Therma-Tru Roof Repair in Westchester: What to Know First
Therma-Tru roof repair in Westchester means working on homes where a Therma-Tru product - most often a skylight, a roof-mounted vent window, or an integrated frame assembly - has failed at the roof line. We repair these systems, usually within one to two days of your call, and we price the job before we start so you know the number before a single tool comes off the truck.
This page is for Westchester homeowners who own a Therma-Tru product and have noticed a leak, a crack, fogged glass, or water staining near the roof. You’re not looking for a sales pitch - you want to know what’s wrong, what it costs, and who can fix it without creating three new problems. Call (850) 721-1218 and you’ll get a live person, not a voicemail tree.
How Therma-Tru Products Fail - and How We Fix Them
Therma-Tru builds high-quality entry doors and surrounding frame systems, but in Westchester’s sun-and-rain cycle, anything mounted at or near the roof line takes a beating. Here are the failure modes we see most often on Therma-Tru assemblies in this neighborhood:
- Frame-to-roof flashing separation on Therma-Tru Classic-Craft assemblies. The Classic-Craft line uses a fiberglass skin over a wood-grain frame. In Westchester’s wet season, the thermal expansion difference between the door frame and the roofing membrane gradually pulls the flashing off its seal. Water creeps behind the frame and tracks down the wall. Our fix: remove the old flashing, inspect the sheathing, install new membrane-style flashing with proper shingle overlap, and re-bed the frame with a polyurethane sealant rated for Miami-Dade humidity swings.
- Skylight glazing seal failure on Therma-Tru roof window units. The glazing gasket between the glass and the aluminum frame breaks down after years of direct Miami sun. You’ll notice condensation between the panes or a slow drip after a hard afternoon downpour. We replace the gasket with an OEM-spec material and re-seat the glass, which restores the thermal seal without replacing the entire unit.
- Threshold and bottom-sweep rot on Therma-Tru Smooth-Star doors mounted near roof drains. Roof drains that dump water too close to a door accelerate rot at the threshold. Smooth-Star’s fiberglass skin protects most of the slab, but the bottom sweep and its mounting channel take direct splash. We replace the sweep, repair any damaged sub-sill, and often recommend a simple splash block or diverter so the problem doesn’t come back.
- Missing or degraded boot flashing around Therma-Tru vent stack collars. Many Westchester roofs route plumbing vents through Therma-Tru collar assemblies. The rubber boot dries out and splits in five to seven years of direct UV exposure. Water follows the vent pipe straight into the attic. We replace the boot, re-tar the collar, and check the surrounding shingles for lifted tabs or nail pops.
- Compression seal failure on Therma-Tru multi-point locking door frames. When a door at the roof deck or a second-story exterior landing loses its compression seal, wind-driven rain from the east off the Everglades gets pushed right past the weatherstripping. We re-align the strike plates, replace the compression gasket, and re-test the door under a hose spray that simulates a storm-driven angle, not a gentle sprinkle.
Our Therma-Tru Roof Repair Process
- 1
Call us. A live person answers (850) 721-1218, day or night. We ask what you’re seeing, which Therma-Tru product is involved, and when the problem started. If it’s an active leak, we move fast.
- 2
Diagnostic visit. Ed Winslow or a senior tech comes to your Westchester home, inspects the assembly from both sides - roof and interior - and traces the actual water path. We don’t guess. We find the entry point.
- 3
Straightforward quote. You get a written line-item price before any work is approved. No “we’ll see once we open it up” pricing games.
- 4
The repair. We source OEM Therma-Tru parts when they’re available and the best choice. When a quality aftermarket part outlasts the OEM equivalent - the rubber boot on the vent collar is a good example - we tell you and explain why.
- 5
Water test. We flood-test the repaired area with a hose at storm-driven angle before we call the job done. If it doesn’t hold, it’s not done.
- 6
Cleanup and walkthrough. We leave your property cleaner than we found it and walk you through exactly what we did and why. The Done Right Promise covers the work we did.

Why Westchester Homeowners Call Winslow Windows & Doors for Therma-Tru Work
We’re the one down the road, not a call center three states away. Winslow Windows & Doors has been serving Westchester since 2011 - Ed Winslow grew up here, a few minutes from Tropical Park, and his name is on the truck. My name is on the truck. That means I stand behind every window and door we touch.
Our techs are background-checked and arrive in uniform. They know Therma-Tru’s frame systems, and if your roof repair reveals a larger issue with a neighboring product - a PGT impact window, a CGI door, a CWS frame, or an ES Windows unit - we service those too as authorized installers. One crew, one call, one owner who answers the phone. Upfront pricing. No surprises on the invoice.
FAQs
No. As an independent Therma-Tru service provider, we use OEM parts when available and repair methods that preserve your warranty standing. The work we perform is covered by our Done Right Promise regardless of manufacturer warranty status. Call (850) 721-1218 if you’re unsure where your product stands.
Most common Therma-Tru parts - sweeps, gaskets, flashings, weatherstripping - are available locally or in one to two days through our South Florida suppliers. We’re not waiting on a slow national distribution chain when your roof is leaking. Call and we’ll tell you honestly what the lead time looks like for your specific repair.
If the frame is sound and the issue is a failed gasket, a cracked boot, or a separated flashing, repair almost always makes sense - costs less, done faster. If the glass is cracked or the frame shows rot at structural points, replacement is the honest call. We’ll show you the numbers for both before you decide.
No. The price we quote is the price you pay. If we discover hidden damage - rotted sheathing, for example - we stop and bring you photos and a revised number before touching anything else. The only surprise you’ll get from us is how clean the job site looks when we leave.
Both. The failure point is almost always where the Therma-Tru assembly meets the roof, so we handle the roofing side - flashing, boots, membrane seals, and shingle repair - as an integrated job. That’s why Westchester homeowners call us instead of juggling two contractors who each blame the other.
