Sq Ft Of Roof

Assuming this is a hip roof we multiply this by 1 1 which gives us roughly 18 squares or 1 800 square feet of the roof surface.
Sq ft of roof. 1 ft x 1 ft. For estimating purposes we also assume that there is a chimney a couple of dormers and two layers of old shingles that need to be torn off and removed before a new roof can be installed. To conclude the example if your total roofing area is 17 300 square feet your waste allowance would be 17 300 x 1 1 730 square feet. 1 roofing square 9 290304 m 3.

Link to your exact conversion. It is often compared to slope but is not exactly the same. 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. Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run.
The total amount of roofing material you need is 17 300 1 730 19 030 square feet.
