CGI Roof Replacement & Installation in Westchester: What to Know First
CGI roof replacement and installation in Westchester typically runs between $14,000 and $38,000 depending on roof size, decking condition, and which CGI system you choose, with most full replacements completed in 2 to 5 working days once materials land. We’re an independent CGI service provider - not factory-authorized, which means we work for you, not the manufacturer - and we give every Westchester homeowner a written, line-item estimate before any work begins.
If you own CGI windows or doors and need a roof that matches that same level of hurricane protection, this page is for you. Call (850) 721-1218 and a real person picks up - day or night.

How CGI Products Fail - and How We Fix Them
- CGI Sentinel Storm Panel fastening points. On Westchester homes with CGI Sentinel panels, we see the mounting channels pull away from fascia boards that have gone soft from twenty years of afternoon storms rolling off the Everglades. The fix isn’t just replacing the panel - it’s pulling the channel, inspecting the underlying wood, and anchoring into fresh structure before the new panel goes on. A lot of crews skip that step, and the panel fails at the first hard blow.
- CGI Estate Collection roof-to-wall transitions. The Estate Collection runs heavy, and on older Westchester ranch homes the original roof decking wasn’t always rated for that kind of load at the perimeter. We routinely find cracked decking and loosened fasteners where the roof meets the wall. We sister in new decking and use longer fasteners with proper spacing before the roofing material goes down, so the whole assembly works as one system rather than fighting itself.
- CGI Targa series seal wear patterns. Targa by CGI is one of the most common lines we see in Westchester, and the seals around the roof penetration points dry out faster than the panels themselves. The symptom is water staining on the ceiling after a hard rain - which most homeowners assume is a roof leak. It’s usually the seal channel at the penetration, not the roof membrane. We replace the seal with a marine-grade equivalent and re-flash properly.
- OEM versus aftermarket fastening hardware. CGI’s factory hardware is good, but on salt-exposed Westchester properties within a few miles of the coast, we see the original zinc-coated fasteners corrode in as little as eight years. We spec stainless or high-grade coated fasteners depending on your exact location and exposure. It’s a small cost difference that keeps the roof system intact far longer.
- Improper previous installations. This is the big one. More than half the CGI roof work we take over in Westchester was installed by crews that never pulled permits or cut corners on underlayment. The panels can be perfectly good, but if the underlayment was cheap or torn during install, the roof fails from underneath. We strip it, inspect everything, and rebuild from the deck up - snapped photos included so you can see what we found.
Our CGI Roof Replacement & Installation Process

Call and talk to a person. You reach someone live at (850) 721-1218. No voicemail loop, no call center. Ed Winslow or one of our crew picks up and schedules your estimate.

On-site inspection and diagnostics. We walk the roof with you, check the decking, flashing, fastening points, and the condition of any integrated CGI components. You get a written, line-item report of what we found - not a vague verbal summary.
- 3
Parts decision. We discuss OEM versus quality aftermarket components based on your roof’s condition, your budget, and your long-term plans. We never push the more expensive option unless it’s the right call, and we explain why.
- 4
The work. Our background-checked, uniformed crew handles the removal, decking repair, and installation. Permits are pulled, inspections are scheduled, and the site stays clean while we work.
- 5
Testing and walkthrough. We test every penetration point, inspect the fastening pattern, and walk the finished roof with you. If anything isn’t right, we make it right before we leave.
- 6
Paperwork and the promise. You get the warranty documents and our Done Right Promise in writing. If it’s not done right, we come back.
What CGI Roof Replacement & Installation Costs in Westchester
Here’s what our Westchester customers actually pay for CGI roof work, based on the jobs we’ve done in the area:
- Full roof replacement with CGI-rated underlayment and decking repair: $14,000-$22,000 for a typical 1,400-1,800 sq ft Westchester ranch or split-level
- Full replacement with heavier CGI system and full decking replacement: $24,000-$38,000 when existing decking is shot and structural repairs are needed
- Roof-to-wall transition repair and re-flashing (partial job): $1,800-$4,200 depending on how many linear feet are involved and what the decking shows
- Seal and penetration point replacement (no full roof): $600-$1,800 for most single-story Westchester homes
The biggest swing factors are decking condition, roof pitch, and whether you need full underlayment replacement. We give exact numbers in writing before anything starts - no change orders because we missed something on the estimate.
