CGI Roof Repair in South Miami: What to Know First

CGI roof repair in South Miami typically costs between $350 and $1,800 depending on whether you’re dealing with a failed seal, a cracked panel, or structural damage around the roof penetration, and most repairs on our end are completed within one to two days once parts are in hand. We’re an independent CGI service provider, which means we diagnose and repair your existing CGI products without being tied to the manufacturer’s timeline or pricing structure. This page is for homeowners who own CGI windows, doors, or roof-adjacent products and need someone who actually knows how they fail in South Miami’s climate. If you suspect damage, call (850) 930-1813 and Ed Winslow’s team will walk you through what we’re seeing.

How CGI Products Fail - and How We Fix Them

CGI makes a solid impact product line, but South Miami’s heat, humidity, and salt air create failure patterns that don’t show up in every market. Here’s what we actually see when we’re called out, and how we address it:

• CGI Sentinel Series - seal failure at roof-to-frame junctions. The Sentinel line uses a heavy aluminum frame with a proprietary sealant at the factory, but years of thermal expansion and contraction in South Miami’s 90-degree summer heat causes that seal to fatigue. The symptom is usually a faint mildew smell near the window or a soft spot in the drywall above the frame. Our fix involves removing the interior trim, re-flashing the rough opening, and applying a marine-grade sealant that handles our humidity better than standard construction caulk.
• CGI Estate Collection - lower track corrosion from roof runoff. Houses in areas like Riviera and the neighborhoods off Sunset Drive get heavy roof runoff during summer storms. When gutters drain directly onto an Estate Collection sill, the aluminum track eventually pits and corrodes. Homeowners mistake it for a cleaning issue, but wire-brushing it only makes it worse. We replace the track, reposition the downspout, and coat the new track with a corrosion inhibitor rated for South Florida’s salt-laden air.
• CGI Targa Series - laminate separation along the top rail. We’ve repaired enough Targa units in South Miami to know the top rail is the stress point. Years of sun on the dark bronze finish causes the laminate interlayer to pull away at the upper corners. It starts as a small white or foggy patch and grows. This is not a re-seal job; the glass unit needs replacement. We’ll spec a replacement IG unit that matches the existing glass package, and we’ll reuse the original frame if it’s still true.
• CGI Architectural Series - weathered weatherstripping along roof-adjacent transoms. Transom windows mounted high near rooflines catch the brunt of afternoon sun. The weatherstripping on Architectural Series units in those locations turns brittle and cracks within 8 to 10 years. Water intrusion during wind-driven rain then follows the frame to the nearest interior corner. We strip the old gasket, clean the channel, and install a closed-cell replacement that outlasts the original.
• CGI Classic Series - storm-damaged screens and mullions near rooflines. Hail and branch damage during hurricane season tend to hit upper-floor Classic Series units first. Bent mullions and torn screens are common, but the hidden problem is micro-fractures at the mullion-to-frame fasteners. We replace the mullion, inspect the frame for hairline cracks, and torque every fastener to the manufacturer’s original spec rather than just cranking them down.

Our CGI Roof Repair Process

When you’re dealing with the point where a roof meets a window or door, there’s no room for guesswork. Here’s how our repair process works, from first call to final walkthrough:

1. 1
   Live answer, honest intake. You call (850) 930-1813 and a real person picks up, no phone tree and no callback from a call center. We ask what you’re seeing, where the leak is in relation to the roof, and whether you’ve had any prior repair attempts. We give you a rough idea of what we suspect before we even show up.
2. 2
   On-site diagnostics. A background-checked, uniformed technician comes out, walks the roof line, inspects the affected CGI unit, and tests for water paths using non-invasive methods first. We do not open up a wall or pull trim until we can show you why we’re going in.
3. 3
   Parts decision: OEM vs. quality aftermarket. For glass units and frames, we always recommend OEM CGI parts to preserve warranty status and resale value. For consumables like sealants, weatherstripping, and fasteners, we use high-grade aftermarket products that outperform what came from the factory. We’ll explain the trade-off in plain English and give you a written line-item price before any work starts.
4. 4
   The repair, done right. We remove only what’s necessary, fix the root cause, and re-seal every penetration with products suited to South Miami’s climate. No shortcuts, no cover-up caulk jobs, and no surprises on the invoice.
5. 5
   Testing and verification. We water-test the repair where practical, inspect the interior for drainage, and confirm the unit is seated, sealed, and square. If the roof itself needs work, we coordinate that while we’re on-site so you’re not left with one trade blaming another.
6. 6
   Cleanup and the Done Right Promise. We leave the job site the way we found it, and we back the work with our Done Right Promise. If it’s not done right, we make it right. Period.

What CGI Roof Repair Costs in South Miami

CGI repair pricing in South Miami depends on three things: what specifically failed, how accessible the unit is, and whether the roof penetration is part of the problem. Here are the ranges we quote most often:

• Weatherstripping or seal replacement on a roof-adjacent CGI unit: $350-$800
• Track corrosion repair or mullion replacement: $500-$1,200
• Glass unit replacement for a Targa or Sentinel series window: $800-$1,800
• Full frame replacement with roof re-flashing: $1,500-$3,200

What moves the price: whether we’re matching an existing finish, whether the unit is on a second story, and whether the roof structure itself needs reinforcement. We give you a fixed written quote before work begins. Call (850) 930-1813 for your free estimate, and if you have a written estimate from someone else, bring it in for a free second opinion.

Upfront pricing, live answers around the clock, and a Done Right Promise come standard. When you call Winslow, you’re getting a neighbor who has been doing this in South Miami since 2011, not a dispatcher reading from a script.
