How to Choose the Best Commercial Roofing Company in Fort Worth
A practical, no-nonsense guide to vetting a commercial roofer — what certifications matter, what warranties to demand, and the seven red flags that should end the conversation.
The five certifications that actually matter
Manufacturer certification is the strongest signal of installer quality — look for GAF Master Select, Carlisle ESA, Firestone Red Shield, Versico VIP, or Johns Manville Peak Advantage. These programs require rigorous training and audit each install. Without one, you cannot get the manufacturer’s full 20-30 year NDL warranty.
Insurance minimums for commercial work
- General liability: $2M minimum
- Workers’ comp: on every employee
- Umbrella policy: $5M+ for larger projects
- Bond capacity should be listed on request
Seven red flags
Any of these should end the conversation: (1) no manufacturer certification, (2) reluctance to provide COI before contract, (3) door-knocking after a hail event, (4) demands for full payment upfront, (5) verbal-only warranty terms, (6) no drone or written inspection report, (7) refuses to name their crew leads.
