How Do You Measure The Square Footage Of A Roof

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.

How do you measure the square footage of a roof.

To convert the square footage to roof squares divide the square footage by 100. 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. 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. Things you will need steel tape measure.

Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy. Make sure to document the number of chimneys skylights or other obstructions and include dormers in your measurements. The roof surface area would be 24. 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.

The result is the total square footage of your roof. 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. 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.
