Therma-Tru Roof Repair in West Palm Beach: What to Know First
Therma-Tru roof repair in West Palm Beach typically runs between $350 and $1,900 depending on whether we’re sealing a failed deck-to-wall flashing joint or rebuilding a rotted eave assembly around a Therma-Tru door frame. Most jobs are done in one visit, and we give you a written line-item quote before any tool comes off the truck. If you’re a West Palm Beach homeowner with a Therma-Tru entry or French door leaking at the roofline, this page tells you exactly what we see, what we do, and what it costs.

How Therma-Tru Products Fail - and How We Fix Them
Therma-Tru makes a solid door. The roof leaks we deal with usually aren’t the door’s fault, they’re where the house meets the door. Here’s what fifteen years of West Palm Beach roof repair has taught us:
- Sill pan corrosion on Classic-Craft and Fiber-Classic models. Therma-Tru’s composite door slabs hold up fine against Florida humidity, but the factory sill pan under an older install collects water that wicks up into the brickmould. By the time a homeowner sees staining on the interior drywall, the sub-sill is already spongy. We pull the door, replace the rotted rough opening, and flash the sill correctly with a sloped pan and backer rod before anything goes back in.
- Roof flashing separation at the door header. West Palm Beach homes built in the 1980s and 1990s often have step flashing that stops two inches short of a Therma-Tru door’s brickmould. Hurricane-driven rain finds that gap every single time. We cut back the stucco, extend the flashing into the door’s factory kerf, and overlay a custom bent head flashing. That’s the repair that stops the call you make after every heavy storm.
- Rotted eave returns above Therma-Tru Smooth-Star doors. Smooth-Star doors get specified on lots of mid-century ranch houses in neighborhoods like Northwood Hills and Flamingo Park, where the eave return sits directly above the entry. When the eave return traps pine needles and oak litter, water backs up under the shingles and runs straight down the door’s side jambs. We rebuild the eave with pressure-treated stock, re-shingle the return, and re-flash the door header while we’re in there.
- Improperly sealed transom assemblies above Therma-Tru patio doors. A transom window above a door is a leak waiting for bad flashing. We see a lot of Therma-Tru sliding patio doors in West Palm Beach with transoms that were caulked instead of flashed. The caulk fails in two seasons of sun and rain. We install a continuous Z-flashing across the transom base with end dams, then re-set the transom frame in a bed of sealant over the flashing, not under it.
- Kick-out flashing missing at Therma-Tru side-entry doors. Any door set into a wall where the roof edge runs toward it needs kick-out flashing at the gutter or roof-wall junction. When it’s missing, water sheets down the roof, runs right past the gutter, and pours onto the door’s top brickmould. We add a proper kick-out diverter and re-route that water away from the entry. It’s a two-foot fix that saves a two-thousand-dollar door rebuild.
Our Therma-Tru Roof Repair Process
Every Therma-Tru job in West Palm Beach follows the same sequence, so what you see on the work order is exactly what happens:
- 1
Inspection and water tracing. We start at the interior stain and trace backward. Is it the door, the flashing, the roofline, or the gutter? We find the actual source before recommending anything, and we’ll show you photos of the failure.
- 2
Written line-item estimate. Every repair gets priced upfront, separated by labor, materials, and disposal. No change orders unless we open a wall and find rot that couldn’t be seen from outside, and we stop and call you before touching that.
- 3
Parts decision: OEM versus quality aftermarket. For Therma-Tru-specific trim, brickmould, and sweep components, we use factory parts so the fit is exact and the warranty stays intact. Flashing, sealants, and framing stock are job-specified by material and rating, so you get the right product for a salt-air environment.
- 4
The repair itself. Flashing, sealing, rebuilding, whatever the job calls for. Our techs are background-checked and uniformed, and Ed Winslow’s name is on every work order.
- 5
Water test before we leave. We run a garden-hose soak at the repair zone, then verify no water moves past the penetration. You see the test result before we call it done.
- 6
The Done Right Promise. If it’s not done right, we make it right. That’s a standard of accountability written into every job.
What Therma-Tru Roof Repair Costs in West Palm Beach
Here’s what we typically quote for the Therma-Tru roof repair scenarios West Palm Beach homeowners bring us:
- Header flashing replacement over a Therma-Tru door: $350 to $650, depending on stucco work required.
- Full sill pan replacement with rough-opening repair: $850 to $1,600 if we need to pull and re-set the door slab.
- Eave return rebuild and re-shingle above a door: $700 to $1,400, depending on eave length and rafter condition.
- Transom flashing and re-seal: $500 to $1,100, including re-bedding the transom frame.
- Kick-out flashing and roof-wall junction repair: $300 to $600 when the fascia and rafters are sound.
What moves the price is rot. Once water has been getting in for a while, the rough opening and sub-floor need to come out and get rebuilt, and that’s where the labor hours go. We always show you the rot before we price the fix. Every estimate is free, so call (561) 660-9539 and get a real number for your specific door and roof condition.
