How to Find & Vet a Licensed Roofing Contractor in Detroit, MI

Michigan does not require a state-level roofing license, but roofers operating in Detroit must hold a valid contractor's license from the City of Detroit or comply with local building codes. Before hiring, ask for the contractor's business license number and verify it through the Michigan Department of Licensing and Regulatory Affairs (LARA) online portal. Request proof of registration with the Better Business Bureau (BBB) and check their rating—Detroit contractors should maintain at least an A rating. Never hire someone who cannot or will not provide license documentation. Legitimate contractors keep this information readily available because they have nothing to hide.

Michigan law requires roofing contractors to carry general liability insurance (minimum $1 million recommended) and workers' compensation insurance. Before any work begins, ask for a Certificate of Insurance naming you as an additional insured—this protects you if a worker is injured on your property. Call the insurance company directly to verify the policy is active; do not rely on photocopied certificates alone. Roofing work on homes with mortgages may also require bonding, especially for larger projects over $5,000. If a contractor refuses to provide proof of insurance or bonding, walk away immediately—this is a critical red flag in Detroit's market.

Obtain at least three independent quotes from different contractors in the Detroit area to establish a realistic price range. Roof replacement typically costs $6,500–$12,000 for a standard single-family home (depending on material, pitch, and size), while repairs average $300–$1,500. When comparing quotes, ensure they specify the same materials, warranty terms, timeline, and labor scope. A quote significantly below market rate often signals cut corners or hidden costs later. Request itemized estimates that break down materials, labor, permits, and cleanup. Cheaper isn't better in roofing—you're protecting a major asset, and quality workmanship extends your roof's lifespan by years.

Ask each contractor for at least three references from Detroit-area homeowners with similar roof types or repair needs. Contact these references directly and ask about timeline adherence, cleanliness, communication, and whether the work held up over time. Check online reviews on Google, Yelp, and the BBB, but weigh recent reviews more heavily—a contractor's reputation can change. Request to see photos of completed projects or, better yet, ask if you can drive by a finished job in your neighborhood. Local experience matters: a roofer familiar with Detroit winters, ice dams, and typical residential roof styles will anticipate problems and deliver better results than someone new to the area.

Do not hire contractors who demand full payment upfront, request cash only, or pressure you to sign before providing a written estimate. Avoid anyone unwilling to provide references, license details, or proof of insurance—these are standard business practices, and refusal suggests hidden problems. Be wary of door-to-door roofers or those who claim to have "leftover materials" from another job and can offer a discount. After severe weather (hail, high winds), scammers flood Detroit neighborhoods offering free inspections and inflated damage claims—always verify claims through your insurance company first. Never hire someone who doesn't pull permits; unpermitted work voids warranties, creates liability issues, and can fail home inspections. Finally, avoid contractors with multiple outstanding complaints in the BBB database or unresolved legal judgments.
