This page is for homeowners who own Therma-Tru doors and are dealing with roof repair issues around them: water intrusion at the threshold, flashing failures, rot in the substrate, or seal breakdowns after a Boca Raton storm. You want to know what’s actually wrong, what it costs, and whether the fix will hold. That’s what we cover here.

How Therma-Tru Products Fail - and How We Fix Them

Therma-Tru builds a genuinely tough door, but roof repair around these units has failure patterns we see over and over in Boca Raton. Here are the five most common ones, with the real cause and how we address it.

• Sill pan movement on Classic-Craft units under covered entries. We see this regularly in older Boca Raton homes where a covered porch meets the main roof. The Therma-Tru Classic-Craft sill pan sits below a roof slope that channels water directly at the door. Over years of South Florida rain, the pan shifts a few millimeters. That’s enough to break the seal. We remove the door, reset the pan with proper slope, reflash, and remount. It’s a full-day job on most units.
• Rot in the sub-sill beneath Fiber-Classic doors after prolonged gutter overflow. This one surprises people. The Fiber-Classic door slab itself won’t rot; it’s fiberglass. But the wooden sub-sill underneath it will if the gutter above the entry dumps water onto the door for years. We pull the door, cut out the rotted sub-sill, replace it with pressure-treated stock, install a proper drip edge, and remount the door. The door slab is almost always fine.
• Warped hinge-side jamb on Smooth-Star doors caused by reflected heat from a nearby roof valley. Boca Raton sun is relentless. When a roof valley reflects afternoon heat onto a Smooth-Star door’s hinge jamb, the composite can bow just enough to break the weather seal at the top corner. We replace the jamb leg, shim the frame straight, and often recommend a small awning or deflector to keep direct heat off the door. It’s a heat problem, not a door defect.
• Flashing separation where a Marquis door sits under a flat-roof overhang. We catch this one on mid-century and 1980s homes along Federal Highway. The original installer lapped the roof membrane over the door flashing, and the membrane has since pulled back. Water runs behind the flashing and into the wall. We remove the old flashing, run new membrane up the wall, and reflash the door properly. This is roof repair as much as door repair.
• Threshold seal degradation on Therma-Tru multi-point locking systems after salt-air exposure. Boca Raton’s salt air is hard on rubber and silicone. The adjustable threshold seal on multi-point doors hardens and shrinks in three to five years near the coast. Water seeps under the door. We replace the seal with a marine-grade alternative and adjust the multi-point lock so the door seats firmly against it. The fix takes under two hours.

Our Therma-Tru Roof Repair Process

1. 1
   You call, a person answers. Day or night, a real person picks up the phone. No call centers. We set a time that works for you, and we show up when we say we will.
2. 2
   We diagnose the actual problem. Ed or one of our senior techs walks the roofline, checks the flashing, and examines the door frame, sill, and threshold. We explain what we find in plain English before any work begins.
3. 3
   You get a fixed written quote. We tell you exactly what it costs. No change orders later. If you already have a written estimate from another contractor, bring it. We’ll give you a free second opinion.
4. 4
   Parts decision: OEM or quality aftermarket. We use Therma-Tru OEM parts when the door is under warranty or when the part is integral to the system (multi-point locks, corner seals). For non-warranty items like sub-sills, flashing, and threshold seals, we often recommend higher-grade aftermarket materials because they outlast the originals in Boca Raton’s salt air and sun.
5. 5
   We do the repair and test it. We run a full water test on the repaired area before we pack up. If water gets through, we’re not done.
6. 6
   We clean up and explain the work. You see what we did, why we did it, and what to watch for going forward. Then Ed’s name is on the job, and so is the 36500-Day Done Right Promise.
