We’re an independent CGI service provider in Miami, and we repair CGI roofing products that have failed due to age, impact, or installation error. Most CGI roof repairs on Miami homes take one to two days once parts are on hand, and we give you an upfront line-item price before any work starts. No vague ranges, no surprise change orders, and no trip charge inside Miami-Dade County.

This page is for Miami homeowners who already know they have a CGI product overhead and need straight answers: what actually fails on these roofs, what it costs to fix, and who in Miami knows the brand well enough to do the job right the first time. Ed Winslow has been working South Florida exteriors since 2011, and our technicians have repaired enough CGI systems across neighborhoods like Kendall, Pinecrest, Coral Gables, and Cutler Bay to know exactly what to look for when something goes wrong.

How CGI Products Fail — and How We Fix Them

• Flashing separation at the eave line on CGI standing-seam panels. Miami’s summer heat cycles expand and contract metal roofing more aggressively than most climates in the continental U.S. On CGI’s standing-seam profile, we regularly see the eave flashing pull away from the panel edge after enough years of that movement. The panel itself is usually fine; the fix is removing the old sealant, resetting the flashing with new butyl tape, and refastening to manufacturer spacing. That’s a one-day repair we handle routinely.
• Fastener back-out on older CGI corrugated profiles. Homes along the coast in neighborhoods like Key Biscayne and North Beach get constant salt-laden wind. On CGI’s corrugated lines installed 10-plus years ago, the original neoprene washers harden and shrink, allowing the fastener head to sit proud of the panel. Water then works its way under the washer and down the fastener shank. The fix is replacing fasteners with proper EPDM-washered screws, not just tightening the old ones. Tightening a compromised washer does nothing but strip the hole.
• Ponding water at low slopes on reskinned CGI flat-to-pitch conversions. Some Miami homes originally built with low-slope built-up roofs were later reskinned with metal. If the slope wasn’t brought up to CGI’s minimum pitch spec before the panels went on, water pools behind the laps. We’ve seen this most often on mid-century concrete-block homes in Westchester and West Miami that were converted decades ago. The real fix is correcting slope at the deck; the shortcut is adding a rain diverter, which never holds. We’ll give you the honest answer even when it’s the more expensive one.
• Panel lap seal failure on CGI corrugated after repeated pressure washing. Miami homeowners pressure wash everything. On corrugated panels with a head lap, a zero-degree nozzle held too close will blast out the factory lap sealant and let wind-driven rain climb the lap. You can’t see this failure from the ground. We find it during inspections where the homeowner says the roof only leaks during certain storm wind directions. The repair is clean, re-seal, and re-set the lap — and after we’re done, we’ll tell you how to wash it without doing this again.
• Condensation drip marks on the underside of CGI panels in unconditioned attic spaces. This is a Miami-specific reality: high overnight humidity and daytime heat with no attic ventilation causes underside condensation on metal panels. The homeowner sees drip marks on insulation and assumes the roof leaks. It doesn’t. The fix is ventilation correction at the ridge or gable, which we can handle. We’d rather spend ten minutes diagnosing this correctly than sell you a repair you don’t need.

Our CGI Roof Repair Process

1. 1
   You call (844) 901-4551. A live person answers. We take the address, the symptom, and schedule the visit. No ticket number, no callback queue. Since 2011, this is how Winslow runs every call.
2. 2
   We inspect the CGI product in place. Our tech walks the roof or attic space, identifies the failure point, and documents it. We’re checking not just the visible issue but what caused it, because fixing the symptom without the cause just means you call us again next hurricane season.
3. 3
   We determine the right parts. For warranty-sensitive repairs, we use CGI OEM components where they’re available and the product is still in production. For discontinued lines, we use quality aftermarket parts that match the panel profile and gauge, with a clear explanation of the trade-off and your sign-off before we order anything.
4. 4
   We give you a line-item written estimate. Fixed price. No “we’ll see what we find” language. You’ll know what every dollar covers before you approve the work.
5. 5
   We do the repair and test it. One visit for diagnosis, one visit for the repair, and a water test where the failure mode allows it. Every CGI repair we make is backed by the Done Right Promise: if it’s not done right, we make it right, period.
6. 6
   We clean up and walk you through what we did. You’ll see the photos taken before, during, and after. Ed’s name is on the door, and on the permit, and on every job we do in Miami.

What CGI Roof Repair Costs in Miami

CGI roof repair in Miami runs on a wide range because the products differ so much by profile, age, and failure type. Here’s what you can expect based on the jobs we actually see:

• Flashing reseal at a single eave or penetration: $350–$700 depending on linear feet and access
• Fastener replacement on a corrugated section (50-square-foot area): $450–$900
• Panel lap seal repair on a corrugated roof, single side: $400–$850
• Replacing a single damaged corrugated panel: $800–$1,400 installed, depending on gauge and profile
• Standing-seam panel replacement, single panel with clip resetting: $1,100–$2,000

What moves the price in Miami? Roof pitch, whether we can work from the eave or need full staging, single-story versus second-story access, and whether the panel is still in production. Hard-to-match colors and discontinued profiles cost more because the match matters on a Miami roofline that gets sun year-round. Call (844) 901-4551 for a written estimate on your specific CGI roof. The estimate is free and the price won’t change once we start.
