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.

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.

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?

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.

Here’s a roofing inspection checklist:
  1. Cracked caulk or rust spots on flashing.
  2. Shingles that are buckling, curling, or blistering.
  3. Missing or broken shingles.
  4. Cracked and worn rubber boots around vent pipes.
  5. Missing or damaged chimney cap. …
  6. Masses of moss and lichen, which could signal the roof is decaying underneath.

What will fail a roof inspection?

Common roof problems found in home inspections include a failing structure (sagging), poor installation or workmanship, leaks, missing/damaged shingles, improperly installed flashings, and clogged gutters and downspouts.

Should I get my roof inspected?

  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.

How do you measure a roof with a tape measure?

Ask the assistant to hold one end of the tape in line with the outer edge of the roof at one end, and measure to the opposite, outer end of the roof. Multiply the angle measurement for the pitch of the roof by the length of the roof to determine the square-foot area of one side of the gable.

How do you calculate the area of a roof without pitch?

Figure the area of small sections, such as crickets at the back of a chimney or short hips, by multiplying the length times the width at the widest point instead of using exact measurements.
aerial roof measurement

How do you calculate the area of a sloped roof?

Determine the area protected by the sloping roof by multiplying the length of the roof by the width. The result is the area covered by the sloping roof. For example, a single sloping roof covering a house 30 feet long and 20 feet wide covers an area of 600 square feet — 30 x 20 = 600.
