Roofing Quote Footage is Not the Same as Home Square Footage

Depending on where the information is coming from is going to determine the basis on which the estimated roof footage is calculated. The roof square footage is what we (roofing contractor) need to calculate a budget quote to do the job.

Measuring the Roof’s Pitch

The incline or pitch of a roof can be easily measured with a level, tape measure, and a pencil. The roof’s pitch is the number of inches the roof rises in 12 inches. Therefore, mark off 12 inches on the level and place it down horizontally against the roof rafter.

Next, measure vertically from the 12-inch mark on the level straight up to the underside of the rafter, as illustrated below. That measurement is the number of inches the roof rises in 12 inches.

Some homes will have roofs with multiple pitches. Porches and dormer windows, for example, can have a different pitch from that of the rest of the house. For an accurate surface area measurement you should make note of these additional structures.

Using the table below, lookup the pitch/es and make a note of the number/s in the multiplier column. 

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.

A roofing square is an area of roof that measures 10 by 10 feet to make up a total of 100 square ft. This critical unit of measurement helps your contractor determine how much material they’ll need to order for your roofing project, from underlayment to bundles of roof shingles.
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.
 To calculate this is simple: a roofing square is 100 square feet, which means that 20 roofing squares will accommodate a 2000 square feet roof. To obtain 20, you need to divide the total square feet by the size of one roofing square- 100 square feet.
That makes a total of 32 squares of roof for an “1800 square foot” house. 4) Roofers calculate roof area in “squares,” with a square being 100 square feet of roof area.

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.

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.

Here’s a step-by-step guide to measuring with blueprints:

  1. Open the app and select “Measure Your Roof.”
  2. Select “Sketch My Roof.”
  3. Retrieve your blueprint image by tapping “Load,” then selecting the source of the file, i.e., your email, Dropbox, etc.
  4. Select the blueprint you wish to measure.

Roofing blueprints include:

  • Roof Type
  • Roof Materials
  • Roof Ridge Covering
  • Roof Ventilation
  • Roof Overhang
  • Roof Pitch

Creating Roof Blueprints

While it’s possible to create your own roof blueprint using software or online tools, this is a task that is often best left to the pros – especially for new roof construction.

Many roof designers and architects now create roof plans in 3-D. 3-D blueprints will provide a complete roof visualization that includes bridges, rakes, eaves, intersections, and runoff calculations for inclement weather conditions. A roof blueprint can also be used to diagram proper venting to protect a home or business from moisture buildup that can lead to mold growth.

ROOF SLOPES

Rise & Run Roof SlopeThe roof slope is defined by the rise (in inches) per 12 inches of run of the roof. For example, a “4 in 12 roof” is a roof that rises 4 inches for every 12 inches of horizontal run.

The formula to find the slope of a roof is:

Slope = Total Rise/Total Run

Roof Slope = Rise (in inches)/12 (inches per foot of run)

Roof Slope = (Total Rise/Total Run) x 12

How to Measure a Roof From the Ground?

Techniques for How to Measure a Roof From the Ground

For rectangular roof sections:

  1. On standard gable roofs with rectangular sections, you can count the shingles and calculate the size. This works because 3-tab shingles are about 12 inches wide by 6 inches high.
  2. Working left to right, count how many shingles that you see in a row.
  3. The number of shingles represents the section’s width in feet.
  4. Write down the width number.
  5. Count the rows of shingles upward from the gutter to the peak.
  6. Divide the row number by 2 to arrive at the height of the section in feet.
  7. Write down the height number.
  8. Multiple width by height to calculate square footage for the section.
  9. Repeat the shingle count method for every section of roof.
  10. Add all square footages for each section to get the total square footage covered by shingles.

Slope

Slope is the incline of the roof expressed as a ratio of the vertical rise to the horizontal run, where the run is some portion of the span. This ratio is always expressed as inches per foot.

Slope Ratio

A roof that rises 4 inches for every 1 foot or 12 inches of run is said to have a “4 in 12” slope. If the rise is 6 inches for every 12 inches of run, then the roof slope is “6 in 12.”

The slope can be expressed numerically as a ratio. The slope ratio represents a certain amount of vertical rise for every 12 inches of horizontal run. For example, a “4 in 12” slope can be expressed as the ratio of 4:12. A “6 in 12” slope is expressed as 6:12.

 

Pitch

Pitch is the incline of the roof expressed as a fraction derived by dividing the rise by the span, where the roof span is the distance between the outside of one wall’s top plate to another.

Degrees converted to roof pitch

9.5° = 2:12,  14° = 3:12,  18.5° = 4:12,  22.5° = 5:12,

26.5° = 6:12,  30° = 7:12,   33.5° = 8:12,   37° = 9:12,

40° = 10:12,    42.5° = 11:12,   45° = 12:12

Measuring the area of your roof is not always a simple process. In fact, it can be challenging to determine the square footage, especially if you have an irregular-shaped roof or if your roof has multiple dormers, valleys, hips, and ridge lines. However, getting a precise measurement is crucial if you want to purchase the correct amount of materials. If you are not confident in your ability to get a precise measurement, or if you do not feel comfortable going on your roof, consider hiring a professional to make the measurements and calculations for you.

How Many Bundles of Shingles Will You Need

The average bundle of shingles covers 33.3 ft2, so three bundles of shingles are needed per square. Asphalt shingles range in price from about $25 per bundle for a standard 3-tab style to around $50-$75 or more for an upgraded architectural style.

How Many Rolls of Felt Will You Need

Roofing felt is sold by the roll. The average roll of 15-pound roofing felt covers about 400 ft2, or 4 squares, while the average roll of 30-pound roofing felt covers about 200 ft2, or 2 squares.

Rolls of felt are 36″ wide x 144′ long for 15# and 72′ long for 30#. Consider other underlayment options as needed, such as rubber or tar products.

How Many Nails Will You Need

Nails will also be required for any roofing project. The average 3-tab shingle needs four nails per shingle. High wind areas and other types of shingles may need more. 320 nails will be needed to install a square of standard 3-tab shingles, assuming four nails per shingle and 80 shingles per square.

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.

How to measure a roof for shingles calculator

This makes it relatively easy to figure out how many shingle bundles your roof requires: simply multiply the number of roofing squares by three. If your roof’s area were equivalent to about 20 roofing squares, then you would need about 60 bundles of shingles.
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.
Thus, to cover roof of a 1500 square foot house, you would need 57 bundles of shingles. Thus, it will take 57 bundles of 3-tab standard size shingles (12″×36″) to cover roof of 1500 square feet house. Thus, there are 57 bundles of standard size 3-tab shingles you will need to cover roof of 1500 square feet house.
Asphalt shingles and most other roof shingles are typically available in bundles. For each roofing square or 100 sq ft, you will need three bundles of shingles. The average size of 12×12 shed roof is 3 squares, which typically requires 9 bundles of three-tab asphalt shingles or any other starter strips.
roof size calculator by address
A package of shingles is called a bundle. There are between 15 and 29 shingles in a bundle. A bundle typically covers 33 square feet regardless of shingle type. Divide total square footage by 33 to find how many bundles you need.
You will need approximately 42 bundles of standard size 3-tab asphalt shingles (14×3 = 42 bundles) or 56 bundles of architectural shingles (14×4 = 56 bundles) for 1,400 square feet. Thus, for a 1400 square foot gable roof, you would need 42 bundles of shingles plus 10% of ridge, starter and wastages.
How many roofing squares is 1600 square feet? 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.

Roof Measurement Report for RESIDENTIAL Roofs

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. For setting up the roof graphs we just need the location of the structure and we can give you the roof outline of the structure with definite precision. The estimations are taken from satellite and ethereal pictures that are regularly as, or more precise, than estimations taken from the site. We are comfortable working with Google Earth, BING, and Pictometry picture sources. Our twofold check quality methodology helps us giving quality yield to our clients.

In most cases, satellite and aerial roof measurement technology is 99% accurate, if you follow a few simple rules. Achieving accurate roof measurements manually isn’t any different. A manual roof takeoff by one roofer can easily vary from that of another.
How much does a roof replacement cost? It will cost anywhere between $6,000 to $9,000 to replace a typical 1,700 square foot asphalt shingle roof. Roofing companies charge an average of $3.50 to $6.00 per square foot for asphalt roof replacements.
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.

Satellite Reports: Fast, Accurate Roof Measurements Reports

In most cases, satellite and aerial roof measurement technology is 99% accurate, if you follow a few simple rules. Achieving accurate roof measurements manually isn’t any different. A manual roof takeoff by one roofer can easily vary from that of another.
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.
To estimate roofing materials, start by finding the total square footage of the roof and divide the number by 100 to determine the number of “squares” in the roof. Since it takes 3 bundles of shingles to cover a square, plan to purchase 3 bundles for each square. Then, add 10% to the number to account for waste.

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.
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.
The more architectural details your roof has, the more planes you will have to measure. Measure each plane.Find the length and width of each plane.Then, multiply those two numbers together to find the square footage of that plane.

They generally range between $55 on the low end and $600 on the high end, with an average of $100 to $250 per square of architectural shingles.

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.
 
Estimate the cost of a new roof online
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 A New Roof Cost?

The national average cost to replace a roof is around $8,000, with most people spending in the range of $5,500 to $11,000. The two largest variables you’ll deal with on a job like this are the square footage of your home (and thus, your roof), and the type of roofing material you choose.

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.

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 do I calculate roof covering area?

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.)

Divide the total roof area by 32 to get the number of sheets you will need to cover the roof. A typical 4 foot by 8 foot sheet of plywood covers 32 square feet. If your roof area is 1,600 square feet, 1,600 divided by 32 will mean you need about 50 sheets to cover the roof.
1 square is equal to 100 square feet of the roof. To determine the amount of squares you’ll need for your old or new roof, just divide the total square footage by 100. The number of bundles you’ll need for your home will depend on how many squares your roof is.

Depending on where the information is coming from is going to determine the basis on which the estimated roof footage is calculated. The roof square footage is what we (roofing contractor) need to calculate a budget quote to do the job.
Foam backed polycarbonate and clear polycarbonate roofing options are the most commonly used types of polycarbonate sheets. Foam-backed polycarbonate roof sheets are lightweight and durable. They are installed in industrial buildings, like warehouses, because of their longevity and strength.
These single wide homes all have 3-bedrooms, 2-bathrooms, and a single living room. They all include kitchen appliances as well. The homes are 1140-1178 square feet.

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.

Cost of Shingles

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

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.

Benefits of Roof Measuring Software

 

There are many benefits to investing in software to help you measure roofs.  Let’s take a look at four key reasons why it makes sense to purchase roof measuring software:

  1. Save Time – if you’re measuring roofs on blueprints, it can be tedious to get out a scale ruler and measure each twist and turn of the roof and then calculate areas by hand. It’s much quicker to just click your mouse a few times to measure your roof and let the software do the calculations.
  2. Increase Accuracy – It’s easy to measure wrong or plug in the wrong number into your calculator. Calculation mistakes mean you could order too much or too few materials.  These mistakes are not only annoying, they are costly too! 
  3. Save Money – Printing blueprints is expensive and inconvenient. With roof measuring software, you won’t have to print anything.  Just upload your plan pages into the software and measure!  You’ll save money every time you won’t have to print out blueprint pages.
  4. Convenience – If you’re working on an existing building, you won’t have to actually drive to the location to do your measurements in person. Time is money, and you’ll be saving a lot of time not having to visit your location in person.

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′.

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.

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. For example, this flat roof has one roof plane.

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).

How To Measure a Roof From Blueprints

Measure a roof from blueprints.

Building a brand new home obviously involves a brand new roof. The more traditional way of scaling out blueprints (roof plans) is to do it by hand using various tools such as a tri-ruler and other utilitarian items. But, some roofing contractors are leveraging high-tech to their advantage by using aerial and satellite technology to measure, and roofing applications to save time and money.

The architects who create the blueprints don’t always anticipate the specific needs of the contractors who will perform certain jobs on the property, such as constructing the roof. The architects’ drawings are often too complex for roof bidding purposes.

Having only a blueprint for a new home doesn’t mean that a roofing contractor must put aside their high-tech roof measurement and estimating application and pull out the ol’ tri-ruler.

To find your roof’s total square footage:
  1. Measure the length and width of each plane on the roof (including dormers) then multiply length times width.
  2. Add the square footage of each of the planes together.
In addition to being a larger unit of measurement, a square is used so that there’s a standardized measurement no matter the layout or shape of the roof. For example, 10′ x 10′ is equal to 100 square feet, or one square. 4′ x 25 ‘ is also equal to one square. Both of these would require one square of material to cover.

In most cases, satellite and aerial roof measurement technology is 99% accurate, if you follow a few simple rules. Achieving accurate roof measurements manually isn’t any different. A manual roof takeoff by one roofer can easily vary from that of another.
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.)
  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.
Method
  1. Find out what the scale on the drawing is.
  2. Measure the distance on the drawing using a ruler (or count the number of squares, if that’s an option).
  3. Multiply the distance you measure by the scale to give the distance in real life.
