Roofing is not a safe DIY project
Falls from a single-story roof cause serious injury. This calculator helps you plan and verify quotes — most homeowners should hire a licensed roofer.
What this assumes
- One roofing square equals 100 square feet of roof surface.
- Standard architectural shingles require 3 bundles per square; high-wind zones require 4.
- Ridge cap coverage is approximately 35 linear feet per bundle.
