Cost by roof scope
Roof pricing moves on area, pitch, how many layers come off and what the deck looks like underneath. Every row is priced against the St. Louis median.
| Scope | What it includes | Typical installed cost |
|---|---|---|
| Overlay on a simple ranch roof | Single layer, 4:12 pitch, no tear-off | $900 – $1,100 |
| Standard tear-off and replace | One layer removed, architectural shingle, walkable pitch | $1,200 – $1,600 |
| Two-layer tear-off | Extra removal and disposal, same footprint | $1,400 – $1,900 |
| Steep or cut-up roof | 8:12+ pitch, multiple valleys, dormers, staging | $1,800 – $2,400 |
| Replacement with deck repair | Partial resheathing found after tear-off | $1,600 – $2,200 |
- • Tear-off and disposal is priced per layer — quotes that omit a second layer are the most common source of change orders.
- • Decking is unknown until the old roof is off. Reputable quotes state a per-sheet resheathing price up front.
- • Pitch above 7:12 requires fall protection and slows the crew, which shows up as labor, not material.
Basis: Each scope is priced as a multiple of the modeled St. Louis median for roof repair, so the scenarios, the size table and the calculator always agree. · Hometriva methodology

Frequently asked questions
What is the Florida 25 percent roof rule?
When more than 25 percent of a roof section is repaired or replaced within any 12-month period, the Florida Building Code generally requires the entire roof section to be brought up to current code, which in practice means a full replacement.
