What is a Square in Roofing?
A "square" in roofing is a unit of measurement equal to 100 square feet of roof area. It's the standard unit used by roof and solar installers to estimate materials and costs.
Why use squares? Roofing materials like shingles are typically sold by the square, and labor costs are often calculated per square. This makes it easier for contractors to provide accurate estimates.
Example: A roof that's 2,000 square feet equals 20 squares. If shingles cost $300 per square, the material cost would be $6,000 (20 squares × $300).
Understanding squares helps homeowners better understand estimates and material requirements when planning a roofing project.
