CGI Roofing: The West Palm Beach Owner’s Guide
We stock and install genuine and aftermarket-compatible parts for CGI metal roofing systems across West Palm Beach, with most repairs running $400-$1,800 installed and common fasteners, trim pieces, and panel sections available same-day from our local inventory. Homeowners usually discover a CGI part has failed after a storm passes through Palm Beach County and they spot daylight through a fastener hole, find a trim piece lifting at the rake edge, or notice rust streaking down a panel seam that was sealed five years ago. In the humid, salt-air environment along Flagler Drive and the Intracoastal, the galvanized coating on CGI fasteners often degrades faster than the panels themselves, which is why we see more fastener-related leaks than panel failures.
Which CGI Models This Applies To
CGI, or Corrugated Galvanized Iron, is not a single branded system but a family of profiles and gauges used across multiple manufacturers and import lines common in South Florida. The parts we stock and install cover the standard 26-gauge and 29-gauge corrugated profiles with 2.5-inch corrugation spacing, which is what you’ll find on most residential installations in West Palm Beach from the 1990s through the mid-2010s. To identify your exact part, check the panel edge for a gauge stamp, measure the corrugation pitch with a tape measure, and note whether your fasteners are exposed or concealed, a detail that changes the trim and closure specifications entirely.
We carry OEM-grade galvanized fasteners with the proper EPDM washer seal, as well as quality aftermarket equivalents from Marco Fasteners and Triangle Fastener Corporation that meet the same ASTM A153 hot-dip galvanizing standard. The aftermarket route saves roughly 15-20% on material cost without sacrificing corrosion resistance, which matters in West Palm Beach’s salt-laden coastal air. One compatibility gotcha we see regularly: imported CGI panels from the 2000s often used metric-thread fasteners that do not seat properly in standard UNC hardware, leading to stripped holes and future leaks if mismatched during a repair.
Signs Your CGI Roofing Is Failing

- Rust streaks running from fastener heads or panel seams. This indicates the zinc galvanizing has worn through, exposing bare steel to West Palm Beach’s humidity and salt air. Once rust appears, the fastener head is typically compromised and the seal beneath it has already failed.
- Trim pieces lifting or “oil-canning” at the edges. Thermal expansion in Florida’s intense sun causes CGI panels to move; when expansion joints or rake trim were installed without proper slip details, the metal fatigues and pulls fasteners loose.
- Daylight visible from inside the attic at panel overlaps. This means the side lap sealant has dried and cracked, or the closure strips have degraded under UV exposure, a common failure at year 12-15 in our climate.
- Water staining that follows a straight line across the ceiling. CGI leaks rarely spread randomly; they track along a corrugation valley or a single panel seam, which helps us trace the source to a specific fastener row or overlap point.
- Fastener heads sitting proud of the panel surface. The neoprene washer beneath has compressed permanently and no longer seals; in West Palm Beach, this happens faster where roof pitch is shallow and water lingers at the fastener line.

AfterReplacement Cost & What’s Included
CGI roofing repair in West Palm Beach typically falls between $400 and $1,800, with most single-section repairs landing in the $600-$900 range. The lower end covers fastener replacement and seal touch-up on a limited area; the upper end involves panel section replacement, trim fabrication, and substrate repair where rot has developed beneath a long-standing leak. Our quotes itemize parts and labor separately, and under Clause 1 of the Haven Standard, that written price is fixed before any work starts, no exceptions.
What drives the range: panel gauge and profile availability, whether matching material is still manufactured or requires custom fabrication, and the extent of decking damage beneath the failed area. We include a 365-Day Done Right Promise on all CGI repair work, backed by our documented photo record showing before, during, and after conditions. For full panel replacement, we also verify that the new section matches the existing profile within 1/32 inch to maintain proper water flow across the corrugation valleys.
DIY or Call Us?

A homeowner can safely inspect CGI roofing from the ground with binoculars or from a ladder at the eave, looking for the rust streaks, lifted trim, and proud fasteners described above. What you should not attempt: walking a corrugated metal roof without proper fall protection, removing and replacing fasteners on a slope, or cutting panel sections with power shears at height. The corrugation ridges are unstable footing, and a single misstep on a West Palm Beach tile or shingle roof below causes injury; on CGI, the panel itself can dent or deform underfoot, creating new leaks.
Where DIY goes wrong most often is fastener torque. Too loose, and the washer never compresses; too tight, and the panel dimples, trapping water. We use torque-calibrated drivers set to manufacturer spec, and we replace every fastener in a repair zone, not just the failed ones, because matching corrosion stages by eye is unreliable. If you’ve found the problem and want the number, call (561) 475-3903 and we’ll schedule a free estimate with a written price before any work starts.
FAQs
Properly maintained CGI roofing lasts 40-70 years in South Florida, but the fastener and seal components typically need attention at 15-20 years due to UV and salt-air degradation. The panels themselves often outlast two generations of hardware. Call (561) 475-3903 for an exact assessment of your system - estimates are free.
Small punctures or isolated corrosion spots can be patched with matching metal and proper sealant, but panels with creasing, widespread rust, or compromised structural gauge require replacement to maintain roof integrity. We evaluate each case and document our recommendation with photos. Call (561) 475-3903 for a written quote on either approach.
Most fastener and seal repairs are completed in a single visit of 2-4 hours; panel section replacement with trim fabrication typically requires a half day. We stock common CGI fasteners and closure strips on our trucks, so delays are rare in West Palm Beach. Call (561) 475-3903 to schedule - we deliver a written price before anyone picks up a tool.
Yes. We maintain inventory of 26-gauge and 29-gauge CGI-compatible fasteners, EPDM washers, foam closure strips, and ridge vent material at our West Palm Beach facility, with panel sections and custom trim available through our fabricator within 24-48 hours. Same-day repair is typical for fastener and seal failures. Call (561) 475-3903 to confirm availability for your specific profile.
Rowan Construction Group West Palm Beach is an independent service provider and is not affiliated with CGI or any specific panel manufacturer. We also stock and install parts for KraftMaid cabinetry, Cambria and Silestone surfacing, and additional building material brands across our seven trades.
