Roofing costs in the United States
US roofers charge $3.50–$7.00 per square foot installed for asphalt shingles, the most common material. A full replacement on a 2,000 sq ft roof typically costs $8,000–$15,000. Metal roofing runs $12,000–$25,000+. Prices are highest in the Northeast and West Coast, lowest in the South and Midwest.
After storm damage, your homeowner's insurance may cover some or all of the replacement cost minus your deductible. Always get your own independent estimate — don't rely solely on the insurance adjuster's assessment. Be cautious of storm-chasing roofing companies that appear after severe weather.
What affects the cost?
- Roof size — measured in "squares" (100 sq ft each); a typical home is 20–35 squares
- Material — asphalt shingles are cheapest ($3–$5/sq ft installed), metal is mid-range ($7–$14), tile and slate are premium ($10–$25+)
- Roof pitch/steepness — steep roofs require extra safety equipment and take longer
- Layers to remove — tearing off old layers before installing new ones adds $1,000–$3,000
- Structural damage — rotted decking or damaged rafters must be repaired first
- Permits and inspections — most jurisdictions require permits for full replacements
- Season — late spring through early fall is peak roofing season with higher prices
How to save on roofing costs
- Schedule in the off-season — late fall and winter may bring 10–15% lower prices
- Get 3–5 quotes — roofing estimates vary more than most trades
- Choose asphalt over premium materials — modern architectural shingles last 25–30 years at half the cost of tile
- Bundle with gutters — adding gutters during a roof replacement is cheaper than a separate project
- Check insurance coverage — storm and hail damage may be covered

Frequently asked questions
How much does a new roof cost?
A new asphalt shingle roof runs $5,000–$15,000 in the US for an average 2,000 sq ft home, or $4–$8 per square foot installed. Architectural shingles add 20–30%. Metal roofs cost $10,000–$25,000+ but last 50+ years vs 20–25 for shingles. Tile and slate run $20,000–$50,000+.
Will insurance cover a new roof?
Sometimes. Insurance covers roof damage from sudden events: hail, wind, fallen trees, fire. It does NOT cover wear-and-tear, age, or maintenance issues. File a claim if storm damage occurred. The insurer sends an adjuster; you should also have an independent roofer present to advocate for full coverage.
How long does a roof last?
Asphalt shingles: 20–25 years. Architectural shingles: 30 years. Metal: 40–70 years. Tile/slate: 50–100 years. Wood shake: 25–30 years. Lifespan depends heavily on climate (heat and freeze cycles age roofs faster) and quality of installation. Annual inspections extend useful life.
Should I repair or replace my roof?
Repair if: damage is localized, the roof is under 15 years old, less than 30% of shingles need replacement. Replace if: 20+ years old, multiple leaks, widespread granule loss, sagging, daylight visible through the attic. Repair-vs-replace decisions over $5,000 should always include a second opinion.
