Frequently Asked Questions

One roofing square equals 100 square feet. 3-tab shingles run 3 bundles per square, architectural shingles run 4 bundles per square, and luxury designer shingles run 5 bundles per square. Multiply your roof's total squares by the bundles-per-square for your shingle type, then add 10–15% for waste. The calculator above does this instantly.

For a rough estimate, take your home's ground-level square footage and multiply by about 1.3 for a typical two-story roofline (1.0 to 1.5 depending on pitch and overhangs). The most accurate method is measuring each roof plane's length times width and adding them together. Proof Construction offers free on-site measurements — call (918) 734-4444.

A roofing square is the industry unit of measure: 100 square feet of roof surface. Shingles, underlayment, and labor are all priced per square, so knowing your total squares is the first step to an accurate material order.

Most roofers add 10–15% waste to cover cutoffs at hips, valleys, and ridges, starter strips, and a few damaged bundles. Steeper or more complex roofs with many valleys need closer to 15%. This calculator defaults to 10% and lets you adjust the factor up or down.

Yes. Plan on roughly $0.10–$0.15 per square foot for roofing nails and fasteners and $0.08–$0.12 per square foot for synthetic underlayment. Both are included in Proof Construction's installed quotes, so you never have to source them yourself — call (918) 734-4444 for exact pricing.
