Get an instant 2026 budget range based on national installed pricing, adjusted for your region — then let real local quotes confirm your exact number.
Roof area is typically 1.2–1.6× your home's footprint depending on pitch. HVHZ regions (Miami-Dade, Broward, Palm Beach) carry higher permitting and fastening costs. Related: the full Roofing cost guide.
How this estimate works
The calculator multiplies your project size by 2026 national installed price ranges for the selected option, then applies a regional cost index. It intentionally returns a range, not a single number — real quotes vary with access, prep, code requirements, and current local demand. On mid-size projects the spread between the highest and lowest licensed quote routinely runs 20–40%, which is why comparing at least two quotes matters more than any calculator.
Frequently asked questions
How accurate is this roof cost estimate?
It uses 2026 national installed price ranges per square foot adjusted by region. Your actual quote depends on pitch, tear-off layers, decking condition, and local permit costs — treat this as a budgeting range, then compare real quotes.
How do I estimate my roof's square footage?
Multiply your home's footprint by 1.2 for a low-pitch roof, 1.4 for average pitch, or 1.6 for steep pitch. A 1,500 sq ft single-story home with average pitch has roughly 2,100 sq ft of roof.
