CertainTeed Roofing in San Gabriel, CA

CertainTeed Roofing in San Gabriel, CA | Van Nuys Roofing Co

We’re an independent CertainTeed roofing contractor serving San Gabriel, CA, and we handle everything from full CertainTeed shingle replacements to leak repairs on the town’s older Spanish and ranch-style homes. What sets our CertainTeed work apart here is simple: we’re just as comfortable re-laying brittle 1930s clay tile over new underlayment as we are installing a fresh Landmark architectural shingle roof. If your San Gabriel roof mixes original tile with CertainTeed asphalt, call (866) 321-6172 for a straight answer on what actually needs fixing.

We’re Van Nuys Roofing Co, and our crews know CertainTeed’s product lines inside out: Landmark, Presidential Shake, XT25/XT30, and the Roof Runner underlayment systems that go under them. Our CertainTeed sales & service experience spans decades across the San Gabriel Valley. Seven leading brands, one crew that knows them all.

Why San Gabriel Residents Choose Us for CertainTeed Service

San Gabriel isn’t a cookie-cutter suburb. Walk the older blocks near the Mission District and you’ll see 1920s Mediterranean bungalows with original clay barrel tile sitting right next to post-war ranch homes with asphalt shingle roofs. That mix means roofers here need to know both worlds, and most crews only really know one. Rick Dominguez grew up off Sepulveda Boulevard, a few blocks from the old Van Nuys Municipal Airport, and learned construction technology at Los Angeles Valley College before spending nearly two decades on rooftops across the San Fernando Valley. His crews have tore off and replaced hundreds of CertainTeed shingle roofs, and they’ve lifted just as many antique clay tile roofs to replace the dried-out felt underneath. That’s not a standard combination.

We inspect first, recommend second. If a CertainTeed roof in San Gabriel has granule loss on one slope but the rest is sound, we’ll tell you to repair the slope, not sell you a full tear-off. That’s how Rick operates: if it doesn’t need replacing, he’s not going to tell you it does.

Common CertainTeed Roofing Problems We Solve in San Gabriel

• Accelerated granule loss on west-facing Landmark roofs. San Gabriel sits inland where summer UV is relentless. West-facing slopes bake all afternoon, and CertainTeed Landmark shingles there lose granules years earlier than the north and east slopes. We see this constantly on 91775 homes. Often it’s a repair, not a replacement.
• Wind-creased XT25 three-tab shingles after Santa Ana events. Those old 1970s and 80s CertainTeed XT25 roofs get brittle with age. Santa Ana winds catch the tab edges, crease them back, and suddenly the roof leaks at every third course. Most leak calls we get in San Gabriel after a wind event trace back to exactly this.
• Valley and penetration leaks from dried-out underlayment. Dry-season debris piles up in roof valleys around San Gabriel. When the first winter rain hits, the backed-up water finds every dried-out underlayment seam and old pipe flashing. CertainTeed shingle roofs leak at valleys and penetrations long before the shingles themselves fail.
• Tile-to-shingle transition failures. Mixed roofs are common here because owners adding on or re-roofing kept the original clay tile on the front elevation and put CertainTeed asphalt shingles on the rest. The transition is where the crack de-bonds and opens a leak path. We fix these junctions regularly.
• Brittle clay tile that cracks during any shingle work. If your San Gabriel home has original S-tile and you need CertainTeed work done near it, a careless crew will crack tile just walking the roof. Our guys know how to lift, stack, and re-lay that tile without turning a shingle repair into a tile scavenger hunt.

CertainTeed Service in San Gabriel: What Local Conditions Mean for Your Roof

Here’s the thing about San Gabriel that owners in Rosemead or Arcadia don’t face nearly as often: much of the original housing stock here, especially in the 91775 zip code around the Mission District, was built between 1925 and 1955 with clay barrel tile roofs laid over the old hot-mop asphalt and felt systems. Those tiles are now 70 to 100 years old. They’re sun-baked and brittle. Lift one the wrong way and it snaps in half. So when a CertainTeed shingle roof needs full replacement on a home that still has original tile on the front slope, the job isn’t a simple tear-off. It’s a two-part operation: strip the shingle field, replace the underlayment and tie-in flashing, and then carefully lift and re-lay the original clay tile so the home keeps its historic character. Matching a faded, odd-sized vintage tile for a patch means checking salvage yards and specialty suppliers. A generic roofer who only does asphalt will tell you to replace the whole thing with shingles and be done with it. We’ll tell you what can stay.

On an older 91775 block near the Mission District, we tore off a failing CertainTeed Landmark roof and found that the owner wanted to keep the original barrel tile on the front slope where it tied into the shingle field. Our crew lifted the brittle S-tile, replaced the dried-out underlayment and reinstalled the original tile, then set new CertainTeed architectural shingles and matched flashing at the transition, sealing a valley that had been leaking into the ceiling for two winters.

CertainTeed Models & Products We Service in San Gabriel

We work on the full CertainTeed residential line. That includes Landmark architectural shingles in all colors and weights, Presidential Shake for homeowners who want the heavier wood-shake look without the fire hazard, and the older XT25 and XT30 three-tab shingles still protecting thousands of San Gabriel homes from the 1970s through the early 2000s. We also install and repair CertainTeed Roof Runner and SwiftStart underlayment and starter systems, which matter just as much as the shingles on top.

When a CertainTeed profile is still in production, we match OEM components: starter strips, hip-and-ridge caps, and underlayment. When a profile was discontinued 15 years ago, we source quality equivalent accessories that match the original color and exposure. We don’t push full re-roofs when a shingle repair plus a correct underlayment section will hold fine.

FAQs – CertainTeed Roofing in San Gabriel

Can you lift my original San Gabriel clay tile and re-lay it over new underlayment instead of replacing it?
Yes, we do this regularly on older San Gabriel homes, especially in the Mission District and surrounding 91775 blocks. The tile gets numbered, lifted, and stacked; we replace the underlayment and any bad flashing, then re-lay the same tile. You keep the original look and skip the cost of new tile. Call (866) 321-6172 and we’ll tell you if your tile is sound enough to survive the lift.

My CertainTeed Landmark shingles are losing granules on the sun-baked slope – do I need a whole new roof?
Not necessarily. In San Gabriel, west and south-facing slopes lose granules faster than any other exposure. If the shingles aren’t curling, cracking, or missing tabs, and the seal strips are still holding, you may have years left. We’ll inspect the slope and tell you straight whether it’s a repair or a re-roof. Estimates are free at (866) 321-6172.

Can you match CertainTeed shingles to a discontinued profile on my older San Gabriel roof?
If the profile is still in production, we match it exactly with OEM CertainTeed shingles and accessories. If it’s a discontinued XT25 or older three-tab, we’ll find the closest equivalent color and exposure. It won’t be a perfect match from three feet away, but it will be watertight and far less expensive than a full re-roof.

Why do my leaks always show up with the first winter rains?
Because San Gabriel’s summers dry out underlayment and fill valleys with debris. The first real rain saturates the debris, backs water up at the valley seams and pipe penetrations, and exposes every dried-out underlayment joint. By the time you see the ceiling stain, the water’s been working through for hours. If this happens every year, call (866) 321-6172 for an inspection before the next storm.

Do you repair the tile-to-shingle transitions where my CertainTeed roof meets clay tile?
Yes, and it’s one of the most common repairs we do in San Gabriel. The transition between a CertainTeed shingle field and original clay S-tile is a natural weak point. We replace the transition flashing, re-bed the edge tiles, and seal the junction so water can’t sneak behind either side.
