AfterCGI Roof Replacement & Installation in Miami: What to Know First
CGI roof replacement and installation in Miami typically runs $8,500 to $22,000 depending on scope, and TruePane Windows & Doors handles the full job as an independent CGI service provider. We’re not affiliated with CGI, but we’ve installed and replaced their products across Miami for years, and we know which lines hold up to coastal wind loads and which ones don’t. Most full replacements take two to four working days once materials land. This page is for CGI owners who want straight answers on failure modes, parts, pricing, and what a proper install actually looks like. Call (561) 956-2754 for a free estimate.
Key Takeaways
- CGI replacement jobs in Miami run $8,500 to $22,000 depending on roof structure, glass package, and permit requirements.
- We’re an independent CGI service provider, not an authorized dealer, so our recommendations are based on what’s right for your roof, not a quota.
- Every job is backed by the 90-Day Done Right Promise and The Keystone Standard: both warranty layers registered in writing before we leave the driveway.
- A live person answers the phone 24/7 at (561) 956-2754, not a voicemail tree.
How CGI Products Fail - and How We Fix Them
CGI makes a solid product, but Miami’s climate finds the weak points. Here’s what we actually see on roofs across Coral Gables, Cutler Bay, Kendall, and the rest of the Miami metro.
- CGI Estate Collection glass units with failing perimeter seals. The Estate line shows up on a lot of Miami roofs as skylights or glazed roof sections. The sealant CGI uses at the frame-to-glass junction breaks down after eight to twelve years of direct South Florida UV. Water doesn’t pour in, it wicks, and by the time you see a stain on the ceiling, the framing underneath is already soft. We pull the old unit, inspect the curb, replace any rot, and set the new glass with a marine-grade sealant rated for full sun exposure.
- CGI Classic Series frame corrosion at the anchor points. On roof-mounted units, the Classic Series’ aluminum frame holds up well until salt spray and standing rainwater sit on the anchors. We see rusted fasteners and galvanic corrosion where the steel anchor meets the aluminum frame, especially on homes within a mile of Biscayne Bay. The fix is replacing the anchors with isolated stainless hardware and re-flashing the base so water sheets away instead of pooling.
- CGI Impact Series roof windows with blown laminated interlayers. The Impact Series uses a multi-layer glass makeup, and when the PVB interlayer starts to delaminate, you get a milky haze at the edges that creeps inward over two or three hurricane seasons. That’s not a cleaning issue, and CGI’s own warranty documentation doesn’t always make that clear. We’ve replaced enough of these to know the difference on sight.
- CGI Signature Series flashing failures on flat and low-slope roofs. Miami’s afternoon thunderstorms dump inches in an hour, and a low-slope roof with a Signature Series skylight is asking a lot of the flashing. When the flashing was never properly integrated into the roofing membrane, water backs up at the uphill edge and works its way under the frame. We re-flash with a two-stage system: a primary membrane bond plus a metal counter-flashing that overlaps the frame by a minimum of two inches.
- CGI operable roof hatches with closure mechanisms that bind after storm season. The hatch models CGI produced for roof access have a compression closure that misbehaves after the frame gets flexed by hurricane-force gusts. The handle feels tight, but the seal isn’t actually compressing. We realign the frame, replace the gasket, and re-torque the closure points so the hatch closes square and stays closed.
Our CGI Roof Replacement & Installation Process
- 1
We come out and measure. Not after we give a price. Before. We measure the opening twice, check the roof structure underneath, and look at how water currently flows around the unit.
- 2
We quote plainly. You get a written line-item quote with CGI options and, where it makes sense, comparable lines from PGT, CWS, ES Windows, or ECO Window Systems side by side on paper. No change orders hiding behind vague language.
- 3
We decide on parts. OEM when it’s warranted and available. Quality aftermarket glass and hardware when the OEM part is backordered or not the right fit for the roof’s age and exposure. We tell you exactly what we’re ordering and why.
- 4
We pull permits and schedule. Miami-Dade permits for roof penetrations are not optional. We pull them, and we pass inspections.
- 5
We install and seal. The old unit comes out, the curb or framing gets inspected and repaired, the new unit goes in, and the flashing is tied into the roof membrane correctly. Not caulked over. Integrated.
- 6
We test, register warranties, and clean up. We water-test the seal, register both warranty layers in writing, and leave the roof cleaner than we found it. The 90-Day Done Right Promise means if something isn’t right, we come back and make it right with no paperwork argument.

We don’t pad the quote to cover surprises we didn’t tell you about. Call (561) 956-2754 for an exact number on your specific roof.
Why Miami Homeowners Call TruePane Windows & Doors for CGI Work
Dale Kessler started this company in 2008 after years of seeing out-of-true installs and voided warranties treated like the homeowner’s problem. He runs TruePane with a simple rule he learned at his father’s glazing shop in Ohio: if it’s not worth putting in the contract, it’s not worth saying out loud.
That’s why every CGI job we touch gets The Keystone Standard: both manufacturer warranty layers registered in writing, durations stated, before the truck pulls away. The 90-Day Done Right Promise covers the workmanship. Our techs are background-checked, uniformed, and trained on CGI’s specific frame types and glass makeup. And when a Miami homeowner calls about their CGI roof unit, a live person answers the phone at (561) 956-2754, 24 hours a day, 7 days a week. We’ve been serving this community for over 42 years, and we plan to be here in thirty more.
Frequently Asked Questions
Yes, when the installation is done correctly and documented. The key is registering the new unit’s warranty in writing and keeping the installation record. That’s what The Keystone Standard is for. We register both warranty layers before leaving your roof. Call (561) 956-2754 and we’ll walk you through what your specific CGI unit’s warranty requires.
Most CGI roof components ship to Miami within five to ten business days if the warehouse has stock. Custom glass packages can take three to four weeks. We tell you the lead time before you commit so there’s no second appointment left hanging.
If the leak is at the flashing, repair is usually the right call. If the glass unit itself has a failed seal or the frame is corroded through, replacement costs less over time. We’ll show you the condition in photos before we recommend either direction. Call (561) 956-2754 for an honest assessment.
Yes. Miami-Dade County requires permits for roof penetrations, and we pull them on every job that needs one. We also pass the inspections. No homeowner should accept a roof install that skipped the permit office.
We work on the glazing itself, not just the roof around it. A roofer can flash the perimeter, but when the glass unit fails or the frame corrodes, you need someone who knows CGI’s frame details and glass makeup. We do both, and we stand behind the work in writing. Call (561) 956-2754 for a free estimate.
