Cost by project size
Generated from the same unit pricing the calculator uses.
| Project size | Estimated range |
|---|---|
| 700 sq ft of roof area | $5,300 – $14,000 |
| 1,000 sq ft of roof area | $7,500 – $20,000 |
| 1,200 sq ft of roof area | $9,000 – $24,000 |
| 1,600 sq ft of roof area | $12,000 – $32,000 |
| 2,100 sq ft of roof area | $15,800 – $42,000 |
Based on West Palm Beach pricing of $8–$20 per sq ft of roof area.
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 West Palm Beach median.
| Scope | What it includes | Typical installed cost |
|---|---|---|
| Overlay on a simple ranch roof | Single layer, 4:12 pitch, no tear-off | $10,500 – $13,900 |
| Standard tear-off and replace | One layer removed, architectural shingle, walkable pitch | $14,400 – $19,400 |
| Two-layer tear-off | Extra removal and disposal, same footprint | $16,900 – $22,800 |
| Steep or cut-up roof | 8:12+ pitch, multiple valleys, dormers, staging | $21,100 – $28,700 |
| Replacement with deck repair | Partial resheathing found after tear-off | $19,400 – $27,000 |
- • 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 West Palm Beach median for flat roof replacement, so the scenarios, the size table and the calculator always agree. · Hometriva methodology
