Roof surfaces are measured in “squares”. A roofing square is equal to 100 square feet of the roof. To determine the number of squares on the gable roof example in this post, divide its total of 12,000 square feet by 100 (12,000 ÷ 100 = 120). This means you would need 120 squares of shingles to cover that roof.

Roofing Pitch for Square Roof Area
Finally, the more complex part, measuring your roof’s pitch.
- Estimate or calculate the pitch of your roof .
- Climb to the peak of your roof. Bring a two foot level. Hold your level outward, perfectly horizontal from your roof, so the bubble is in the middle of the indicator glass. Then, using a tape measure, determine how many inches are between the middle of your level and your roof.
- Multiply the number of roofing squares by the following digits below.
Low Pitch: 1.07 x Roofing Squares
Medium Pitch: 1.185 x Roofing Squares
High Pitch: 1.36 x Roofing Squares
Please note that we recommend letting a professional roofer do the calculations for your own safety!
Calculating a roofing square of your roof is very important, if you’re communicating with someone from the industry.
