Commercial roofing covers the flat and low-slope systems you find on strip malls, warehouses, offices, and light-industrial buildings around Thomasville: TPO and EPDM membranes, modified bitumen, built-up (tar and gravel) roofs, and metal retrofits. It's a different trade than residential shingle work. Crews need experience with large-scale membrane welding, roof drainage and ponding-water fixes, insulation and coverboard installation, and coordination around HVAC units, vents, and other rooftop equipment that a house roof never has to deal with. Jobs also tend to run on tighter timelines to limit disruption to a business, and often require work to be scheduled around tenants or operating hours.
What to look for in a commercial roofer
Start with licensing and insurance, including general liability and workers' comp certificates you can actually verify, since a fall on a flat roof is a serious liability if the crew isn't covered. Ask whether the manufacturer certifies them to install the specific membrane system you're considering (TPO, EPDM, or modified bitumen), because that certification is usually what makes the material warranty valid. Get a written scope that separates tear-off, insulation, membrane, flashing, and drainage work, not just a lump sum. A roofer who inspects the deck and drainage before quoting, rather than pricing off a satellite photo, is a good sign. Also ask about their process for keeping the building watertight and operational during the work, and who handles debris and disposal.
