If you’re managing a commercial building in Thomasville, Archdale, or anywhere in the Triad, you’ve probably heard about TPO roofing. It’s everywhere now. But hearing about it and understanding what actually goes into a quality installation are two different things. We just wrapped up a complete TPO roofing Thomasville NC area project in nearby High Point that taught us — again — why the details matter so much on these jobs.
This wasn’t a simple reroof. We dealt with rotten decking, outdated HVAC curbs, and old ventilation equipment that needed to come off before we could even start the real work. The owner wanted it done right, and that meant addressing problems that had been building up for years.
What We Found When We Started the TPO Roofing in Thomasville NC Area
The first step on any job is material staging. We get everything delivered to the site, stack it out, and count through every roll of membrane, every bag of fasteners, every piece of flashing. Why? Because once we start tearing off the old roof, we need to cover everything back up that same day. You don’t leave a commercial building exposed overnight. Ever.
On this High Point project, we found exactly what we expected to find on a building that had been neglected for too long. The fiber board decking was deteriorated in multiple areas. Some spots were completely rotted through. The edge wood where the drip edge fastened was falling apart. We also identified several old ventilation fans, chimney pipes, and one old AC unit that the owner wanted removed.
The existing small AC units had sunk down into the insulation from years of vibration. That’s what happens when curbs aren’t tall enough or when the decking underneath isn’t rigid enough to support the weight and movement.
Why This Matters for Commercial Building Owners in Thomasville NC and Beyond
Here’s what most building owners don’t realize: the membrane is only part of the roofing system. The decking underneath has to be solid. The curbs around your HVAC units have to be the right height and properly sealed. The edge details have to be done correctly or water finds its way in.
When we see fiber board that’s deteriorated, we don’t patch around it. We replace it with ISO board, which is far more rigid and holds up better when water does find its way through. And water always finds its way through eventually — that’s why annual roof inspections matter so much.
This project showed us why you can’t cut corners on the prep work. If we had just laid new TPO over rotten decking and called it done, that roof would’ve failed within a few years. The owner would’ve been out the cost of the membrane, the labor, and he’d still have a failing roof.
The Process: How We Installed This TPO Roof
We tackled this job with a crew of five technicians over eight days. That timeline included the tearoff, all the wood replacement, the new curb installations, and the full TPO installation with details.
Here’s how it went down:
Day One: Material delivery and staging. We verified we had everything we needed before touching the existing roof.
Tearoff and Assessment: We removed the old roofing material in sections, exposing the decking underneath. That’s when we documented all the rotten fiber board and edge wood. We also coordinated with the owner to remove the equipment he wanted gone.
Decking Replacement: Every piece of bad fiber board came out. We replaced it with ISO board. All the rotten edge wood got replaced with new lumber. Where we removed the old units, we patched the holes with plywood to reinforce those areas.
New Curbs: We installed new curbs under the small AC units to lift them up off the roof surface. This prevents them from sinking into the insulation and keeps the weight distributed properly.
TPO Installation: We rolled out the TPO membrane and let it sit in the sun to relax. This is critical. If you don’t let the material relax, you’ll fight wrinkles all day and end up with a sloppy-looking roof. Once it relaxed, we stretched it tight, removed the wrinkles, and started fastening. Our fastener spacing follows manufacturer specs exactly — that’s how you maintain your warranty.
Perimeter Details: On this job, we fully adhered the perimeter. That means we used adhesive along all the edges instead of just mechanical fasteners. It creates a stronger bond and better wind uplift resistance.
Flashing and Penetrations: Behind the fastening crew, we had technicians working on all the detail work. Every pipe, every penetration, every transition got flashed and sealed properly. This is where most roof leaks start, so we don’t rush this part.
Final Walkthrough: We inspected every seam, every detail, every corner. The owner got a roof that’s going to protect his building for decades if he keeps up with annual inspections.

Signs You Need TPO Roofing Services in Thomasville NC
How do you know when it’s time to call a commercial roofer? Here are the signs we see most often:
- Visible sagging around HVAC units: If your units have sunk into the roof, the decking or insulation underneath is compromised.
- Water stains on interior ceilings: By the time water shows up inside, you’ve been leaking for a while. Don’t wait until you see daylight through the deck — that means the roof has been failing for years.
- Cracking or splitting membrane: TPO eventually breaks down from UV exposure and thermal cycling. If you’re seeing cracks, you’re past due.
- Ponding water that doesn’t drain within 48 hours: Standing water accelerates membrane breakdown and adds weight to your roof structure.
- Your roof is over 15 years old: Even well-maintained TPO roofs have a lifespan. If you’re approaching that age, start planning for replacement.
- Failed seams: If seams are separating or if previous patches are failing, you need professional attention.
- You can’t remember your last inspection: If it’s been more than a year since a professional looked at your roof, schedule one now. Catching problems early saves serious money.
We see these issues regularly in Thomasville, Asheboro, Salisbury, and throughout the region. The climate here — hot summers, freezing winters, plenty of moisture — is tough on commercial roofs.

Frequently Asked Questions About TPO Roofing
How long does a TPO roof last on a commercial building?
A properly installed TPO roof typically lasts 20 to 30 years with proper maintenance. That means annual inspections at minimum, prompt repairs when small issues come up, and keeping the roof clear of debris. The installations that fail early almost always involve poor installation practices or zero maintenance. The material itself is durable when it’s installed correctly and cared for properly.
Can you install TPO over an existing roof?
Sometimes, but not always. It depends on the condition of the existing roof, the decking underneath, and local building codes. On the High Point project we just completed, we left the original roof in place in some areas but had to remove it in others where the decking was compromised. We replaced all the bad sections with new ISO board. Every building is different. We assess the existing conditions and recommend the approach that makes the most sense for your specific situation. If the decking is rotten, a recover won’t solve your problem — you’ll just be covering up failure with new material.
How often should I have my TPO roof inspected?
Annual inspections at minimum. If your building has heavy tree coverage or deals with a lot of debris, we recommend bi-annual inspections. Catching small problems early — a loose seam, a backed-out fastener, a small puncture — costs almost nothing to fix. Waiting until water is coming through your ceiling costs thousands. Most commercial building owners don’t think about their roof until there’s a problem. The ones who schedule regular inspections spend far less money over the life of their roof.
What’s the difference between TPO and other single-ply roofing membranes?
TPO, PVC, and EPDM are the three main single-ply options. TPO offers excellent UV resistance, good flexibility in cold weather, and heat-welded seams that create watertight bonds. It’s become the most popular choice for commercial roofs over the past 15 years. PVC performs similarly but costs more. EPDM is rubber — it’s been around longer but the seams are glued instead of welded, which gives you a potential weak point. For most commercial applications in our climate, TPO hits the sweet spot of performance and value.
