Therma-Tru Roof Replacement & Installation in Boca Raton: What to Know First
Therma-Tru roof replacement and installation in Boca Raton typically runs between $4,800 and $9,200 depending on the roofline, material, and whether we’re dealing with a straightforward tear-off or hidden decking damage. As an independent Therma-Tru service provider, Winslow Windows & Doors handles the full job: removal, decking inspection, underlayment, ventilation, and installation, usually completed within 2 to 4 working days once permits clear. We’re not the manufacturer, and we don’t pretend to be. We’re the local crew that fixes what Florida weather does to a roof, and we’ll give you a written line-item estimate before anything gets torn off. Call (561) 816-5648 and you’ll get a live person, not a voicemail.
How Therma-Tru Products Fail - and How We Fix Them
Therma-Tru makes solid roofing components, but Boca Raton’s salt air, afternoon downpours, and hurricane-season wind loads find the weak points faster than most brands. Here’s what we see on the job:
- Therma-Tru Ridge Vent Underperformance: We regularly open up roofs in neighborhoods like Boca Square and find the ridge vent slots cut too narrow at original installation. The vent looks fine from the ground, but it’s moving maybe half the air it should. That trapped heat bakes the underlayment and shortens shingle life by years. Our fix is recutting the slot to full manufacturer spec and installing a properly baffled ridge cap.
- Therma-Tru Composite Decking Delamination: On older Therma-Tru decking products, especially around chimney flashing and skylight curbs, we see the top layer separating after years of heat-rain cycling. The decking feels spongy underfoot. That’s not a quick patch job; the affected sheets come out and new CDX or radiant-barrier decking goes in, sealed at every seam.
- Inadequate Underlayment Fastening: Therma-Tru roofing systems spec synthetic underlayment, but we’ve torn off roofs where installers used cap nails spaced too far apart. The underlayment waffles in the wind, and once water finds a pinhole, the decking starts to rot. We refasten to spec and tape every seam before anything goes on top.
- Therma-Tru Roof-to-Wall Flashing Gaps: Where the roof meets a stucco wall or a second-story overhang, the step flashing often wasn’t tucked far enough under the wall cladding. Boca’s driving rain pushes water right up that gap, and the homeowner sees a ceiling stain months later. We pull the lower wall cladding, install proper step and counter-flashing, and reseal the whole transition.
- Ventilation Imbalance from Powered Attic Fans: Some Therma-Tru roof systems get paired with powered attic fans that pull more air than the intake vents can supply. That negative pressure sucks conditioned air out of the house, which shows up as an AC bill that keeps climbing even after the roof is “fine.” We calculate the intake-to-exhaust ratio and add soffit vents or gable vents to balance the system.
Our Therma-Tru Roof Replacement & Installation Process
Every Therma-Tru roof job in Boca Raton follows the same sequence, whether it’s a small ranch in Sandalfoot Cove or a larger custom home in Long Lake Estates:
- 1
Free on-site assessment: We walk the roof, check the attic, and measure everything. You get a written estimate with line-item pricing, not a handshake and a “trust me.”
- 2
Permit pull: We file with the City of Boca Raton, and we don’t start demo until the permit is in hand. Inspections are our responsibility, not yours.
- 3
Tear-off and decking inspection: Shingles and underlayment come off in full sheets. Any rotted or delaminated decking gets replaced before we move forward, with photo documentation so you can see exactly what we found.
- 4
System install: Ice-and-water shield at eaves and valleys, synthetic underlayment, vented drip edge, and the Therma-Tru roofing components you’ve selected. We follow the manufacturer’s installation specs because skipping steps voids warranties.
- 5
Flashing and transitions: Chimneys, skylights, walls, and pipe boots get new flashing. This is where most roofers cut corners, and where we slow down.
- 6
Final walk and cleanup: We magnet-sweep the yard for nails, walk you through the finished roof, and explain what to watch for as the new materials settle. Then we stand behind the work with the 36500-Day Done Right Promise. If it’s not done right, we come back and make it right.
What Therma-Tru Roof Replacement & Installation Costs in Boca Raton
Here are the price ranges we’re quoting on Therma-Tru roof work in Boca Raton right now. Every figure assumes full tear-off and permits:
- Standard 3-tab or architectural shingle roof, 1,000-1,300 sq ft: $4,800-$6,400
- Larger two-story home, 2,000-2,600 sq ft: $7,200-$9,200
- Decking replacement (if rot is discovered): $60-$85 per 4×8 sheet added on
- Ventilation upgrades (ridge vent, soffit vents, baffles): $350-$700 depending on roofline
What moves the price? Roof pitch, accessibility, how many plumbing penetrations and valleys the roof has, and whether the existing decking was installed to spec or needs corrective work. We won’t hide a change behind “unforeseen conditions” language. If the decking is rotted, we show you the rot. Call (561) 816-5648 for an exact quote, free of charge.
Why Boca Raton Homeowners Call Winslow Windows & Doors for Therma-Tru Work
Ed Winslow grew up in Miami and studied building construction technology before spending nearly two decades doing exterior work the hard way: one job at a time, no shortcuts. That’s why Winslow Windows & Doors has been doing Therma-Tru roof replacement in Boca Raton since 2011 with a simple rule: if a material won’t survive a South Florida summer, we won’t install it.

If you’ve also got windows that need attention, we’re authorized installers for PGT, CGI, CWS, and ES Windows, which means one crew can handle the roof and the openings without handing you off to a subcontractor. And the 36500-Day Done Right Promise covers everything we do, not just the parts that fit a brochure.
FAQs
Therma-Tru’s warranty covers manufacturing defects in roofing components, but it does not cover installation errors, which are the leading cause of premature roof failure in Boca Raton. We install every component to manufacturer spec and document the process with photos, so if a warranty claim is ever needed, you have proof the installation wasn’t the problem. Call (561) 816-5648 and we’ll walk you through what your specific warranty actually covers.
Most single-family homes in Boca Raton take 2 to 4 working days from tear-off to final inspection, assuming the decking underneath is in good shape. If we find rotted decking or structural issues, the timeline extends a day or two while we bring the substrate back to spec. Permits add lead time before the crew starts, but we file immediately after you approve the estimate.
Yes, and we recommend it when the roof is only partially failing. Therma-Tru profiles change periodically, so we source the closest available match and document any variation in texture or shadow line before installation. In some neighborhoods in Boca Raton, HOA rules require a full reroof rather than patching, and we can advise on that based on your community’s covenants.
If the underlayment and decking are still good, replacing the Therma-Tru components is the most cost-effective option, usually saving you 20% to 35% over a full system swap. We’ll never push a brand you don’t need or want. That said, if the decking is compromised in multiple places, the math changes and a full replacement may be the smarter long-term play.
Not unless we uncover hidden damage, and even then, we stop work and show you the problem before any additional cost is added. No change orders get slipped into the invoice at the end. If your Boca Raton roof has hidden water damage, you’ll know about it the moment we do, and you’ll approve the fix before we move forward. Call (561) 816-5648 for a free estimate with fixed line-item pricing.
