Commercial Roofing in Washington D.C. & the DMV — TPO, EPDM & Modified Bitumen
Commercial, mixed-use, and multi-family buildings across the DMV run on flat and low-slope roofs, and those systems succeed or fail on detailing rather than the membrane brand on the invoice. We install, replace, and maintain single-ply TPO and EPDM membranes and modified-bitumen systems for property owners and managers across Washington D.C., Arlington, Alexandria, Fairfax County, and Montgomery County — with the seam quality, drainage, and flashing that decide whether a flat roof reaches its rated life.
Each system has a place. TPO is a reflective white single-ply that is popular for energy performance, with heat-welded seams that are stronger than the membrane itself and a typical life of 20–30 years at roughly $5.50–$7.50 per square foot. EPDM is a proven black rubber membrane with a long track record, commonly 25–30 years and often a touch less per square foot. Modified bitumen is a multi-ply asphaltic system, dependable but generally shorter-lived at 15–20 years. We scope the choice to your building's roof traffic, drainage, insulation, and budget, and we build in tapered insulation so water actually runs to the drains instead of ponding — ponding water is the single most common reason a flat roof fails early.
For owners and managers, a roof is an asset to be maintained, not just a thing that leaks. We run preventative maintenance and leak-response programs — scheduled inspections, seam and flashing checks, drain clearing, and fast response when something does go wrong — that extend membrane life and keep a small problem from turning into a tenant-facing one and a much larger bill. Every visit is documented for your capital-planning records, so you are budgeting from data, not guesswork.
