Florida Roof Cost Calculator
Roof size × pitch × material × your city's real per-square-foot rate. Rates derive from contractor quote ranges and county permit records across the Treasure Coast and Palm Beaches — the same data behind our city guides.
What's a roofing square?
One square = 100 sq ft of roof surface. Contractors price jobs, order shingles, and quote tear-off in squares. A typical 2,000 sq ft single-family roof is a 20-square job. Your roof's surface is bigger than your home's footprint — pitch adds area:
| Pitch | Slope | Area vs footprint |
|---|---|---|
| Low | 2/12–4/12 | +5% |
| Average | 5/12–7/12 | +13% |
| Steep | 8/12–10/12 | +25% |
| Very steep | 11/12+ | +40% |
Multipliers are standard roofing-industry pitch factors, rounded for planning use.
Methodology
Per-square-foot rates are derived from the whole-roof replacement ranges published on each city guide (compiled from contractor quotes, county permit records, and published rate data), assuming a typical 2,000 sq ft roof. Cities without verified replacement-range data are excluded. Estimates exclude structural decking repair, which is priced after tear-off.

FAQ
Is this estimate a quote?
No — it's a planning estimate from local range data. Get at least three written, itemized quotes from licensed Florida (DBPR) contractors before committing.
Why is my quote higher than the estimate?
Quotes reflect tear-off layers, decking repair, upgraded underlayment, ventilation work, and permit fees. Florida's wind-load code requirements also add engineering scope that varies by county.
