Roof measuring tool

Measure the base area of your property
That will be the roof base width. Then, measure the distance of the other side of the structure from the edge of the eave to the other. That will be the roof base length. Multiply those figures together to get an estimate of the base area for the roof structure.

How Many Roofing Shingles Do I Need?
  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.


Simply locate a roof rafter board, place the end of the level against the bottom edge and measure from the 12-inch mark vertically to the bottom edge of the rafter. This will give you the rise over run, or pitch. For example, if you measure 4 inches, the pitch of your roof is 4:12.

How do you measure gutters from the ground?

Measure the length in feet of each roof edge where you will install seamless gutters, using a tape measure laid on the ground. Round the measurement up to the next whole foot. If the gutter must turn corners along the roof edge, measure the length in feet of each segment of the roof edge.

How do you measure a roof with a tape measure?

Image result
With your measuring tape, measure vertically from the top point to the bottom point of your roof. (This is also called the rise.) Repeat this over 12 inches, then place the measurement over “12”. (For example: If your rise is 4 inches over 12 inches, then your slope measurement is 4/12.). Follow Us for more details Please!

How do you estimate roofing costs?

Measure the square metre area of the roof you want replaced. The range of prices to replace your roof is: $50 to $95 per square metre. So multiple this rate against the square metre of the roof you want replaced.

Satellite Roof Measurement USA

Satellite temperature measurements are inferences of the temperature of the atmosphere at various altitudes as well as sea and land surface temperatures obtained from radiometric measurements by satellites. … Weather satellites do not measure temperature directly. They measure radiances in various wavelength bands.

Contractors will also be able to upload drone images or blueprints to measure. Once mapping is completed, the user receives a final, downloadable report on the area, pitch, direction, and edge lengths of the roof, which helps determine how much roofing material to purchase, the amount of time the project will take, and the total cost to the customer. Get to know more about our working Process! 

What does a satellite measure?

Satellites looking toward Earth provide information about clouds, oceans, land and ice. They also measure gases in the atmosphere, such as ozone and carbon dioxide, and the amount of energy that Earth absorbs and emits. And satellites monitor wildfires, volcanoes and their smoke.

How to Calculate Roof Area – DIY

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.)

Calculate the exact roof area

Follow these steps to figure out the exact area of your roof:

  • Take your pitch number and divide it by 12. For example, if your pitch is 4 in 12, you need to divide 4 by 12. The answer will be 1/3.
  • Next, you need to square your outcome. In our example, 1/3 squared will yield 1/9.
  • Thereafter, add 1 to your result: 1/9+1=10/9
  • Calculate the square root of your new number: The square root of 10/9 is 1.05.
  • Measure the length of your house – including the overhangs.
  • Measure the width of your house – including the overhangs.
  • Multiply the length of your house by its width to get the area. For example, 40 feet x 20 feet = 1,200 square feet.
  • Thereafter, multiply the area by the pitch to get the true roof area: 1,200 x 1.05 = 1,260 square feet. 

In order to allow for ridges, hips, and waste, it is advisable to add 10% of your final roof area for a gable roof or 17% in the case of a cottage roof. Follow Us!

As a result, you should be working with 1,386 sq. feet or 1,474 sq. feet for a gable roof or a cottage roof respectively. Get to know more about us!

Know Your Roof Type

There are three main types of roofs common on most of the homes in the Dallas area. There is the one-plained square or rectangle shed roofs that can be measured up in seconds. Another common roof is the gable which goes up one side, meets in a triangle, and then slopes down the back side. These are also easy to measure but involve a little bit of adding for the total square foot. Hip roofs are the third type and are a little trickier because they feature four triangle-typed shapes that angle up towards a central peak.

Get a Friend, Get On the Roof, and Measure Your Roof

The first way to measure your own roof involves physically climbing up with your tape and taking down the measurements. Roofs are measured in square foot so if you had a simple rectangle shed that was 12′ x 12′ you’d have 144 square feet you need shingled. Finding the square footage of a gable roof works in much of the same way, if the two plains are both 15′ X 30′ you’d have 450 square feet on both sides, or 900 square feet total.

Hip roofs require some geometric calculating to get the proper square footage. Generally hip roofs feature two trapezoids and two triangles. To calculate the area of a trapezoid you add the length of the bottom base plus the length of the top base and multiply it by the height. You take that number and divide it by 2 to get the area of one trapezoid base. The area of a triangle is calculated by taking the base multiplied by the height and dividing by two. Hip roof square footage is then figured by adding all the sides together.

Roofing Materials

The purpose of calculating the precise measurements of a roof is to ensure that the appropriate amount of roofing materials are ordered – whether you have a shingles roof, gable roof or metal roof. Here are some common roofing materials and considerations for each:


Shingles are typically sold in bundles. Depending on the type and brand of shingle, it may take a different number of bundles to make a square. When cost comparing shingles, remember to base price on squares and not on bundles.

Metal Roofing

Metal roofing is typically sold by the sheet or panel. To determine the number of sheets or panels necessary to cover the roof, divide the width of the roof by the sheet or panel coverage width.

Other Roofing Materials

The basic square footage and length calculations detailed above should help estimate overall cost for other materials. Additional roofing materials that should be accounted for include items such as leak barrier, deck protection, drip edge, rake edge, ridge vents, and hip and ridge caps.

How do I calculate the size of my roof?

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.) Follow Us for more details Please!

What is the most common roof pitch?

Conventional slope roofs are most common with residential roofs. This means the slope has a pitch between 4/12 and 9/12 on most homes. Roofs with a pitch exceeding 9/12 are called steep slope roofs.

How do you calculate rafter length?

If you are calculating rafter length from the center of the ridge beam (as shown below), you will need to subtract half of the thickness of the ridge beam from the top end of the rafter. For example, if the ridge beam is 1.5 inches thick, subtract 3/4 of an inch from the overall rafter length.
Rafter Dimensions

As roof pitch is lowered, the weight burden on the rafters increases. For low-pitch roofs, building codes may require larger dimension rafters.

How far can a 2×6 rafter span without support?

How Far Can a 2×6 Rafter Span? A 2×6 rafter can span 14 feet 8 inches when spaced 16 inches apart with No. 1-grade southern pine lumber on a roof with a 3/12 slope or less with a maximum live load of 20 pounds per square foot and a dead load of 15 psf.

Learn How To Measure a Roof From Blueprints

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.

How do you measure for a new roof?

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.

How do you measure roofing materials?

Measure the length and width of each portion of the roof, multiply length by width for each plane, and then add the planes together for the total square footage. If you have a simple gable roof, you’ll only need to measure and sum up the 2 planes of the roof. Follow Us.

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.)


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
