How to Use This Calculator
Enter your roof details and the calculator estimates your total replacement cost:
- Roof Area or House Size — Enter your roof's surface area in square feet, or let the calculator estimate it from your building footprint and pitch
- Roofing Material — Select from asphalt 3-tab, architectural shingles, metal (standing seam or corrugated), clay tile, concrete tile, slate, or wood shake
- Roof Pitch — Affects labor cost; steep roofs (7/12+) carry a surcharge of 15–40%
- Stories — Second-story and higher work costs more due to equipment and safety requirements
- Region — Labor costs vary significantly by region (Northeast and West Coast are highest)
The output shows low, mid, and high estimate ranges based on national pricing data. These are ballpark figures — always get multiple contractor quotes.
Cost Per Square Foot Reference
Total Cost = (Material Cost/sq ft + Labor/sq ft + Overhead) × Roof Area
+ Steep Slope Surcharge (if pitch > 7/12)
+ Multi-story Surcharge
+ Tear-off Cost (if existing roofing must be removed)
+ Permit Fees
Typical Installed Costs (2026 national average):
3-Tab Asphalt: $4.00 – $6.00 / sq ft
Architectural: $5.00 – $8.00 / sq ft
Metal (corrugated): $7.00 – $12.00 / sq ft
Standing Seam: $12.00 – $22.00 / sq ft
Concrete Tile: $9.00 – $15.00 / sq ft
Clay Tile: $12.00 – $25.00 / sq ft
Slate: $15.00 – $40.00 / sq ft

Frequently Asked Questions
National average for a 2,000 sq ft home: $8,000–$20,000 for architectural shingles. Metal roofing on the same home runs $16,000–$44,000. Costs have increased 20–30% since 2020 due to material and labor inflation.
Most jurisdictions require a permit for a full roof replacement, though some allow re-roofing (overlay) without one. Never skip a required permit — it can cause problems with insurance claims and home sales. A reputable contractor handles permitting as part of their service.
3-tab asphalt shingles are the least expensive option ($4–6/sq ft installed). However, architectural shingles cost only slightly more and last 5–10 years longer, making them usually a better value. Avoid very cheap contractors — the cheapest quote often means corners will be cut.
Insurance covers sudden damage (storm, hail, falling trees) but not wear-and-tear or age-related deterioration. If your roof is over 20 years old, many insurers pay only ACV (depreciated value) rather than full replacement cost. Review your policy carefully.
3-tab shingles: replace at 20–25 years. Architectural shingles: 25–35 years. Metal: 40–70 years. Tile: 50+ years. Slate: 75–100+ years. Age is just one factor — regular inspection matters more. A 15-year-old roof in poor condition may need replacement before a well-maintained 25-year-old one.
