Winston-Salem’s commercial buildings take a beating. Between the summer humidity that never seems to quit, UV exposure that degrades roofing materials faster than you’d think, and those sudden afternoon storms that roll through the Piedmont Triad, your flat roof has to perform year-round. We just finished a TPO roofing project in nearby High Point that shows exactly what happens when a commercial roof reaches the end of its life — and how TPO Roofing services can give you a watertight, energy-efficient solution that’ll last decades. If you’re managing a building in Winston-Salem and wondering whether your roof needs attention, here’s what we found and what we did about it.
What We Found: Rotten Edge Wood and Failed TPO Membrane
When we climbed onto this High Point commercial building, the problems were obvious. The perimeter edge wood was completely rotten. Water had been working its way under the old TPO membrane for years, and once it reached the wood substrate at the edges, decay set in fast.
The membrane itself had reached the end of its service life. We’re talking about exposed areas where the TPO had deteriorated, leaving the roof deck vulnerable. The edge conditions were particularly bad — this is where most flat roof failures start, and this one was no exception.
Here’s what makes this relevant for commercial roofing in Winston-Salem: your buildings face the same climate conditions. High heat, high humidity, and intense UV exposure all year. TPO is designed to handle these conditions, but only if it’s installed correctly and maintained properly. When it fails, water finds the weak spots fast.
Why TPO Roofing Winston-Salem NC Business Owners Choose It
TPO has become the go-to membrane for commercial flat roofs across the Piedmont for good reasons. The white reflective surface throws heat back into the sky instead of letting it soak into your building. In a Winston-Salem summer, that matters.
We’ve installed TPO on warehouses, office buildings, retail centers, and industrial facilities throughout the Triad. It holds up to our weather patterns better than modified bitumen, costs less to maintain than EPDM, and when it’s heat-welded properly, those seams are stronger than the membrane itself.
The National Roofing Contractors Association has documented TPO’s performance across different climate zones, and the Southeast results speak for themselves. This membrane was engineered for heat and humidity.
But here’s the thing: TPO is only as good as the installation. We see botched TPO jobs all the time — improper fastener spacing, cold welds that’ll fail in three years, inadequate edge details that let water creep under the membrane. The material itself is excellent. The execution is what separates a roof that lasts from one that becomes your problem.
The TPO Roofing Winston-Salem NC Process: What We Actually Did
First, we tore off the old failed TPO system. No shortcuts. When you’ve got rotten wood substrate, you have to expose it and fix it right.
We replaced all the deteriorated edge wood. This is non-negotiable. You can’t fasten new membrane to rotten substrate and expect it to hold. We installed solid, treated wood blocking around the entire perimeter.
Then we installed the new TPO membrane with fully adhered perimeter details. This is critical for wind uplift resistance. In Winston-Salem, you get those sudden storm cells that can generate serious wind. A mechanically attached system with proper edge adhesion is your insurance policy against blow-offs.
We built new HVAC curbs with proper flashing details. Every penetration through a flat roof is a potential leak point. The curbs have to be tall enough to keep water away from the membrane-to-curb transition, and the TPO has to be heat-welded to the curb flashing in a way that creates a continuous waterproof barrier.
Heat welding is where TPO really shines. We use hot-air welders that melt the membrane seams together at the molecular level. When it cools, you don’t have a seam anymore — you have a single continuous sheet of TPO. That’s why TPO outlasts glued or taped seam systems.
We staged materials carefully to avoid damaging the new membrane during installation. TPO is tough, but you don’t walk all over it with sharp tools or drop HVAC equipment on it. Professional installation means protecting your investment from day one.
Signs Your Winston-Salem Building Needs TPO Roofing Replacement
Here’s what to watch for. If you’re seeing any of these conditions, call us before small problems become building damage:
- Water stains on interior ceilings or walls — this means the roof has been leaking for a while
- Ponding water that sits more than 48 hours after rain — flat roofs should drain
- Visible membrane deterioration, especially at seams and edges
- HVAC curb flashing that’s cracked, separated, or patched with tar
- Edge metal that’s pulling away or showing rust
- Blisters or bubbles in the membrane surface — trapped moisture expanding in the heat
- Exposed substrate anywhere — if you can see what’s under the membrane, water can reach it
- Your roof is over 20 years old and you’re not sure when it was last inspected
Don’t wait until you can see daylight through the deck from inside. By the time you’re at that point, the roof has been leaking for years and you’ve got structural damage to deal with.
We recommend annual roof inspections at minimum for all commercial flat roofs. If you’ve got HVAC units on the roof or trees nearby, twice a year is smarter. Small repairs caught early cost hundreds. Major structural work costs tens of thousands.

Joe Yutzy started Sunny Sky Roofing LLC because he got tired of watching building owners get sold the wrong solution by contractors who didn’t understand commercial roofing systems. We’re not a residential crew that dabbles in commercial work. We’re commercial roofing specialists who work throughout the Piedmont Triad.
We know Winston-Salem’s building stock. We’ve worked on everything from old tobacco warehouses converted to office space to modern retail centers on Peters Creek Parkway. Different buildings need different approaches, and we’ve got the experience to recommend what actually makes sense for your situation.
When we say we’re going to install TPO with fully adhered perimeter details, we show up with the materials and crew to do exactly that. We don’t change the scope halfway through or surprise you with upcharges for work that should’ve been included from the start.
Our crews are trained on proper TPO installation techniques. Heat welding requires skill and the right equipment. We invest in both. We’re not learning on your roof.
We’ll tell you the truth about what your roof needs. Sometimes that’s a full replacement like this High Point project. Sometimes it’s targeted repairs or a coating system that’ll buy you another decade. We make our recommendations based on what’s actually happening on your roof, not what generates the biggest invoice.
You’ll get straight answers about timeline, materials, and what to expect during construction. Commercial roofing disrupts your business — we get that. We work to minimize that disruption while still doing the job right.
Frequently Asked Questions About TPO Roofing in Winston-Salem
How long does a TPO roof last in North Carolina’s climate?
A properly installed TPO membrane should give you 20 to 30 years in our climate, assuming you maintain it with annual inspections and address small issues before they become big ones. The heat-welded seams are the key to longevity — they don’t degrade like adhesive or tape-based systems. UV exposure is actually where TPO excels compared to other single-ply membranes. That white reflective surface is engineered to handle intense sun without breaking down.
Can you install TPO over my existing roof, or do you have to tear off?
It depends on what’s underneath and what condition it’s in. If you’ve got one layer of old membrane and the substrate is sound, we can sometimes install TPO over it. But if there’s moisture in the existing system, rotten wood, or multiple old layers, tear-off is the only option that makes sense. We don’t cover up problems — we fix them. On this High Point project, the rotten edge wood meant tear-off was required. We need a solid base to fasten to.
What kind of maintenance does a TPO roof need?
Annual inspections at minimum. We walk the roof, check all the penetration flashings, look for any seam issues, clear drains, and catch small problems early. If you’ve got HVAC units up there, we recommend twice-a-year inspections — spring and fall. Keep the drains clear and address ponding water issues promptly. Don’t let maintenance crews patch problems with tar or sealant that’ll fail in six months. Call us for proper repairs using compatible TPO materials and heat-welded seams.
How does TPO handle Winston-Salem’s summer heat and humidity?
Better than just about any other commercial roofing membrane. The white reflective surface can stay 50 degrees cooler than a dark roof, which means your HVAC system doesn’t work as hard. TPO is chemically resistant to moisture and mold growth, so our humid summers don’t degrade it the way they can with organic materials. The membrane is flexible enough to expand and contract with temperature changes without cracking. It’s honestly one of the best-engineered solutions for our climate.
