How Do You Measure Square Footage Of A Roof

How do you calculate square footage for a roof.

How do you measure square footage of a roof. Measure the ground dimensions of the house using a tape measure and write down these dimensions. How to calculate your roof square footage first measure the length and width of each surface on the roof then multiply these values to get the square footage of that surface. Get the square footage of roof and divide it by 100 and it will give the number of squares you need and for every decimal number over 3 buy a bundle to achieve the amount of material. Multiply the length by the width to arrive at.

This is simply 100 square feet of roof. Add the square footage for all the planes together. If your roof is flat or has no more than a 3 in 12 pitch you can calculate its total square footage by simply multiplying the length by the width. Make sure to document the number of chimneys skylights or other obstructions and include dormers in your measurements.

Because each 100 square feet of roof is one roofing square divide. If its pitch is 6 in 12 a pitch multiplier of 1 12 multiplying 1 152 sq ft 107 0 m 2 by 1 12 would give you an overall square footage of 1 290 square feet 120 m 2. If for example the total square footage for the examples used so far would be 14 400 the rectangular plane plus 900 the triangle plus 2 000 the irregular shape 17 300 square feet. To find the squares divide the overall roof area by 100 and then round up.

The result is the total square footage of your roof. Measure the sides of your area convert all of your measurements to feet if you measured in feet skip to calculate the area as square footage if you measured in feet inches divide inches by 12 and add that to your feet measure to get total feet. The calculator cannot account for complex shapes based on a measurement of square footage alone. 1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square.

If your roof measures 48 feet 15 m x 24 feet 7 3 m multiplying its length by its width would give you a square footage of 1 152 square feet 107 0 m 2. A square simply refers to a 10 x 10 square of roofing. Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy. For instance if the roof is 1550 square feet then it is 16 squares.

Use the instructions for obtaining roof slope to add to your ground measurements. If you use ground measurements to determine your roof squares you will need to also compensate roof overhang and slopes to get an accurate count. Convert the area to roofing squares.
