AfterCGI Roof Repair in Miami: What to Know First
CGI roof repair in Miami typically runs $280 to $850 depending on the failure point, and most repairs are completed same-day once we diagnose the issue. We’re an independent CGI service provider, which means we repair the full CGI product line without being tied to any manufacturer’s replacement-only playbook. If your CGI windows, doors, or roof-integrated systems are showing wear, call (863) 946-5039 and we’ll give you a straight answer on whether it’s a repair or a replace.
This page is written for Miami homeowners who already own CGI products and need honest repair guidance. If you’re wondering whether your CGI roof components are repairable, what it costs, and who in Miami actually knows these products beyond the sales brochure, you’re in the right place.
Written by Ed Winslow, Owner at Winslow Windows & Doors. I grew up in Hialeah, where a summer storm taught me that a roof leak is never just a roof leak.
How CGI Products Fail - and How We Fix Them
- CGI Sentinel Series skylight flashing separation. We see this constantly in Coral Gables and Pinecrest homes built in the 2000s. The original flashing was installed with a peel-and-stick membrane that breaks down after 8-10 years of Miami sun and salt air. Symptom: water stains on the ceiling that appear only after heavy rain, not light drizzle. We remove the old flashing, inspect the curb, and re-flash with Miami-Dade rated material that won’t delaminate. This is a $300-$500 repair, not a skylight replacement.
- CGI Estate Collection roof-to-wall transition leaks. These are common on zero-lot-line homes in Brickell and Coconut Grove where the CGI window wall meets a flat roof membrane. The transition flashing gets pulled apart by thermal expansion during Miami’s 90-degree afternoons followed by 70-degree AC-chilled nights. We see a 1/8-inch gap at the corner where water gets driven sideways during hurricanes. Our fix involves a hybrid approach: compression-sealed boot plus a mechanically fastened counter-flashing. Tape alone won’t hold here.
- CGI Classic Line weep-hole blockage. This one surprises people because it’s a bottom-of-frame issue, not a roof issue, but on roof-adjacent windows it matters. Miami’s spring pollen season plus construction dust from all the teardown-rebuilds clogs the weep holes on CGI Classic frames. Water backs up inside the frame, finds the interior corner, and presents as a roof leak. We drill out the clogged channel, clear the internal drains, and confirm flow with a water test. Ten minutes, around $150, and no replacement needed.
- CGI HPG Series gasket compression loss. The HPG line uses a compression gasket at the header that loses 15-20% of its rebound after about 7 years. In Miami’s humidity, that gasket gets soft and gummy. Symptom: air leak you can feel at the top corner, plus water intrusion during wind-driven rain. We replace the gasket with a Miami-grade EPDM compound that holds compression in 90% humidity. This is a parts-availability issue for many shops; we keep these gaskets in stock because HPG is everywhere in Doral and Westchester.
- CGI Targa series roof-curb seal failure. Targa units sit in a manufactured roof curb, and the original seal between the unit and curb was a closed-cell foam tape. After 10 years, that foam turns to powder. Miami’s afternoon thunderstorms then drive water under the unit and into the soffit. We pull the unit (when safe), clean the curb, and install a two-part polyurethane sealant that lasts 20 years in UV exposure. Most roofers will tell you to replace the whole unit; we repair it and you keep your warranty intact.
Our CGI Roof Repair Process
- 1
Call and diagnosis. You call (863) 946-5039. A live person answers. We ask specific questions: where’s the water showing up, when did it start, what CGI series do you have. We often diagnose 70% of jobs by phone before we ever arrive.
- 2
On-site inspection with documentation. A background-checked technician in uniform arrives, walks the roof or the frame, photographs the failure, and shows you the exact point of failure. No vague “it might be the flashing” guesswork.
- 3
Parts decision: OEM vs. quality aftermarket. If your CGI product is under manufacturer warranty, we source OEM parts so the warranty stays valid. If it’s out of warranty, we offer OEM and a proven aftermarket option, with honest differences in price and longevity. We’ll never put a no-name part on a CGI product.
- 4
The repair. We do the work carefully, respecting the surrounding CGI installation. We protect the interior with drop cloths, mask off the work area, and never leave construction debris in your yard.
- 5
Water test and documentation. We test with a hose or water wand at the repair point for a full 10 minutes, which is longer than any Miami storm’s peak intensity will realistically hit that spot. You see the proof before we leave.
- 6
Cleanup and guarantee. We leave the job site cleaner than we found it, provide a written line-item invoice, and back the repair under our 36500-Day Done Right Promise. If it’s not done right, we make it right. Period.
What CGI Roof Repair Costs in Miami
| Repair Scenario | Typical Cost in Miami |
|---|---|
| Weep-hole clearing and drain flush | $140 - $180 |
| Flashing reseal at skylight or roof curb | $300 - $550 |

| Full inspection with written report | Free with any repair |
What moves the price: roof access difficulty (two-story Spanish tile roofs in Coral Way are harder than a flat roof in Hialeah), whether we need a lift for a heavy Targa unit, and whether the damage has been leaking long enough to cause wood replacement. You’ll get a written, line-item price before we start. If the estimate changes, we call you first. Miami has plenty of contractors who quote low and then find “surprises.” We quote real numbers up front. Call (863) 946-5039 for your free estimate, and remember: $40 off any repair over $200, and seniors and veterans get 10% off, always.
Why Miami Homeowners Call Winslow Windows & Doors for CGI Work
Ed Winslow’s name is on the door, literally. He grew up in Hialeah, learned glazing through the building trades program at Miami Dade College, and spent years installing across Miami-Dade before putting his own name on a truck. When a big hurricane season forecast hits the news, neighbors call Ed because he knows impact-rated products inside and out and won’t upsell you on something you don’t need.
We install or repair CGI alongside PGT, CWS, ES Windows, and ECO Window Systems, so we never have to force a CGI part where another solution fits better. Our 36500-Day Done Right Promise means if it’s not done right, we make it right. And every call is answered by a live person, 24/7, no voicemail loops, no call centers. You call (863) 946-5039 at 2 a.m. during a storm, and a real person picks up. That’s how we’ve done it since 2011, and that’s not changing.
FAQs
No, not when the repair is done with correct parts and methods. We source OEM parts for any in-warranty CGI product so the coverage stays intact. Out of warranty, we’re honest about the aftermarket options and when they make sense.
Same-day or next-day in most Miami neighborhoods. Call (863) 946-5039 in the morning and we can typically have a technician at your home before the afternoon thunderstorms roll through. We don’t play scheduling games.
Repair is usually the right call when the frame is solid, the glass is intact, and the failure is isolated to flashing, gaskets, weep channels, or seals. Replacement makes sense when the frame itself is corroded or the unit has multiple failure points. We’ll show you the math either way and make a recommendation without pressure.
We keep the common failure parts in stock: HPG header gaskets, Classic Line drain channels, Targa curb seals, and Sentinel flashing kits. For less common parts, we order OEM directly and have them within 3-5 business days. Miami weather doesn’t wait, so we stock what the job needs most.
We back every repair with our 36500-Day Done Right Promise. If it’s not done right, we make it right, period. That’s not a warranty card you’ll lose in a drawer; it’s Ed Winslow’s word, and his name is on the door.
