Therma-Tru Shingle, Tile & Metal Roofing in Westchester: What to Know First
Therma-Tru shingle, tile and metal roofing work in Westchester typically costs between $425 and $1,850 depending on whether we’re repairing a single section or replacing an entire roof plane, and most repair jobs are completed in a single day. We’re an independent Therma-Tru service provider, not a manufacturer affiliate, and we service the full exterior of Westchester homes including doors, windows, and roofing systems. If you’re a homeowner near Bird Road or the Palmetto who needs straight answers about your Therma-Tru roofing products, call (863) 251-5864 and a live person picks up, day or night.
How Therma-Tru Roofing Products Fail - and How We Fix Them
Therma-Tru earned its reputation on fiberglass and steel door systems, but many Westchester homes also carry their roofing accessories, flashing kits, and integrated trim. Here’s what actually goes wrong with them in South Florida conditions, and how we address each one.
- Therma-Tru door-to-roof flashing separation. On homes where a Therma-Tru entry or patio door meets a shingle or tile roofline, the original flashing often pulls away after a few hurricane seasons. We see it constantly in Westchester’s older ranch homes off SW 24th Street. The fix is a full re-flash with replacement step flashing, not a bead of caulk over the gap. Caulk fails in one summer; proper flashing lasts decades.
- Therma-Tru transom and sidelight assemblies leaking into roofing underlayment. The classic symptom is a water stain on the ceiling near the front door, not at the door itself. Water enters at the header flashing, travels along the roof deck, and shows up six feet away. We remove the trim, inspect the roof-to-wall junction, and rebuild the weather barrier before reinstalling the Therma-Tru assembly.
- Tile roof fastener corrosion around Therma-Tru skylights and vents. Westchester’s salt air and humidity chew through cheap fasteners fast. When original Therma-Tru roof integration hardware corrodes, tiles loosen and water gets under the underlayment. We swap in stainless fasteners and re-seat the tile to manufacturer torque specs.
- Shingle granule loss and membrane wear at Therma-Tru roof curb junctions. Therma-Tru roof curbs under older A/C units or exhaust fans on Westchester homes tend to collect debris and moisture. The shingles around them degrade faster than the rest of the roof. We replace the affected shingles, rebuild the curb flashing, and give you an honest read on how much life the surrounding roof has left.
- Metal roof panel oil-canning near Therma-Tru door overhangs. On metal roof sections that tie into Therma-Tru entry canopies, we occasionally see panel buckling from thermal expansion when the original installer over-tightened fasteners. We correct the fastening pattern and replace affected panels with a proper expansion allowance. It’s a nuance most crews miss; our techs check for it on every metal roof inspection in Westchester.
Our Therma-Tru Shingle, Tile & Metal Roofing Process
Here’s how a typical Therma-Tru roofing job goes when you call us in Westchester.
- 1
You call (863) 251-5864. A live person answers. We schedule a visit that fits your week and tell you up front there’s no trip charge in our home county.
- 2
One of our techs walks the roof and the door assemblies. We inspect the roof-to-Therma-Tru junctions, the flashing, the fasteners, and the underlayment. You get a written line-item report with photos of what we find.
- 3
We give you a fixed price with the parts decision spelled out. If OEM Therma-Tru trim or flashing is needed, we quote it. If a quality aftermarket part will perform identically and cost less, we tell you that too - and we never substitute without your written approval.
- 4
The work gets done right the first time. We pull any required permits, complete the repair or replacement, and clean up so the only sign we were there is a properly sealed roof.
- 5
We test the repair. Before we leave, we water-test the affected area and check for any fastening or flashing issues on the surrounding roof surface.

The 36500-Day Done Right Promise kicks in. If it’s not done right, we come back and make it right. Ed’s name is on the door - and on every job we do.

FAQs
Therma-Tru’s warranty covers their door and window products themselves, but typically not the roofing flashing, underlayment, or fastener work done by third-party installers. As an independent Therma-Tru service provider, we work with you to determine what the manufacturer will cover and what falls to your roofing system. Call (863) 251-5864 and we’ll help you sort it out, free.
In most cases yes - Therma-Tru’s current trim profiles and finishes are widely available through our supply network, and we can match most Westchester homes with factory colors or a very close aftermarket equivalent. We’ll show you samples before ordering so there are no surprises. Call (863) 251-5864 and we’ll check your specific model.
If the flashing has failed once, replacement is usually the smarter long-term move in Westchester’s climate. Repair can buy time on a new roof, but if your shingles or tiles are past 15 years old, you’ll likely save money by replacing the affected roof section and flashing together. We’ll give you an honest read on what the roof actually needs - not what sounds good on a sales sheet.
We answer live around the clock and typically schedule within a few days for non-emergency roofing work. If you’ve got an active leak at a Therma-Tru door junction, tell the person who answers and we’ll prioritize it. Call (863) 251-5864.
When a job requires a permit under local Westchester or Miami-Dade code, we pull it and make sure the inspection passes before we call the job complete. Permits protect you, and we don’t cut corners on them. Call (863) 251-5864 for a free estimate and we’ll tell you exactly what applies to your roof.
My name’s on the business. That means the job doesn’t end when we pull out of your driveway.
