A standard asphalt shingle roof for a typical home runs $8,000-$15,000. Metal roofing costs $15,000-$30,000+. Cedar shake and slate are $20,000-$40,000+. Price depends on roof size, pitch, and material.

Signs include missing or curling shingles, granules in gutters, water stains on ceilings, daylight through attic boards, and a roof older than 20-25 years. Get a professional inspection if you see any of these.

Asphalt shingles last 20-30 years, metal roofing 40-70 years, cedar shake 30-50 years, and slate 75-100+ years. Canadian weather (freeze-thaw cycles, ice, heavy snow) can shorten lifespan.

Insurance typically covers sudden damage (storms, fallen trees, hail) but not wear and tear or age-related deterioration. Document damage with photos and file a claim quickly. Your roofer can provide a damage report for your insurer.

Requirements vary by province. In Ontario, roofers working on steep slope need to be registered. Always verify liability insurance and WSIB coverage. Check for manufacturer certifications (GAF, CertainTeed, IKO).

Late spring through early fall is ideal. Shingles need warm temperatures to seal properly. Emergency repairs can be done year-round. Book spring replacements in winter for better pricing and availability.
