How This Calculator Works
Our calculator uses real 2026 pricing data from Pinellas County roofing contractors to estimate your total roof replacement cost. Here's what it factors in:
- Home footprint to roof area: We apply a pitch multiplier because steeper roofs have more surface area. A 4/12 pitch adds about 5%, while a 12/12 (45-degree) pitch adds 41%.
- Material cost range: Each material has a per-square-foot range based on current Florida pricing including labor, materials, tear-off, disposal, underlayment, and permits.
- Story adjustment: Multi-story homes cost 10-20% more due to the added difficulty and safety requirements of working at height.
What the Calculator Doesn't Include
No online calculator can account for everything. Factors that could change your actual cost:
- Decking repairs (rotted plywood replacement: $50-75 per sheet)
- Ventilation upgrades ($300-1,500)
- Unusual roof complexity (multiple dormers, turrets, steep valleys)
- Access difficulty (narrow driveways, landscaping, power lines)
- Code upgrades required by the 25% rule
