This page is for Little Gables homeowners who own Therma-Tru entry doors, patio doors, or trim systems and need roof work done right around them. It covers how we protect your Therma-Tru investment during a roof job, what actually fails on these systems in South Florida, and what the work should cost.
How Therma-Tru Products Fail - and How We Fix Them
Therma-Tru builds genuinely good doors, but Little Gables weather exposes weak points no brochure mentions. Here’s what we see on roof-adjacent Therma-Tru components, and what we do about it.
- Classic-Craft and Smooth-Star frame rot at the sill. Little Gables gets 60-plus inches of rain a year, and when roof flashing above a Therma-Tru entry door is even slightly off, water runs straight down the jamb and pools at the sill. The composite door skin holds up, but the wood frame behind it doesn’t. We pull the door, replace rotted framing with pressure-treated stock, re-flash the roof-to-wall intersection, and reset the unit. If you catch it early, the door itself is usually fine.
- Fiber-Classic door slabs warping from attic heat. This one surprises people. When a roof replacement removes old ventilation or a new underlayment traps more heat, attic temps in Little Gables climb past 140°F in August. Fiber-Classic doors on interior garage-to-attic access points can start to bow. We address this by checking attic ventilation during the roof job and recommending ridge vent or soffit improvements before the door gets reinstalled.
- Sill pan flashing gaps on Tru-Defense door systems. Therma-Tru’s Tru-Defense line is designed for impact zones, but the weather barrier only works if the sill pan and door flashing tie correctly into the roof drainage plane above it. On older Little Gables houses, we regularly find the original builder skipped that tie-in. We cut the wall, install a proper pan flashing that laps over the housewrap, and re-secure the door. This is a fix you won’t find on Therma-Tru’s website, because it’s about the house, not the door.
- Cracked door sweeps and weatherstripping after roof work. A roof replacement generates a lot of ladder traffic. If the crew isn’t careful, door thresholds and sweeps take abuse. We replace Therma-Tru sweeps with OEM or matching aftermarket parts and adjust the threshold so the door seals like it did new. It’s a small thing, but a door that drags will wear out its sweep in a season.
- Out-of-square rough openings discovered during roof replacement. When we open up a Little Gables roof, we occasionally find the wall plates have settled or shifted. A Therma-Tru door that fit fine for years starts binding at the top corner. We square the opening, shim the frame correctly, and re-hang the door per Therma-Tru’s installation specs. Done once, done right.
Our Therma-Tru Roof Replacement & Installation Process
Here’s exactly what happens when you call us for Therma-Tru-related roof work in Little Gables.
- 1
Call and talk to a person. You reach a live human at (727) 291-4678, not a voicemail tree. We ask about your roof, your Therma-Tru components, and any leaks or damage you’ve noticed.
- 2
On-site inspection. We walk the roof, check the decking, flashing, and every penetration, and we inspect your Therma-Tru doors and trim where they meet the roofline. You get a written report with our findings.
- 3
Parts and material decisions. We discuss OEM vs quality aftermarket for anything that touches the roof-to-wall connection. For Therma-Tru door components, we use factory parts where it matters; for roofing materials, we recommend what holds up in Little Gables humidity and wind.
- 4
Written line-item estimate. You get the full price before we start. Fixed, not an estimate that drifts. If you have a written estimate from anyone else, bring it in and we’ll give you a free second opinion.
- 5
The work. Tear-off, deck inspection, underlayment, flashing, roofing, and careful protection of your Therma-Tru doors and trim. Our technicians are background-checked and in uniform. You’ll know who’s on your property.
- 6
Cleanup, test, and walkthrough. We run water tests on all roof-to-wall intersections, check that doors still open and seal correctly, and walk the job with you. If anything’s not right, it’s covered by our Done Right Promise.
What Therma-Tru Roof Replacement & Installation Costs in Little Gables
Here are realistic ranges for Little Gables based on what we’ve seen and bid over the past several years. Your exact number depends on roof slope, access, decking condition, and material choice.
- Full tear-off and replacement, architectural shingles, 1,800 sq ft home: $9,800 to $14,500
- Tile roof replacement, 1,800 sq ft home: $16,000 to $24,000
- Metal standing seam roof, 1,800 sq ft home: $18,000 to $28,000
- Flashing and deck repair around Therma-Tru doors during roof work: $400 to $1,200 per door opening
- Attic ventilation upgrade (ridge vent, soffit vents): $600 to $1,800 depending on scope
What moves the price: decking rot that requires replacement, skylight or chimney flashing, roof pitch (steep roofs cost more in labor), and whether your Therma-Tru doors need sill or frame work. We give you the number upfront and it doesn’t change unless you change the scope. Call (727) 291-4678 to schedule a free estimate. And yes, we pull permits and pass inspections. It’s what we do.
Why Little Gables Homeowners Call Winslow Windows & Doors for Therma-Tru Work
Ed Winslow grew up in Little Gables, not far from the old Coral Gables Congregational Church, and he still lives a few miles from where he learned to ride a bike. He learned his trade fundamentals at Miami Dade College’s Kendall Campus before he ever set foot on a job site, and he’s spent the better part of two decades measuring, installing, and standing behind every window and door he touches in South Florida. His own family’s house took a beating during a bad hurricane season, and that’s a big part of why he got into this line of work. It’s also why the Done Right Promise means something here: if it’s not done right, we make it right. No fine print, no expiration.
We’re authorized installers for PGT, CGI, CWS, and ES Windows alongside Therma-Tru, so if your roof job turns up a damaged window or door from another brand, we handle that too. One crew, one point of contact, one owner accountable for the whole exterior. Every tech arrives background-checked and in uniform. And when you call, a live person answers. 24 hours a day, 7 days a week. That’s not a call center in another state. That’s us.
We also keep our standing offers permanent: $40 off any repair over $200, free second opinions on written estimates, no trip charge inside the home county, and a 10% discount for seniors and veterans. No expiration dates. No gimmicks.
My name is on the truck, so the work has to be right, every time.
FAQs
No, roof work itself doesn’t void your Therma-Tru warranty, but improper flashing or water intrusion around the door opening can cause damage that the warranty won’t cover because it’s installation-related, not a manufacturing defect. That’s why we re-flash every roof-to-wall intersection and check the door perimeter after the roof is on. Call (727) 291-4678 and we’ll walk you through what your specific warranty covers.
Yes, in most cases we can match Therma-Tru trim profiles and finishes using OEM parts or compatible aftermarket materials. If your roof replacement requires replacing water-damaged brickmold or trim around a Therma-Tru door, we’ll source a match so the door looks factory-fresh. Exact match depends on the age and line, but we’ll show you samples before anything gets installed.
Most Little Gables homes take 3 to 7 working days from tear-off to final inspection, depending on roof size, material, and weather. The door and flashing work happens alongside the roofing, not as a separate visit. Call (727) 291-4678 for a timeline based on your specific house.
Roof first, then doors, if you have the choice. A roof replacement exposes the top of the door openings, and you don’t want a brand-new Therma-Tru door getting ladder-scuffed or flashed incorrectly during roof work. When we do both, we sequence it so the doors go in last, after the roofing is watertight and the openings are verified.
Yes. The estimate is free, and there’s no trip charge if you’re inside the home county. You’ll get a written, line-item number. Call (727) 291-4678 to schedule.
