Cost by project size
Generated from the same unit pricing the calculator uses.
| Project size | Estimated range |
|---|---|
| Minor repair (under 100 sq ft) | $200 – $2,600 |
| Moderate repair (100–300 sq ft) | $400 – $5,200 |
| Major repair (300–600 sq ft) | $700 – $8,800 |
| Repair with decking replacement | $1,000 – $13,000 |
Based on Duluth pricing of $450–$5,150 per repair.
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 Duluth median.
| Scope | What it includes | Typical installed cost |
|---|---|---|
| Overlay on a simple ranch roof | Single layer, 4:12 pitch, no tear-off | $900 – $1,200 |
| Standard tear-off and replace | One layer removed, architectural shingle, walkable pitch | $1,300 – $1,700 |
| Two-layer tear-off | Extra removal and disposal, same footprint | $1,500 – $2,000 |
| Steep or cut-up roof | 8:12+ pitch, multiple valleys, dormers, staging | $1,900 – $2,600 |
| Replacement with deck repair | Partial resheathing found after tear-off | $1,700 – $2,400 |
- • 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 Duluth median for roof repair, so the scenarios, the size table and the calculator always agree. · Hometriva methodology
