CGI Roofing: The San Antonio Owner’s Guide
If your CGI metal roof has a failing panel, a stripped fastener, or a leaking seam, we can match and install it. Typical installed repair and replacement work on CGI roofing in San Antonio runs $400 to $1,800 depending on what failed and how far the damage spread. Most owners discover the problem the same way: a brown stain on the ceiling after a heavy Texas downpour, or a panel that’s started to rattle when the wind kicks up off the Hill Country. You don’t need a whole new roof. You need the right part, matched to your CGI profile, installed by someone who knows how these panels lock together. That’s what we do.
Sawyer Remodel San Antonio is an independent service provider. We’re not affiliated with CGI, but we’ve worked on enough of their standing-seam and exposed-fastener profiles across Bexar County to know which parts fail first and what it takes to make the repair hold.
Which CGI Models This Applies To
CGI makes several metal roofing profiles, and the part you need depends entirely on which one is on your house. The main lines we see across San Antonio are the Standing Seam series, the Exposed Fastener series, and their specialty architectural profiles. The compatibility gotcha most homeowners hit: a 1-inch standing-seam clip from one CGI series will not seat properly on a panel from another series, even when both look close from the ground. You have to match the profile, not just the color.
We identify the right part three ways. First, we check the panel width and rib height with a profile gauge, which takes about two minutes on-site. Second, we look for the CGI stamp or sticker on the underside of a panel or on the original invoice paperwork. Third, we match the paint system. CGI uses specific Kynar 500 and SMP color formulas, and the San Antonio sun fades colors at a rate that makes a fresh off-the-shelf panel stand out against one that’s been up for eight years. We order the correct OEM panel or a verified aftermarket equivalent in the right gauge, and we tell you which one you’re getting and why before we order it.

Signs Your CGI Roofing Is Failing
- Water staining on ceilings or exterior walls after rain. This is usually a failed lap seam or a sealant bead that’s dried and cracked from San Antonio’s heat cycling. The leak is rarely where the stain shows up, because water travels along purlins and underlayment before it drops.
- Rattling or flapping panels in high wind. A panel that moves means the clips or fasteners have loosened or pulled out of the decking. It’s not just noisy. It’s a tear-off waiting to happen in the next serious gust, and once one panel lifts, the damage cascades.
- Rust streaks or pitting around the fastener heads. On exposed-fastener CGI profiles, the neoprene washers under the screws wear out in the South Texas climate. Once the washer cracks, water follows the screw shaft down into the decking, and the fastener starts to corrode.
- Visible gaps at ridge caps, valleys, or the drip edge. Metal expands and contracts with every hot afternoon and cool night. Over a decade, that movement loosens the trim. A gap you can see from the ladder means water has an open path in.
- White chalk or fading on the panel surface. This is the paint film breaking down. It’s cosmetic until it isn’t, because once the primer is exposed, the steel substrate starts to oxidize, and rust-through is only a few San Antonio rain seasons away.

AfterReplacement Cost & What’s Included
For the San Antonio market, CGI roofing repair work falls into clear bands. A simple fastener replacement or small sealant repair runs $400 to $800. Replacing one or two damaged panels with matching CGI profile stock runs $800 to $1,800 depending on panel length, profile complexity, and whether we’re pulling old material or working around solar mounts and HVAC penetrations. Full replacement of a CGI roof lands in the $15,000 to $40,000 range, but that’s a reroof, not a parts job.
Every estimate from Sawyer Remodel San Antonio is a written line-item price before work starts. You’ll see the cost of the panel or part, the cost of labor, and what the warranty covers. Our workmanship on every repair is covered by the 365-Day Done Right Promise: if it’s not done right, we make it right. You won’t find a surprise number on the final invoice, because the number we hand you before the tools come off the truck is the number you pay.
DIY or Call Us?
There are a few things an owner can safely check from the ground or a ladder: missing screw caps, obvious panel gaps, rust around fasteners, and corroded trim. But actually replacing a CGI panel or fixing a seam leak is not a weekend job, and it can go wrong fast. Panels are long, awkward, and sharp on the edges, and working on a metal roof after a rain is slicker than it looks. A fall from even a single-story San Antonio roofline means a hospital visit, and a panel that’s not re-seated properly against the existing profile will keep leaking.
Our crew brings the right profile-matching tools, fall protection, and the specific fasteners and sealants CGI profiles require. If you want to check the basics yourself before you call, go ahead. When you find something that looks off, call (432) 547-6806 and we’ll come correct it.
FAQs
CGI metal roofing panels are engineered for a 30-year lifespan, but San Antonio’s heat, hail, and UV exposure wear down fasteners, sealants, and paint film faster than the panel steel itself fails. Expect to replace washers and sealant beads every 8 to 12 years on exposed-fastener profiles. Call (432) 547-6806 and we’ll tell you what shape yours is in.
Small punctures and scratches can sometimes be patched with a color-matched sealant or a sheet-metal patch, but most hail dents, creases, and rusted-through sections require panel replacement to restore water-shedding performance. A patch that reads as good enough in January becomes a ceiling stain by May. We’ll give you an honest repair-versus-replace recommendation after we see the damage.
Most single-panel or small-section replacements are done in half a day, including removing the old panel, prepping the decking, and installing the new profile with correct fasteners and sealant. Larger repair work can stretch to a full day. We show up with the right parts and do the job in one visit.
We stock common CGI fasteners, clips, sealants, and trim pieces on the service truck at all times. Full panels are ordered per job after we confirm your exact profile and color, which keeps you from paying for a mismatched panel that was never going to look right. We’ll confirm availability and timeline when we write your estimate.
If your CGI roof is acting up and you want a straight answer, call (432) 547-6806. We’ll get a real person on the phone, schedule a look, and hand you a written price before any work begins. That’s how we run every job.
