Frequently Asked Questions

How much does a roof replacement cost in 2026?

Roof replacement costs $4–$30 per square foot in 2026 depending on material. Asphalt shingles average $8,000–$12,000 for a 2,000 sq ft roof. Metal roofing runs $16,000–$30,000. Tile and slate cost $20,000–$60,000+ for the same size.

How long does a roof last?

Asphalt shingles last 20–30 years. Architectural shingles last 30–40 years. Metal roofs last 40–70 years. Clay or concrete tile lasts 50–100 years. Slate can last 100+ years. Consider longevity when comparing costs.

How many layers of shingles can I have?

Most building codes allow a maximum of 2 layers of asphalt shingles. Adding a second layer avoids tear-off costs ($1,000–$2,000) but adds weight and is not recommended for aging decks. A full tear-off is always better long-term.

What factors affect roof replacement cost most?

The biggest factors are roof size (measured in squares = 100 sq ft), pitch/steepness (steep roofs add 20–40%), number of layers to remove, decking condition, number of penetrations (chimneys, skylights), and your geographic location.

Should I repair or replace my roof?

If your roof is under 15 years old and less than 30% of shingles are damaged, repair is usually cost-effective. If the roof is over 20 years old, has widespread damage, or shows signs of structural issues, full replacement is the better investment.
