[ Modified Bitumen SBS SBS modified bitumen stays rubbery in the cold, an advantage through the region's freeze-thaw cycling, and can be cold-applied where an open flame is not allowed on an occupied building.

Open details](https://commercialrooferswashington.com/roof-systems/fleeceback-tpo)[ Built-Up Asphalt Layered asphalt-and-felt roofs bring proven redundancy to heavy institutional decks around the capital, and their thick build tolerates foot traffic well, though they add weight a deck must be checked for. Open details](https://commercialrooferswashington.com/roof-systems/built-up-asphalt)[ KEE Roof Systems KEE-based single-ply keeps its plasticizers far longer than ordinary PVC, so it stays flexible and crack-resistant through years of Washington sun and chemical exposure. Open details](https://commercialrooferswashington.com/roof-systems/kee-roof-systems)[ White EPDM White EPDM marries rubber's cold-weather flexibility with a reflective surface, cutting summer heat gain while still flexing through the region's freeze-thaw swings on flat commercial roofs. Open details](https://commercialrooferswashington.com/roof-systems/white-epdm)[ Modified Bitumen APP APP modified bitumen is torch-applied and forms a tough, UV-stable cap, suiting flat DC roofs that need a rugged surface able to handle maintenance foot traffic. Open details](https://commercialrooferswashington.com/roof-systems/modified-bitumen-app)[ TPO 80 Mil Eighty-mil TPO adds thickness for roofs that see heavy foot traffic and hail, a tougher choice for DC-area buildings where rooftop service is constant and the membrane needs extra reserve. Open details](https://commercialrooferswashington.com/roof-systems/tpo-80-mil)[ Silicone Roof Coating A fluid-applied silicone coating renews a weathered roof in place, sealing seams and shrugging off the standing water that lingers on flat DMV roofs after a storm. Open details](https://commercialrooferswashington.com/roof-systems/silicone-roof-coating)[ Spray Polyurethane Foam Where a flat DC roof is structurally fine but under-insulated and pooling, sprayed polyurethane foam is a retrofit that adds R-value and re-pitches drainage at once, then takes a silicone or acrylic topcoat to carry the UV and foot traffic. Open details](https://commercialrooferswashington.com/roof-systems/spray-polyurethane-foam)[ PVC Roof Systems Hot-air-welded PVC creates monolithic seams that resist ponding water and rooftop grease, a dependable system for the restaurant and lab roofs common across the District. Open details](https://commercialrooferswashington.com/roof-systems/pvc-roof-systems)[ Black EPDM Black EPDM rubber flexes through the DMV's freeze-thaw winters and ages predictably, making it a budget-friendly membrane where reflectivity is not the priority. Seam quality decides its real lifespan. Open details](https://commercialrooferswashington.com/roof-systems/black-epdm)[ TPO 60 Mil Sixty-mil TPO is the everyday workhorse white membrane for DMV commercial roofs, balancing puncture resistance and cost while its welded seams and reflective surface fight the heat of a Washington summer.
