Prices to reroof a house are typically quoted per square (100 square feet). The cost per square varies by roofing material, labor market, roof complexity, and disposal. This article breaks down exact price ranges and components for planning a reroof project.
Assumptions: Midwest labor rates, standard asphalt shingle materials, normal ladder access, no structural repairs, and typical old roof removal where needed.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Reroof cost per square (asphalt shingles) | $350 | $450 | $800 | Includes removal and installation for typical detailing |
| Total project per square (average home, 18–22 squares) | $6,300 | $9,900 | $21,600 | Assumes standard home with dormers excluded |
| Labor per square | $180 | $240 | $350 | Hourly rates vary by region |
| Materials per square | $120 | $180 | $300 | Shingle type and underlayment influence |
| Removal/disposal per square | $50 | $80 | $120 | Depends on old material and debris haul |
| Permits and inspections | $0 | $200 | $1,000 | Regional variance |
Labor hours: 1.5–2.5 hours per square for standard shingles, depending on pitch and complexity.
Reroof Cost by Roof Size: 15, 20, or 25 Squares
The pricing spread for a 15–25 square roof shows how area drives total cost. A typical single-family roof falls in this range, translating to roughly $5,250–$11,000 for asphalt shingles. Smaller homes trend toward the low end; larger roofs push into the average and high ranges.
Assumptions: No major structural repairs, standard 4/12 pitch, and access for a typical dumpster.
Material Choice and Per-Square Price Spread
Material selection directly changes the per-square cost. Asphalt shingles stay in the $350–$800 per square band depending on quality and warranties. Metal, tile, and composite options can lift the per-square price beyond $900 in some markets.
Assumptions: Asphalt composition 25-year to 40-year lifespan; metal panel systems priced per square including install.
Regional Price Variations for Reroofing Per Square
Cost per square tends to be lowest in rural areas and highest in coastal or high-demand urban markets. Typical regional deltas range from -15% to +25% relative to national averages. Region drives labor and disposal costs more than material choice alone.
Assumptions: North-Central vs West Coast labor rates; disposal costs vary by city landfill fees.
Impact of Roof Pitch and Complexity on Price Per Square
Steeper pitches and complex layouts add labor time and safety requirements. A 6/12 pitch or steeper can push per-square labor costs up by 20–40%. Dormers, skylights, and chimney work add estimated per-square charges.
Assumptions: 4–6 roof penetrations; standard flashing details included.
Cost Components That Shape the Quote
A typical reroof quote breaks down into major elements: Materials, Labor, Removal/Disposal, Permits, and Waste Management. Understanding each helps compare bids accurately.
Assumptions: Each square includes underlayment and basic starter strips; no major structural repair costs included in base estimate.
| Cost Component | Typical Range per Square | Notes |
|---|---|---|
| Materials (shingles, underlayment, flashing) | $120–$300 | Quality and warranty impact |
| Labor | $180–$350 | Crew size, region, pitch |
| Removal/Disposal | $50–$120 | Old roof type affects this |
| Permits/Inspections | $0–$1000 | Local rules vary |
| Delivery/Equipment | $20–$50 | Dumpster, lift equipment |
| Warranty/Overhead | $0–$60 | Company policy dependent |
Variables That Most Change the Final Reroof Price
Key drivers include roof area and pitch. A larger home with a 6/12 pitch can add 20–40% to the base price. Another driver is roof complexity, such as multiple dormers or valleys, which adds labor hours and waste handling.
Assumptions: Typical suburban site with standard access; no unusual structural repairs.
Strategies to Lower Reroof Cost Without Compromising Quality
Options to reduce price include choosing mid-range materials, consolidating trips, scheduling in dry months, and avoiding premium upgrades. Lock in a fixed bid when possible to avoid cost creep.
Assumptions: Weather windows align with crew availability; no emergency repairs required.
Three Real-World Quote Examples for Per-Square Pricing
Example A uses asphalt shingles on a 20-square roof with standard pitch and no dormers. Estimated range: $5,400–$9,000 per square total; per-square breakdown shows $180–$340 labor, $120–$250 materials.
Example B covers a 22-square roof with two dormers and a 5/12 pitch, selecting upgraded shingles. Estimated total: $11,000–$15,500; per-square labor higher, materials higher.
Example C involves metal roofing on a 18-square house with complex flashing. Estimated total: $7,000–$12,000; per-square material costs rise with panel system, installation complexity rises labor.
Assumptions: Local permits included where required; disposal fees vary by municipality.
Maintenance Window: When to Re-Roof and How It Affects Price
Scheduling during mild seasons helps avoid rush charges and weather delays. A planned reroof in spring or summer tends to keep quotes stable. Unexpected delays raise costs through extended labor time and potential permit expiration risks.
Assumptions: No wind or hail damage repairs required upfront.
