What is a square in roofing?

In roofing terms, a square equals 100 square feet of roof area. Contractors use this measurement when estimating materials and labor. For example:

• A 2,000 sq. ft. roof equals 20 roofing squares.
  
• Shingles, underlayment, and other materials are calculated by the square.
  

This helps standardize pricing and simplifies communication between homeowners and roofing contractors.
