Commercial roofing covers the installation, repair, and replacement of roof systems on office buildings, warehouses, retail centers, and multi-family properties. Around Atlanta that mostly means low-slope systems: TPO and PVC single-ply membranes, modified bitumen, built-up (tar and gravel) roofs, and increasingly spray polyurethane foam on older flat-roof buildings. Metal panel roofing shows up on warehouses and industrial buildings, especially along the I-285 corridor and in the Fulton Industrial area. This category lists 122 contractors in the metro area who work on commercial rather than residential structures.
Commercial jobs run differently from a house re-roof. There's usually a roof survey or core sample before bidding, work has to happen around tenants and business hours, and material specs are often tied to insurance requirements or a manufacturer's warranty program. When you're vetting a contractor, check that they carry commercial general liability and workers' comp at levels appropriate for the building size, ask whether they're a certified installer for the membrane brand they're proposing (GAF, Carlisle, Firestone/Elevate, etc.), and get a written scope that covers tear-off, insulation, drainage tapering, and flashing detail, not just "new roof." Georgia's summer heat and afternoon storms also make proper ventilation and drainage design worth asking about directly.
Our scoring weighs licensing and insurance status, how a company responds to inquiries, review patterns over time, and how long they've been operating commercially versus residentially.
