What Is A Roofing Square? Roofing Calculator

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.

Squares are also used to identify the amount of underlayment your roof requires. So, using the same example and formula above, you’ll also need 120 squares of underlayment for a roof with a square footage of 12,000. Most—if not all—companies that offer residential roofing in Naperville, Illinois and in other cities in the U.S. offer underlayment in rolls of four (4) squares each. As such, if your roof requires 120 squares, you will need 30 rolls (120 ÷ 4 = 30) of underlayment from roofers.
 

Roofing Pitch for Square Roof Area

Finally, the more complex part, measuring your roof’s pitch.

  1. Estimate or calculate the pitch of your roof .
  2. 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. 
  3. 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.
