CGI Roof Replacement & Installation in Miami: What to Know First
CGI roof replacement and installation in Miami typically runs $11,000 to $28,000 for a full tear-off and new system, with most homes landing between $14,000 and $19,000 depending on roof complexity, material choice, and structural condition. We’re not the cheapest in town and we’re not trying to be. Most CGI jobs we take on are complete tear-offs with new underlayment, flashings, and fasteners because the roof was done wrong the first time. If you own a CGI-built or CGI-equipped home in Miami and the roof is failing, this page tells you what we see in the field, what it costs, and how we fix it. Call (844) 901-4551 and a live person answers. Every time. 24/7.
How CGI Products Fail — and How We Fix Them
CGI makes a hell of an impact window and door. But the roof over those windows is where we get called when things go sideways. Here’s what we find on CGI homes across Miami:
- Factory-seam separation on CGI’s older standing-seam panels. Homes built with CGI roofing in the mid-2000s (especially in Kendale Lakes and Westchester) start showing seam separation around year 12 to 15. The factory-applied sealant between panel legs dries out faster in Miami’s salt air than CGI’s own literature suggests. We pull the panels, clean the legs with the proper solvent, re-seal with a marine-grade butyl tape, and re-clip the seam. A quick caulk job on top won’t hold. We’ve been back to jobs where someone tried that. It fails again within a season.
- Fastener back-out at the eave edge on CGI’s corrugated profile. The thermal expansion and contraction in Miami’s heat-rain-heat cycle works fasteners loose at the eave line first. You’ll see lifted panels or little bumps pushing up from underneath. The fix is replacing the fasteners, not tightening them into stripped holes. We use an oversized replacement screw with the correct neoprene washer so the panel seats properly without tearing the metal.
- Leak-through at penetrations where the original installer used the wrong boot. Pipe boots, vent boots, and exhaust hoods on CGI roofs need boots sized for the actual profile depth of the panel, not whatever was on the truck that day. We see this constantly in Hialeah and Miami Springs where the original roofing crew used flat-profile boots on a corrugated panel, leaving a small gap at the base that leaks slowly for years before anyone notices. There’s no patching a wrong boot. We pull it, install the right profile boot with a proper storm collar, and that penetration will outlast the panel around it.
- Improperly terminated ridge caps on CGI tile-look panels. CGI’s stone-coated or tile-profile systems fail at the ridge line when the original installer cuts corners: insufficient overlap, no weep holes, or foil-faced tape used where a metal closure strip belongs. Water gets in, runs down the rafters, and the homeowner calls us about a mystery leak that only shows up in wind-driven rain. We remove the cap, install the correct CGI-profile closure, and re-bed everything in a sealant that’s rated for Miami’s UV load. The difference between a ridge done right and a ridge done fast is about thirty minutes of labor. That’s what separates a roof that lasts from one that doesn’t.
- Underlayment rot beneath mechanically fastened CGI panels. Here’s the one nobody wants to hear. A mechanically fastened metal roof is only as waterproof as the underlayment below it. If the original underlayment was cheap felt or a single layer of synthetic that’s now breaking down, the screws become leak points, not the panels. We see this most in Coral Gables and Pinecrest on two-story CGI homes where the roof was flashed against a wall or chimney. The panels come up, the rotted deck gets replaced, a high-temperature peel-and-stick underlayment goes down, and the panels go back on. If you’re seeing stains on your ceiling that you cannot trace to a specific spot, this is often the cause.
Our CGI Roof Replacement & Installation Process
Every CGI roof job follows the same six steps. Nothing gets skipped, and you’ll know where things stand the whole way through.
- 1
The call. You reach a live person at (844) 901-4551. We schedule a visit. No trip charge inside Miami-Dade County. If you’ve already got a written estimate from another company, bring it out: we’ll give you a free second opinion on it.
- 2
The roof-level inspection. We walk the roof, get into the attic where possible, and document what we find with photos you keep. We’re looking at panel condition, fastener spacing, underlayment health, flashing details, and what’s happening at the penetrations. On CGI roofs, the failure is rarely one dramatic thing. It’s usually three or four small things stacking up over the years.
- 3
The honest conversation. Sometimes the right call is a repair, not a replacement. If a roof has ten years left in it and only needs boots replaced, we’ll tell you that and write the quote accordingly. If the underlayment is shot or the panels are too far gone, we’ll tell you that too. Nobody wants to sell you a roof you don’t need. My name’s on the permit. That means I’m not going anywhere until it’s right.
- 4
Material selection. If we’re replacing, we talk through what goes back on: panel profile, gauge, finish, and whether you want a standing seam, corrugated, or tile-look system. As an independent CGI service provider, we’re not locked into pushing one manufacturer. We install whatever is the right fit for your home, and sometimes that’s the same CGI profile you already have, and sometimes it’s a better-suited profile from our approved lineup of materials.
- 5
The install. Tear-off, deck repair or replacement as needed, new underlayment, new panel installation with correct fasteners and clips, all flashings re-done, all penetrations re-booted. Our crews are background-checked and uniformed. If there’s an HOA approval, we’ll make sure it’s in hand before we start.
- 6
The test and the walkthrough. We water-test critical details, inspect every seam and penetration, and walk you through what we did and why. Then comes the Winslow Done Right Promise: if it’s not done right, we make it right. That promise does not expire. It never has.
What CGI Roof Replacement & Installation Costs in Miami
Roof pricing in Miami is not a mystery, and any contractor who treats it like one is doing you a disservice. Here’s what we quote for common CGI roof scenarios:
- Full tear-off and replacement, standing seam, single-story Miami ranch: $13,000 to $22,000 depending on square footage, deck condition, and fascia work.
- Full tear-off and replacement, corrugated or tile-look profile, two-story home: $16,000 to $28,000. Two-story roofs have more edge conditions, more flashing intersections, and more labor.
- Eave-edge fastener replacement and re-securing (no tear-off): $1,200 to $3,500 depending on linear footage and panel condition.
- Penetration boot replacement, per penetration: $175 to $400 installed, including the correct boot and storm collar.
- Underlayment replacement with panel re-install (partial roof): $7,000 to $15,000 depending on how much decking has to be replaced.
What moves the price: roof pitch (steeper costs more), number of stories, how much decking needs replacement, whether the HOA is involved, and material gauge. We give fixed pricing with no change orders on approved scope. If we find rotted decking after tear-off, you’ll see it before we touch it, and the price for any additional work is agreed on in writing before we proceed.

Why Miami Homeowners Call Winslow Windows & Doors for CGI Work
Because when the roof leaks, you don’t want a ticket number. You want a person. Winslow Windows & Doors has been serving Miami since 2011, and Ed Winslow’s name is on the truck, on the license, and on the permit for every job. We’re the locally owned alternative to the faceless national chains, and that’s not a slogan, it’s a fact you can verify at our published address. Every call is answered by a live person, 24/7. Not a voicemail. Not a call center reading a script. A real person who can talk to you about your roof. We also install PGT, CWS, ES Windows, and ECO Window Systems, so if the roofing issue turns into a window or door conversation, we can handle that too. One company, one phone number, one owner who answers when you call.
FAQs
No, not if the work is done correctly. The CGI warranty that applies to your windows and doors is separate from whatever roofing system is installed over them. Roof work does not affect your CGI window or door warranty. That said, sloppy roofing work can damage window trim or sealant, which is exactly why we take care to protect every opening during a tear-off and re-installation.
For emergency repairs like an active leak or storm damage, we’ll get someone out fast. For full replacements, we schedule based on the size of the job and current workload. Miami’s weather does not care about schedules, and neither do we. Call (844) 901-4551 and we’ll give you a straight answer about timing.
That depends on what we find during the inspection. A roof with isolated penetration problems and healthy underlayment is a repair. A roof with failing underlayment, multiple leaking seams, and panels past their service life is a replacement. We’ll show you photos and explain what we’re seeing. The decision is yours, but you’ll have honest information to make it.
That depends on your policy and the cause of the damage. Storm damage is often covered. Age-related wear is generally not. We do not handle insurance claims direct, but we provide thorough documentation with photos that many Miami homeowners use successfully when filing. We’ll give you the paperwork you need and an itemized invoice your adjuster can read without calling back for clarification.
When the home already has a CGI standing-seam or corrugated profile and the panels are in reinstallable condition, we use them. When panels must be replaced, we match the profile and finish as closely as possible from our approved material sources. As an independent CGI service provider, we’re not bound to one product line, but we are bound to doing the job right. You’ll know exactly what’s going on your roof before it’s ordered. Call (844) 901-4551 and we’ll walk you through it.
