CGI Construction in Highland, CA | Toolbox Contractors
If you own a CGI-built home in Highland, the question isn’t whether we service CGI construction. It’s whether the crew you call understands how Highland’s WUI fire code and foothill drainage change the repair. We do. Toolbox Contractors handles re-roofs, additions, and structural repairs on CGI homes across the 92346 zip code, and our crews know the difference between a flatland fix and what a Highland foothill property actually needs. Call (855) 382-3257 for a free estimate.
Why Highland Residents Choose Us for CGI Service
Norm Castellano grew up in the Muscoy area just northwest of CGI in San Bernardino, where half the houses on his street were always mid-project and the other half needed to be. Since then, he’s spent two decades working on residential construction across the Inland Empire, and his Toolbox Contractors crew has untangled more than a few CGI messes that other contractors walked away from. Tell me what you’ve got and I’ll tell you what it actually needs.
We’re an independent contractor, not a CGI dealer or authorized service provider. That’s an advantage when you’re dealing with a 1960s stucco-over-wood-frame tract home or a detached garage on a graded foothill pad. We’re not married to OEM-only fixes. We source OEM-spec framing connectors and flashing where the original CGI assembly demands them, and we use aftermarket roofing and weather-barrier products where they genuinely outperform what was there before. For Highland homeowners, that means the right material for the actual condition, not a brand-loyalty tax.

Common CGI Construction Problems We Solve in Highland
CGI-built homes from the 1960s and 70s are everywhere in Highland, and they fail in predictable ways. Here are the five we see most often on east-side tract homes and semi-rural foothill lots:
- Hairline stucco cracking and moisture staining after Santa Ana wind cycles. Most original CGI stucco-over-wood-frame walls were built without a proper weep screed and drainage plane. When the dry winds hit in the fall and winter storms follow, you’ll see the cracks open up and moisture wick behind the stucco. We install the drainage assembly the original build missed.
- Roof deck and underlayment failure at flashings and valleys. The first heavy rain after a dry season exposes every weak flashing point on a CGI roof. Original 1960s-70s underlayment was never designed for fifty years of Highland’s hot inland summers followed by sudden downpours. We strip back to the sheathing, replace what’s rotted, and rebuild the flashing lines.
- Ponding water and blistering on flat or low-slope roof sections. Enclosed patio conversions and room additions on CGI homes frequently have low-slope roofs that hold water. In Highland’s summer heat, that ponding water cooks the membrane until it blisters and splits. We regrade the slope where possible and install a properly rated low-slope assembly.
- Detached garage and shop slab cracks after winter runoff. On foothill lots with graded pads, the original compaction and drainage work on CGI outbuildings often wasn’t enough. After the first big winter storm, you’ll see slab cracks and wall separation where water undermined the pad. We diagnose the drainage miss first, then fix the slab.
- Additions and patio enclosures that were never properly tied into the original framing. The most common CGI failure isn’t the original house. It’s the addition someone bolted on in the 80s or 90s without addressing load path or roof drainage. We tie the addition back into the original assembly the right way.
CGI Service in Highland: What Local Conditions Mean for Your Equipment
Here’s the thing nobody tells you until you’ve pulled three permits in this city: Highland sits at the foot of the San Bernardino Mountains in a high-fire-severity zone, and your CGI re-roof or addition has to pass ember-resistant detailing and defensible-space scrutiny that the same CGI house down the hill in San Bernardino or Redlands would never face. A roof that would sail through inspection in the flats gets flagged here because of the wildland-urban-interface code. The city’s inspectors look at exterior materials on a CGI addition the way flatland crews never see: they want Class A roof assemblies, they want venting details that stop embers, and they want the drainage plane detailed so wind-driven rain can’t get behind the stucco. If you’re planning a CGI re-roof or addition on one of the foothill lots along the base of the mountains, the code conversation starts before the material conversation. We schedule our Highland exterior work around the fire season and the Santa Ana wind forecast because working on a torn-off roof deck during a red-flag warning isn’t just risky. It’s an invitation to redo the job. See our broader Highland service area coverage to understand where we work.
On a 1960s CGI stucco tract home off the flatter east side of Highland, our tech traced a leaking patio enclosure to a failed low-slope roof section and a missing weep screed above the foundation. We rebuilt the flashing and drainage plane, installed a Class A roof assembly that meets the city’s WUI exterior expectations, and the homeowner’s ceiling stains stopped after the first winter storm.
CGI Models & Products We Service in Highland
We service the full range of CGI construction we see across Highland’s 92346 zip code. That includes the stucco-over-wood-frame tract homes built across the east side in the 1960s and 70s, the detached garages and shop buildings on semi-rural foothill lots, the room additions and enclosed patio conversions that got tacked on over the decades, and the mid-century homes that need full re-roof and exterior envelope packages.
For parts, we match OEM-spec framing connectors, flashing, and stucco accessories where the original CGI assembly calls for them. We keep common roofing transitions, flashing profiles, and stucco weep components stocked locally for fast turnaround on Highland jobs. Where the original CGI material is no longer the best available option, we’ll tell you straight and use a quality aftermarket product that outlasts what was there.

AfterCGI Service Pricing in Highland
Pricing in Highland is driven by three things: the age of the original CGI assembly, the condition of the roof deck or stucco drainage plane, and whether the project falls under the city’s WUI exterior requirements. A straight re-roof on a 1960s tract home costs less than a re-roof plus sheathing replacement plus ember-resistant venting upgrades on a foothill lot. Here’s where our recent Highland work has landed:
| Service | Typical Cost Range |
|---|---|
| Roof Replacement | $8,000 – $20,000 |
| Roof Repair | $400 – $1,800 |
| Metal Roof Installation | $15,000 – $40,000 |
| Home Addition | $45,000 – $130,000 |
| ADU Construction | $90,000 – $220,000 |
Our free estimates include a written line-item quote, a walkthrough of what the WUI code means for your specific property, and a straight answer on repair versus replace. Call (855) 382-3257 to schedule at your property.

FAQs – CGI Construction in Highland
Yes, we can match the original CGI stucco assembly and roof detailing closely enough that the addition looks like it was always there. The bigger question is whether you want us to match the original, or improve it. The original 1960s CGI stucco-over-wood-frame assemblies often lacked proper weep screed and drainage planes, and those missing pieces are exactly what cause the hairline cracking and moisture staining we see across Highland’s east-side tracts. When we add onto a CGI home, we match the aesthetic but build the drainage plane the way the original should have been built. Call (855) 382-3257 to talk through your addition and get a free estimate.
It can, if your house sits in a WUI zone or the inspector requires ember-resistant venting and a Class A assembly we wouldn’t have to install on the same CGI roof down the hill in CGI in Redlands. The additional cost is usually in materials, not labor: upgraded underlayment, ember-resistant vent screens, and sometimes a stucco exterior detail where the roof ties into the wall. For a standard CGI tract home on the flatter east side, the premium is modest. On a foothill lot along the base of the mountains, it can add a few thousand. We’ll show you the exact line items before you sign. Call (855) 382-3257 for a written quote.
Yes, in most cases. The detached CGI garages and shops we see on Highland’s graded foothill pads were built on compacted fill that settles and drains unpredictably. When winter runoff from the foothill drainages moves through the lot, it erodes the material under the slab edge, and the slab cracks or separates from the wall. The fix starts with drainage, not concrete. We regrade the slope, add a swale or retaining detail where needed, then address the slab. Call (855) 382-3257 and we’ll diagnose it on site with a free estimate.
Yes, you can convert a CGI enclosed patio into a permitted addition in Highland, but the permitting path depends on when the patio was enclosed and whether the roof structure and foundation were built to code. Many CGI patio enclosures in Highland were done without permits in the 80s and 90s, and the city will not grandfather substandard structural work. We pull the permits, fix the roof slope and drainage, tie the framing back into the original CGI structure, and bring the project up to current Highland building and WUI requirements. Call (855) 382-3257 and we’ll walk the project with you.
For Highland’s specific conditions, a standing-seam metal roof or a properly installed Class A composition roof with high-wind rating both hold up well. Metal handles the Santa Ana wind gusts better and reflects the inland summer heat, but it costs more upfront. A quality composition roof with the right underlayment and flashing details will do the job on most CGI tract homes and costs less. On a foothill lot where ember intrusion is the bigger threat, either roof works as long as the venting and edge detailing are WUI-compliant. Call (855) 382-3257 and we’ll walk you through the trade-offs for your specific CGI home in Highland.
