CertainTeed Roofing in Northridge, CA | Ridge Cap Roof Repair
We provide independent CertainTeed roofing service across Northridge, including 91324, 91325, 91330, and 91327, and also offer CertainTeed in Encino. Most CertainTeed roofs in Northridge don’t fail because the shingle or tile gave out. They fail because the underlayment beneath them got cracked by the 1994 quake, or the north Valley sun baked the granule surface until the mat beneath started showing through. Noel Cardenas and our crew have been tracing those failures back to their actual source for years. Call (866) 361-0798 to schedule a roof inspection.
We work on CertainTeed Landmark, Presidential, and tile assemblies every week in Northridge, and we carry the full CertainTeed sales & service knowledge that comes from installing and repairing these systems across the north Valley. We’re not an authorized dealer or manufacturer representative. We’re a repair-first roofing crew that knows where CertainTeed roofs in this specific zip code tend to break, and we’ll tell you honestly whether the right call is a repair or a replacement.
Why Northridge Residents Choose Us for CertainTeed Service
Noel Cardenas grew up in the Muscoy neighborhood on San Bernardino’s northwest side, spending summers helping his uncle patch flat roofs before he ever thought of it as a career. He went through the construction trades program at San Bernardino Valley College, where the fundamentals of roofing systems and load paths got drilled into him before he ever touched a shingle field for pay. That background matters in Northridge, where the difference between a roof that lasts and one that leaks is usually in the details: the attachment, the underlayment lap, the flashing transition at a wall.
We inspect before we recommend. That’s not a slogan. When a Northridge homeowner calls about a ceiling stain or a missing shingle, we get on the roof, look at the whole assembly, and tell you what’s actually wrong. If the ridge cap is failing, the rest of the roof is already telling you something. You just have to know where to look.
Our service area covers Northridge service area including the ranch tracts off Reseda Boulevard, the two-story infill near CSUN, and the townhome clusters around the Northridge Fashion Center. We use genuine CertainTeed shingles, ridge cap, starter, and underlayment on every CertainTeed system we touch, so the color matches, the profile lines up, and the warranty stays coherent.

Common CertainTeed Roofing Problems We Solve in Northridge
- Baked, granule-stripped Landmark shingle fields. Northridge gets some of the hottest summer temperatures in the San Fernando Valley. Landmark shingles on 1950s-60s ranches off Reseda and Tampa have often baked past the point where a repair makes sense – granules gone, mat showing, shingles so brittle they crack when you try to hand-flex them. We’ll tell you straight when that roof is a replacement, not a patch job.
- Cracked or torn tile underlayment from the 1994 quake. This is the one that surprises people. A concrete tile roof in 91324 or 91325 can look completely intact from the ground, but the felt beneath the tile was cracked or displaced thirty years ago by the Northridge earthquake and never addressed. Water gets past the tile, hits that torn underlayment, and tracks down to your ceiling. The tile field looks fine. The leak is three decades old.
- Wind-lifted ridge caps and torn hip shingles after Santa Ana events. The north Valley’s dry Santa Ana winds hit exposed ridge lines hard, especially on two-story infill near CSUN and the Fashion Center. CertainTeed ridge caps and hip shingles that weren’t properly nailed or sealed get lifted, torn, or blown clear. After a wind event, the ridge is the first place we check.
- Flashing failures at wall and penetration details on ranch re-roofs. A lot of Northridge’s 1950s-60s ranch homes were re-roofed at some point without upgrading the original sheathing or nailer conditions. The flashing at walls, chimneys, and vent boots relies on that substrate, and when it rots or loosens, the CertainTeed shingles above can’t shed water properly.
- Underlayment failure under tile lift-and-relay work. When we lift concrete tile on a Northridge roof to replace felt, we often find the old underlayment was installed with a shortcut – short laps, wrong fasteners, or no secondary layer at the eaves. We re-lay over new CertainTeed Flintlastic SA or RoofRunner synthetic that’s actually spec’d for the exposure this roof gets.
Key Takeaways:
- We’re independent – not a CertainTeed dealer, but deeply familiar with Landmark, Presidential, and tile underlayment assemblies in Northridge.
- We inspect before we recommend. Repair when it makes sense. Replace when it doesn’t.
- Northridge’s 1994 quake damage hides under intact tile. We know to look for it.
CertainTeed Service in Northridge: What Local Conditions Mean for Your Equipment
Northridge sits directly over the San Fernando Valley’s north-ridge seismic zone, and that single fact shapes more of our CertainTeed work here than any other variable. The 1994 quake wasn’t just a headline – it cracked and displaced underlayment beneath thousands of tile roofs in 91324 and 91325, and many of those roofs have never been opened up since. A homeowner sees a ceiling stain years later, calls us, and we lift the tile to find original felt with a tear trace running straight back to that 1994 shaking, not to any recent storm. That’s the difference between a roofer who knows Northridge and one who just knows shingles. On a 1962 ranch off Reseda Boulevard, a homeowner called about a hallway stain with no visibly missing tile. We lifted the concrete tile on the affected slope and found the original felt cracked and displaced from the quake, water tracking down the torn lap. We replaced the underlayment on that run, re-laid the existing tile, and the stain stopped – without a single tile being replaced.
Add the north Valley’s heat to that equation and you get the full picture. Asphalt shingles in Northridge lose granules, curl at the rakes, and become brittle faster than they do closer to the coast. Tile roofs hold up to the sun but sit over underlayment that has been stressed by both UV and seismic movement. A CertainTeed roof in Northridge isn’t just a product – it’s a system that has been through specific, local abuse, unlike CertainTeed service in Van Nuys where conditions differ. We inspect for that abuse specifically.
CertainTeed Models & Products We Service in Northridge
We service the CertainTeed products most common in Northridge housing stock. On the 1950s-60s ranch tracts in 91324 and 91325, that’s usually Landmark architectural shingles – the workhorse of mid-century re-roofs. On the upscale infill and two-story remodels closer to CSUN and the Fashion Center, we see Presidential Shake and Presidential TL. Under tile, we install and service CertainTeed Flintlastic SA self-adhered underlayment for lift-and-relay work, plus XT25 and RoofRunner synthetic underlayments on full tear-offs.
When the existing roof is a CertainTeed system, we use genuine CertainTeed shingles, ridge cap, starter, and underlayment so the color and profile match and the assembly stays consistent. For flashing and metal that doesn’t affect the water-shedding system, we use quality aftermarket materials where they’ll hold up better. Stocking common CertainTeed profiles locally lets us turn most Northridge repairs around without waiting on a distributor order.

AfterCertainTeed Service Pricing in Northridge
CertainTeed roof work in Northridge varies by what’s actually wrong. Here’s what we typically see:
- Roof inspection: Free with any repair or replacement estimate.
- Tile underlayment replacement (lift-and-relay a slope): $18 – $28 per square foot, depending on tile condition and roof pitch.
- Flashing repair at wall or penetration: $350 – $900 per detail, depending on access and substrate condition.
- Ridge cap replacement on a CertainTeed shingle roof: $500 – $1,200 per ridge line, based on length and access.
- Full CertainTeed Landmark tear-off and re-roof: $8 – $14 per square foot of roof area, including underlayment and disposal.
- CertainTeed Presidential Shake/TL full replacement: $12 – $20 per square foot of roof area.
What drives the cost is what we find once we get on the roof. If the decking is original 1960s sheathing that’s still sound, the job costs less. If the 1994 quake or three decades of heat have compromised the substrate, the honest number reflects that. Our estimates are free, and we walk you through the findings before any work starts. Call (866) 361-0798 to schedule yours.

FAQs – CertainTeed Roofing in Northridge
Yes, and it’s more common in Northridge than most homeowners realize. The 1994 quake cracked and displaced underlayment beneath thousands of tile roofs in 91324 and 91325, and if that felt was never replaced, water can track through the tear and reach your ceiling even when every tile on top looks intact. We lift the tile, inspect the underlayment, and replace only what’s failed. Call (866) 361-0798 and we’ll trace the actual leak path.
CertainTeed Landmark shingles hold up as well as any comparable architectural shingle, but no asphalt product is immune to the north Valley’s UV and heat cycling. What matters more is the installation – proper fastening, correct nailing pattern, and underlayment that can take the temperature swings. We’ve seen CertainTeed fields in Northridge that lasted decades because they were installed right, and others that crumbled early because the crew skipped details. The installer matters as much as the product.
Start with the ridge cap and hip shingles, especially on two-story sections and any ridge line that faces the prevailing wind. Santa Ana winds in Northridge lift and tear shingles at the highest, most exposed points first. Then check flashing at walls and vents, which wind-driven rain can work behind. We’ll do a full wind-damage inspection and document what we find for your insurance claim if needed. Call (866) 361-0798 to schedule.
Yes, and we do it regularly in Northridge. If your concrete tile is sound but the felt beneath has failed – whether from 1994 earthquake damage, age, or a bad original install – we lift the tile in the affected section, remove the old underlayment, install new CertainTeed Flintlastic SA or RoofRunner synthetic, and re-lay the existing tile. It costs a fraction of a full tile replacement and keeps a good roof in service. If the tile itself is cracked or spalling, we’ll tell you that too.
Yes, those roofs are a big part of our Northridge work. We’ll inspect the original sheathing when we get under the shingles or tile, and we’ll tell you honestly what’s still holding up and what needs addressing before the new CertainTeed system goes on. Sometimes the decking is fine. Sometimes the 1994 quake or decades of heat have done damage that needs repair before we lay down underlayment. Either way, you’ll know before we start.
