How Do You Measure Square Footage Of A Roof

Once you have your roof s pitch divide the number by 12.

How do you measure square footage of a roof.

A square simply refers to a 10 x 10 square of roofing. 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. This would yield 1 3 next square your result. Include dormers the small outjuttings over attic windows.

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. Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy. Calculate each plane separately. Convert the area to roofing squares.

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. Make sure to document the number of chimneys skylights or other obstructions and include dormers in your measurements. Multiply the length and width of each square or rectangle shaped plane. Measure the length and width of every roof plane or surface.

How do you calculate square footage for a roof. The roof surface area would be 24. Multiply the length by the width to arrive at. The calculator cannot account for complex shapes based on a measurement of square footage alone.

This is simply 100 square feet of 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. For example if your roof s pitch is 4 in 12 you would divide 4 by 12. How to calculate square feet of a roof. 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. To convert the square footage to roof squares divide the square footage by 100.
