Therma-Tru Roof Replacement & Installation in Miami Beach: What to Know First
Therma-Tru roof replacement and installation in Miami Beach typically runs $1,800 to $6,400 depending on the door configuration, glass package, and whether the existing frame is salvageable. We complete most Therma-Tru roof jobs in a single visit, and we quote a fixed price before any work begins. If you own a Therma-Tru roof window or roof door that’s failing, this page tells you what we see in Miami Beach, what it costs to fix, and how we handle the work.
This page is for homeowners who bought a Therma-Tru product and need it replaced or properly installed. We are an independent Therma-Tru service provider, not a factory-authorized dealer. That means we call problems the way we see them. Call (386) 406-9359 and a person answers, 24 hours a day.
How Therma-Tru Products Fail - and How We Fix Them
Therma-Tru makes solid fiberglass and steel entry systems, and their roof lines include the Pulse, Classic-Craft, and Smooth-Star series with transom and sidelight configurations that roof into open entries. In Miami Beach, the salt air and hurricane-driven rain expose weaknesses that a showroom in Ohio never sees. Here’s what we find:
- Classic-Craft roof transom seal failure at the header. The multi-point locking system on Classic-Craft is solid, but the roof transom above it relies on a compression gasket that shrinks in the salt air. Water wicks in at the top corners, the interior veneer swells, and the homeowner sees staining on the drywall before they see any drip. We pull the transom, replace the gasket with a marine-grade seal, and reset the flashing so water sheds instead of pooling.
- Pulse series roof-door hinge sag. The Pulse line uses adjustable hinges, but after six or seven years of Miami Beach humidity cycles, the hinge screws lose bite in the fiberglass jamb. The door drops, the roof sweep drags, and the panel binds on the hinge side. We drill and epoxy-fill the screw holes, reset the hinge geometry, and re-hang the panel to factory reveal tolerances.
- Smooth-Star roof window frame rot at the sill. Smooth-Star is a fiberglass skin over a wood core, and the roof window version has a sill that catches standing water after a coastal downpour. Once the sill cap develops a hairline crack, water reaches the wood core and the rot starts. We replace the sill with a composite option that does not absorb water, then seal the roof flashing with a polyurethane caulk rated for 50-year UV exposure.
- Weatherstrip compression set on all roof models. Therma-Tru uses a Q-Lon weatherstrip that works well in dry climates. In Miami Beach, the combination of heat and salt causes it to take a permanent set within four years, especially on west-facing exposures. The roof leaks air, the AC bill climbs, and the door sounds hollow when it shuts. We replace it with a wider-profile bulb seal and adjust the strike plates so the compression is even across the whole leaf.
- Roof flashing failures after storm-driven rain. The factory flashing kit depends on a roof pitch that most Miami Beach homes do not have. Flat roofs and low-slope entries let water run toward the door instead of away from it. We see this constantly on Art Deco and mid-century builds from North Beach to South of Fifth. Our fix is a custom-bent flashing with a taller back dam and a drip edge that directs water to the sides, not the threshold.
Our Therma-Tru Roof Replacement & Installation Process
- 1
Call and talk to a person. You call (386) 406-9359. A live person answers and schedules a time that works for you. No callback forms, no voicemail tree.
- 2
We measure the opening twice. A background-checked, uniformed technician arrives, pulls the interior casing, and reads the rough opening with a 6-foot level and a tape. If the opening is out of square, we know before we order a single part.
- 3
We show you the options on paper. OEM Therma-Tru parts alongside quality aftermarket alternatives, with prices written down. You decide. We do not surprise you with a change order at the end.
- 4
We do the work in one visit. The old unit comes out, the new roof panel or window goes in, and we re-flash, shim, seal, and set every fastener to spec. If the opening is not true, we fix the opening before we set the panel.
- 5
We test it in front of you. Door swings level, roof seals tight, locks engage. We run a water test on the roof flashing and show you the result.
- 6
We register the warranty and clean up. Both manufacturer warranty layers get registered in writing, with durations stated, before the truck leaves the driveway. The job site is broom-clean. The Done Right Promise covers the workmanship.

That’s the standard we bring to every Therma-Tru job.

FAQs
No, replacing a failed Therma-Tru roof window through an independent provider does not void the manufacturer warranty on the rest of the entry system, provided the installation meets the manufacturer’s flashing and sealing requirements. We follow Therma-Tru’s published installation specs and register the new product warranty in writing before we leave. Call (386) 406-9359 and we will walk you through what is covered on your specific unit.
Most Therma-Tru roof door replacements are completed in a single visit, typically 4 to 6 hours on site. We stock common Smooth-Star and Pulse hardware locally, and we order exact-pattern Classic-Craft panels with a short lead time. Call (386) 406-9359 and we will tell you what is available for your model right now.
If the fiberglass skin is intact and the failure is weatherstrip, hardware, or flashing, repair makes sense and costs less. If the wood core has absorbed moisture or the roof panel is delaminating, replacement is the honest call. We will show you both options on paper with prices and let you decide. Call (386) 406-9359 to schedule a look.
We quote OEM Therma-Tru parts alongside quality aftermarket options on every job, with prices written down. OEM is the safer choice for warranty continuity on newer units. On older roofs where the OEM part is discontinued, a marine-grade aftermarket component often outperforms the original. You get to see the difference in writing before you spend a dollar. Call (386) 406-9359 and we will explain what fits your unit.
A properly flashed and sealed Therma-Tru roof door or window in Miami Beach should give you 15 to 25 years of service before needing major work. The roof flashing and weatherstrip will need attention every 4 to 6 years because of the salt air. We stand behind the workmanship with the Done Right Promise, and we register the manufacturer warranty so you know exactly what is covered and for how long. Call (386) 406-9359 for a free estimate.
