CGI Roof Repair in Sarasota: What to Know First
CGI roof repair in Sarasota runs most homeowners between $350 and $1,800 depending on whether we’re replacing a few damaged panels, resealing penetrations, or repairing structural damage from storm debris. We’re an independent CGI service provider, not a factory arm, so we fix what’s actually wrong rather than pushing a whole new system. Most CGI repairs take one visit, and we carry the common parts on the truck so we’re not leaving your roof open while we wait on a warehouse. If you’re a CGI owner in Sarasota, call (941) 267-0779 and Ed’s crew will give you a straight answer before we ever send a truck.

This page is for homeowners with CGI windows, doors, or associated roof penetrations and flashing who need honest repair work, not a sales pitch. We’ve been doing this since 2011.
How CGI Products Fail - and How We Fix Them
CGI makes some of the toughest impact-rated products in Florida. But “tough” doesn’t mean “never fails.” Here’s what we actually see on Sarasota roofs, especially after a rough storm season or a few years of salt air working on the hardware.
- Sentinel Series skylight flashing separation. The Sentinel line shows up on a lot of Sarasota homes built after 2010. The factory flashing does its job until a tree branch drags across it or a pressure washer hits it wrong. Then the seal breaks, water gets under the curb, and the ceiling stain follows. We pull the old flashing, inspect the curb for rot, install fresh flashing with proper sealant, and test it with a hose before we call it done.
- Estate Collection window-to-roof transition leaks. When CGI Estate windows sit in a gable or dormer that meets the roofline, the intersection is only as good as the original flashing job. Florida sun bakes the sealant, salt air attacks the metal, and the leak starts small. We remove the old work, install new step flashing where it belongs, and reseal the transition with an OEM-spec sealant so the repair doesn’t just buy you one more dry season.
- Hurricane-rated door header rot under roof overhangs. CGI doors are heavy, and when a roof overhang isn’t shedding water properly, the header above the door frame catches water. Wood rots, the door settles, and the operation gets stiff. We repair the header, reset the door, and correct the roof drainage above it so the same problem doesn’t come back next year.
- Corroded fasteners on CWS and CGI units. Stainless fasteners are standard on CGI products, but aftermarket screws wander into these systems all the time. A previous contractor uses a zinc screw, salt air eats it, and now you have a rust weep running down the frame. We replace with the right stainless fasteners and touch up the surrounding finish.
- Mullion joint failure on multi-window walls. When a wall of CGI windows meets a roofline, the mullion between units can leak if the original install missed a step. We pull the interior and exterior trim, reseal the mullion, and reflash the top course where it meets the roof. It’s a day’s work, and it stops the slow drip that’s been ruining your drywall.
What we don’t do is caulk over a problem and tell you it’s fixed. Salt air and afternoon storms don’t respect wishful thinking.
Our CGI Roof Repair Process
We’ve done enough CGI work across Sarasota that the process is second nature. Here’s what happens when you call (941) 267-0779:
- 1
You talk to a person. Not a voicemail tree. We get the symptoms, get your address, and schedule a visit. If it’s urgent, we adjust.
- 2
We diagnose on site. Ed’s crew walks the roof, inspects the affected CGI components, and gives you a real diagnosis with photos. No guesswork, no vague “we’ll know once we open it up” lines.
- 3
We price it before we touch it. Written, line-item, no change orders. You approve the number before anyone climbs a ladder. If we find something hidden, we call you and talk it through before adding a dollar.
- 4
We use the right parts. OEM CGI parts when availability and warranty control demand it. Quality aftermarket parts when they’re genuinely equivalent and we can explain exactly what you’re getting. We don’t put a bargain part in a premium product.
- 5
We repair, test, and clean up. Repairs get hose-tested or water-tested before we pack up. The roof looks like we weren’t there, except the leak is gone.
- 6
You get our 36500-Day Done Right Promise. If it’s not done right, Ed makes it right. That’s a century-long standard, and it means exactly what it says.
What CGI Roof Repair Costs in Sarasota
Nobody likes a vague number, so here’s the honest range based on what we’ve seen across Sarasota county:
- Reseal around a CGI skylight or vent: $350-$700
- Flashing repair at a roof-to-window transition: $450-$950

- Mullion reseal on a multi-window wall: $500-$1,200
- Storm damage repair involving multiple components: $1,000-$1,800+
What moves the price: how high the roofline is, how much water damage we find, and whether the prior work was done well enough to salvage. We don’t pad hours, and you’re never paying for us to learn on your roof. Call (941) 267-0779 and we’ll give you a written estimate. Free, upfront, and specific.

FAQs
No, not when the repair is done properly. As an independent CGI service provider, we follow CGI’s install and material specs so your warranty stays intact. If your warranty requires OEM parts, we use them and document everything. Call (941) 267-0779 and we’ll walk you through what your specific warranty says.
We schedule as quickly as the same week, and we keep the common CGI parts stocked locally so repairs aren’t waiting on freight. If you’re actively leaking, call (941) 267-0779 and we’ll tell you exactly when a tech can be there, not a five-day window.
We stock the typical failure points: flashing, sealants specified by CGI, stainless fasteners in common sizes, and interior/exterior trim pieces. Rare or model-specific parts get ordered directly, usually within three to five business days. We’ll tell you before we start whether the job depends on incoming parts.
On most roof-related failures, repair costs a fraction of replacement. A flashing reseal runs $350-$950, while replacing a CGI window or door starts well over $1,500 installed. We’ll only recommend replacement when the unit itself is compromised. Get a free estimate at (941) 267-0779 before you make that call.
