CGI Construction in San Francisco, CA | Copperleaf Contractors
We provide independent CGI metal cladding and roofing service across San Francisco, from the Outer Sunset to the Mission. CGI panels and standing seam profiles perform well here, but only when the install details account for fog-belt moisture and the city’s soft-story retrofit rules. We’re Copperleaf Contractors, led by Noel Cavanaugh, and we’ve spent years stripping CGI systems back to substrate on San Francisco’s damp, pre-war building stock. Call (833) 589-8173 for a free estimate on any CGI repair, re-clad, or roof scope.
Why San Francisco Residents Choose Us for CGI Service
Most contractors in San Francisco can order CGI panels. Few know what those panels do on a 1912 Edwardian with balloon framing and forty years of un-permitted remodel layers behind them. Noel Cavanaugh grew up in Sharp Park, where salt air and coastal moisture taught him early what buildings actually have to withstand. He studied construction technology at Skyline College, then spent the better part of two decades on residential and light commercial work up and down the San Mateo County coast before starting Copperleaf Contractors. His rule: know the site before you touch it.
That’s why our CGI work in San Francisco starts with reading the substrate, not the panel. We check what’s behind the cladding, how water is moving through the wall assembly, and whether the existing fasteners are OEM or aftermarket. Then we apply CGI’s published installation details to what’s actually there. Our CGI sales & service work covers everything from single-panel repairs to full re-clads and standing seam roof replacements.

Common CGI Construction Problems We Solve in San Francisco
- Gasket and fastener seal failure near the bay. In neighborhoods like the Marina, Dogpatch, and Bayview, salt air eats at the gaskets on CGI panel laps. Once the gasket hardens or cracks, wind-driven rain tracks behind the panel and starts working on the sheathing. We re-seal with CGI OEM gaskets and fasteners, not aftermarket trims.
- Moisture trapping over older sheathing. Fog-belt districts like the Sunset and Richmond stay damp for weeks at a time. CGI panels installed directly over old shiplap or lath without a drainage plane trap that moisture against the wall. We pull panels, assess the substrate, and re-install with the correct slip sheet or rainscreen detail.
- Oil-canning and fastener back-out on long runs. Thermal movement on CGI Architectural Series concealed-fastener panels shows up as waviness or popped fasteners when the clip spacing didn’t match the exposure. We re-detail runs with proper clip counts so the panels can move without distorting.
- Galvanic corrosion at penetrations. Pre-1940 buildings in the Mission, Noe Valley, and the Haight often have original galvanized or copper flashing. When CGI fasteners contact those dissimilar metals at vent pipes, window heads, or roofline transitions, corrosion starts fast. We isolate the metals and replace compromised fasteners with OEM-matched parts.
- Rotted substrate under intact panels. The panel can look fine while the wall behind it is failing. This is common on west-facing elevations where fog and wind load hit hardest. We don’t re-clad over rotted sheathing. We expose it, replace it, and then reset the CGI panels properly.
CGI Service in San Francisco: What Local Conditions Mean for Your Equipment
Here’s the part that makes San Francisco different from every other market we work in. The city’s Soft Story Retrofit Ordinance means any permitted ground-floor work on a pre-1940 wood-frame building can pull the entire structure into mandatory seismic upgrade scope. So CGI in Mission District on an Edwardian with an unpinned ground-floor garage isn’t just a cladding job. It can drag shear-panel installation, foundation bolting, and structural engineering into the project. No other city in the Bay Area triggers that. We’ve seen it happen on a 1912 Edwardian in the Mission where a crew was re-cladding an upper wall. Pulling the old redwood siding exposed balloon framing with no shear panels. The ground-floor garage permit already in play required us to address it, so we re-sheathed before setting CGI corrugated panels with OEM gasketed fasteners and a proper drainage plane. That wall now sheds the moisture the old assembly trapped. If you own a pre-1940 building in San Francisco, plan for this before you pull a permit. We do.
CGI Models & Products We Service in San Francisco
We work on the full CGI lineup: the Commercial Series metal wall panel system, Architectural Series concealed-fastener panels, corrugated metal siding profiles, and standing seam metal roof profiles. Our approach is simple. We use CGI OEM fasteners, clips, gaskets, and closure profiles wherever they’re available because aftermarket trims are where leaks start on metal cladding. When a panel run is sound but leaking at penetrations or laps, we repair and re-seal rather than re-clad. Replacement only gets recommended when the substrate behind the CGI is rotted or the panel itself is corroded through.
For San Francisco turnaround, we stock OEM gasketed fasteners, closure strips, and touch-up coating for common CGI colors. That cuts lead time on Visitacion Valley CGI service calls and repairs in nearby neighborhoods where a leak can’t wait three weeks for a parts order.

FAQs – CGI Construction in San Francisco
If the building is pre-1940 wood-frame and the CGI work requires a permit, the city can pull the ground-floor scope into the Soft Story Retrofit Ordinance. It depends on the specific building, the scope of the cladding work, and what permits are already on file. We can’t promise a retrofit won’t trigger, but we can tell you what we’re seeing on similar buildings in your neighborhood and plan the project scope accordingly. Call (833) 589-8173 and we’ll walk the site with you.
CGI standing seam performs fine in fog-belt conditions when the panel profile, fastener spec, and underlayment are matched to the exposure. The problem isn’t the metal. It’s the detailing. In neighborhoods like the Outer Sunset and Parkside, we spec gasketed fasteners and a proper drainage plane because the wall or roof assembly stays wet longer than it would with CGI service in Noe Valley or the Mission. Done right, CGI sheds water faster than the old composition shingles it replaces.
They will hide it until the rot spreads far enough to fail the fasteners. That’s why we don’t install CGI over questionable substrate. We expose the sheathing, determine what’s sound, replace what isn’t, and then set the panels. You’ll pay for the substrate work either way; doing it before the panels go on is cheaper than doing it after the wall starts moving.
Metal roof installation runs $17,700 to $47,200, and a full roof replacement with CGI standing seam typically lands between $9,440 and $23,600 depending on roof size, pitch, and whether the sheathing below needs work. San Francisco’s permit fees and the potential for seismic scope on older buildings add cost that a new-build roof in the East Bay wouldn’t carry. Call (833) 589-8173 for an exact quote, estimates are free.
Yes. We replace corroded fasteners with CGI OEM gasketed fasteners, re-seal laps and penetrations, and isolate any dissimilar-metal contact points that are driving the corrosion. Salt air near the bay works fast on the wrong hardware, so we don’t patch these with aftermarket parts. Call (833) 589-8173 and we’ll get eyes on the leak before it spreads.
