CGI Roof Repair in Coral Gables: What to Know First
CGI roof repair in Coral Gables runs from about $350 for a straightforward flashing reseal to $2,400 or more when a curb-mounted unit needs its frame pulled, rebuilt, and reinstalled. Most jobs take half a day on site, and we carry the common CGI glass packs and gaskets in our trucks so we’re not putting you off a week while parts ship. Call (954) 507-3613 and a live person answers, day or night.
This page is for homeowners in Coral Gables, Coconut Grove, South Miami, and the surrounding neighborhoods who have CGI roof glazing on their home and have noticed a drip, a fogged lite, or paint blistering around the curb. It is not a generic repair page with the CGI name pasted on. It is what we have learned from seventeen years of pulling apart, diagnosing, and properly resetting CGI units across Miami-Dade, including a lot of work within eight blocks of the Biltmore.
How CGI Products Fail - and How We Fix Them
- Sentinel 6300 curb-mounted skylight: failed curb flashing at the corners. This is the single most common CGI roof failure we see in Coral Gables. The roofer who flashed the original curb ran the membrane tight and neat, but they did not allow for the daily expansion and contraction of an aluminum curb under full Miami sun. After eight or ten years, the corner laps pull loose and water tracks into the ceiling drywall. We remove the old flashing, install new peel-and-stick flashing with proper corner boots, and remount the unit on fresh setting blocks. It holds.
- Estate Collection roof glass: seal failure between the lites. CGI’s Estate Collection uses insulated glass units, and like every insulated glass unit in South Florida, the edge seal eventually gives out from humidity and heat cycling. The symptom is fog between the panes that comes and goes with the weather. The fix is a new IG unit, and it matters that the replacement matches the original tint and low-E stack. We measure, order from a Miami glass fabricator who cuts to CGI specs, and set the new unit with the same shore-A durometer setting blocks the factory used. No off-the-shelf substitutions.
- CGI frameless roof lite: weep hole blockage and water pooling. Many roof glazing systems have small weep channels at the base of the glass to drain condensation and any incidental water. In Coral Gables, oak pollen and construction dust clog those channels within a few years, and then water pools against the bottom seal until it finds a way through. We see this on both the contemporary line and older products. The repair is methodical: clean the channels, test with a garden hose at low pressure, and replace any gasket that shows compression set.
- Sloped roof glazing on mid-century Coral Gables homes: aged sealant on the sight lines. Homes built in the 1950s and 60s along Granada Boulevard and the surrounding streets often have original or early replacement roof glazing with structural silicone sealant joints. Once that silicone loses adhesion, wind-driven rain from afternoon thunderstorms gets in. We remove the old sealant with a soft abrasive wheel, prime the joint properly, and reapply a commercial-grade structural silicone rated for Miami-Dade wind loads. Using cheap tub caulk here is how you get a callback next season.
- Hurricane impact roof windows from the area’s post-Andrew rebuilds: latch and arm wear. If your CGI roof window has hinged or operable vents, the crank mechanisms and locking arms wear out long before the glass does. Coral Gables sees enough salt air and seasonal humidity that the zinc-plated hardware on older units corrodes and binds. We keep CGI-compatible arms and latch sets on hand, and we replace the entire mechanism rather than greasing a worn one and pretending that is a repair.
Our CGI Roof Repair Process
A CGI roof repair follows a set order when we show up. It is not exciting, but it is repeatable, and repeatable is what keeps a roof dry.
- 1
Call and describe the symptom. A live person answers at (954) 507-3613 and asks specific questions: where is the water showing, what does the ceiling look like, has anyone been on the roof already. We use that to bring the right parts on the first trip.
- 2
Inspection and water test. Our technician gets on the roof and runs a controlled water test at low pressure, then works up. The goal is to find the actual entry point, not just the area where the drywall is wet. Water travels. The leak you see is rarely the leak you have.
- 3
Parts decision on paper. We quote OEM CGI components and quality aftermarket equivalents side by side when both exist, with the price difference stated. For warranty continuity on newer units, we recommend OEM. For out-of-warranty units, we will tell you honestly when a suitable aftermarket part does the same job for less. The decision is always yours, and it is always in writing before we touch anything.
- 4
The repair itself. Flashing, sealant, gaskets, new glass, hardware: whatever the job requires, we do it with the same care we would on our own homes. No shortcuts, no leaving the old failed sealant under the new bead because it is “good enough.” It is not.
- 5
Retest and cleanup. We water-test again after the repair and we do not pack up until it passes. We remove all debris, sweep up any glass fragments, and leave the roof cleaner than we found it.
- 6
The paperwork. You get a written description of what we did, what parts we used, and what is covered. If it is not in writing, it is not a guarantee - it is just a conversation.
What CGI Roof Repair Costs in Coral Gables
| CGI Repair Scenario | Typical Range |
|---|---|
| Flashing reseal on a curb-mounted roof lite | $350 - $650 |
| Weep channel cleaning and gasket replacement | $250 - $500 |
| Fogged IG unit replacement (per lite, residential size) | $800 - $1,900 |
| Full curb rebuild with new flashing and reset | $1,600 - $2,400 |
| Operable hardware replacement (arms, latch sets, crank) | $300 - $750 |
Price moves on three things: roof pitch and access, whether the unit is operable or fixed, and whether the curb itself has rotted framing that needs to be sistered. We quote a fixed number before we start and we do not change it mid-job. No surprise line items. Call (954) 507-3613 for an exact quote on your roof. Estimates are free.
Why Coral Gables Homeowners Call TruePane Windows & Doors for CGI Work
We are an independent CGI service provider, not a factory arm, which means we answer to you, not a corporate warranty department. Dale Kessler started this company in 2008 after years of watching out-of-true installs and voided warranties get passed off as normal, and the rule on the whiteboard has not changed since: if the pane is not true, the job is not done. Every repair carries our Done Right Promise. If it is not right, we come back and make it right. No paperwork fight, no fine print that covers neither.
We also work on PGT, CWS, ES Windows, and ECO Window Systems, which helps because many Coral Gables homes have a mix of brands across their roof and facade. One crew, one call, the whole roofline handled.
FAQs
CGI warranties generally cover the glass and frame, and legitimate repairs like flashing reseals or hardware replacement do not void them. Improper installations and non-spec parts do. We use OEM parts where warranty continuity matters and document everything in writing so you have a paper trail if you ever need to file a claim.
Most repairs are completed in a single half-day visit. Curbs that need rebuilding take a full day because the new framing has to dry before we set the unit. Call (954) 507-3613 and we will tell you what your specific job will take.
We replace the smallest part that actually fixes the problem. If the frame and curb are sound, a new IG unit or new flashing does the job for far less than a full replacement. We will tell you if replacement genuinely makes more sense, and we will show you the numbers both ways.
Yes. We source replacement IG units from Miami fabricators who match CGI’s original tints, thicknesses, and low-E coatings. The match is not “close enough.” It is spec’d.
A slow leak that has run inside a ceiling cavity can rot drywall and framing long before you see a stain. If you see a drip or a blister in the paint, the damage is already underway. Call (954) 507-3613 and we will get on the roof before it gets worse.
