Frequently Asked Questions
How accurate is this roof replacement cost calculator?
This tool provides a planning-level estimate based on national averages and your inputs. Actual quotes may vary by local labor market and contractor.
Does the estimate include permits and disposal fees?
Yes, our estimate includes an allowance for permits, fees and tear-off disposal.
How do I measure my roof size?
Roof size in square feet is typically larger than your home's floor area due to overhangs and pitch — a roofing pro can measure precisely.
Why does roof pitch affect the cost?
Steeper roofs are more difficult and dangerous to work on, increasing labor time and safety equipment needs.
Should I tear off my old roof?
Tearing off the old roof is usually recommended for longevity, though installing over existing shingles can lower costs in some cases.
