AfterTherma-Tru Roof Replacement & Installation in Miami Beach: What to Know First
Therma-Tru roof replacement and installation in Miami Beach typically runs from $12,000 to $38,000 depending on roof size, pitch, and whether you’re dealing with the original decking or moisture damage underneath. Most full replacements on single-family homes near North Beach and mid-Miami Beach take five to seven working days once materials land, and we give you a written line-item quote before the first shingle comes off. That quote doesn’t change unless we uncover something structural that requires a permit revision, and we’ll walk you through that in person before any additional work happens.
If you own a Therma-Tru door or window and now need roof work, you’ve already learned what Miami Beach salt air and hurricane season do to exterior products. The same standards that make Therma-Tru entry systems worth the investment apply to the roof above them, and that’s where we come in. As an independent Therma-Tru service provider, we’re not beholden to a manufacturer’s script, and we’re not a franchise with a rotating crew. Call (863) 656-0462 and you’ll get a real person who knows Miami Beach roofing, not a call center.
How Therma-Tru Products Fail - and How We Fix Them
Therma-Tru makes entry doors and door systems, not roofing shingles or underlayment. So when we talk about Therma-Tru roof replacement in Miami Beach, we’re talking about the intersection where the roof meets the door system: the threshold, the flashing above the door, the sidelight seals, and the way water moves off the roof plane and past your entryway. Here’s what we actually see on Miami Beach homes.
- Flashing failure above Therma-Tru Classic-Craft doors. The Classic-Craft line uses a composite door slab that holds up beautifully, but the roof flashing above it is only as good as the last installer’s attention to detail. We routinely pull back shingles over covered entries on Collins Avenue and find step flashing that was nailed too low or sealed with caulk instead of proper metal-to-metal laps. Water creeps behind the flashing, runs down the door frame, and rots the rough opening. Our fix: strip back the roof edge, install proper step flashing with a kickout diverter, and re-bed the Therma-Tru frame with a sill pan that actually drains.
- Sidelight rot from roof runoff on Therma-Tru Smooth-Star systems. Smooth-Star fiberglass doors are nearly indestructible, but the sidelight frames around them are often wood, and Miami Beach’s rainy season sends roof runoff straight down onto them when gutters are undersized or missing. We see this constantly on 1920s and 1930s homes in the Flamingo Park area. The fix isn’t just replacing the sidelight frame. It’s correcting the roof edge so water kicks away from the entry, then reinstalling the Smooth-Star slab with a properly sloped threshold.
- Threshold heaving on slab foundations near the beach. Miami Beach sits on sand and limestone, and homes within a few blocks of the ocean move. When a concrete slab shifts even a quarter inch, a Therma-Tru threshold can lift just enough to let wind-driven rain under the door. We’ve fixed this on condos near the Faena District where the door itself was fine but the slab had settled. The roof connection matters here too: if roof drainage isn’t moving water away from the foundation line, the slab movement gets worse. We address both.
- Wind-driven rain intrusion through Therma-Tru door-to-roof transitions on flat-roof homes. A lot of Miami Beach homes have flat or low-slope roofs with roof deck drains. When a Therma-Tru door sits at roof level, like on a rooftop terrace or an upstairs balcony entry, the door’s top cap and the roof membrane have to work as one system. We’ve seen silicone smeared over failed TPO seams above door heads, which works for a season and then fails during a September storm. The real fix is membrane-to-door flashing done by someone who understands both the roofing membrane and the Therma-Tru frame geometry.
- Improper aftermarket weatherstripping on Therma-Tru doors after roof work. Roofers who don’t know doors will yank door weatherstripping to get shingles past the entry, then shove it back in place. On Therma-Tru doors, the compression seal and sweep are matched to the door’s specific profile. Aftermarket generics from a big-box store don’t compress the same way, and you end up with daylight under the door. We keep Therma-Tru-compatible seal profiles on our trucks for exactly this reason.
Our Therma-Tru Roof Replacement & Installation Process
- 1
The call and the questions. You reach a live person at (863) 656-0462. We ask about your home’s age, roof type, and whether any water has ever appeared around your Therma-Tru entry. Then we schedule a site visit.
- 2
The inspection. We walk the roof, check the decking from the attic if there’s access, and put eyes on every place the roof plane touches a Therma-Tru door, sidelight, or threshold. We photograph everything and show you what we found.
- 3
The written quote. You get line items, not a lump sum. Tear-off, decking replacement if needed, underlayment, roofing material, flashing, door-to-roof integration, and cleanup are listed separately. The price we quote is the price you pay unless we find something structural.
- 4
Parts decision. For the Therma-Tru components, we use factory-matched profiles from Therma-Tru’s parts network or quality equivalents that meet the same tolerances. We’ll tell you the difference and let you choose. Nothing is hidden.
- 5
The work. Our crew, background-checked and in uniform, does the tear-off, decking repair, underlayment, roofing, and the door-to-roof flashing work as one continuous job. No subcontractor roulette. The same crew that touches the roof touches your Therma-Tru entry.
- 6
The test and the walkthrough. We run water over every flashing point, check the door from both sides, and walk you through what we did before we leave. If anything isn’t right, the 36500-Day Done Right Promise means we come back and make it right.
What Therma-Tru Roof Replacement & Installation Costs in Miami Beach
Here’s what we’re seeing in Miami Beach in 2025, current costs, not national averages:
- Full roof replacement on a 1,200-1,600 sq ft single-family home, including tear-off and standard architectural shingles: $14,000 to $22,000
- Same home with tile or standing-seam metal roof: $26,000 to $38,000
- Therma-Tru door-to-roof flashing replacement with new step flashing, kickout diverter, and sill pan (no full roof replacement): $900 to $2,400 depending on access and how much rotted framing needs repair
- Adding a Therma-Tru entry door to a roof replacement job where the existing door is salvageable: $500 to $1,800 for flashing, sealing, and threshold reset
- Roof decking repair discovered during tear-off: $85 to $140 per sheet installed, and we show you the rot before we touch it
What moves the price in Miami Beach: roof pitch and access (two-story flat-roof homes near the bay need more staging), whether your decking is true 1x boards or plywood, and how much salt-air corrosion is already in the flashing.

Why Miami Beach Homeowners Call Winslow Windows & Doors for Therma-Tru Work
Ed Winslow grew up in Miami and has spent nearly three decades figuring out what South Florida’s climate does to poorly installed windows, doors, and roofs. He picked up the fundamentals at Miami Dade College’s Building Construction Technology program, then spent years in the field before putting his own name on a truck. You can check our published address and license number anytime. No shell companies, no ticket numbers.
We started in 2011, and a lot of our Miami Beach work comes from repeat customers. One year it’s impact windows. Three years later it’s a roof. Five years after that it’s a Therma-Tru door that needs flashing corrected after a storm. Being a full exterior-protection company means we see how all the pieces interact, which is exactly what you need when a roof and a door system have to work together. We also install PGT, CGI, CWS, and ES Windows products, so when your roof job turns into a window conversation, you’re already talking to the right crew. My name is on every job we do. That keeps me honest.
FAQs
No, as long as the roof work doesn’t damage the door system and the door isn’t modified. Therma-Tru warranties cover the door and its components, not the roof above it, but a sloppy roof job that leaves the door flashing leaking can cause damage that Therma-Tru won’t cover. We document the door’s condition before and after roof work so your warranty position stays intact. Call (863) 656-0462 and we’ll explain what we protect and how.
Most common Therma-Tru parts, sweep seals, compression gaskets, sill caps, and frame components, are in stock at our local suppliers or on our trucks. Unusual items or special-order sizes usually arrive within five to ten business days. We won’t hold up a roof replacement waiting on a door part unless the two jobs are structurally connected, and if they are, we’ll tell you upfront.
Only if the door has real problems: rot in the frame, a failed threshold, or wind-driven water getting past the seals during storms. If the door itself is sound, the right move is to do the roof properly and re-flash the door-to-roof transition at the same time. That’s the part most roofers skip, and it’s the part that keeps water out of your entry for decades. Call (863) 656-0462 for an honest assessment, we’ll tell you if your door can stay.
It’s our word that if the work isn’t done right, we make it right. One hundred years. Ed’s name is on the door, and on every job we do. No fine print, no prorated nonsense, no arguing about whose fault it was. If it’s our work and it fails, we fix it.
Yes. Miami Beach has specific code requirements for roofing, including wind mitigation and hurricane strapping standards, and we pull all required permits and schedule inspections. We don’t cut corners with the building department, and we don’t ask you to. The permit is part of the job, not an add-on expense you discover later.
If your Therma-Tru entry and your roof need to work as one system, call (863) 656-0462 and ask for Ed. You’ll get a free estimate, written in plain English, from a company that’s been doing this in Miami Beach for over a decade. The one down the road.
