Therma-Tru Roof Replacement & Installation in Fort Lauderdale: What to Know First
Therma-Tru roof replacement and installation in Fort Lauderdale typically runs between $1,400 and $3,200 for a full door-and-roof assembly on a standard single entry, depending on whether you’re replacing the roof cap only or the entire frame assembly. As an independent Therma-Tru service provider, we handle the full job from tear-out to final caulk, and most residential replacements are done in a single day. We’re not the cheapest bid you’ll get, and we won’t pretend otherwise. What we give you is a written line-item quote, both warranty layers registered in writing before our truck leaves your driveway, and a 90-day Done Right Promise on the workmanship.
This page is written for the Fort Lauderdale homeowner who has a Therma-Tru entry door that’s been leaking, rotting, binding, or losing its finish for years and wants to understand what the fix actually involves. If that’s you, call us at (754) 310-3589. A live person answers, day or night.
How Therma-Tru Products Fail - and How We Fix Them
We’ve pulled enough Therma-Tru doors off Fort Lauderdale houses to know their failure patterns better than any brochure will tell you. Here’s what we see week after week and what we do about it:
- Fiber-Classic roof cap delamination: The Fiber-Classic line uses a compression-molded fiberglass skin over a wood frame. In Fort Lauderdale’s salt air and wet season, we see the skin separate from the frame at the top corners of the roof cap where water pools. The fix isn’t caulk on the surface. We remove the cap, inspect the underlying rail for rot, treat the wood if salvageable or replace the rail if not, then reset the cap with proper flashing and a manufacturer-spec sealant. Surface caulk over delaminated fiberglass lasts about eight months before the sun opens it back up.
- Smooth-Star top rail water intrusion: Smooth-Star doors have a polyurethane foam core that resists rot, but the top rail is still a weak point. In side-by-side townhouses in Flagler Village where doors face east into the morning storms, we regularly pull off roof caps to find water has followed the screw holes from a previous installer’s poorly flashed cap straight into the rail. The core survives; the hardware doesn’t. We replace the cap, seal every screw with polyurethane sealant, and set a drip edge so water sheds away from the frame.
- Classic-Craft hinge-side sag: Classic-Craft doors are heavy, and twenty years of Fort Lauderdale humidity cycles cause the jamb to flex. The roof cap then sits out of plane, which opens a gap at the top right or left corner of the door. You notice it as daylight at the top corner or a latch that won’t catch in August. The fix is not to shim the cap. We pull the cap, reset the jamb fasteners, plane the rail if needed, and reinstall the cap so the door closes square.
- Warped top frame from improper installation: We see this on Therma-Tru doors installed by generalists who didn’t flash the rough opening before setting the frame. Fort Lauderdale’s soil shifts, the concrete settles, and the frame torques. The top edge of the door starts binding, and the roof cap twists with it. We remove the entire top assembly, level the frame, re-shim the railing, and reset everything. This is a two-person job when done right, and it’s the reason our techs measure every opening twice before touching a screw.
- Aftermarket roof cap misfit: When a previous contractor replaced a Therma-Tru cap with a generic aftermarket unit, the reveal lines don’t match and the cap sits proud by an eighth inch on one side. It looks wrong, and it leaks. We order the correct profile or fabricate the cap to match the original reveal, then paint the assembly to match the door face. Dale Kessler’s rule on this one is simple: if the pane is not true, the job is not done. Same rule applies to a roof cap.
Our Therma-Tru Roof Replacement & Installation Process
- 1
You call (754) 310-3589. A live person answers, no call tree, and schedules a visit at a time that works for you. We show up when we say.
- 2
We measure and diagnose. Our tech reads the existing framing before quoting anything. We measure the rough opening, check the sill for rot or settlement, and determine whether the failure is in the roof cap, the frame, or both.
- 3
We quote on paper. You see the line items: cap replacement, rail repair, flashing, sealant, paint match. No vague “labor and materials” line. If the frame is still sound, we tell you why and quote only the cap. If the frame is failing, we say so and explain what replacement involves.
- 4
We do the work. Tear-out, rot repair, new cap or full assembly, step flashing, corner seals, and a drip edge where the opening allows. We use OEM Therma-Tru parts when the original profile is still available and quality aftermarket profiles when it’s not, and we tell you which you’re getting and why.
- 5
We test and register. We close the door, check the reveal all around, run a water test on the cap, and confirm the latch sets cleanly. Then we register both warranty layers in writing before the truck leaves the driveway.
- 6
We stand behind it. The 90-Day Done Right Promise covers the workmanship. If something’s not right, we fix it. No paperwork argument.
What Therma-Tru Roof Replacement & Installation Costs in Fort Lauderdale
Here’s what we quote most often in Fort Lauderdale, where salt air and wet-season humidity wear on entry doors harder than most of the country:
- Roof cap replacement only (cap, flashing, sealant, paint match): $220 to $480 depending on cap profile and finish.
- Roof cap with top rail repair (rot removal, wood treatment, new cap): $480 to $900.
- Full Therma-Tru roof assembly replacement including frame rail: $900 to $1,600.
- Complete Therma-Tru entry door replacement with new roof assembly and installation: $1,400 to $3,200, depending on door size, glass package, and finish.
What moves the price: whether the frame is sound or compromised, the age of the door (older profiles are harder to match), and whether you have a sidelight or transom that also needs attention. We give you a fixed price in writing before work begins. No change orders mid-job. Call (754) 310-3589 for your free estimate.
Why Fort Lauderdale Homeowners Call TruePane Windows & Doors for Therma-Tru Work
TruePane Windows & Doors has been serving Fort Lauderdale and the surrounding communities for over 42 years through a heritage of craft. We’re a second-generation glazier’s shop, founded by Dale Kessler in 2008 on a principle that out-of-true installs and voided warranties were problems worth fixing permanently. We’re an authorized installer for more than a dozen manufacturer lines, including Andersen, Pella, Marvin, Milgard, Jeld-Wen, PGT, CGI, and ES Windows. When we work on a Therma-Tru roof, we bring the same discipline we use on impact windows: measure twice, spec it right, and put it in writing, because the frame does not forgive shortcuts.
Every job is covered by the 90-Day Done Right Promise. Both manufacturer warranty layers get registered in writing before the truck leaves the driveway. If it’s not done right, we make it right, no arguing. And if we find the Therma-Tru door isn’t worth saving, we can put a PGT, CGI, CWS, or ES Windows unit side by side on paper so you see exactly what you’re buying and what it costs. A live person answers every call, 24/7, because we plan to be in this town thirty years from now.
FAQs
In most cases we can replace just the roof cap, provided the frame rail underneath is still sound. The cap is a separate component, and replacing it with the correct profile restores the water seal and the look. If the rail has rot or the frame has shifted, a cap-only repair won’t hold, and we’ll tell you that before quoting. Call (754) 310-3589 and we’ll assess it in person.
Work done by an independent Therma-Tru service provider does not automatically void the original door warranty, but improper installation can. We use manufacturer-spec sealants and flashing details that protect the warranty, and we register both warranty layers in writing when the work is complete. Call (754) 310-3589 for a quote.
A roof cap replacement takes about half a day from tear-out to final caulk. A full frame assembly replacement runs a full day. Larger jobs with sidelights or transoms can stretch into a second morning. We tell you the timeline in the written estimate before we start, and most jobs are done in a single visit.
Fort Lauderdale’s summer humidity causes the door slab and frame to expand. If the roof cap was installed without proper clearance or the jamb has settled, the top right or left corner of the door starts dragging in July and August. It’s not the door warping; it’s the frame moving. We reset the frame and re-hang the cap with proper reveal so it closes clean year-round. Call (754) 310-3589 for a free estimate.
Because we’re a multi-brand shop serving Fort Lauderdale with authorized lines including PGT, CGI, CWS, and ES Windows, we maintain a broader local inventory than a single-brand dealer typically does. For Therma-Tru specifically, we order the correct OEM profile when the original is available and use a quality aftermarket profile when it’s not. We tell you which you’re getting and why before we start.
A roof cap replacement runs $220 to $480. A cap with top rail repair runs $480 to $900. A full roof assembly replacement runs $900 to $1,600, and a complete Therma-Tru door replacement with new roof assembly runs $1,400 to $3,200. Every quote is fixed and line-itemed before work begins. Call (754) 310-3589 for an exact price on your door.
