AfterCGI Roof Replacement & Installation in Brownsville: What to Know First
CGI roof replacement and installation in Brownsville typically runs $9,800 to $24,000 depending on roof size, pitch, decking condition, and whether we’re tearing off one layer or two. Most jobs take 2 to 4 working days from tear-off to final inspection, with permit time adding roughly a week on the front end. We give you a written line-item quote before any work starts, so you know exactly what you’re paying for and why. If you own a home in Brownsville with a CGI-impact-rated build and your roof is at the end of its life, you’ll want a crew that understands how your exterior systems tie together, not just a crew that shows up with shingles and a nail gun. Call (727) 860-0593 and you’ll get a live person, any hour, any day.
How CGI Products Fail - and How We Fix Them
CGI is not a roofing brand. It’s a door and window manufacturer. But we take a lot of CGI calls from Brownsville homeowners whose roof has failed around the very products that were supposed to protect the house. When we replace a roof on a CGI home, the work has to account for what’s underneath the flashing and what’s hanging on the walls. Here’s what we see, specifically:
- Flashing rot at CGI window head and sill intersections. Older CGI casement and single-hung units were installed with standard metal flashing that, after fifteen-plus years of Miami sun and Brownsville rain, separates at the corners. Water rides the flashing edge, runs behind the stucco, and rots the decking at the roofline before you ever see a stain on the ceiling. When we replace the roof, we pull back the first two feet of underlayment at every CGI opening and inspect the flashing. If it’s compromised, we re-flash correctly before the new roof goes down. A roofer who skips this will sell you a roof that leaks in two years, and you will blame the new roof. It was never the shingles.
- Condensation-driven deck rot around CGI fixed-lite picture windows. Brownsvillle homes built before 2005 often put large fixed CGI windows on the east and west elevations. These units sweat in our humidity. The moisture sits on the interior sill, wicks into the drywall, and next thing you know the roof decking at the soffit line is soft. It is a roof replacement in the sense that the wood is being replaced. It’s also a conversation about ventilation and window condensation that most roofing companies never want to have. We have it because it’s the actual cause.
- Hurricane strap retrofits that were never strapped. Some resales in Brownsville are sold with a CGI window sticker and a roof that was never tied down to new Miami-Dade code. We see clips rusted, missing, or never installed. On a roof replacement, that’s a life safety issue and a code requirement. We add or replace the clips and the inspector sees them before the underlayment goes on. If you’re paying for a roof, you shouldn’t have to ask for this. We just do it.
- Improper roof-to-wall tie at CGI sliding-glass door heads. The big CGI sliding doors collect a lot of wind load, and the roof deck at the header takes the abuse. Tear-offs on older Brownsville homes often reveal decking that’s been moving at the header for years, nails popped, underlayment shredded. We replace that decking and install roof-to-wall strapping per the current wind code. It’s not optional work, but it’s the work that keeps your CGI slider from becoming the weak point in a named storm.
- Secondary water barrier failures above CGI multi-panel assemblies. Long runs of CGI stacked windows and multi-slide doors require a roof-to-wall transition that sheds water cleanly. We have seen new roofs fail because the contractor ran the underlayment behind the CGI frame and sealed it with something that does not flex. Biscayne Bay air moves on this low-rise line, and rigid sealants crack. We use membrane materials that stay elastic, and we do the transition in a way that water can only go down and out.
Our CGI Roof Replacement & Installation Process
- 1
Phone call and site visit. You call (727) 860-0593. A live person answers. We come out to your Brownsville home at no trip charge inside the county, get on the roof, and inspect in person. Ed Winslow is usually the one walking it.
- 2
Written line-item quote. You get a number with the tear-off, decking, underlayment, drip edge, flashing, straps, fasteners, and labor separated out. No “roof package” line with a big number and a shrug. If you have a written estimate from someone else, we will give you a free second opinion on it.
- 3
Tear-off and deck inspection. We pull the old roof and expose the sheathing. This is where the real price gets confirmed. If your decking is rotted around CGI openings, we point it out, show you photos, and replace it with approved CDX plywood. The number changes only if the decking is bad, and you decide before we proceed.
- 4
Re-flashing and strapping at every CGI opening. Windows, sliders, headers, corners, and roof-to-wall junctions get new flashing and code-correct roof-to-wall strapping. This is the part most roofers hurry through because it’s not visible when the job is done. We slow down here.
- 5
Dry-in and finish roof. Underlayment goes down, then your shingle, tile, or metal system. We re-set any CGI window trim disturbed during the work and seal all transitions properly.
- 6
Final inspection and walkthrough. We walk the roof with you, show you the completed work, and you sign off. If any inspector flags something after we leave, we come back and fix it. The Done Right Promise is not a warranty card. It’s our operating policy.

Why Brownsville Homeowners Call Winslow Windows & Doors for CGI Work
We’ve been doing this in South Florida since 2011, and Ed Winslow grew up right here in Brownsville, learning to patch houses near Roberto Clemente Park with his grandfather. He knows the block. He knows how these houses were built and where they fail. When a CGI home needs a new roof, the conversation is not just about shingles. It’s about the envelope, about water intrusion, about storm ties, and about not paying for the same work twice. As an independent CGI service provider, we are not affiliated with the manufacturer, but we are authorized installers for eight other premium brands including PGT, CWS, ES Windows, and ECO Window Systems. That cross-brand experience means we see the details that a single-line roofer misses. Every technician who steps onto your property is background-checked and uniformed. A live person answers our phone 24/7. And if something is not done right, we make it right. That’s not a marketing line. Ed’s name is on the truck. My name’s on the truck. That means something.
FAQs
No, replacing your roof does not automatically void your CGI product warranty, but improper flashing or careless removal around window and door openings can cause the kind of damage CGI’s warranty would reasonably exclude. That’s why we are careful around every CGI penetration. As an independent CGI provider, we work in a way that protects both your roof and the products you already paid for.
We can usually get you on the schedule within 5 to 7 business days, and the tear-off and installation typically finishes in 2 to 4 working days. Permit timing varies by Miami-Dade, but once the permit is in hand, the crew moves fast. Call (727) 860-0593 and we will tell you the soonest we can start.
Not necessarily. But if a roof replacement is already pulling off stucco and flashing at the openings, it can be a smart time to replace old CGI single-hungs or casements, especially if they show condensation or seal failure. We can do both, and bundling the work saves on mobilization and re-flashing. We’ll give you a straight answer about whether your existing units are worth saving.
Re-flashing and strapping around CGI openings typically adds $600 to $1,400 on a standard single-story home, depending on how many windows and sliders are involved. It’s a fraction of the full roof cost, but it is the single most common reason new roofs leak on older South Florida homes. We include it in the quote from the start, not as a surprise add-on once the roof is open.
Yes. Every roof replacement we do in Miami-Dade is permitted, and the roof-to-wall clips and strapping are inspected before we dry in. If the inspector flags anything, we fix it at no additional cost. That’s part of the Done Right Promise, and it’s how we have operated since 2011.
Bring it to us. We offer a free second opinion on any written estimate, and we will compare it line by line. We will tell you if the cheaper number is realistic or if it’s missing the flashing and strapping work we’ve described here. Most Brownsville homeowners would rather know before the work starts than find out after the first heavy rain.
Call (727) 860-0593 to schedule your free estimate. Whether your CGI home is in Brownsville or a neighboring block, we’ll walk the roof, give you a straight written quote, and treat your house like Ed treats his own.
