How to Verify a Roofing Contractor's Credentials

Contractor verification protects homeowners from unqualified operators, fraudulent businesses, and substandard work. An unverified contractor may lack proper insurance (leaving you liable for injuries on your property), may not hold valid licenses (meaning no regulatory oversight), and may not carry adequate bonding (giving you no financial recourse if the project fails). Verification is especially critical for roofing because poor workmanship can lead to water damage, structural issues, and tens of thousands in additional repair costs.

A licensed contractor has met their state's minimum requirements to legally perform roofing work. Requirements vary by state but typically include passing a trade exam demonstrating knowledge of building codes and roofing practices, meeting minimum experience requirements (usually 2-4 years), providing proof of insurance coverage, paying licensing fees and completing continuing education, and passing a background check in some states. Note that some states (like Texas) do not require state-level roofing licenses, making other verification steps even more important.

Request a Certificate of Insurance (COI) directly from the contractor. The COI should list their insurance company, policy numbers, coverage amounts, and effective dates. Critically, call the insurance company directly to confirm the policy is current and in good standing — certificates can be forged. Verify both general liability coverage (minimum $500,000, ideally $1 million) and workers' compensation insurance. Ask to be named as an 'additional insured' on the policy for your project.

Manufacturer certifications (like GAF Master Elite, CertainTeed SELECT ShingleMaster, or Owens Corning Preferred) indicate that a contractor has met specific training, experience, and business standards set by roofing material manufacturers. These certifications matter because they typically enable enhanced warranty coverage (up to 50-year or lifetime warranties), demonstrate ongoing professional training, require minimum insurance and licensing, and are awarded to only a small percentage of contractors (e.g., GAF Master Elite is limited to the top 2% of contractors nationwide).

RoofingPros provides verification badges for contractors whose licensing, insurance, and bonding status have been confirmed. However, our comprehensive directory includes all known roofing contractors, including those whose credentials have not yet been verified. Contractors can claim their profile and submit credentials for verification. We encourage homeowners to look for verified badges and to independently verify credentials for any contractor they plan to hire, regardless of directory listing status.
