Pinnacle Contractor Calculator

Roofing Calculator

Estimate roofing squares, shingle bundles, underlayment, labor, tear-off, and total job pricing by roof pitch and building size.

This is an estimate, not a bid or contract. Every job has unique conditions — access, structure, moisture, code — that software cannot account for.

Use at your own risk. Pinnacle Designs, LLC is not liable for bids, losses, or code compliance based on calculator output. You are responsible for verifying all numbers before use.

Terms of Service (limitation of liability & your responsibilities)

Always verify local building codes. Supplier prices vary by region. Add waste for cuts, mistakes, and damaged material.

Job Site Market (ZIP & Region)

Enter the job ZIP — not your shop — to load typical local labor and material defaults. Useful when bidding out of town or out of state.

Most U.S. ZIPs auto-select a region. Unknown ZIPs — pick the closest market manually.

Typical U.S. contractor rates, loaded ~5% above market average — adjust for your bid.

National Average — typical contractor labor ~$57.75/hr

Typical labor rates align with the national average.

Defaults load ~5% above typical market averages — a conservative benchmark when clients compare your bid. Edit any rate below for your actual numbers.

Regional defaults update labor, materials, markup, and tax in this calculator. Your job ZIP and region are saved across all calculators — change ZIP when you switch to a different job site.

Estimate — not a bid

Numbers from this tool are planning estimates only. They are not a contract, quote, binding bid, or professional advice. Every job carries its own challenges — hidden damage, tight access, moisture, local code, and scope details — that no calculator can see.

Each project is different. Access, existing conditions, code requirements, material choices, and your local market all affect the final price. Use these figures as a starting point — your actual price may vary.

By using this tool you agree you will not rely on it as a final bid without your own verification. See our Terms of Service for limitations of liability and your responsibilities.

  2. Adjusted area = flat area × pitch multiplier
  3. Squares = adjusted area ÷ 100

  5. Enter your ZIP or pick a region to load local labor & markup defaults

Frequently Asked Questions

Can I set pricing by ZIP code?
Yes. Enter your ZIP in the Your Market section — southeast Iowa ZIPs (525–527) load rural rates automatically. You can also pick a region manually and still edit every price field.
What is a roofing square?
One square equals 100 square feet of roof area. Three bundles of standard shingles typically cover one square.
Why is labor so different by region?
National defaults reflect urban/coastal contractor rates. Rural Midwest labor is often $120–$175 per square vs $250+ in high-cost markets. Always use your actual bid numbers.
