AfterPGT Roof Replacement & Installation in Miami: What to Know First
PGT roof replacement and installation in Miami runs $18,000 to $42,000 for a standard single-family home, depending on roof size, slope, and whether you’re adding or upgrading the PGT impact-rated underlayment and flashing systems that Miami-Dade code requires. Most full replacements take 3 to 7 working days once materials are on site. TruePane Windows & Doors is an independent PGT service provider, not a manufacturer affiliate, and we price this work with a written line-item estimate before anything gets torn off.
This page is for homeowners in Miami who already have PGT windows, doors, or skylights and need a roof replacement or new installation that won’t compromise the impact rating they paid for. If you’re trying to sort out whether your roofer actually understands PGT product integration, call (754) 238-2201 and ask for Dale. We’ll tell you straight what’s involved.
How PGT Products Fail - and How We Fix Them
PGT builds a solid impact-rated product, but a roof replacement is exactly the moment when installation shortcuts from years past show up. Here’s what we see in Miami homes:
- PGT WinGuard windows with failed roof flashing above the header. The window itself is fine; the problem is the original roofer sealed the top flange with caulk instead of a proper step flashing. Water tracks behind the stucco, rots the lintel, and the homeowner blames the window. We pull the header trim, install code-correct flashing, and reset the window so the water actually sheds.
- PGT SkyView skylights leaking at the curb mount after a re-roof. Roofers who don’t know better lay new shingles right up to the old curb and reuse the original gasket. In Miami’s afternoon downpours, that gasket is already half-cooked from ten years of direct sun. We replace the curb flashing and gasket as a unit, then tie the new roofing into it the way PGT’s install spec calls for.
- PGT ClassicVue picture windows with bowed frames from a roof-load shift. Older Miami homes with tile roofs settle, and when the roof plane sags even a quarter inch it transfers pressure onto the window frame below. The window binds, or worse, the insulated glass unit cracks at the corner. We shim and square the rough opening before installing the new window, so the new unit isn’t fighting the house from day one.
- PGT aluminum frame corrosion at the roof-line transom. We see this most in homes within a mile of Biscayne Bay or the Miami River. Salt air eats the factory finish around the weep holes first, then the frame itself. If the glazing is still sound, we can sometimes restore and reseal; if the frame’s gone soft, it’s a full replacement with a properly flashed new unit.
- PGT sliding glass doors that bind after the roof deck is replaced. This shows up within weeks of a new roof. The new decking changes the load path slightly, and a door that slid fine for fifteen years starts dragging. We re-level and re-set the door track, and if the header has moved, we correct that before it cracks the glass in the door panel.
Our PGT Roof Replacement & Installation Process
Every job follows the same order, because skipping a step is how you end up back on the roof in August:
- 1
On-site measurement and inspection. Dale measures every opening himself. We check the rough opening, the header, the existing flashing, and the condition of any PGT glass we’re working around. If the pane is not true, the job is not done.
- 2
Written, side-by-side quote. We put PGT pricing on paper next to comparable lines (CGI, CWS, ES Windows, ECO Window Systems) so you see exactly what you’re paying for and why.
- 3
Materials ordered and verified. For PGT work, we confirm series, size, glass package, and impact rating before anything ships. Wrong glass in a Miami impact zone means a reorder and a delay you shouldn’t have to eat.
- 4
Tear-off and deck inspection. If the roof deck has rot or the framing has shifted, we fix that before new PGT units go in. No point installing straight product into a crooked house.
- 5
Installation, flashing, and sealing. Every PGT unit set true, flashed to Miami-Dade code, and sealed with products rated for our humidity and salt air.
- 6
Test and walkthrough. We operate every unit, check the seals, verify drainage, and walk you through what was installed and why. Then we register both warranty layers in writing before the truck leaves.
What PGT Roof Replacement & Installation Costs in Miami
Straight numbers, because you deserve them before anyone starts swinging a hammer:
- Full roof replacement with PGT-compatible flashing and underlayment: $18,000-$42,000, depending on square footage, slope, and tear-off layers
- PGT SkyView skylight replacement with new curb flashing: $1,800-$3,600 per unit
- PGT WinGuard window replacement with header flashing correction: $850-$1,700 per window
- PGT sliding glass door re-set and re-flash at roof line: $600-$1,400
- Roof-line transom restoration or replacement: $700-$2,200 depending on frame condition
What moves the price: roof pitch (anything over 6/12 runs higher), decking that needs full replacement, hidden rot behind stucco, and whether your existing PGT units are still under warranty. Call (754) 238-2201 for a free estimate with line-item pricing, no surprises on the bill.
Why Miami Homeowners Call TruePane Windows & Doors for PGT Work
We’ve served Miami and nearby communities since 2008 through Dale Kessler’s craft tradition, and we’ve never been the cheapest bid in the room. That’s intentional. The Keystone Standard means both warranty layers registered in writing and durations stated before the truck leaves your driveway. The Done Right Promise means if it’s not right, we make it right, no paperwork fights and no arguing. We install more than a dozen manufacturer lines including PGT, CGI, CWS, ES Windows, and ECO Window Systems, so we’re never forcing one brand because we bought too much inventory. When a homeowner needs straight answers about whether their PGT product survives a re-roof, we give them a square deal and stand behind it.
FAQs
No, a roof replacement by itself doesn’t void a PGT window or door warranty, but improper flashing or installation around the PGT unit can. That’s why we re-flash every opening to code when we do a Miami roof replacement. Call (754) 238-2201 and we’ll tell you whether your existing PGT units are at risk before the roofer starts.
Yes, and it’s actually the smartest time to do it. The roof is open, the rough openings are exposed, and we can correct structural issues while installing new PGT units. It saves you a second tear-off down the road.
Most full replacements run 3 to 7 working days once materials are on site, barring weather delays or hidden deck damage. Miami’s afternoon storms can stretch a schedule, so we build that into the timeline rather than promising a date we can’t keep.
We use PGT factory parts when they’re available and the right fit, and quality aftermarket components when the factory spec won’t hold up to Miami conditions or the part’s been discontinued for an older series. We show you the difference in writing before we order.
It can, but only if we find hidden rot, termite damage, or structural issues that weren’t visible before tear-off. If that happens, we stop work, show you what we found, and give you the revised number in writing before we proceed. No surprise line items on the final bill.
