PGT Roof Replacement & Installation in Miami Beach: What to Know First
PGT roof replacement and installation in Miami Beach typically runs $14,500 to $38,000 depending on roof size, pitch, and whether you’re going with architectural shingles, metal, or tile. We’re an independent PGT service provider, which means we work on PGT-fitted homes throughout Miami Beach but we answer to you, not a manufacturer. Most full replacements take 3 to 7 working days once materials land. If you’re seeing ceiling stains, lifted flashing, or granule loss around skylight curbs, call us at (863) 656-0462 for a free estimate. This page is for Miami Beach homeowners who own PGT impact windows and doors and need a roofing crew that understands how those systems tie together.
How PGT Products Fail - and How We Fix Them
PGT windows and doors are built for hurricane country. But your roof is the first line of defense, and when it fails, it drags PGT products down with it. Here’s what we see on Miami Beach roofs that sit above PGT openings:
- Leaks at the window-to-roof transition on PGT WinGuard casement installs. On second-story dormers and eyebrow windows, flashing fails before the window does. Water sneaks behind the nailing flange, runs down the interior wall, and the homeowner blames the window. We pull the shingles, replace the step flashing and peel-and-stick underlayment, and reseat the window trim. The WinGuard unit itself usually passes our water test afterward.
- Skylight curb rot around PGT SpectraView and Picture Window sightlines. Miami Beach humidity plus original 1990s curb construction equals soft wood. Water pools at the curb corners, saturates the sheathing, and the PGT window below starts showing condensation between panes. We rebuild the curb with pressure-treated lumber, wrap it in self-adhered membrane, and flash it before reinstalling the skylight.
- Chimney chase leaks staining PGT sliding glass door headers. We see this on Collins Avenue condos and older single-family homes near North Beach. The chase cap corrodes, water travels down the framing, and the first visible sign is bubbling drywall above a PGT SGD860 slider. The roof replacement includes a new stainless cap and full chase flashing. The slider almost never needs replacement.
- Valley failure above PGT fixed windows on flat-roof sections. Miami Beach has plenty of mixed roof profiles: tile over the main structure, modified bitumen over additions. Where those surfaces meet at a valley, the material transition is a weak point. Water finds the seam, drips onto ceiling drywall above PGT fixed picture windows in sunrooms. We install closed valleys with adhesive underlayment and metal valley liners that shed water away from glazing.
- Wind-driven rain entry at PGT French door transoms. This one’s common in Miami Beach homes built just after Hurricane Andrew. Roof decking pulls loose at the soffit line during storms, breaking the seal where roof meets wall. Rain follows the fascia into the transom framing above PGT French doors. We re-secure the decking, replace the drip edge, and seal the eave-to-wall joint before laying new roofing.
Our PGT Roof Replacement & Installation Process
A PGT-home roof replacement in Miami Beach follows a sequence. Here’s what we do, start to finish:
- 1
Site walk and roof measurement. Ed or a lead tech walks the roof, checks the condition around every PGT opening, and photographs the flashing, penetrations, and valleys. You get a line-item written quote, not a round number.
- 2
Material and underlayment decision. We match your existing profile: shingle, tile, or metal. We recommend peel-and-stick underlayment per Miami-Dade code for all replacement roofs, no exceptions.
- 3
Permitting. We pull permits and coordinate inspections. Miami Beach has its own building department, and we know the reviewers. PGT openings stay protected under Miami-Dade High Velocity Hurricane Zone code requirements.
- 4
Tear-off and deck inspection. Old roofing comes off. We inspect the decking. Any soft spots get replaced before new roofing goes down. No covering up someone else’s rot.
- 5
Underlayment, flashing, and roofing install. Then we address every transition into your PGT windows and doors with new step flashing, counterflashing, and drip edge, followed by the roofing material.
- 6
Water test and cleanup. We run a water test on the roof and on the PGT openings below, walk the property with you, and run a magnetic nail sweep so you don’t find roofing debris in your planting beds in a year.
If we find a PGT product that needs replacement during the roofing job, we handle that too. PGT, CGI, CWS, ES Windows, and ECO Window Systems are all in our wheelhouse. One crew, one warranty, one phone number.
What PGT Roof Replacement & Installation Costs in Miami Beach
Prices below reflect what we’ve quoted on Miami Beach homes over the last two years. Roof size, pitch, accessibility, and material choice move the number.
- Full shingle replacement on a 1,800 sq ft single-story, PGT openings: $14,500 to $19,000
- Full tile replacement on a 2,400 sq ft two-story with steep pitch: $28,000 to $38,000
- Metal standing seam replacement on a 2,000 sq ft modern home: $22,000 to $31,000
- Roof-over with new peel-and-stick underlayment and reflash around PGT products only: $6,500 to $11,000
- Skylight curb rebuild and reflash: $850 to $1,400 per curb
What moves the price: the number of PGT openings your roofing crew has to flash around, roof pitch (anything over 6/12 costs more in labor and safety gear), and whether your decking needs replacing. We don’t change the price once work starts unless you approve a change in writing. Call (863) 656-0462 for a free estimate, and we’ll give you a number you can actually plan around.

FAQs
No, not typically. PGT’s warranty covers the window or door itself, not the roofing around it. But if the roofing contractor damages a PGT frame or breaks a seal during reflashing, PGT may deny a future claim. We take photos before and after around every PGT opening and use flashing methods that protect the unit.
Yes, we’re an independent PGT service provider and we can supply and install PGT, CGI, CWS, ES Windows, and ECO Window Systems products. If your roofing job uncovers a failed PGT unit, we handle it under the same contract and the same workmanship warranty. Call (863) 656-0462 to talk through what you’ve got.
Once permits clear, typically 2 to 4 weeks depending on material lead time and city review schedules. Shingle jobs move faster. Tile jobs depend on the tile manufacturer. We’ll give you a real timeline after the site walk.
Yes, we pull permits for every roof replacement. Miami Beach requires them, and inspections protect you as the homeowner. We coordinate with the city, and our work is done to meet or exceed Miami-Dade High Velocity Hurricane Zone code.
A properly installed shingle roof over new peel-and-stick underlayment should hold 20 to 25 years in this climate. Tile and metal go 30 to 50 years. The most important day in a roof’s life is installation day. That’s why we don’t rush it and why we water-test before we leave.
