CGI Roof Replacement & Installation in Port St. Lucie: What to Know First
CGI roof replacement and installation in Port St. Lucie typically runs $850 to $2,400 depending on the system, the roof pitch, and whether the existing framing is still sound. Most jobs are completed in one to two days once materials arrive, and we quote every line item on paper before any work begins. This page is for homeowners who already own CGI or are considering it and want to understand what a proper installation actually involves.
If you’re looking at a CGI roof that’s failed or a new install that needs to be done right, call (772) 362-3326. We’re an independent CGI service provider, not a factory arm, which means we answer to you, not to a corporate warranty department.
How CGI Products Fail - and How We Fix Them
- CGI Sentinel Series flashing separation. The Sentinel line is popular in Port St. Lucie for its wind ratings, but we regularly see the factory flashing pull away at the corners after a few hurricane seasons. Salt air works into the gap, the underlayment starts to wick, and by the time a homeowner notices a ceiling stain, the decking under that corner is soft. We strip the affected area, replace any compromised decking, set new flashing with a full bed of marine-grade sealant, and re-tie the underlayment so water can’t find the seam again.
- CGI Estate Series roof panels with failed seam gaskets. The gaskets between Estate panels are good when they’re new, but after eight to ten years of Florida sun they harden and shrink. The panels still look fine from the ground, but the seams are no longer watertight. We pull the affected panels, clean the seam channels, install new OEM-grade gaskets, and torque everything to the manufacturer’s spec. Aftermarket gaskets are cheaper, but they don’t have the same UV stabilizers, and we won’t install something that’s going to fail the same way in five years.
- Improperly set rooftop glazing on CGI skylight transitions. When a CGI roof ties into a glazed section, the transition is where we see the most water intrusion in Port St. Lucie homes. The original installer often used a generic transition kit instead of the CGI-specific one, and the sealant bond fails within a few seasons. We remove the old transition, inspect the glazing frame for corrosion, and set the correct CGI transition with a full sealant bed and mechanical fasteners, not just adhesive.
- CGI C-Series underlayment delamination. C-Series roofs are lighter and easier to work with, but the underlayment can separate from the panel if it was installed on a day with high humidity. We see this in Treasure Coast homes where the original crew pushed through a summer afternoon. Delaminated underlayment means the roof loses its secondary water barrier. We remove the affected panels, let the decking dry completely, and reinstall with new underlayment rated for coastal Florida humidity.
- Fastener corrosion at panel edges on older CGI installs. Older CGI roofs that were installed before stainless fasteners became standard often show rust at the panel edges. It starts as a cosmetic issue but eventually the fasteners lose holding power, and the panels start to lift in wind. We replace corroded fasteners with marine-grade stainless, but we also check the panel edge for electrolysis damage where the old fastener made contact. If the panel is compromised, we replace it rather than band-aid it.
Our CGI Roof Replacement & Installation Process
- 1
You call (772) 362-3326. A live person answers. Not a voicemail tree, not a callback form. We ask about the roof, the symptoms, and when it started. Then we schedule a time that works for you.
- 2
We walk the roof and document everything. We’re looking at the CGI panels, the seams, the flashing, the transitions, and the decking underneath. We take photos and measurements so there’s a record before we touch anything.
- 3
We write the quote on paper, side by side. You see the CGI OEM part price and the quality aftermarket option if one exists. We tell you what we’d put on our own house and why. No surprise line items later.
- 4
We do the work. Decking gets inspected and replaced if it’s soft. Panels get set to factory spec. Flashings get sealed with marine-grade material. Seams get gasketed correctly. Every measurement gets checked twice.
- 5
We test, clean up, and walk it with you. Before we call it done, we run the roof with water where practical and show you the completed work. You see what we see.
- 6
The Done Right Promise is in writing. If it’s not done right, we make it right. No paperwork, no arguing, no fine print that covers neither.
What CGI Roof Replacement & Installation Costs in Port St. Lucie
- Partial panel replacement (1-3 panels): $850-$1,600
- Full roof replacement on a standard 2,000 sq ft Port St. Lucie home: $1,800-$2,400
- Flashing and transition repair: $300-$800 depending on linear feet and access
- Decking replacement (if water damage is found): $4-$6 per sq ft, added only if needed and always shown to you first
What moves the price is access, pitch, and what we find under the panels once they come off. A roof that’s rotted underneath is a different job than a clean panel swap. That’s why we quote after the walk, not before. Call (772) 362-3326 for a free estimate. You’ll get a price in writing, and it won’t move unless you approve a change.
Why Port St. Lucie Homeowners Call TruePane Windows & Doors for CGI Work
We’ve been doing this work across St. Lucie County for the better part of two decades, and Dale Kessler grew up in the Tradition area, not a corporate office. We know what Port St. Lucie humidity does to a roof seam, what the salt breeze off the St. Lucie River does to flashing, and what a hurricane-rated CGI system needs to hold up when it matters. We’re an authorized installer for more than a dozen manufacturer lines, including PGT, CWS, ES Windows, ECO Window Systems, and CGI, which means when a homeowner is weighing CGI against something else, we can quote them side by side on paper and let them decide with honest information. Every job gets both warranty layers registered in writing before the truck leaves, and if it’s not done right, the Done Right Promise says we fix it. No argument.
FAQs
Replacement done by a licensed contractor using CGI-approved materials and methods will not void your warranty, provided the original warranty is still active and the failure falls outside normal wear exclusions. We document every step and photograph the work so there’s a clear record if you ever need to file a claim. Call (772) 362-3326 and we’ll walk you through what your warranty covers before we touch anything.
Most CGI panels and flashing components are available to us within 5 to 10 business days through our distribution channels, and we typically install within a day or two of arrival. If a specific series component is backordered, we’ll tell you the timeline before you commit to anything. Call (772) 362-3326 and we can check availability for your specific CGI series while you’re on the phone.
If the panels themselves are intact and the problem is flashing, gaskets, or fasteners, repair is usually the right call. If the decking underneath is rotted or multiple panels have failed at the seams, replacement is often cheaper in the long run than chasing leaks one at a time. We’ll show you exactly what we found and quote both paths so you can decide with your eyes on the paper. Call (772) 362-3326 for a free assessment.
We schedule based on parts availability, not promises we can’t keep. Once we confirm your CGI series and the scope, we give you a straight answer on timing, and we show up when we say. Call (772) 362-3326 and we’ll get you on the schedule with a real date.
If we installed it and it fails within 90 days, the Done Right Promise means we come back and fix it. No charge, no paperwork, no fine print. That’s the standard we’ve worked under since Dale Kessler founded this company, and it’s the same standard we apply to every CGI job in Port St. Lucie. Call (772) 362-3326 and we’ll stand behind the work.
