CertainTeed Roofing in Loma Linda, CA | Van Nuys Roofing Co
We provide independent CertainTeed roofing service across Loma Linda, from tile underlayment replacement on 1960s ranch homes to full Landmark shingle reroofs near the university, and we also handle CertainTeed repair in Colton. What sets our CertainTeed work apart here is the block-by-block pattern we see in the older tracts around Loma Linda University Health, where whole streets of original concrete tile roofs reach end-of-life together. If you need honest CertainTeed repair or replacement assessment, call (866) 321-6172 for a free estimate.
We’re not a CertainTeed authorized dealer, and we won’t pretend to be. We’re an independent roofing company that works across seven major material brands, including CertainTeed, which means our only loyalty is to what your roof actually needs. Our CertainTeed sales & service knowledge runs deep because we’ve torn off, repaired, and reinstalled these systems throughout the Inland Empire for years, and we know how they fail under Loma Linda’s specific conditions.
Why Loma Linda Residents Choose Us for CertainTeed Service
CertainTeed makes good products. Landmark architectural shingles, Presidential Shake, XT25 three-tabs, and their low-slope membranes all perform well when installed correctly and maintained. The problem most Loma Linda homeowners run into is finding a crew that understands how those products age in this specific inland climate, though the same challenge applies to homeowners needing CertainTeed repair in Grand Terrace. That’s where we come in.
Rick Dominguez, who runs Van Nuys Roofing Co, got his start in the trade through the construction technology program at Los Angeles Valley College and spent two decades on rooftops across Southern California before building this operation. The crew works across seven major material brands, CertainTeed included, so we don’t steer you toward a single product ecosystem, whether you need service in Loma Linda or CertainTeed service in Highgrove. We inspect first, recommend second.
For Loma Linda service area homeowners, that means straight answers about whether your CertainTeed roof can be repaired or has genuinely reached the end of its useful life. If it doesn’t need replacing, we’re not going to tell you it does.

Common CertainTeed Roofing Problems We Solve in Loma Linda
- UV-baked shingle curl on west-facing slopes. Loma Linda’s inland sun and the Santa Ana winds that funnel through the Cajon Pass corridor hit west-facing roof planes hard. CertainTeed Landmark and XT25 shingles lose their asphalt oils over time, tabs curl, and the mat dries out. It’s not a manufacturing defect, it’s climate. We see it constantly on homes west of the 215.
- Cracked concrete tile over dried-out CertainTeed underlayment. In the 1960s and 70s tracts around the university and hospital, original tile roofs often still look intact from the ground. The problem is underneath. The CertainTeed underlayment has dried, cracked, and stopped shedding water. The tile field looks fine while water is already reaching the deck. This requires a lift-and-relay, not a patch job.
- Flashing and vent boot leaks that show up after winter rain. Loma Linda gets relatively little rain, which means flashing failures go unnoticed for months. Then the first winter storm hits, and a ceiling stain appears. The shingles look fine. The flashing hasn’t. We find this constantly on aging CertainTeed assemblies.
- Ember-resistant detailing gaps on Class A assemblies. Wildfire risk in the foothills east of the freeway and near the university corridor is real. A Class A fire-rated CertainTeed assembly helps, but the rating alone doesn’t address ember entry at vents and valleys. We routinely correct those details on homes where the original install assumed fire rating was enough.
- Neighborhood-wide underlayment failure. This is the one that surprises newcomers. Whole blocks of original 1970s concrete tile roofs in Loma Linda share the same failing underlayment because they were built at the same time with the same materials. When we finish one house, the neighbor’s roof often shows identical problems.
CertainTeed Service in Loma Linda: What Local Conditions Mean for Your Roof
Loma Linda is a small, medically-anchored city. A large portion of the population works at Loma Linda University Health or lives here because of the Seventh-day Adventist community and the city’s reputation for healthy living. That shapes roofing demand in a very specific way. These are long-tenure owners. People stay in these homes for decades, and they reinvest in the same property rather than flipping it. The housing stock is dominated by mid-century to 1980s tract homes and ranch-style houses on the flat city grid, with newer custom homes climbing toward the foothills east of the 215. The older tracts, especially those within walking distance of the hospital and university, were largely built in the same construction window. That means the original concrete tile and CertainTeed underlayment systems all age on the same schedule. When one roof on the block shows dried-out membrane and cracked field tiles, the odds are high the whole block is approaching the same condition. Flat-grid cities spread out over decades of staggered construction don’t produce this pattern. Loma Linda does. It’s the single most useful thing to understand about CertainTeed roofing in this particular city.
On one of the established streets near Loma Linda University Health, our crew pulled and relaid the original concrete field tile on a 1970s ranch, replacing the dried-out CertainTeed underlayment underneath and swapping the cracked ridge tiles for matched replacements. Two doors down, the identical roof showed the same brittle membrane and hairline field cracks, so we documented both before the winter rains found them. That’s how roofing works in Loma Linda’s older tracts.
CertainTeed Models & Products We Service in Loma Linda
We work across the full CertainTeed residential lineup in Loma Linda: Landmark and Landmark Pro architectural shingles, Presidential Shake and Presidential TL, the older XT25 and Xtreme 25 three-tab lines, and the RoofRunner and Flintlastic low-slope membranes. For repairs on existing roofs, we use CertainTeed’s own accessory components, matching shingles, ridge caps, starter, and underlayment, so the repair integrates cleanly with the existing field. Where aftermarket flashing and boots outperform the original, we use those instead and we’ll tell you why. We keep the fast-moving CertainTeed repair materials on hand so Loma Linda jobs don’t stall waiting on a supplier order, and we carry the same inventory for CertainTeed repair in Redlands.

FAQs – CertainTeed Roofing in Loma Linda
Usually yes. The water stain typically means the CertainTeed underlayment under the tile has dried out and cracked, not that the tile itself has failed. We lift the tile, replace the underlayment, and relay the same tile. This is the single most common repair we do in Loma Linda’s older tracts, and it’s far less expensive than a full replacement. Call (866) 321-6172 and we’ll tell you what your roof actually needs after we inspect it.
Yes, and it’s not subtle. Coastal Los Angeles roofs get marine layer and moderate temperatures. Loma Linda gets intense inland UV and Santa Ana wind events through the Cajon Pass corridor. Both accelerate asphalt degradation. A Landmark roof that might last 25 to 30 years in a coastal climate can lose years off that in Loma Linda, especially on west-facing slopes. That’s why we tell homeowners here to inspect earlier, not later.
Because the homes were built in the same construction era with the same materials. The 1960s and 70s tracts around the university and hospital went up in concentrated waves, and the original CertainTeed underlayment systems all age together. When the membrane hits its failure point on one house, the neighbors are usually months or a few years behind. We see this pattern constantly in Loma Linda.
If you’re in the foothills east of the freeway or near areas with heavy brush exposure, yes. A Class A CertainTeed assembly is the right call. But we also correct what many installs miss: ember-resistant detailing at vents, valleys, and eaves. The rating alone is not the whole story. We’ll walk you through what a complete fire-resistant assembly looks like for your specific lot.
That’s exactly the conversation we’ll have, and it starts with an inspection. We don’t sell replacements. We document condition, tell you what’s repairable, and flag what’s past the point where more patches make financial sense. If your roof has several years left, we’ll say so. If the mat is drying out and you’re chasing leaks every winter, you’ll get a straight recommendation. Call (866) 321-6172 to schedule a roof inspection and we’ll give you an honest read.
