CGI Construction in Mentone, CA | Stallion Contractors
We’re an independent construction crew that installs and repairs CGI sales & service products across Mentone, and the honest answer to what makes our work different here is simple: this town sits against the Crafton Hills in a wildfire-prone zone, so our CGI work is driven by fire code, ember resistance, and hillside drainage rather than generic tract-home repairs. If you need someone who understands Chapter 7A ignition-resistant assemblies and how they perform on Mentone’s slope lots, call us at (855) 600-3192. We’re not factory-authorized. We’re the crew that’s been on the ladders and in the attics here, fixing what the wind and heat actually do to these products.

Why Mentone Residents Choose Us for CGI Service
Ruben Montoya grew up in Colton, just down the road, and spent his early years watching tradesmen build houses that had to survive Inland Empire sun, wind, and chaparral conditions. That background shaped how we approach every CGI repair in Highland and every CGI job in Mentone. We don’t lean on a manufacturer certification. We lean on what we’ve learned pulling apart failed assemblies and rebuilding them correctly.
We stock a working inventory of CGI OEM parts for the components that matter most: fire-rated underlayments, ember-resistant vents, flashing, and edge metal. For non-critical trim and accessories, we’ll use aftermarket options when they meet or exceed CGI’s own specs. What a Mentone homeowner gets from us is a straight answer on whether a component can be repaired or should be replaced, based on its remaining service life and the fire exposure of the specific property. Not a pitch to sell a full roof when a targeted fix will hold.

Common CGI Construction Problems We Solve in Mentone
- Ember infiltration through CGI vented soffits. The standard vent screens on older CGI soffit installations degrade under Mentone’s summer UV and repeated heat cycles. Once the mesh loosens, wind-blown embers from the Crafton Hills chaparral can get drawn into attic spaces. We replace the screens with ember-resistant venting rated for the wildland-urban interface.
- UV degradation and color fading on CGI exterior trim and fascia. South- and west-facing exposures in Mentone take direct afternoon sun for five or six months straight. CGI trim can chalk, fade, and lose its surface integrity faster here than in valley-floor cities. We replace damaged sections with noncombustible or ignition-resistant materials where the fire code requires it.
- Wind uplift damage to CGI roofing underlayments and fasteners. Santa Ana events regularly push gusts past 60 mph through the Mentone foothills. Older CGI roofing installations often lack proper edge metal at rakes and eaves. Once the underlayment peels or the fasteners back out, water and embers follow. We re-secure edges and upgrade the perimeter details.
- Clogged CGI gutter systems causing drainage failure on slope lots. Mentone’s chaparral sheds leaves, twigs, and fine debris that clog CGI gutter screens fast. On east-side slope lots, a backed-up gutter sends water straight into foundations and erodes hillside soil. We clean, re-slope, and replace damaged gutter runs, then check the fascia behind them for rot.
- Manufactured-home CGI roofing tie-down and flashing failures. Mentone has a notable share of manufactured and mobile homes, and their roof assemblies behave differently under wind load than site-built framing. We repair CGI roofing on these structures with attention to the tie-down points and transition flashing that generic crews often overlook.
CGI Service in Mentone: What Local Conditions Mean for Your Equipment
Here’s the part most CGI service in Redlands or Loma Linda contractors don’t fully price in: Mentone is in the wildland-urban interface, which means the County fire authority applies ignition-resistant construction requirements that valley-floor cities don’t enforce with the same weight. Any roof replacement or repair here has to use Class A assemblies, ember-resistant vents, and in many cases fire-rated underlayments. That’s not optional. We saw this play out on a 1960s ranch home off Crafton Avenue, where the original ventilated soffits had let embers into the attic during a Santa Ana event. We replaced the entire assembly with a Class A fire-rated CGI system, switched the vents to ember-resistant models, and upgraded the fascia to noncombustible trim. The homeowner passed their insurance inspection the same week. If a crew gives you a Mentone roofing quote without asking about fire-rated underlayment, they haven’t done their homework on this town.
That’s the local reality of CGI construction in Mentone. It’s not just about the product. It’s about how the product has to perform when the wind pushes fire toward Crafton Hills-adjacent streets and the county inspector is checking the assembly details. We apply that same standard to every Mentone service area job we take, whether it’s a full roof replacement or a fascia repair on the south-facing side of the house.
CGI Models & Products We Service in Mentone
We work across the full CGI residential line that shows up on Mentone homes. That includes the CGI Builder Series for standard residential exteriors, the CGI Pro Series for heavier-duty installations that see more wind and sun, and the CGI Fire-Rated Series, which is what you’ll find more often on homes in the wildland-urban interface zones of this town.
Our parts approach is straightforward. For anything that touches the fire rating or the structural envelope – underlayment, venting, flashing, edge metal – we use OEM CGI parts to keep code compliance intact. For non-critical trim, gutters, and accessories, we’ll use aftermarket components when they match or beat the original spec. We keep the common Mentone-specific inventory on hand: ember-resistant vents, high-temp underlayment, and perimeter edge metal, because when a Santa Ana event tears through, the wait for a factory shipment isn’t something you want to explain to a homeowner with water coming in.

FAQs – CGI Construction in Mentone
Yes. CGI’s Fire-Rated Series includes Class A assemblies and components designed for wildland-urban interface zones, which is exactly what Mentone’s Chapter 7A-style enforcement requires on many lots. When we spec a roof here, we use fire-rated underlayment, ember-resistant venting, and noncombustible edge details as the baseline, not an upgrade. Call (855) 600-3192 if you want us to check whether your current assembly meets the local standard.
Santa Ana winds regularly exceed 60 mph through Mentone’s foothill corridors. The two failure points we see most are edge metal peeling away at rakes and eaves, and underlayment tearing once the perimeter is compromised. If your CGI roof was installed without proper edge fastening, it’s vulnerable. We can audit the perimeter and upgrade fasteners and flashing before the next wind season. Estimates are free at (855) 600-3192.
Yes. We’ve repaired ember intrusion damage throughout the Crafton Hills-adjacent streets of Mentone. The repair typically involves replacing the vented soffit screens with ember-resistant models, sealing any gaps where embers entered, and addressing whatever burn or heat damage affected the surrounding roof assembly. We’ll give you a straight answer on whether the whole roof needs replacing or a targeted repair will hold. Call (855) 600-3192 for an inspection.
You’re looking at $8,000 to $20,000 for a standard residential CGI roof replacement with fire-rated assembly details in Mentone, depending on square footage, slope, and whether we’re addressing manufactured-home or site-built framing. Metal roofs run higher, typically $15,000 to $40,000. The fire-rated underlayment and ember-resistant vents are non-negotiable on most Mentone lots, so those costs are built into the quote. Call (855) 600-3192 and we’ll give you an exact number for your house.
We do. Mentone has a higher proportion of manufactured and mobile homes than CGI repair in Calimesa and most surrounding cities, and their roof assemblies need attention at the tie-down points and transition flashing that site-built homes don’t always have. We’ve done CGI roof work on manufactured homes here and know what the County inspectors are looking for. Call (855) 600-3192 to schedule an estimate on yours.
