How Do You Measure Square Footage Of A Roof

For instance if the roof is 1550 square feet then it is 16 squares.

How do you measure square footage of a roof.

Multiply the length by the width to arrive at. In cases where a roof has a complex shape such as in the image to the right measuring the dimensions and areas of each part of the roof to calculate total area will result in a more accurate measurement of area. The result is the total square footage of your roof. 1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square.

Add the square footage for all the planes together. Measure the ground dimensions of the house using a tape measure and write down these dimensions. Because each 100 square feet of roof is one roofing square divide. A square simply refers to a 10 x 10 square of roofing.

To find the squares divide the overall roof area by 100 and then round up. 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. 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.

How do you calculate square footage for a roof. 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. The roof surface area would be 24. Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy.

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. 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. 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. This is simply 100 square feet of roof.

To convert the square footage to roof squares divide the square footage by 100. Use the instructions for obtaining roof slope to add to your ground measurements. Make sure to document the number of chimneys skylights or other obstructions and include dormers in your measurements.
