CGI Roof Repair in Brownsville: What to Know First
CGI roof repair in Brownsville typically runs between $350 and $2,800 depending on whether we’re sealing a failing skylight curb, replacing impact-rated fasteners, or rebuilding flashing around a CGI-integrated roof system. Most repairs are completed in one visit, and we always give you a written line-item price before any work begins. If you own a home in Brownsville with CGI products tied into your roof assembly, this page is for you. We’re Winslow Windows & Doors, an independent CGI service provider since 2011, and you can reach a live person at (727) 860-0593 any hour of the day.
How CGI Products Fail - and How We Fix Them
CGI builds some of the toughest impact-rated windows and doors in Florida, but the roof is where even the best products get tested. Here’s what we actually see in Brownsville:
- CGI Estate Series skylight curb separation. The Estate line’s curb-mounted skylights rely on a raised aluminum frame that, after years of Brownsville sun and summer downpours, pulls away from the roof deck at the lag points. Water gets under the curb and travels along the trusses. We remove the unit, reset the curb with fresh flashing and butyl tape, and resecure with stainless fasteners rated for Miami-Dade wind loads.
- CGI Sentinel Series vent flashing cracks. The Sentinel ridge vents use a low-profile aluminum collar that expands and contracts at a different rate than the asphalt shingle around it. After eight to ten years, the collar develops hairline cracks at the corners. Homeowners notice stains on ceiling drywall first. We replace the collar with an upgraded alloy and reflash so the shingle laps correctly over the new metal.
- CGI Targa Series roof-to-wall transition leaks. Targa by CGI is common on Brownsville ranch homes where a flat roof meets a vertical wall. The original transition flashing was often installed with exposed fasteners. Any exposed fastener is a future leak. We strip the old flashing, install a seamless new transition, and cover every fastener with a sealed counterflashing so water never touches bare metal.
- Impact-rated roof hatch gasket failure. CGI roof hatches on older Brownsville homes have a rubber bulb gasket around the perimeter that goes brittle in about seven years of Florida heat. Once it hardens, the hatch won’t seal, and wind-driven rain finds its way in. We replace the gasket with an OEM-spec material and test the seal with a water wand before we pack up.
- OEM fastener corrosion at bracket points. On CGI’s attached roof-mounted products, the original zinc-coated fasteners eventually rust at the bracket where the product meets the roof. This is especially true within three miles of the coast, where salt air accelerates corrosion. We swap them for 316 stainless and touch up any bracket scoring with an anti-corrosion coating so the repair doesn’t become the next problem.
What sets CGI repairs apart from other brands is the tight integration between the product and the roof system. CGI engineers their frames for a specific installation envelope. When a roofer treats a CGI curb, vent, or hatch like it’s just another penetration, that’s when leaks start. Our techs were trained on these products, and we understand the tolerance the manufacturer built into them.
Our CGI Roof Repair Process
Every CGI roof repair in Brownsville follows the same disciplined sequence. No shortcuts, no guesswork, no change orders at the end.
- 1
Call and diagnosis. You call (727) 860-0593, a live person answers, and we schedule a time that works for you. If you’re inside our home county, there’s no trip charge.
- 2
On-site inspection. A background-checked, uniformed tech arrives and inspects the full CGI product-to-roof connection: curbs, flashings, fasteners, gaskets, and sealant beads. We take photos and show you exactly what we found.
- 3
Written line-item estimate. Before any work starts, you get a fixed price in writing. If a neighbor or another contractor gave you an estimate, bring it - we’ll give you a free second opinion.
- 4
The repair. We make the call on OEM versus aftermarket parts with you, not for you. If the OEM part is available and warranty-sensitive, we use it. If a quality aftermarket part will outlast the original (like 316 stainless fasteners), we tell you why.
- 5
Water test and cleanup. We water-test every repaired penetration before we leave. Then we sweep, magnet-sweep for loose fasteners, and walk you through what we did.
- 6
The Done Right Promise. If it’s not done right, we come back and make it right. Ed Winslow’s name is on the truck, and on every repair we do.
What CGI Roof Repair Costs in Brownsville

If you want a precise number, call us at (727) 860-0593. Estimates are free, and the price we quote is the price you pay.
Why Brownsville Homeowners Call Winslow Windows & Doors for CGI Work
Ed Winslow grew up in the Brownsville neighborhood of Miami, spending summers helping his grandfather patch up homes near the old Roberto Clemente Park. That’s probably where the itch to work with his hands started. He trained in building construction technology at Miami Dade College, then spent years in the field before putting his own name on a truck. Today, when a Brownsville homeowner calls about a CGI roof leak, they get Ed’s people, not a call center.
We’ve been doing this since 2011. Every tech is background-checked and arrives in uniform. We answer the phone 24/7. And because we install PGT, CWS, ES Windows, and ECO Window Systems alongside CGI, we understand how these roofs and walls work together, not just one product in isolation. When you call Winslow for CGI roof repair, you get the company with a published address, a license number, and Ed Winslow’s word backing every repair. A neighbor you can call at 2 a.m., and someone will actually answer.
FAQs
No, not when it’s done correctly. CGI’s warranty covers the product itself, not the roofing seal around it. As an independent CGI service provider, we follow the manufacturer’s installation envelope so your existing CGI warranty stays intact. We’ll tell you before any work starts if a repair might affect coverage.
Yes, in most cases we can source OEM CGI parts directly. For some older CGI lines, like the original Targa and Estate series, the OEM part may be discontinued. That’s where our experience helps: we know which aftermarket components match the original tolerance and which ones don’t. We’ll show you both options before we cut anything.
Call (727) 860-0593 and you’ll get a live answer, day or night. We’ll schedule your inspection at the first available time that works for you, and if you’re inside our home county, there’s no trip charge. Most repairs are done in a single visit.
If it’s the same penetration leaking twice, repair is usually a band-aid over a bad original install. We’ll tell you honestly which path makes sense. If replacement is the right call, we’ll give you a written quote and walk through what a new CGI-integrated roof connection should look like. Call (727) 860-0593 and we’ll inspect it properly.
Yes. We take $40 off any repair over $200, we give seniors and veterans a permanent 10% discount, and we’ll give you a free second opinion on any written estimate you already have. These aren’t promotions. They’re standing offers that have been our policy since 2011.
