How much does it cost to replace a roof?

The national average for a full roof replacement on a 2,000 sq ft home is $8,000–$20,000. Asphalt shingles average $4.00–$7.00 per sq ft installed. Metal roofing runs $8–$20 per sq ft installed. Tile and slate run $10–$30+ per sq ft. Factors include roof size, pitch, material, tear-off, and regional labor costs.

What is included in a roof replacement cost?

A full replacement cost includes: tear-off and disposal of old roofing, new decking if needed, ice and water shield, underlayment, roofing material (shingles/metal/tile), ridge cap, drip edge, flashing, ventilation, labor, and cleanup. Permits may add $100–$500 depending on jurisdiction.

How do I get an accurate roof replacement quote?

Get at least 3 written bids from licensed, insured contractors. Each bid should break down material costs, labor, tear-off, disposal, and permit fees separately. Ask specifically about manufacturer warranty requirements. Use this calculator to establish a baseline before meeting with contractors.

Does roof pitch affect replacement cost?

Yes, significantly. A steep roof (7/12 or greater) costs 15–40% more to replace than a walkable roof because it requires safety equipment, takes longer to work on, and uses more material per square foot of floor area. Most contractors apply a steep slope surcharge above 7/12 pitch.

How long does a roof replacement take?

A typical residential roof replacement takes 1–3 days. A small simple roof can be done in one day. Large complex roofs with multiple levels or steep pitches may take 3–5 days. Weather delays can extend the timeline. Most established contractors schedule completion within 1–2 weeks of material delivery.

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.
