Commercial roofing covers a different set of problems than a residential reroof. Atlanta's contractors in this category handle low-slope and flat systems on warehouses, retail strips, office parks, and multi-family buildings: TPO and PVC single-ply membranes, modified bitumen, EPDM, built-up (tar and gravel) roofs, and metal panel systems on larger spans. The work ranges from full tear-offs and re-covers to preventive maintenance programs, coating applications that extend the life of an existing membrane, and emergency leak response after storms. We're tracking 97 businesses in the metro area that do this kind of work.
Because a commercial roof failure can shut down a business or damage inventory, the stakes are higher than on a house. A buyer should look for contractors who carry manufacturer certifications (GAF, Firestone/Elevate, Carlisle, etc.), since those certifications often come with better warranty terms and mean the crew has been trained on that specific system. Ask for proof of commercial general liability and workers' comp insurance, references from similar-sized projects, and a written scope that specifies membrane thickness, insulation R-value, drainage fixes, and flashing details, not just square footage and price.
Our scoring weighs licensing, insurance, verified customer feedback, responsiveness, and how consistently a company shows up across multiple review sources, not just star averages.
