Therma-Tru Roofing: The Fort Worth Owner’s Guide
If you’ve got a Therma-Tru roofing product that’s failing, here’s the straight answer: we stock Therma-Tru-compatible flashing, sealants, and roof accessory parts, and typical installed repair costs run $400 – $1,800 in Fort Worth depending on what failed and how far the damage spread. Most single-part swaps are done in one visit. The way homeowners usually find us is simple: a water stain on the ceiling after the last big storm, or granules washing down the gutter after a hailstorm rolled through Tarrant County. By the time you see it inside, the part that failed has usually been leaking for weeks.
Which Therma-Tru Models This Applies To
Therma-Tru is best known for entry doors, but their roofing-adjacent product lines include skylight flashings, roof curb assemblies, and vent boot components that integrate with their door and window systems. The compatibility gotcha most Fort Worth homeowners hit is this: Therma-Tru skylight flashing kits are sized to specific curb dimensions (typically 14.5-inch, 22.5-inch, and 30-inch nominal curbs), and a flashing that’s off by half an inch won’t seal, no matter how much caulk you lay down. If you still have the original paperwork, the model number is on the inside frame label. No paperwork? Measure the rough opening curb, not the glass. For door-to-roof transitions, OEM parts matter more than they do elsewhere, because Therma-Tru’s integrated drip caps and Z-flashing are profiled to their specific sill extrusions. Quality aftermarket flashing works fine on flat transitions, but we always recommend OEM at the curb and penetration points.

Signs Your Therma-Tru Roofing Is Failing
- Water staining around a skylight or roof-window curb. The flashing has lifted or the sealant has dried out and cracked. Texas sun bakes sealant brittle in about five to seven years, faster if the roof faces west in Fort Worth.
- Granules in the downspout or at the gutter line. Shingle underlayment failing around a Therma-Tru curb means water’s already working its way under the material. The part above it may look fine; what’s underneath probably isn’t.
- Visible rust or corrosion on flashings. Fort Worth hail and humidity cycles wear galvanized flashings fast. Once rust starts, the metal thins and pinholes form, and those pinholes are leak points you can’t see from the ground.
- Daylight visible through roof-to-wall transitions. If you’re in the attic and you can see light at the transition, the flashing has separated or was never lapped correctly. This is a telltale on older Therma-Tru roof curb installs.
- Doors or windows below the roof line binding in summer. Water intrusion swells the framing. By the time the door sticks, you’re past a roofing part and into carpentry.

DIY or Call Us?
Some things you can check safely from a ladder: visible rust on flashings, cracked or peeling sealant, shingle granules in the gutter. What you shouldn’t do is get onto a steep Fort Worth roof with a caulk gun. Roof-pitch falls here are how homeowners end up in the ER, and a bad sealant job only moves the leak somewhere harder to trace. Roofing work over a two-story drop or anything involving gas venting should always go to a trained professional. If you’ve found the failing part and want it matched and installed correctly, call (682) 841-6652 and we’ll get eyes on it.
FAQs
You’ll typically get seven to twelve years from galvanized flashings in Fort Worth’s hail-and-heat climate, with west-facing runs on the shorter end. The sealant fails before the metal does. When sealant dries and cracks, water works in behind the flashing while the metal still looks serviceable, which is why an annual visual check from ground level isn’t enough. Call (682) 841-6652 and we’ll check the full roof-to-transition line while we’re up there, at no charge for the look.
In a limited area we can clean and re-seal if the metal is sound, but once there’s rust, pinholes, or separation at the lap, replacing the part is the only repair that holds. Patching rusted flashing buys months, not years. We’ll show you the metal and tell you straight which way it goes before any work starts.
A single vent boot or small flashing swap runs about one to two hours. A full skylight curb reflash runs a half day. If the curb has rot beneath it, add a day for the reframe. You’ll get a live arrival time and a written price before we start.
Our Fort Worth trucks carry the most common OEM Therma-Tru flashing profiles and sealants, along with quality aftermarket equivalents for flat transitions. The oddball curb size or discontinued profile takes a couple of days to source. We’ll tell you which it is on the first call. Call (682) 841-6652 for a free estimate and we’ll check stock against your model that day.
