Why Boulder City Residents Choose Us for CGI Service
We’ve been working with CGI products in Boulder City long enough to know exactly how they behave under Mojave Desert sun. That’s not manufacturer training. It’s field experience. Reed Calloway, our owner, grew up in the Whitney neighborhood of Paradise and spent years on job sites before founding Ellsworth Contractors. He’s seen what happens when a roof gets installed without accounting for Boulder City’s altitude, UV intensity, and those 30-degree overnight temperature swings in spring and fall. If you need CGI repair in Whitney or nearby areas, our team brings that same field-tested expertise.
We use CGI OEM components where waterproofing matters most: underlayment, flashing, valley lining. For fasteners and sealants, we source aftermarket options that meet or exceed OEM specs for desert conditions. That’s not cutting corners. It’s knowing which parts fail first in this climate and choosing materials that hold.
Our full-scope capability matters here too. When your CGI roof needs work, we can handle the stucco repair, fascia replacement, or gutter work that often rides along. One crew, one schedule, one accountable contractor. That’s how we’ve always run projects in Boulder City.

Common CGI Construction Problems We Solve in Boulder City
- Granule loss and brittleness on CGI ShingleMaster roofs. After 8 to 10 years of Boulder City’s relentless UV exposure, asphalt shingles start shedding granules. You’ll see them collecting in gutters and downspouts. Once the granule layer is gone, the asphalt mat bakes and cracks. We inspect ShingleMaster roofs across 89005 and 89006 and give you a straight answer on repair versus replacement.
- Thermal cracking on CGI TileGuard clay tile installations. Boulder City’s daily temperature swings expand and contract clay tiles by millimeters. Over a decade, that adds up to cracked tiles and slipped courses. We hand-match replacement tiles to your existing profile and color, which matters enormously here because the Historic District won’t approve mismatched patches.
- Underlayment failure beneath reused 1930s clay tiles. A large share of Boulder City homes still carry their original clay tile. The tiles survive. The old felt underlayment beneath them doesn’t. We’ve opened roofs where the underlayment crumbled to dust. Our fix is CGI TileGuard or WeatherLock synthetic underlayment, installed before the original tiles go back down.
- Wind uplift and fastener back-out on CGI MetalSeam panels. Mojave gust patterns aren’t gentle. Metal roofing installed without proper clip spacing will work fasteners loose over time. We re-torque, replace backing clips where needed, and correct the spacing so your MetalSeam roof stays put through the next wind event.
- Historic District design-review rejections. This one’s specific to Boulder City. Homeowners try to swap in a modern tile profile, the application gets denied, and the project stalls. We prepare CGI product specifications and physical samples that match the 1930s Spanish Colonial vocabulary the review board expects. Approval usually follows.
CGI Service in Boulder City: What Local Conditions Mean for Your Equipment
Boulder City sits at roughly 2,300 feet in the Mojave Desert, and summer highs above 100°F start punishing roofing materials in May and don’t stop until October. The UV index here is brutal, and it’s compounded by the city’s Historic District rules. Nearly every home sits within a design-review overlay that requires exterior changes visible from the street to match the original 1930s-40s character. That means when a CGI ShingleMaster roof on a 1938 Spanish Colonial home off Nevada Way fails, you can’t just pick any replacement product. You need a material and profile that the review board will approve. We’ve walked dozens of Boulder City homeowners through that process, including the paperwork and physical material samples, as any qualified Boulder City General Contractor should. It’s the part of the job no one tells you about until the permit application comes back.
On one 1938 Spanish Colonial on Nevada Way, our crew replaced a failing CGI ShingleMaster roof that had lost most of its granules after 12 years of desert sun. We upgraded to CGI TileGuard underlayment beneath the original clay tiles, hand-matching replacement tiles to the Historic District’s design standards, and finished with new CGI WeatherLock underlayment in the valleys. The homeowner passed design review without a single revision, and that roof is now rated for another 30 years of Mojave summers.
CGI Models & Products We Service in Boulder City
We install, repair, and replace the full CGI residential roofing line in Boulder City: CGI ShingleMaster asphalt shingles, CGI TileGuard clay tile underlayment, CGI WeatherLock synthetic underlayment, and CGI MetalSeam standing seam panels. We’re an independent construction firm. We’re not manufacturer-authorized, and we don’t claim to be. What we have is 15 years of hands-on work installing and repairing these products across Boulder City’s housing stock, including the small 1930s homes and compact commercial buildings that dominate the 89005 zip code. We also provide Enterprise CGI service for clients in that growing area.
We stock common CGI-compatible flashing, valley metal, and synthetic underlayment locally, so most Boulder City repairs don’t wait on a distributor shipment. When a review board sample is needed, we pull it from stock and hand-deliver it to City Hall.

AfterCGI Service Pricing in Boulder City
CGI roofing work in Boulder City falls into predictable ranges. The age of your home, the condition of the existing deck, and whether you’re in the Historic District all move the number.

| Service | Typical Range in Boulder City |
|---|---|
| Roof Replacement | $8,000 – $20,000 |
| Tile Roof Repair | $600 – $2,500 |
| Metal Roof Installation | $15,000 – $40,000 |
| Roof Repair | $400 – $1,800 |

FAQs – CGI Construction in Boulder City
Yes. If your home sits within the Historic District overlay, which covers most of Boulder City, any roof replacement visible from the street must match the original 1930s-40s profile and color. We prepare material samples and CGI product specs for the review board so your application moves through without revisions. Call (888) 445-6077 and we’ll tell you whether your property is in the overlay before you spend a dollar on materials.
Boulder City’s sun strips asphalt shingle granules faster than almost any climate in Nevada. After 8 to 10 years, a ShingleMaster roof here will show significant granule loss, brittleness, and cracking along the edges. That’s a material reality of intense UV at 2,300 feet, not a defect. We inspect roofs across 89005 and 89006 and tell you honestly whether repair or replacement makes more sense for your remaining roof life.
Yes. We hand-match replacement clay tiles to your existing profile and color, then install them over CGI TileGuard underlayment. This is the standard process for Boulder City homes with original tile roofs, because the Historic District will reject mismatched patches. We keep physical samples on hand so you can see the match before we order.
For the small single-story homes on 25- to 50-foot lots that dominate Boulder City, we typically recommend CGI ShingleMaster asphalt shingles for budget-conscious replacements, or CGI TileGuard underlayment with restored original clay tiles when the home’s character matters. A CGI MetalSeam standing seam roof is also a strong option if you want a 40-plus-year lifespan and can handle the higher upfront cost. Call (888) 445-6077 and we’ll bring samples to your property and talk through what each option costs on your specific roof.
We do. Monsoon season in Boulder City brings sudden, violent wind and rain, and we take emergency calls for flooded ceilings, lifted flashing, and wind-damaged CGI roofs. Call (888) 445-6077 the moment you see a leak and we’ll get a crew to your Boulder City property as quickly as the schedule allows.
