Browse the roof systems below to compare membrane options by condition, drainage, and warranty needs.
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.

Fleeceback TPO
A fleece-backed TPO bonds to the substrate with adhesive and resists punctures better than standard membrane, a sturdy pick for DC roofs that take regular service traffic.
Open details
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
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
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
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
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
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
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
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
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
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.
