Commercial roofing covers everything a business owner or property manager deals with above the ceiling tiles: flat and low-slope roof installs, TPO, EPDM, and modified bitumen systems, metal roof retrofits, recoating and restoration work, storm and hail damage repair, and the ongoing inspections that keep a warranty valid. It's a different trade than residential shingle work. Crews need experience with large membrane systems, rooftop HVAC penetrations, drainage design, and the safety and insurance requirements that come with commercial job sites. In Newnan, that pool of specialized contractors sits alongside general roofers, so it's worth confirming a company actually does commercial work day to day, not just as a side job.
What to look for before you hire
- Commercial-specific experience: ask for recent flat-roof or low-slope jobs, not just steep residential ones.
- Proper licensing and insurance: general liability and workers' comp matter more on a commercial roof, where crews are working over occupied space and expensive equipment.
- Manufacturer certification: installers certified by TPO or EPDM manufacturers can usually offer stronger, longer material warranties.
- A written scope and inspection process: a contractor who documents roof condition with photos before and after work, and who explains drainage and flashing details, is less likely to leave you with a surprise leak.
- References from similar properties: a retail strip mall roof and a warehouse roof aren't the same job; ask for examples that match your building type.
