roof to prevent damage.
Generally, roof pitch is calculated from the same formula that describes a right triangle. You can use the following equations to find the length of the rafter and the slope: rafter² = rise² + run² (from the Pythagorean theorem); rise / run = pitch , where pitch is expressed in percent; and.
 
To calculate percent slope, divide the difference between the elevations of two points by the distance between them, then multiply the quotient by 100. The difference in elevation between points is called the rise. The distance between the points is called the run. Thus, percent slope equals (rise / run) x 100.
Pick two points on the line and determine their coordinates. Determine the difference in y-coordinates of these two points (rise). Determine the difference in x-coordinates for these two points (run). Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).

How to measure a roof and calculate square feet.

How do I Measure a flat roof?

Just measure the length and width of each plane on the roof, including dormers. Then, multiply length x width to get the square footage of each plane. Simply add the square footage of each of the planes together to derive the total square footage of your roof.

How to calculate a flat roof area in square metres. Measure the length and width of the structure from the outside for accuracy. Multiply the two figures to calculate the square meterage of the flat roof. E.G. 4 metres (length) multiplied by 3 metres (width) = 12 square metres in total.
Two feet is the general maximum length for a typical roof overhang. This will protect a roof from most types of damage. Roof overhangs can extend farther than 2 feet, but beyond this length, they begin to lose structural integrity and require external support.
A flat roof is generally any roof with a pitch of 1-10 degrees. That means flat roofs aren’t actually flat. It may look horizontal but often has a minimum slope of 1/4 inch per foot. This allows water to run off the roof to prevent damage.
Roof cost by material type. The average cost for a new asphalt roof in 2021 was about $28,256. Inflation was up 8.5% on average for the last 12 months (ending in March 2022). With this in mind, you can estimate that the average price for an asphalt roof will be about $30,700 in 2022.
Asphalt shingles are most often allowed in up to two layers, but no more. For flat roofs, materials such as EPDM and TPO are usually approved for use up to two layers.
The smallest pitch of a roof is 1/4:12, which translates to 1/4 inch rise to 12 inches of run. Such a small pitch can only work with built-up roofing or specialized synthetic roofing. Covered porches that are near trees or in areas with heavy rains should not be covered with a low-slope roof.
If your roof was properly installed, your attic is adequately ventilated, and your roof is maintained, it will get as close as possible to the maximum lifespan. This means you shouldn’t need a replacement for around 20 years or even up to around 50 years (or longer), depending on what kind of roofing material you have.

How To Measure a Flat Roof?

Just measure the length and width of each plane on the roof, including dormers. Then, multiply length x width to get the square footage of each plane. Simply add the square footage of each of the planes together to derive the total square footage of your roof.

What is the easiest way to measure a roof?

Multiply the area by the pitch multiplier to get the roof’s square footage. First, multiply the length by the width. Then, take the product of these two dimensions and multiply it by your pitch multiplier. The number you get will be an accurate estimate of how much area you have to cover for your roofing project.

How do you find the slope on a flat roof?

For drainage purposes, the current building codes require a minimum two percent slope or a one-fourth unit vertical for every 12 units horizontal. In other words, the roof must slope one-fourth of an inch for every 12 inches. The slope is barely noticeable to the naked eye.

Roof Measuring

If your roof is too steep to navigate safely, you can use one of two alternatives. If you have an attic that you can easily access, measure the roof from the inside of the attic. Otherwise, measure the length of the roof by measuring the length of the wall that it hangs over and add a foot for overhang. Using a ladder, stand at the edge of the roof and measure the width by feeding a stiff measuring tape from edge to the peak of the roof. Repeat this for all sections of the roof, and then multiply the length and width of each section to get total square footage.

There are 12 roofing squares in 1200 square feet. The surface of roofs is basically measured in squares. One square is equal to 100 square feet of the roof. To calculate the number of squares of the roof, divide the total square feet by 100.
Around 1,700 square feet The typical residential roof size in the United States is roughly 1,700 square feet, or 17 squares, while many bigger homes have roofs that are well over 2,000 square feet, or 20 squares. Larger residential homes with garages can often reach 3,000 square feet, or 30 squares.

Comparisons are made at sites in various states including rural and urban locations. The comparisons show that Google Earth images yield reasonably accurate measurements (RMSE 0.569 feet) over the scale of typical accident reconstruction distances.
First, measure the length and width of each surface on the roof, then multiply these values to get the square footage of that surface. Make sure to document the number of chimneys, skylights or other obstructions and include dormers in your measurements.
There are 12 roofing squares in 1200 square feet. The surface of roofs is basically measured in squares. One square is equal to 100 square feet of the roof. To calculate the number of squares of the roof, divide the total square feet by 100.
For a 1500 square foot house, you will need approximately 19 squares or 57 bundles or 1653 pieces of 3-tab standard-sized shingles (12 inch by 36 inch) when overhangs is 1 feet and roof slope is 4/12.
Once you’ve determined the square footage you need to cover, you can figure out the number of bundles you need by dividing the total square footage by 33. Example: if you have 2,000 square feet of roof to cover, that means you’d need about 60 bundles (2,000 divided by 33 is about 60).
The average cost for a square of roof shingles, which is 100 square feet, ranges from $170 to $400, depending on materials used. On the low end, asphalt shingles cost an average of about $150 per square, while high-end slate shingles average around $1,200 per square.

For a 1800 square foot house, you will need approximately 23 squares or 69 bundles or 2000 pieces of 3-tab standard-sized shingles (12 inch by 36 inch) when overhangs is 1 feet and roof slope is 4/12.
 
A roofing square is equal to 100 feet on your roof. If your roof measures at 1800 square feet, you would need 18 squares of shingles to cover your roof.
With that said, on average, most roofing companies will charge somewhere between $3.50 and $5.50 per square foot, or $350 to $550 per square (100 square feet) to install or replace an asphalt shingle roof.
 
Multiply the product by the flat roof area and divide by 100:- our 12×16 shed square footage with overhangs is 252 sq ft, so 1.118 x 252 = 282 square feet, 282 / 100 = 2.82 squares. Round this number up and thats your answer, 3 squares!

How to Manually Measure a Roof

To manually measure a roof without the help of aerial measurement reports, you must visit a job site and climb onto the roof to take precise roofing measurements by hand. Here are the 6 steps to get a manual roofing measurement.

 
  1. Measure the width and length of each plane of the roof (including dormers), and then multiply those numbers to get the correct figure for the square footage of that area.
    Example: Plane 1 (A x B): 50’ x 20’ = 1000 sq ft
    Plane 2 (A x C): 50’ x 20’ = 1000 sq ft
  2. Note any skylights, chimneys or other parts of the roof that would not require materials. You can subtract those measurements from your total area.
  3. Add together the calculated square footage of each surface to get the figure for total square footage of the roof.
    Example: Plane 1 (1000 sq ft) + Plane 2 (1000 sq ft) = 2000 sq ft
Diagram of roof planes to calculate square footage.
  1. After determining the total square footage of the roof, you must calculate the pitch of the roof. Measure the vertical distance (rise) over a 12 inch horizontal segment (run).
    Example: The rise of this roof is 5”.
  2. Write down these numbers as the vertical measurement listed first and the horizontal measurement recorded second so you can find rise over run.
    Example: The rise over run of this roof is 5” over 12”.
  3. When you have the total square footage and rise over run of the roof, you can calculate the roof squares to determine how much materials are needed to cover the roof. To calculate the number of squares on a roof, you need to divide its total square feet by 100.
    Example: 1000 sq ft / 100 = 10 squares

With those roofing measurement figures, you can then estimate the roofing supplies needed for a job.

Our  Roof Measurement Technologies produces roof charts wherein we take most extreme consideration of the multitude of subtleties like deterrents on roofs, accurate pitch estimation by seeing various appearances on Aerial Photos (East, West, North, and South) additionally lengths of the Eaves, hips, valleys, rakes, overhang, the space of every aspect and absolute space of the roof. Additionally, significance is given while appointing line ID as this is pivotal in planning roof outlines.

Roof replacement cost for different roofing materials

Roofing materialAverage cost per square footAverage total replacement cost*
Asphalt shingles$3.40 – $5.95$5,840 – $10,100
Metal roofing$6.00 – $24.50$10,245 – $41,640
Tile roofing$6.30 – $12.30$10,665 – $20,900
Wooden shakes / shingles$6.00 – $9.15$10,230 – $15,500

The average cost to replace a roof can vary quite a bit. The typical range for roof replacement costs is between $5,100 and $10,000, but roof replacement can be as low as $1,200 or as high as $30,000. Many roofing companies will charge between $3.50 and $5.00 per square foot.

This results in a wide range of costs associated with replacing your roof . The state average cost to replace a roof is $6,000 to $20,000, with most homeowners paying around $12,000 for a 2,000 sq. ft. roof replacement using hail-resistant architectural shingles.

Tile and Asphalt are the most used materials for roofing, and they’re manufactured with the usage of concrete, clay or oil. The rise of oil prices can directly impacted asphalt shingles to become more costly. Furthermore, the cost of disposing old and damaged materials has also increased in the recent years.
In 2022, roofing material prices increased by about 6%-8%, and may continue to rise by 10%-12% within the next year. This includes the prices for shingles, underlayment, decking, and other essential materials for a high-quality roof.
That’s for good reason. Asphalt is the cheapest of all roofing materials in the market and will last you between 15 to 30 years. This is the best option for homeowners facing budgetary constraints. It is also widely available and comes in a variety of colors.
Roofing material that lasts the longest are concrete, clay or slate tiles. These materials significantly outperform other natural products like wood shakes or any manufactured roofing materials including asphalt shingles and metal roofing. Although these materials have a good lifespan, they are not as durable.
Metal roofing is by far one of the best choices you can make for your roof in general. They’re the most energy-efficient roof for residential installations, can last more than 50 years, and require very little maintenance. Metal roofs are very reflective, which is why they get so hot to the touch.

How Much Does It Cost to Replace a Roof on a 2000 Square Foot house in Florida?

In Florida, the estimated replacement of the roof is around $7000-$7200. Homeowners could expect more since the costing may vary depending on the choice of contractor, as there are factors to consider.

In general, this is the recommended replacement schedule based on the material used: Composition Shingles: 12-20 years. Asphalt Shingles: 15-30 years. Wood Shingles: 20-25 years.
Roof Calculations of Slope, Rise, Run, Area
To answer the question concisely: Yes, insurance will cover a 15-year-old roof in many cases. Insurance companies won’t just pay to replace a roof because it’s old, but if your old roof has significant damage caused by insurable events then it’s highly probable that they’ll pay for roof repairs or a roof replacement.
Asphalt Roofing Shingles

Relatively lightweight, inexpensive, and easy to install, asphalt shingles are the best choice for most houses. They come in sheets that are layered on a roof to give the illusion of more expensive single shingles, such as cedar and slate, that are installed one shingle at a time.
If your roof has sprouted a moss infection, you can remove it before it becomes serious enough to impact the performance of your roof. Moss is tough and typically you will not be able to remove it by hand. However, you can use a chemical solution to loosen the moss without damaging the shingles.

What Roofing Material Lasts the Longest?

  • Wood shakes and shingles: 15 to 20 years.
  • Asphalt shingles: 10 to 30 years.
  • Metal/steel: 50+ years.
  • Slate: 50+ years.
  • Tile and concrete: 50+ years.
  • Foam: 25+ years.
  • Built-Up roofs: 25-30 years.
  • Single-Ply: 30+ years.

How many squares does it take to roof a 2000 square foot home?

How many shingles do I need to protect my roof?

The surface area of your roof will affect the number of bundles or squares you need. A 2,000 square foot roof requires 20 squares or 60 bundles.

A roofing square is equal to 100 square feet of the roof. To determine the number of squares on the gable roof example in this post, divide its total of 2400 square feet by 100 (2400 ÷ 100 = 24). This means you would need 24 squares of shingles to cover that roof.
One square is equal to 100 square feet. Examples where the unit is used are roofing shingles, metal roofing, vinyl siding, and fibercement siding products. Some home builders use squares as a unit in floor plans to customers.
A square of shingles is the quantity needed to cover 100 sq. ft. of roof. Shingles are packaged in paper- or plastic-wrapped bundles designed to be light enough for a person to carry, so heavier shingles require more bundles per square.

Asphalt three-tab shingles cost around $1 to $2 per square foot.

Price of Roofing Shingles Per Square Foot.
Roof AreaCost of Shingles
750 square feet$700 – $800
1,000 square feet$910 – $1,100
1,500 square feet$1,400 – $1,600
The size of a three-bedroom home can vary depending on the size of additional rooms, with an average of 1,200-1,300 square feet. This is equivalent to 110-120 square metres.
There are 12 roofing squares in 1200 square feet. The surface of roofs is basically measured in squares. One square is equal to 100 square feet of the roof. To calculate the number of squares of the roof, divide the total square feet by 100.
With that said, on average, most roofing companies will charge somewhere between $3.50 and $5.50 per square foot, or $350 to $550 per square (100 square feet) to install or replace an asphalt shingle roof.
 
By saying this, you might already realize that the difference between a 30-year shingle and a 50-year one is how long the product is guaranteed to last. In other words, 30-year architectural shingles are covered by the manufacturer from any unforeseen defects that could occur once the shingles are installed.

How many shingles do i need for a 12×12 shed:- for a 12×12 shed roof, you will need approximately 3 squares or 9 bundles or 261 pieces of three tab strip standard-sized shingles (12 inch by 36 inch) when overhangs is 1 feet and roof slope is 6/12.
How many bundles of shingles do i need for 1200 square feet:- for 1200 square feet or 12 squares roof, you will need approximately 36 bundles of standard size 3-tab shingles (12×3 = 36 bundles). Thus, for a 1200 square foot gable roof, you would need 36 bundles of shingles plus 10% of ridge, starter and wastages.

Prices are based on a cost of around $30 to $35 per bundle of asphalt three-tab shingles or about $90 to $100 per square

By saying this, you might already realize that the difference between a 30-year shingle and a 50-year one is how long the product is guaranteed to last. In other words, 30-year architectural shingles are covered by the manufacturer from any unforeseen defects that could occur once the shingles are installed.

Roof Area Calculation

How to Calculate Roof Areas?

Multiply your house length by your house width to get the area. (For example, 40 feet x 30 feet = 1,200 square feet.) Next, multiply the area by your roof’s pitch. (1,200 x 1.05 = 1,260 square feet.)

Finding the Size of the Roof in Squares


A square simply refers to a 10′ x 10′ square of roofing. This is simply 100 square feet of roof. To find the squares, divide the overall roof area by 100 and then round up. For instance, if the roof is 1550 square feet, then it is 16 squares.

Since there are twenty six shingles in a bundle of twenty year shingles (which is fine for starters and edges), divide the result by twenty six. For the number of ridge caps, multiply the length of the hip or ridge by twelve and divide it by five. This house is 1000 square feet. It requires 18 squares of shingles.

How many squares is 900 square feet?

To do this, measure the length and width of each plane on the roof, including dormers. Then, multiply length x width to get the square footage of each plane. Finally, calculate your roof’s total square footage by simply adding the square footage of each of the planes together.
For example, if you want to figure out the actual length of a common rafter with a plan length of 10′ for a “10 in 12” roof you would simply multiply the plant length by the “10 in 12” factor for common rafters. Therefore, the actual length would be 10′ x 1.302 = 13.02′.

Roof Calculations of Slope, Rise, Run, Area

How Do You Calculate Rafter Length

How to calculate rafter length?

The formulas we use are the following:

  1. For calculations based on the roof rise:

rise² + run² = rafter length² ,

meaning that:  rafter length = √(rise² + run²).

aerial roof measurement
Pitch – Is the incline of the roof represented as the ratio of rise to the span (twice the run). For example, if the roof rises 4 feet and the span is 16 feet (twice the run), then the pitch is 4/16, or 1/4.
But they do tend to space rafters in one of several industry-standard increments, typically either 12, 16 or 24 inches apart. These spacing intervals are measured “on center,” meaning that the measurement is taken from the center of one rafter’s horizontal surface to the center of the next rafter.
Maximum allowable span for a 2×6 rafter:- the maximum allowable span for 2×6 rafter is 16 feet 5 inches when spaced 12 inches apart from centre, 14 feet 8 inches at 16″ OC & 12 feet 8 inches at 24″ OC with best quality No.

Estimate Roof Size
The length of the rafter is given from the long point of the ridge cut at the top down along the top edge the board to the same plumb cut on the rafter’s notch. The next result is the run. This is the horizontal measurement from the outside of the wall to the inside of the ridge.
Rafter span: this is the distance between the supporting wall and the centre of the roof measured horizontally. The span is NOT the distance between the supporting wall and the peak of the roof measured along the diagonal. Rafter: This is the lumber that runs from the centre (peak) to the supporting wall.
2-grade 2×6 joists can span up to 10 feet 9 inches from beam to beam when spaced the standard 16 inches apart with a maximum live load of 30 inches per square foot. In comparison, No. -1 grade lumber can span slightly further to 10 feet 11 inches under the same parameters.
 
In general, a 2×8 will span 1.5 x 8, so 12-feet. Based on all factors though, a 2×8 joist span is 7′-1” to 16′-6”, and a rafter 6′-7” and 23′-9”. In this guide, we’ll explain what span means in terms of construction, factors that impact the span, and how much weight a 2×8 can support.

How To Calculate Roofing Square feet

A roofing square is a 10×10 area that’s equal to 100 square feet of roof surface.
A square simply refers to a 10′ x 10′ square of roofing. This is simply 100 square feet of roof. To find the squares, divide the overall roof area by 100 and then round up. For instance, if the roof is 1550 square feet, then it is 16 squares.
So a roof that has 1600 square feet of area has 16 squares. Remember that unless the roof is flat, the square footage of the building is different than the square footage of the roof.

How to measure your roof’s square footage 

The square footage of your roof has a huge impact on the cost of your replacement. It affects a number of cost factors, including the amount of materials used, labor, and time. 

Be aware, the only way to get a 100 percent accurate measurement is to have a local roofing contractor come out to professionally measure your roof and give you a quoteHowever, I can give you the calculations to get a rough measurement of your home’s square footage.

Area of a rectangle or square:
A = L x W
Area = Length x Width
Example: 20 feet x 10 feet = 200 square feet

Area of a trapezoid:
A = [(B1 + B2) x H] / 2
Area = [(Top + Bottom) x Height] / 2
Example: [(5 feet + 10 feet) x 6 feet] / 2 = 45 square feet

Area of a triangle:
A = (B x H) / 2
Area = (Base x Height) / 2
Example: (5 feet x 4 feet) / 2 = 10 square feet

When you have finished calculating the area of each plane, use this information to find your roof’s total square footage. Add the area of each plane together, and the sum will be the total square footage of the roof.

The Drip Cap

  • Before you do any roofing work, you must calculate the roof’s square footage to determine how much material you need.
  • Calculate each plane separately.
  • For example, if a triangle-shaped roof plane measures 60 feet along the base and is 30 feet high, we have 60 x 30 = 1,800 feet, divided by 2 = 900 square feet for the triangle-shaped plane.
  • The square footage would be 40 x 40 = 1,600 square feet (the square) plus 20 x 40 = 800 / 2 = 400 square feet (the triangle).

Roof Measurements

What is the standard unit for roofing measurement?

A roofing square is a unit of measurement for calculating the size of a roof and is equivalent to 100 square feet. The larger unit is useful for calculating the amount of material needed for a roof. It’s common to calculate the size of your roof in “squares”, and then order an additional 15% in backup materials.

How do you calculate the rise and run of a roof?

Calculate the roof rise using the figures for unit rise and total run. Multiply your figure for unit rise by your figure for total run to get the total rise. Using the example, it would be six inches times 13 feet. The total roof rise in the example equals 78 inches.

How do I calculate a rise?

Subtract the difference in elevation between two points on a hill to calculate the rise. The elevation could be determined by an altimeter or you could use a topographic map. As an example, you might read 900 feet at the top of a hill and 500 feet at the bottom, so subtract 500 from 900 to get a rise of 400 feet.
 

What are the 4 types of slopes?

Slopes come in 4 different types: negative, positive, zero, and undefined. as x increases. The slope of a line can also be interpreted as the “average rate of change”.

How to measure your roof area from the ground

A more accurate way to calculate the area of the roof than using Google Earth is to get outside to estimate the roof pitch and the base area of the property. Using these two figures, we can get a good idea of the shingle roof’s square footage and estimate your asphalt shingles’ needs and costs. This DIY technique can be helpful, especially if you are not comfortable getting on your roof, or if you have limited access to it.

Ground measures only work well for a gabled roof, since there are usually just two main rectangular pitches to calculate area for. For more complex roof shapes, like hip roofs, you’ll need to work with a roofer or measure from on top of the roof itself to calculate its total area.

Tips for Estimating Roof Shingles

The first step to figuring out how many shingles you need is calculating the square footage of your roof. Going up on your roof is dangerous, so our method relies on measuring from the ground. This calculation will be pretty rough, but will give you a ballpark figure. Don’t let the math scare you – it’s actually pretty straightforward.

To find the square footage of your roof:   

  1. Outside your home, measure the length and width of your house. Measure from eave to eave, rather than corner to corner, to account for the roof’s overhang.
  2. If your house isn’t rectangular, measure the length and width of each section.  
  3. Multiply the length and width of each section to get the square footage. If your house is rectangular – you’re already done!
  4. Add the square footages of all sections together to get the total square footage of the roof.

Now, take your total square footage and divide it by 100. 

This will tell you how many “squares” your roof is. You’ll use the number of squares to figure out how many shingles you’ll need.

What should be covered in a roofing estimate template?

Generally speaking, this is what should to include in an estimate for a roofing job:

  • Total roof cost with detailed sections outlining labor and material costs.
  • Instructions from the customers and a description of all the work to be done.
  • Warranty information on the work done and the materials used.
  • How long the estimate is good for.

It’s a good idea to go over every estimate item with potential customers to confirm they understand exactly what’s being done and any conditions on that work.

If you bid on commercial roofing projects, the general contract owner may require specific information not mentioned here. Generally speaking, a list of what to include in your roofing bid is provided during the bidding process.

Calculating the Area of a Complex Roof

Areas of complex roofs with many hips and valleys take the most time to calculate. To get started, make a rough sketch of the roof. To simplify things, break down the sketch into rectangles and right triangles and then take as many measurements of the roof as you can to match the sides of the rectangles and triangles on the sketch.

Square lines off eaves edges or ridges can be determined by using visual cues from the existing roof. These will help you measure the lengths of the sides of the rectangles and triangles. For example, the cutout slots on shingled roofs run perpendicular to the eaves, and nail rows in sheathing are very close to square as well. While it can be challenging sometimes to get accurate measurements, don’t be too concerned and round lengths to the nearest 6 in.

When your sketch is filled in with measurements, determine the size of the roof area. The area of a rectangle is length multiplied by width, while the area of a right triangle is the length of the two sides that meet at the 90-degree corner multiplied together and divided by two.

How to Calculate Total Square Footage of Your Roof. To find your roof’s total square footage: Measure the length and width of each plane on the roof (including dormers) then multiply length times width. Add the square footage of each of the planes together.

What is a roofing square?

A lot of different factors determine the cost of your new roof. One of the biggest factors is the size of your roof that’s calculated by a measurement called a “roofing square”.

A roofing square is a 10×10 area that’s equal to 100 square feet of roof surface. The amount of roof squares determines how much roofing materials and labor it takes to replace your roof. 

The more squares your roof has, the more your roof replacement costs. Usually, it takes about 3 bundles of roofing materials (asphalt shingles) to fill a roofing square. 

But it ultimately depends on what type of roofing material you choose for your roof replacement. Some homeowners get confused by the term “roof square” and like to see the cost broken down by square footage. 

If this sounds like you, all you have to do is take the cost per square and divide it by 100. For example, if the cost of your roof is $600 per square, that comes out to $6.00 per square foot. 

If there’s any confusion about the terms you see on your roof estimate, don’t hesitate to ask the roofing contractor to explain them until you fully understand. 

Estimating Roof Area Using Pitch and Square Footage

If you are mathematically inclined or have a roofing calculator, you can estimate the roof area if you know the pitch of your roof and the square footage of your home. To illustrate, if your pitch is 4/12 and your two-story home has 1,400 square feet on each floor, these are the calculations.

• Divide the pitch. For a 4/12 pitch, the answer is 1/3.
• Square the above answer, which in this example would yield 1/9.
• Add 1, expressed as a fraction. That is, you would add 9/9 + 1/9 for a total of 10/9.
• Take the square root of 10/9, which is approximately 1.054.
• Multiply 1.054 by 1,400, the square footage of the home used in this example. You should get 1,475.6.
• Divide 1,475.6 by 100 to determine the number of squares required. You will need at least 14.756 squares of roofing. However, you should add about 10 percent for starter strips, valleys, waste and hip and ridge.

Measuring each roof plane requires you to actually go onto your roof. If your roof has a number of planes and numerous hips, ridges and valleys, this is the most accurate way to calculate the materials needed. Take a metal tape measure and a pen and paper. Measure each plane’s length and width. Record your measurements. Once you are safely on the ground, use your measurements to determine the square footage.

• For rectangular areas, multiply the length by the width. For example, if a plane measures 30 feet by 100 feet, this would be 3,000 square feet.
• For triangular areas, you may need to dust off your geometry book. If the area forms a right triangle, you can make use of the Pythagorean theorem. Otherwise, you might want to look up how to calculate the semiperimeter and then use Heron’s formula to find the area.
• Be sure to add extra for valleys, hips and ridges.

How to Calculate Roof Area

To calculate your roof area, simply multiply your roof length by your roof slope height, and multiply this by two. This should give you the total area of your roof, not accounting for a chimney or other sections of your roof not covered by tiles

Things You Will Need

  • Square footage of your house

  • Pitch of your roof

  • Calculator

  • Paper and Pen

Tip

This calculation will give a solid estimate for a single slope roof and a simple gable roof with a single pitch. For more complex roof lines with multiple pitch angles, it’s a little more complicated but the same steps can be followed; just break down the roof into separate sections with a different square footage for each different pitch angle.

Step 1: Sketch Roof Outline

Sketch the roof outline using ground measurements as shown in Figure 1 below. Knowing the longest dimension first will help you to scale your drawing appropriately.

Step 2: Fill in Roof Details

Measure and sketch out dormers, hips, valleys, diagonal distances and protrusions or overhangs. Chimneys, vents, skylights and pipe sizes will need to be measured to calculate trims and flashings needed for the job.

Pro Tip: You may need binoculars to count units of existing roof materials in unreachable areas. If different pitches exist on adjacent sides of a valley or hip, it’s length can be determined by treating the hip or valley as the diagonal (hypotenuse) of a right triangle on the roof pane next to it.

Roof Outline Plan Drawing

Figure 1. Sketching Your Roof Plan

Step 3: Determine Roof Pitch

Pitch refers to the angle of the roof, or how steep it is. Measured by inches of rise (vertical measure) over 12 inches of run (horizontal measure) In the gable diagram in figure 2. (below) there are 4 units of rise and 6 units of run. This can be converted to units of rise over 12 by understanding that cross products in step 2 must be equal. There Therefore 4 x 12 must equal 6 x X. Step 3 shows that X must equal 48 divided by 6. Therefore X equals 8 and the pitch is 8/12.

Formula for Calculating Roof Pitch

A Note About Pythagorean Theorem (Yes, You Need It in Real Life)

If you know the measurement of two sides of a right triangle, but not the third side, then the Pythagorean Theorem from 8th Grade geometry is your best friend. In Figure 2 above, rise squared (multiplied by itself) plus run squared equals the diagonal squared. In the diagram,  a+ b2 = c2. If the rise is 42 + 62 = c2, then 16 + 36 = c2 – So c = the square root of 52. Pythagorean Theorem tells us that the gable (diagonal) length is 7.21’ or about 7’ 3”.

Roof Pitches in Degrees

Step 4: Calculate The Simple Roof Areas

On a simple hip or gable roof, multiplying the eave to ridge length by eave length will give the area to be multiplied by pitch factor. Ridge vent openings are best finished with coil rather than partial shingle. Using flat coil stock allows the ridge caps to lay flat and can also be formed with an extra water stop at the ridge opening.

Area for the roof in Figure 3 is 1784 ftThe blue dash line divides the roof into 2 rectangles. There is a small area calculated as 8/12 that is actually 4/12. On a small area such as this, it is better to err on the side of the higher pitch since it should not significantly affect the total.

Pro Tip: Pythagorean Theorem can be used to calculate the length of the valleys. A general rule of thumb is to add at least 12” lineal inches of valley material to be safe.

Plan for Calculating Simple Roof Areas

Figure 3. Calculating Simple Roof Areas

Step 5: Calculate The Complex Roof Areas

Most roofs in Canada would be considered on the complex side. Multiple adjacent pitches, dormers, and turrets are common. Keep in mind that an experienced metal roofing contractor will need to factor in extended labour time for areas of your roof that will require precision metalworking skills.

Start by finding the “footprint” area and multiply by the correct slope factor determined by pitch (see Pitch Factor Chart bottom of page). In Figure 4 below, the dashed blue lines give a simplified view of the “footprint”. Multiply L x W to calculate the area for each rectangular section. Note the area of 77ftthat needs to be subtracted for the recessed area.

Once the “footprint” including overhang areas have been determined for each area, find the appropriate slope or pitch factor in the chart below. For example, a roof area with an 8/12 pitch has a slope factor of 1.202 so 2053ftx 1.202 = 2468fttotal roof area.

A Note about complex roofs: Complex roofs need more accessories and trims than“easy” roofs – resulting in a slightly higher total cost/square foot.

How to Calculate Area for Complex Roof

Figure 4. Calculating Complex Roof Area

Step 6: Measuring or Calculating Gable and Hip Lengths

 The slope factor is also used to determine gable lengths when the run length is known. For example, in Figure 4 the bottom left gable measures 16’ across from eave to eave and therefore has a run of 8’. When this is multiplied by 1.202 the gable distance is 9’8” (9.62’ rounded up to nearest inch). Note that this run can also be multiplied by the hip/valley factor of 1.563 to get a valley length of 12’6”.

Record all your calculations on your drawing as seen in Figure 5 below.

Acreage Calculator – Measure the area of a plot of land

The easiest way to measure the acreage of a plot of land is to start by entering an address that is associated with the plot of land you need the area of. In rural areas where an address may not be available, you can enter the cross street or even the GPS coordinate of a point on the land. For GPS coordinates be sure to enter the latitude followed a comma then the longitude ex. (41.87811, -87.629798). In any case this will place a marker that you can use as a reference point to draw the area on the map. Once you are finished drawing the area calculator will display the area of the shape above the map.

How to use the google maps area calculator tool to measure a roof

Special precautions must be taken when measuring the area of a roof. The images that appear on google maps are often at a slight angle, which combined with the angle of a roof can cause errors. For this reason it is best to outline the roof at points which are all at the same elevation. On a simple house for instance you would only click on the corners of the roof and not on any points along the peak as that would cause an error. After measuring the area of the footprint you can estimate the actual roof area based on the angle of the roof. Similarly if you using the area calculator tool to measure a roof with multiple levels, you should do the individual section separately. The google maps area calculator is not 100% accurate. Do not rely on this tool as your only resource in making important decisions.

CALCULATING THE AREA (ESTIMATED)

If you don’t want to do a lot of measuring, you can use your pitch calculation to get an estimated square footage of your roof:

  1. Once you have your roof’s pitch, divide the number by 12. (For example, if your roof’s pitch is 4 in 12, you would divide 4 by 12. This would yield 1/3.)
  2. Next, square your result. (If your number is 1/3, squared would yield 1/9.)
  3. After that, add 1 to your number. (1/9 + 1 = 10/9.)
  4. Next, figure out the square root of your new number. (The square root of 10/9 is 1.05.)
  5. Determine the square footage of one floor of your home. (For example, if you have a two-story home that’s 2,600 square feet, one floor would be 1,300 square feet.)
  6. Multiply this number by your most recent result to get the estimated square footage of your roof. (1,300 x 1.05 = 1,365 square feet.)

CALCULATING THE AREA (TRUE)

If you want to get the exact area measurement for your roof, you can follow these steps:

  1. Once you have your roof’s pitch, divide the number by 12. (For example, if your roof’s pitch is 4 in 12, you would divide 4 by 12. This would yield 1/3.)
  2. Next, square your result. (If your number is 1/3, squared would yield 1/9.)
  3. After that, add 1 to your number. (1/9 + 1 = 10/9.)
  4. Next, figure out the square root of your new number. (The square root of 10/9 is 1.05.)
  5. Next, use your measuring tape to measure the length of your house. (Be sure to include overhangs.)
  6. After that, measure the width of your house. (Be sure to include overhangs.)
  7. Multiply your house length by your house width to get the area. (For example, 40 feet x 30 feet = 1,200 square feet.)
  8. Next, multiply the area by your roof’s pitch. (1,200 x 1.05 = 1,260 square feet.)
  9. To allow for hips, ridges, and waste, add 10% of your final number for a gable roof and 17% of your final number for a cottage roof. (Your total number would be either 1,386 or 1,474 square feet.)

Method 2

Determine the roof area by using a mathematical formula that accounts for the roof length, total span, and roof pitch:

  1. Determine your roof pitch by using a pitch gauge (available at most home improvement stores) or a smartphone app (available free through any app store).
  2. Measure the length of the roof surface, including overhangs.
  3. Measure the span of the roof, including overhangs.
  4. Multiply the length x the span. The result will be the plane area. Use the chart below to calculate the total area of the roof.
  5. Calculate the total roof area – Plane Area x Correction Factor = Roof Area

How do I figure out how many squares my roof is?

Roof surfaces are measured in “squares”. A roofing square is equal to 100 square feet of the roof. To determine the number of squares on the gable roof example in this post, divide its total of 2400 square feet by 100 (2400 ÷ 100 = 24). This means you would need 24 squares of shingles to cover that roof.
 

What does a 7/12 pitch mean?

Roof Report by Blueprints

Once the drawing was exposed to light, the exposed parts turned blue, while the drawing lines blocked the coated paper from exposure and remained white. … For decades, bluelines were the way to make copies of architectural drawings. To this day, they are often called blueprints.

The most important thing is to match the scale of the ruler used for measurement to the drawing.

  1. Unroll the blueprint onto a flat surface. …
  2. Find the scale of the drawing. …
  3. Choose a scaled ruler that accurately matches the scale of the drawing. …
  4. Lay the proper scale next to the item on the drawing and take the measurement.

4 Tips for Reading Blueprints

  1. Begin with the title block. The title block is the first piece of information you’ll see in construction site plans. …
  2. Study the plan legend. …
  3. Find the blueprint’s scale and orientation. …
  4. Look for notes from the architect.
What Are the Six Types of Construction Drawings?
  • Plans.
  • Interior and exterior elevations.
  • Building and wall sections.

Drone Technology for Roof Inspection

According to roof inspection companies, using a drone allows them to finish jobs three times faster than if they did them using traditional methods. This capability also lets them offer more premium services because they can commit to shorter turnover times and more detailed roof inspections reports.

Nationwide, they cost an average of $150 to $400. The inspector flies a drone equipped with a camera over the roof, capturing close-up footage of all surfaces for the expert to analyze.

Do roofers use drones?

Drones used in roofing inspection is increasingly common across North America. Held in high regard in the construction and building inspection industries as well, drones in roofing have significant value. They make the inspection process go faster, lower costs, and there is no risk involved.
 
Increase productivity and improve safety. An aerial drone roof inspection can speed up the inspection process, and reduce the risk of work accidents and damage to the client’s property. It is also incredibly precise, with drone roof inspection measurements 95% accurate.

Drones Get the Job Done Faster

Any roof inspection requires a great deal of planning and preparation. Much of this is dedicated to ensuring the safety and compliance of workers.

With drones, however, it’s easier to carry out an inspection shortly after a client makes the request. Because drones don’t mount and climb access equipment, drone-based examinations begin immediately and take a fraction of the time of conventional methods.

Additionally, drones can transmit data to the inspection team immediately, which allows for faster report generation and less risk.

Features to look for in a drone for roof inspection:

  1. Flight stability – One of the most important features for drone roof inspection is stability. The drone must withstand the prevailing weather conditions including moderate and strong winds.
  2. High-resolution camera – When doing a roof inspection, you would want your videos and photos to be as detailed as possible. Nowadays, recording videos for professional use at a resolution below 4k is already unacceptable.
  3. Obstacle avoidance systems – To capture detailed shots or footage of a roof. Drone must fly close and low. It is not recommended to a drone to fly autonomously if it doesn’t come equipped with a good obstacle avoidance system.
  4. Thermal Camera – Thermal imaging cameras of drones allows inspectors to scan large areas for moisture trapped underneath roof membranes and look for the effects of structural issues. The thermal camera detects this temperature difference and displays it as colors – for example, dark tones indicating cold moisture or light tones indicating heat escaping through the uninsulated roof.
  5. GPS guidance/Satellite Positioning – Not only does it make controlling your drone much easier, but it also paves the road for many other advanced features which can be of great help, especially for a roof inspection. GPS allows several other smart flight modes including Orbit, Follow Mode, Waypoints etc.
  6. Long battery life – The longer the battery the better. Any drone that can fly for 25 minutes or more on a single battery cycle should do.
