Therma-Tru Shingle, Tile & Metal Roofing in Hialeah: What to Know First
We perform independent Therma-Tru shingle, tile, and metal roofing repair and replacement throughout Hialeah, and most jobs are quoted within 24 hours of your call. Typical repairs run $225 to $1,100, while full roofing projects involving Therma-Tru door or window flashing integration start around $4,500 and climb based on square footage and material choice. This page is for Hialeah homeowners who already own a Therma-Tru product or are planning a roofing project around one, and who want a straight answer about cost, process, and what actually fails. Call (850) 998-3090 and you’ll get Ed Winslow’s team on the line, not a call center.

How Therma-Tru Products Fail - and How We Fix Them
Therma-Tru builds solid doors and windows, but in Hialeah’s heat, humidity, and hurricane-season rain, we see the same few failure points over and over. Here’s what actually shows up in the field:
- Flashing separation at the head of Therma-Tru entry doors under tile roofs. On Hialeah’s older concrete-block homes with barrel-tile roofs, the step flashing above a Therma-Tru entry door often gets pried up during tile replacement. Water tracks down the door frame, rots the jamb from the inside, and the homeowner doesn’t notice until the door sticks. We pull the affected tiles, replace the flashing with proper step-flashing tied into the underlayment, and reseal the frame joint. The door itself usually survives.
- Sill-pan failures on Therma-Tru sliding patio doors under flat metal roofs. Hialeah has thousands of flat or low-slope metal roofs, and when the roof drains toward a patio door, the sill pan takes a beating. We see Therma-Tru sliding doors where the sill pan was never properly sloped, so standing water backs up and wicks under the threshold. The fix is pulling the door, re-panning with sealed corners, and re-flashing the roof-to-door transition. If the door’s bottom rail has swelled, we can often salvage it with a sash replacement instead of a full door swap.
- Buck and frame distortion on Therma-Tru fiberglass frames adjacent to metal roof expansion seams. Metal expands hard in South Florida sun. When a roof panel seam sits directly above a Therma-Tru frame, repeated thermal cycling can loosen the frame anchors and cause the operable panel to sag. We re-anchor the frame with longer fasteners into the block, then re-shim and re-level the door so it closes square again.
- Caulk joint failure around Therma-Tru transom and sidelight assemblies on shingle-roofed lanai conversions. In Westland and the older sections of Hialeah, lanai enclosures built in the 1980s and 90s often paired a Therma-Tru door with a transom or sidelights. The original caulk joints between frame and stucco crack, shingle runoff funnels into the gap, and you get slow leaks that stain interior drywall. We cut out the old sealant, install backer rod, and use a high-adhesion polyurethane sealant rated for Hialeah’s wet-dry cycle. This one’s common enough that we check it on every Therma-Tru call even when the homeowner called about something else.
- Threshold corrosion on Therma-Tru doors under tile roofs with valley runoff. Clay and concrete tile valleys concentrate water. When the valley terminates near an exterior door, the splash pattern corrodes aluminum thresholds faster than anywhere else on the home. We replace the threshold with a higher-profile model and add a small diverter to kick water away from the door. It’s a $180 to $300 fix that prevents a $1,500 door replacement later.
Our Therma-Tru Shingle, Tile & Metal Roofing Process
Every Therma-Tru job in Hialeah follows the same sequence, whether it’s a repair or a full roofing integration:
- 1
You call (850) 998-3090. A real person answers, takes your address and the basic issue, and schedules a walkthrough. No voicemail loops.
- 2
We inspect the Therma-Tru product and the roof together. Roofing and door or window failures are usually connected, so we don’t look at one without checking the other. Ed’s background in window work means he catches things a roofing-only crew misses.
- 3
We give you a written, line-item repair or replacement plan. We tell you whether OEM Therma-Tru parts make sense for your situation, and where a quality aftermarket component performs just as well for less money. No mystery charges later.
- 4
We do the work and pull permits when the scope requires it. Larger roofing integrations in Hialeah need city permits, and we handle that side of it. Inspections pass before we call the job done.
- 5
We test the repair in front of you. If water was involved, we run water over the flashed area while you watch. You see the fix work before we pack up.
- 6
We stand behind it under the Done Right Promise. If it’s not done right, we make it right. That’s the whole promise.

FAQs
No, because we’re an independent Therma-Tru service provider and we use either OEM parts or quality aftermarket parts that don’t alter the structural assembly. We never modify frame construction or drill through weatherstripping channels. If you have an active warranty claim, we’ll document the repair with photos so you have what you need. Call (850) 998-3090 and we’ll walk you through it.
Common parts like thresholds, weatherstripping, and adjustable sills are usually available same-week through local supply houses. Custom glass or full-door replacements for Therma-Tru products typically take two to four weeks. We’ll tell you upfront which category your job falls into before you commit to anything.
Almost never. In our Hialeah service area, most leaks around Therma-Tru doors come from failed flashing or caulk joints, not from the door itself. We repair the transition between roof and frame first, and only recommend a new door if the frame has rotted or warped beyond a safe seal. You’ll see the testing before we leave.
Yes. Tile roofs require careful handling around any wall or door penetration, and we use hand tools rather than full-size saws in those zones. Every Therma-Tru frame adjacent to the work area gets masked and protected before we start. It’s standard procedure on our crew.
We permanently offer $40 off any repair over $200, a free second opinion on any written estimate, no trip charge inside our home county, and a 10% discount for seniors and veterans. These aren’t seasonal. They’ve been standing since the day we opened. Call (850) 998-3090 and mention which one applies to you.
