Flat and commercial roofing covers a different skill set than standard residential shingle work. Torrington's mix of retail strips, warehouses, and older commercial buildings mostly relies on membrane systems: TPO, EPDM rubber, and modified bitumen, along with built-up roofing on some older structures. The work includes new installs, full tear-off replacements, section repairs, and the seam and flashing maintenance that flat roofs need more often than pitched ones because water has nowhere to run off quickly.
Before hiring, ask whether the contractor is licensed and insured for commercial work specifically, since that liability coverage differs from residential jobs. Get a written scope that names the membrane type, thickness, fastening method, and warranty terms (manufacturer warranty versus workmanship warranty are not the same thing). Ask how they handle drainage and ponding water, a common failure point on flat roofs, and whether they inspect the deck and insulation before quoting rather than just the surface membrane.
