AfterCertainTeed Roofing in Santa Clarita, CA | Brennan Roofing
Brennan Roofing provides independent CertainTeed sales & service across Santa Clarita, from Canyon Country to Valencia, with written pricing before any work starts. Most CertainTeed roofs here fail for one of two reasons: Santa Ana winds breaking seal strips in the Newhall Pass corridor, or 1980s underlayment turning brittle under 150°F attic heat. We diagnose both, repair what still has life in it, and replace what doesn’t. Call (361) 320-9467 for a free estimate.
Why Santa Clarita Residents Choose Us for CertainTeed Service
We’re not a factory store. We’re an independent crew that has spent years pulling apart CertainTeed Landmark shingles, XT 25 organic mats, NorthGate tile, and Presidential Shake across the Santa Clarita service area, and we know how each of those systems fails in this specific climate. Travis Oakley, our owner, trained in building construction technology at Los Angeles Trade-Technical College and spent close to two decades doing production and repair work across LA County. He still walks his own inspections. That means when we tell you a CertainTeed roof has five years left or needs full replacement, the answer comes from someone who actually climbed up and looked, not from a sales script.
We carry CertainTeed OEM shingles and accessories when they match the existing roof, and we stock quality aftermarket underlayments, flashing, and fasteners that meet or exceed the Santa Clarita Roofing Company wind-uplift requirements. Same crews, same standard, same written price on every job. Our technicians are background-checked and arrive in uniform. You know who’s on your roof.
Common CertainTeed Roofing Problems We Solve in Santa Clarita
- Wind uplift on CertainTeed Landmark shingles. The Santa Ana corridor through Soledad Canyon and Newhall Pass regularly produces 60+ mph gusts. If a Landmark roof was originally installed with four nails per shingle instead of six, seal strips break and shingles peel back. We see this most often on homes built in the 1990s when fastening schedules were looser.
- Premature aging of CertainTeed XT 25 organic-mat shingles. Santa Clarita’s UV exposure is relentless, and attic temperatures above 150°F cook organic mats from below. The result is granule loss, exposed mat, and shingles that crack when you bend them. Once the mat is exposed across more than a third of the roof, patching becomes a losing game.
- Underlayment failure beneath CertainTeed NorthGate and Presidential tile. In Valencia’s older tracts, original 1980s concrete tile roofs often have felt that’s now brittle and crumbling. Santa Ana winds drive rain horizontally under the tiles, water travels along the decking, and leaks show up far from the actual breach, often as ceiling stains in interior hallways.
- Flashing and vent boot deterioration. Heat cycles in Santa Clarita cause sealant to crack and nails to back out around chimneys, skylights, and plumbing vents. These leaks are frequently misdiagnosed as shingle failures. We trace the water to the penetration first.
- Tile cracking from thermal shock. Hot days followed by cool nights stress concrete tile. When a tile cracks and shifts, the underlayment beneath it takes direct water. In older Valencia roofs where that underlayment is already brittle, a single cracked tile can be the starting point for a hallway ceiling stain.
CertainTeed Service in Santa Clarita: What Local Conditions Mean for Your Equipment
In Valencia’s older tracts, the original CertainTeed concrete tile roofs from the 1980s have a failure pattern you won’t find in newer neighborhoods or coastal cities. The tile itself often looks fine. The problem is underneath. Original felt underlayment was rated for roughly two decades. Thirty-plus years of 150°F attic heat bakes it into something that crumbles when touched. When a Santa Ana wind event drives rain horizontally, water gets under the tiles at the roof edge, travels laterally across the decking, and drips through the failing felt far from where it entered. Homeowners see a water stain on an interior hallway ceiling and assume a roof leak near that spot. It’s almost never there. In Valencia’s Northbridge tract, our tech inspected a 1987 CertainTeed concrete tile roof after the homeowner noticed a water stain on the hallway ceiling, far from any obvious roof damage. We traced the leak to failed underlayment beneath intact tiles, where wind-driven rain had traveled laterally. We replaced the brittle felt with a high-temp self-adhering membrane before resetting the original tiles. The repair stopped the leak and restored the roof without a full tile replacement. That’s the difference between treating a symptom and finding the actual breach. A roof that’s squared away doesn’t need a sales pitch.
CertainTeed Models & Products We Service in Santa Clarita
We work on the CertainTeed lines most common in Santa Clarita’s 1980s and 1990s tract housing: Landmark architectural shingles, XT 25 three-tab shingles, NorthGate concrete tile, and Presidential Shake. We use CertainTeed OEM shingles and accessories when they’re available and match the existing system. When OEM tile isn’t produced anymore or a discontinued color can’t be matched, we source quality aftermarket underlayments, flashing, and fasteners that meet or exceed current wind-uplift code for the Newhall Pass corridor. We stock common fasteners, high-temp underlayment, and flashing locally for faster turnaround on Santa Clarita jobs.

FAQs – CertainTeed Roofing in Santa Clarita
After a wind event, look for shingles on the ground, lifted edges along the rake, or tabs that don’t lay flat. On the roof, broken seal strips show as shingles that lift easily when you run a flat bar under them. If the roof is 20+ years old and you’re seeing granule loss in the gutters or exposed mat, the wind didn’t create the problem, it exposed it. Call (361) 320-9467 and we’ll get on the roof and tell you what’s actually failing.
Because the leak is almost certainly in the underlayment, not the tile. Your roof doesn’t rely on tile to stay watertight. The underlayment is the waterproof layer. In 1980s Valencia tracts, that felt is often brittle and failing. Wind-driven rain gets under the tiles and travels horizontally before dripping through. The leak shows up far from the breach. We trace the water path and replace the failed felt without disturbing the tiles.
No. If the tiles are intact and still have service life, we remove only the section over the failed underlayment, replace the membrane, and reset the original tiles. We only recommend full tile replacement when tile cracking or spalling is widespread. The free estimate tells you which situation you’re in. Call (361) 320-9467 to schedule yours.
Six nails per shingle, minimum, on any CertainTeed shingle roof in the wind corridor. We also verify starter strip nailing and rake-edge fastening, because those are the first points to fail in 60+ mph gusts. If we’re repairing a roof that was originally installed with four nails, we check the seal strips and upgrade fastening on any field we touch.
It depends on the membrane age and the number of existing patches. A single split or penetration failure can be patched. If the membrane is brittle with multiple alligator cracks, repair money is wasted. Our stance is the same on flat roofs as anywhere: repair localized damage when the rest of the system has life, replace when it doesn’t. Call (361) 320-9467 for an honest read on your roof.
