Commercial roof repair
Commercial roof repair that finds the real source.
Leaks on flat and low-slope commercial roofs rarely show up where the water starts. Golden Rule traces the problem, repairs it on the system you already have, and tells you plainly when repair is no longer the smart money.
Leak repair
The stain on the ceiling tile is the end of the story, not the start.
On a commercial building, water can travel a long way before it shows up inside. It slips under a lifted seam, runs along a deck flute or the top of insulation, and drips through a ceiling tile thirty feet from where it got in. Patching the spot above the stain usually just moves the leak.
Our commercial roof repair work starts on the roof, not in the office. We walk the area above the leak and well beyond it, checking seams, flashings, curbs, pipe boots, drains and anything else that penetrates the membrane. Once we find the actual entry point, we repair it with materials that are compatible with your existing system, and we photograph the before and after so you can see exactly what was done.
Elliot Thorpe, who owns and operates Golden Rule, spent years as a firefighter and a professional property inspector before running roofs full time. That background shows up in how we work: look at the whole picture, document what is there, and fix the cause instead of the symptom.
Flat & low-slope repair
Repairs on the systems commercial buildings actually use.
Most commercial roofs in North Texas are flat or low-slope, and each membrane type fails in its own way. A good repair matches the original system — the wrong patch material can fail early or damage the membrane around it.
If your roof is TPO, our TPO roofing page goes deeper on how that membrane is welded and repaired. If a roof has worn evenly across its surface but is still dry underneath, a commercial roof coating may be worth discussing alongside the repair.
- 01
TPO & PVC
Hot-air welded seam repair, patches over punctures, and re-welding seams that have opened from heat cycling or foot traffic.
- 02
EPDM
Seam tape and splice repair, patches over punctures and shrinkage pulling the membrane away from walls and edges.
- 03
Modified bitumen
Blisters, open laps, cracked or alligatored surfacing, and failed flashings at walls and curbs.
- 04
Commercial metal
Loose or backed-out fasteners, failed sealant at laps and trim, and rust-through at panel ends and gutters.
Emergency leaks
When water is coming in right now.
Active leaks over inventory, equipment, tenants or customers can't wait for a convenient week. Call or text 214-663-6108 and describe what you are seeing. When weather allows us on the roof safely, we work to stop the water first with a temporary measure, then come back with a proper, permanent repair once conditions are dry enough to do it right.
Before we arrive, a few steps help: move what you can away from the drip, set out containers, and keep people out of wet areas. If you can safely see the roof from a ladder or roof hatch, check whether any drains or scuppers are clogged — standing water finds its way through any weak spot.
If the leak follows hail or high wind, the damage may go well beyond one spot. Our commercial storm restoration process covers a full roof assessment and documentation you can use if you decide to file a claim with your carrier. You file the claim; we handle the roof and can be on site when the adjuster inspects.
Repair or replace
When repair stops making sense.
We would rather tell you a roof has more life in it than sell you one you don't need. Plenty of commercial roofs only need a well-placed repair and some routine attention. But there is a point where you are paying to chase leaks across a roof that has reached the end of its useful life.
Signs we look for: leaks returning in new places after each repair, wet insulation spreading under the membrane, seams failing across large areas instead of in one spot, widespread shrinkage or brittleness, and decking that feels soft or shows rust. When we see those, we will show you the photos and talk through your options honestly.
If replacement is the right call, our commercial roof replacement page walks through system options and how we keep your building operating during the work. If the roof is still sound, setting up commercial roof maintenance is the best way to keep small repairs small.
What you get
Straight answers and a clean record of the work.
Every repair visit ends with a plain-English explanation of what we found, what we fixed, and anything else we noticed that you should keep an eye on. You get photos of the problem and of the finished repair, which is useful for your own records, your tenants, ownership or the next person who manages the building.
Not sure what is going on up there? A commercial roof inspection gives you a full written picture of the roof before you decide anything. Golden Rule is insured, owner-operated and based in Denton, TX — and we treat every building the way we would want ours treated. Learn more about our overall approach on the commercial roofing page.
Common questions
Straight answers.
How fast can you get out for a commercial roof leak?
Call or text 214-663-6108 and tell us what is happening. Active leaks get priority, and we work to stop the water with a temporary measure as soon as it is safe to be on the roof, then return for the permanent repair.
Can you repair any kind of commercial roof?
We repair TPO, PVC, EPDM, modified bitumen and commercial metal roofs, and we apply roof coatings. We do not work on gravel-top built-up roofs. If you have an older gravel roof that needs work, we can talk through replacing it with one of the systems we install.
Why does my roof keep leaking after it was patched?
Usually because the patch was placed over the stain inside instead of at the actual entry point, or because the patch material wasn't compatible with the membrane. We trace the water path on the roof before we repair anything.
How do I know if I need a repair or a replacement?
If problems are isolated and the roof is mostly dry, repair usually makes sense. If leaks keep returning in new places, insulation is wet across large areas, or seams are failing roof-wide, replacement may be the better investment. We show you photos and explain our reasoning either way.
Are you insured?
Yes. Golden Rule Roofing Group is insured, and we are happy to send proof of insurance to you or your property manager before work begins.
