Therma-Tru Roof Repair in Miami: What to Know First
Therma-Tru roof repair in Miami is work we handle as an independent Therma-Tru service provider, and most jobs are diagnosed and repaired in a single visit once parts are confirmed. We’re not going to quote you a price over the phone without seeing the damage, because nobody honest does that, but we will give you a written, line-item estimate before any work begins and the number on that estimate is the number you pay. If you own a Therma-Tru door or window assembly that’s failed at the roofline, or a Therma-Tru skylight flashing that’s letting water into your soffit, call (863) 946-5039 and a real person picks up. Ed Winslow’s name is on the door, and on every repair we do in Miami.
How Therma-Tru Products Fail - and How We Fix Them
Therma-Tru builds doors and entry systems, so when we talk about roof repair on a Therma-Tru product in Miami, we’re almost always talking about the intersection where the product meets the roofline: flashing, head jamb caps, eyebrow overhangs, transom windows, and the drip edge that protects them. Here’s what we actually see in Miami homes:
- Leaking transoms and arched eyebrow windows over entry doors. The Therma-Tru Classic-Craft and Fiber-Classic lines often ship with arched transoms or eyebrow assemblies above the door unit. In Miami’s afternoon downpours, if the flashing above that eyebrow wasn’t lapped under the roof’s second course of shingles, or the kickout flashing at each end is missing, water runs straight into the head jamb. We see it all the time. Our fix: remove the top cladding, re-lap the flashing properly, install new drip edge, and reseal with a Miami-rated polyurethane caulk that holds up under UV.
- Fascia rot above Tru-Defense door systems. The Tru-Defense series has a multi-point lock system and composite jambs, good product. But if the roof drip edge over that door can’t handle wind-blown rain, the fascia board above it soaks every time a squall comes through, and then the rot migrates into the head cap trim. We replace the fascia, correct the drip edge overhang, and usually save the door itself.
- Sun-degraded flashing tape and sealant on older Smooth-Star installations. Therma-Tru’s Smooth-Star line has been around long enough in Miami that we’ll see units from fifteen or even twenty years back. The door is fine. The flashing tape above it isn’t. That old builder-grade tape bakes on a south-facing elevation, turns brittle, and separates. We strip it, inspect the sheathing under the roofline, repair any water damage, and re-flash with butyl-based peel-and-stick that won’t harden the same way.
- Drip-edge rust and separation over Therma-Tru sliding patio doors. South Miami salt air is rough on painted steel drip edge. Over slab door units, especially the Therma-Tru 380 series sliding glass door, a rusted drip edge lets water track behind the stucco and wick down into the door header. Some companies will just caulk over it. That fails in six months. We cut out the rusted section, replace it with aluminum, and make sure the offset actually directs water out past the door cap, not behind it.
- Ponding and roof-induced header sag. If the roof framing above a Therma-Tru entry has settled, or the roof valley dumps too much water right over the door, the header can sag a fraction and crack the head jamb seal. That’s when a door “leak” is really a roof problem. We inspect the roof above first, not the door first, because in Miami it’s usually the roof drainage that’s the root cause. Fix the roof, then the door works the way it was designed to.
Our Therma-Tru Roof Repair Process
- 1
You call (863) 946-5039. A person answers, no phone tree. We ask what you’re seeing: water streaks, dripping from the head jamb, paint bubbling above the door, wet drywall near the roofline.
- 2
We inspect. We look at the roof edge above the Therma-Tru unit first, then the flashing, then the door or window itself. Half the time the door isn’t the real problem and we tell you that straight, because we’d rather do the repair that actually fixes it than the one that just bills a number.
- 3
We give you a written estimate. Line-item, in plain English. If it is over $200, you get $40 off. If you already have a written estimate from another company, we’ll give you a free second opinion on it.
- 4
We do the repair. OEM Therma-Tru trim and components where it matters for fit, quality aftermarket flashing and sealants where it’s the better product. We’ll tell you when we’re using which and why.
- 5
We test with water. On a dry day, we run water over the repair area slowly and watch. If it leaks, it’s not done. Most repairs don’t leak when we’re done, but if anything ever fails, the 36500-Day Done Right Promise means we make it right.
- 6
We clean up and walk you through what we did. You see the same photos we see, and Ed Winslow stands behind the work.
What Therma-Tru Roof Repair Costs in Miami
Honest numbers for Miami, based on what we see across roof-to-door repairs:
- Simple flashing re-seal above a Therma-Tru entry door: $180-$320. This is the most common repair, and it’s the one other companies either skip or overcharge for.
- Drip edge replacement over a Therma-Tru door or transom: $250-$450, depending on how much rusted steel has to come out and whether fascia repair is involved.
- Eyebrow/transom re-flash with kickout flashing, both ends: $400-$700. This is the fix that actually stops the recurring leak when the roof just won’t shed water cleanly over the door.
- Full fascia and header repair above a Therma-Tru unit: $600-$1,200. You’ll see this range when Miami’s wet season has been doing its work for a few years and the rot has had time to set in.
What moves the price: whether we need to cut back stucco or siding, whether the roof itself has a drainage problem that needs correcting at the same time, and whether the door or window unit itself has been compromised. Call (863) 946-5039 for a free estimate, and we’ll tell you the exact number before any work begins.

FAQs
No, not the way we do it. Independent Therma-Tru service providers can perform roof repair and flashing work around a Therma-Tru door or transom without voiding the unit’s own warranty, as long as the door itself isn’t modified and the roof work doesn’t alter the door’s structural framing. We’re careful about that line, and we’ll tell you if a repair you’re asking about could touch the warranty.
In Miami, nine times out of ten that’s a roof drainage or flashing issue above the door, not the door itself. Rain gets behind the drip edge, runs down the fascia, and enters at the head jamb. We trace it from the roof edge down, because fixing the door seal won’t fix the water coming from above. Call (863) 946-5039 and we’ll find the actual source.
If the repair is straightforward and we have the flashing or sealant on the truck, often yes. For rotted fascia or a full eyebrow re-flash, we’ll schedule the next available slot, and we’ll give you a live-person answer on the phone right now about what we’re seeing in the calendar for Miami this week.
When the repair touches a visible Therma-Tru trim piece or cap, we use OEM so the finish matches and the fit is right. For hidden flashing components, we choose based on what’s actually the better product for Miami’s salt air and UV. We’ll tell you which is which on your written estimate.
Most flashing and drip-edge repairs run $180 to $700, and full fascia replacement can run $600 to $1,200. The only way to give you a real number for your roof repair is to look at it, which we’ll do for free. Call (863) 946-5039 for a free estimate, and remember the $40 off any repair over $200, plus the 10% discount for seniors and veterans.
