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 2400 square feet by 100 (2400 ÷ 100 = 24). This means you would need 24 squares of shingles to cover that roof.
A square of shingles is the quantity needed to cover 100 sq. ft. of roof. Shingles are packaged in paper- or plastic-wrapped bundles designed to be light enough for a person to carry, so heavier shingles require more bundles per square.
Roofing square (or per square) is a common roofing terminology. It means “100 square feet.” It is used by contractors, suppliers, wholesalers, and manufacturers so that they have a common way to refer to 100 square feet of roofing material.
Steps to Measuring Roof Square Footage
- Prepare: For your safety, use a sturdy, reliable ladder and secure to your roof. Wear shoes (boots) with proper traction to avoid slipping.
- Measure: Use a tape measure to note the length and width of your roof, including dormers. Be careful walking around, so you don’t damage your roof.
- Calculate: Multiply the length by the width of each plane to determine square footage. Then add the results together for the total square footage of your roof.
