CGI Roofing: The Austin Owner’s Guide
We stock and install CGI-compatible roofing parts across Austin, with most component replacements running $400 – $1,800 installed and roof replacement work landing between $8,000 and $20,000 depending on scope. If you’ve got a failed CGI fastener, a cracked panel, or a flashing detail that’s let go after a Hill Country storm, we can usually match the part and schedule the repair the same week. Most Austin homeowners discover the issue the hard way: a ceiling stain after a hard rain, daylight showing through a rusted fastener line, or a panel that’s started flapping in the spring wind.
CGI is a heavy-gauge metal roofing system, and in Texas that means it takes a beating from UV, hail, and thermal expansion. When a component fails, it’s rarely the panel itself. It’s almost always a fastener, a gasket, a flashing transition, or a trim piece that’s outlived its seal. That’s good news, because those are the parts we match and replace without tearing off the whole roof.
One thing up front: Mason Remodeling Co Austin is an independent service provider. We’re not affiliated with CGI, but we work with their product lines regularly and keep common components in stock or available within days.
Which CGI Models This Applies To

CGI’s roofing lineup in Austin spans a few distinct series, and the part you need depends on which one is on your house. The most common we see are the standing seam panels (including their snap-lock profiles), exposed fastener panels in 26- and 24-gauge, and their stone-coated steel lines. Each series uses different clip profiles, fastener specs, and trim dimensions, so a part from one line won’t always sit correctly on another.
The fastest way to identify what you have is to check the original paperwork from the install, or look for the manufacturer stamp on the underside of a panel or on a leftover piece in the garage. If you don’t have either, take a photo of the profile end-on and measure the rib height and panel width. A standing seam panel with a 1.75-inch rib takes different clips than one with a 1.5-inch rib, and that eighth of an inch matters when the wind picks up in March.
On the OEM-vs-aftermarket question: for exposed fastener panels, quality aftermarket fasteners with matching EPDM washers work fine in most Austin conditions. For stone-coated steel and standing seam, we lean OEM or direct-equivalent. The clip tolerances and paint-match are tighter, and the last thing you want on a $20,000 roof is a mismatched seam line catching sun differently than the rest of the field. We’ll tell you which way to go based on what’s actually on your roof, not what’s easiest for us to order.

Signs Your CGI Roofing Is Failing
- Water staining on ceilings or walls after rain. This is the symptom that sends most Austin owners looking for help. The panel is rarely the culprit. Usually it’s a deteriorated rubber gasket under a fastener head, or a flashing transition where the roof meets a chimney, skylight, or wall. The seal fails and water follows the fastener shaft down.
- Visible rust trails from fastener heads. Austin’s heat causes metal panels to expand and contract daily. That movement slowly grinds the washer seal, and once the seal goes, moisture sits against the fastener. Rust staining below the screw head is the tell. The fix is usually a fastener swap before the decking underneath gets involved.
- Panels lifting or rattling in the wind. Wind uplift in a March front can pull clips loose on standing seam if they weren’t set right originally, or if thermal cycling has worked them slack. You’ll hear it before you see it. Left alone, one loose panel becomes a peeled section.
- Granule loss from stone-coated edges. If you have CGI’s stone-coated steel and you’re finding granules in the gutter, the coating has started to let go. It’s more common on edges and valleys where water concentrates. This is a repair-early situation; once the steel is exposed, it’s on a faster clock in our humidity swings.
- Flashing pulling away at penetrations. The pipe boot, the chimney flashing, the valley metal, anywhere two different materials meet. The sealant dries out, the metal moves, and the gap opens. In Austin’s alternating wet-dry cycles, failed sealant at penetrations accounts for more leaks than any panel defect.

AfterReplacement Cost & What’s Included

| Scope | Typical Austin Range |
|---|---|
| Single CGI roof repair (fastener re-seal, small flashing fix) | $400 – $800 |
| Mid-size repair (flashing replacement, multiple fastener lines, valley work) | $800 – $1,800 |
| Full CGI roof replacement | $8,000 – $20,000 |
What drives the spread? Access, pitch, and whether the decking under the failed area is sound. A single-story ranch with a 4:12 pitch is a different labor reality than a two-story Mueller-area bungalow with a steep gable. Parts cost is usually modest; it’s the diagnosis, tear-off of the failed section, and making the repair look like it belongs there that takes time.
Every quote comes as a written price before any work starts. That includes parts, labor, and whatever disposal or cleanup applies. No change orders because we missed something on the estimate. The work is covered by our 365-Day Done Right Promise: if it’s not right within a year of completion, we make it right at no cost to you. And if a repair or install fails after we leave, the return visit is free.
DIY or Call Us?
Here’s the honest split. If you want to check your roof for signs of failure, walking your lot line with binoculars or checking the attic for daylight at the fastener lines is a safe, useful thing to do. What you don’t want to do is get on a metal roof to swap fasteners or peel flashing. Metal roofing is slick, Austin pitches vary, and a ten-foot fall onto limestone is not a gamble worth taking.
If the repair involves the panel world, the fastener pattern, or any flashing detail, call us. Tell me what’s wrong with it. We’ll figure out what it actually needs. We’ll send a background-checked, uniformed technician, you’ll get their name and photo before they arrive, and they’ll show a photo ID badge at the door. The price is in writing before work starts, and a live person answers our phone around the clock, every day of the year. Call (903) 623-1966 for a free estimate.
FAQs

CGI’s heavier-gauge metal systems are built for long service life, but realistic Austin performance is 30 to 50 years on standing seam, with exposed fastener systems often needing fastener maintenance at the 15 to 20 year mark because of thermal cycling and hail exposure. The panels themselves typically outlast the fasteners and sealants, which is why we focus repairs there. Call (903) 623-1966 if you’re not sure where your roof is in that timeline.
Yes, in most cases. If the panel is still structurally sound and the leak is at a fastener, seam, or flashing, we repair the failed component without replacing the panel. Full panel replacement only makes sense when the metal itself is torn, badly rusted, or the stone coating has failed across a large area. Call (903) 623-1966 and we’ll tell you what your roof actually needs.
Most single-issue repairs, like a fastener re-seal or a flashing replacement, take one visit and a few hours on site. If we’re replacing a panel section or working a full valley, it can take a day. We’ll give you the schedule in writing before we start. Estimates are free at (903) 623-1966.
We keep common fasteners, washers, sealants, and flashing profiles in stock, and we can source CGI-specific trim and panel sections within days through our supply chain. Alongside roofing, we stock components for other major brands including KraftMaid, Cambria, and Silestone, so one call covers more than just your roof. Call (903) 623-1966 and we’ll check availability for your specific CGI series.
