How Do I Get Estimate Of Sq Ft Of Roof

Step 4 divide any irregularly shaped areas of the roof into more manageable triangles and rectangles then calculate square footage for those individual elements and add them to get the total square footage.

How do i get estimate of sq ft of roof.

How to estimate roofing materials.

For instance if the roof is 1550 square feet then it is 16 squares. Calculate the square footage area of a hip roof.

Because each 100 square feet of roof is one roofing square divide the total area from step 1 by 100. 1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square. Divide your estimated square footage by 100 to estimate your materials. To find the squares divide the overall roof area by 100 and then round up.

Although roofing projects are estimated and sold by the square roofing material is often not sold in 1 square increments.

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. This free roofing calculator estimates the area of a roof and the amount of materials required to replace or build said roof. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.
