Where flat roofs leak in Winston-Salem
We’re based on Reynolda Road, just south of Wake Forest University, so a Winston-Salem flat-roof call is a short drive for us — not a regional dispatch. That matters, because low-slope leaks tend to get worse fast and we can usually get a crew out within the week.
The flat-roof calls in this city cluster in a few predictable places. In the Sherwood Forest and Forest Hills ranches built in the 1960s and 70s, we see genuine mid-century modern homes with flat or near-flat main roofs — sections that were never meant for shingles and have been patched for decades. Across Buena Vista, West End, and Ardmore, the problem is usually a porch roof or a sunroom addition over an older brick home: someone laid shingles on a slope under 2:12, and it has leaked at the wall flashing every hard rain since. And out toward the newer construction in Clemmons and Lewisville, it’s the 1990s and 2000s sunroom and garage additions reaching the end of any patch’s usefulness all at once.
The right system for the slope
Asphalt shingles need at least a 2:12 pitch to shed water. Below that, they hold water instead of draining it, and they will leak. The fix isn’t a better shingle — it’s the correct low-slope system:
- TPO membrane — our most common choice. A white, heat-welded single-ply that reflects heat (a real benefit on a south-facing Ardmore porch that bakes all summer) with mechanically fused seams that don’t open up as the structure moves. We use it on most residential flat sections and nearly all commercial work.
- EPDM rubber — proven black single-ply, ideal for re-roofs over existing EPDM and for sections shaded by Winston-Salem’s heavy tree canopy, where the dark color won’t drive heat into the room below.
- Modified bitumen — a torch-down or self-adhered membrane we install on smaller porch and bay-window roofs under 400 square feet, where a full TPO install isn’t justified.
- Silicone restoration coatings — if your membrane is aging but not yet failing, a coating can buy 10–15 more years at a fraction of replacement cost. We’ll tell you honestly whether your roof is a candidate.
Two questions before we quote a scope
We don’t recommend a fix until we know two things. First: is the decking wet? Once water reaches the substrate or insulation, capping it with new membrane just traps the moisture. We do a moisture survey or test cuts before committing. Second: how many leaks? One leak on an 18-year-old TPO roof is a repair. Five leaks in different spots means the system is done and patching is throwing good money after bad. You’ll get the real answer, not the one that maximizes our invoice.
Commercial low-slope across the city
Most of our Winston-Salem work is residential, but we’ve installed and maintained commercial flat roofs all over town — the warehouses and office buildings along Stratford Road and University Parkway, and small retail near the Innovation Quarter. We’re Carlisle SynTec authorized for commercial single-ply, with manufacturer system warranties up to 30 years and a dedicated commercial crew that isn’t learning low-slope on your building. For occupied properties, we coordinate site visits around tenant operations.
