What to Know Before Hiring a Roofing Contractor

Signs Your Roof Needs Repair or Replacement

Most homeowners don't think about their roof until something goes wrong. But catching problems early saves thousands of dollars. Watch for these warning signs: granules collecting in gutters after rain, shingles that curl, crack, or are missing entirely, water stains on ceilings or attic walls, sagging sections along the roofline, and daylight visible through the attic. Any one of these signals it's time for a professional inspection.

Storm damage — hail, high winds, falling branches — is the leading cause of insurance claims for roofing work in the United States. After any major weather event, a free inspection from a licensed local contractor documents damage before insurance claim windows close. Most carriers require claims within 12 months of the storm date.

How Much Does a Roof Replacement Cost?

Roofing costs vary significantly based on roof size, pitch, material choice, tear-off requirements, and local labor rates. A typical single-family home runs $8,000–$22,000 for an architectural asphalt shingle replacement — the most common choice for cost-conscious homeowners. Metal roofing runs $15,000–$35,000 but lasts 40–50 years. Tile and slate are premium options starting at $20,000 and higher, but add significant curb appeal and longevity in the right climates.

Getting multiple quotes from licensed local contractors is the single best way to understand fair pricing in your specific market. Labor costs vary widely by region — the same job can cost 30–40% more in a high cost-of-living area than in a rural market. Comparing at least three written estimates is standard practice before hiring.

How to Choose a Roofing Contractor

Licensing requirements differ by state, but in every market, you should verify the contractor holds an active license through your state's contractor licensing board before any work begins. Ask for proof of general liability insurance and workers' compensation coverage — without it, you can be liable for injuries that occur on your property during the project.

Look for contractors who pull permits for all jobs. Permit-pulling is required by law in most jurisdictions and ensures the work gets a final inspection by a city or county building official. Contractors who skip permits are a red flag: unpermitted work voids your homeowner's insurance coverage, creates disclosure liability when you sell, and may require expensive removal and replacement to bring into compliance.

A written contract protects both parties. Before signing, confirm the scope of work, materials specified by manufacturer name and product line, tear-off and disposal details, permit responsibility, payment schedule, warranty terms (manufacturer's warranty on materials and contractor's warranty on labor), and the project start and completion dates.

Understanding Roof Warranties

Roofing warranties come in two forms: manufacturer warranties covering material defects, and contractor workmanship warranties covering installation quality. A typical architectural shingle carries a 25–30 year manufacturer warranty, but this only applies if the product is installed by a contractor certified by the manufacturer. Many homeowners are surprised to learn their material warranty is void because the installer wasn't certified. Always ask your contractor to confirm their certification status with the manufacturer of your chosen shingle.

Workmanship warranties from contractors typically run 2–10 years. The quality of this warranty reflects the contractor's confidence in their work. A contractor offering only a 1-year workmanship warranty on a new roof installation is worth scrutinizing — most reputable contractors offer at least 5 years.
