A handy table for calculating roof area.

To find the area of a roof, multiply the length by the width by the multiplier.
Make sure to add the overhangs!

Example: To find the number of squares of shingles needed for a

24' x 30' garage
with 2'0" overhangs, and 1'0" eaves at the gable ends. 6/12 pitch.

(30 + 2) x (24 + 4) x (1.1180) = 1001.728 square feet

Divide by 100 to find squares. You will need 10.02 squares of

shingles.

The amount of roofing material needed will exceed the area of the roof

Due to waste.  This varies based on the complexity of the roof

From 10 to 15 per cent.

To Determine Your Roof Pitch

• Place a level against the roof as shown.
  

• From the point where the level touches the roof, measure out 12 inches.
  

• From this point measure the distance in inches from the bottom of the level to the roof.
  

• This will be the first number in the roof pitch. the second number will
  

• always be 12.
