This page is designed to help you get an estimate of square footage of your roof. Please remember this is only an estimate
Step 1: Draw your house footprint ( this would be considered a birds eye view looking staight down on
your House)
Step 2: Measure the outside of your house (remember to add for overhangs) If you have several "jogs"
in and out just measure as if straight.
Step 3: Multiply the outside measurements together (Lenght and Width) This number should close
to your square footage
Multiply by the roof slope factor. 3/12 pitch multiply by 1.04 4/12 pitch multiply
by 1.06 5/12 pitch multiply by 1.08 6/12 pitch multiply by 1.13 7/12 pitch multiply
by 1.17 8/12 pitch multiply by 1.21 9/12 pitch multiply by 1.25 12/12 pitch multiply
by 1.42
