CertainTeed Roofing in Sierra Madre, CA | Van Nuys Roofing Co
We provide independent CertainTeed roofing service across Sierra Madre, CA, from tear-off inspections to full Landmark and Flintlastic installations. The one thing that makes our CertainTeed work here different is that we’ve spent enough time on Sierra Madre roofs to know the deodar cedar and oak canopy shapes nearly every failure mode. We inspect first, recommend second, and if you need a straight answer about whether that CertainTeed roof can hold another season, call us at (866) 321-6172 for a free estimate.
Why Sierra Madre Residents Choose Us for CertainTeed Service
Most roofers in the foothills push one brand. We work with seven: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That matters when you own a CertainTeed roof in Sierra Madre because we’re not trying to steer you into anything else. We know Landmark architectural shingles, Presidential Shake, Presidential TL, and Flintlastic membrane inside and out because we’ve installed and repaired every one of them on the streets up here, from the Craftsman bungalows near Baldwin Avenue to the post-war ranches back up toward the mountains. Rick Dominguez, our owner, learned the trade the hard way: two decades on rooftop tear-offs and repairs across the San Fernando Valley, then a construction technology program that taught him what actually fails and why. His dad was a finish carpenter, so standing by your work was never optional. And if a Sierra Madre roof doesn’t need replacing, we’re not going to tell you it does.
Styles & brands we work with
Common CertainTeed Roofing Problems We Solve in Sierra Madre
- Valley and gutter damming from cedar and oak litter. Deodar needles don’t wash off like pine. They mat down in roof valleys, trap moisture against the shingle edges, and rot the fascia behind them. We clear valleys, replace the damaged CertainTeed shingles, and re-flash so water moves again.
- Dry rot in sheathing under old shake-to-Landmark conversions. Those early-1900s bungalows often had original wood shake buried under a later CertainTeed shingle layer. Decades of sun-cracked shake hid soft decking until tear-off. We’ve seen it often enough that we check for it before quoting any re-roof.
- UV granule loss on south and west slopes. Sierra Madre sun is relentless. CertainTeed shingles on those exposures lose granules faster, get brittle, curl, and then lift when a Santa Ana wind hits. Replacement of shaded-side shingles is rarely needed; south and west planes wear like they’re on a timer.
- Leaks at step and valley flashing on ranch additions. Post-war ranches here often have a low-slope tar-and-gravel section meeting a shingle field. Winter rain drives into failed flashing joints, and the membrane fails where the homeowner can’t see it. We re-detail those transitions with proper metal and underlayment.
- Tab lifting after Santa Ana events. High wind up against the foothills catches any shingle with compromised sealant. We inspect after big wind events, reseal or replace lifted tabs, and tell you honestly if the underlying deck is still sound.
CertainTeed Service in Sierra Madre: What Local Conditions Mean for Your Roof
Sierra Madre’s streets are lined with mature deodar cedars and live oaks whose needles and leaves pack roof valleys tighter than in the flatter foothill towns down the hill. In Arcadia or Monrovia the tree debris lands on lawns. Up here it lands exactly where water concentrates, and it stays. On CertainTeed shingle roofs in Sierra Madre, valley cleaning and fascia rot repair are as routine as the shingle work itself. We’ve torn off CertainTeed fields where the field shingles had ten years of life left, but the valley shingles were so rotted from trapped cedar litter that they broke apart in our hands. That’s a Sierra Madre specific failure, not a CertainTeed defect. The shingles held up fine under a normal debris load. This canopy is not normal. If you live in the 91024 ZIP near the mature oaks, or up in 91025 closer to the mountain, count on twice-yearly valley clearing and an annual gutter check, more if you’ve got a deodar directly over the ridge.
CertainTeed Models & Products We Service in Sierra Madre
We install and repair the full CertainTeed line that fits Sierra Madre housing. Landmark architectural shingles are the workhorse on the ranch homes. Presidential Shake and Presidential TL show up on higher-end restorations where the homeowner wants the wood shake look without the fire hazard. For the low-slope and flat sections we use Flintlastic modified-bitumen membrane, often paired with CertainTeed underlayment and accessory flashings. We use genuine CertainTeed shingles and membrane so the system and any manufacturer warranty stay coherent, paired with quality underlayment and metal. For turnarounds in Sierra Madre, we keep common CertainTeed Landmark colors and accessory flashings stocked so a repair doesn’t wait on a distributor across the county.

AfterCertainTeed Service Pricing in Sierra Madre
What drives cost here more than the shingle itself is access and deck condition. A straight Landmark replacement on a ranch home with sound decking runs toward the lower end. A Craftsman with steep pitches, rot at tear-off, and valley damage runs more. Here’s how typical CertainTeed work breaks down in Sierra Madre:
- CertainTeed shingle repair (valley, tab, flashing): $350 – $850 depending on scope and roof access.
- Full Landmark roof replacement: $14,000 – $26,000 on the typical Sierra Madre bungalow or ranch, including tear-off, underlayment, flashing, and haul-away.
- Flintlastic flat-roof section repair or replacement: $2,800 – $7,500 depending on square footage and deck condition.
- Decking replacement at tear-off: $75 – $120 per sheet when rot is found under old conversions.
We give written line-item quotes before work starts, and the price doesn’t change mid-job unless you authorize something extra. Call (866) 321-6172 to schedule a free estimate in Sierra Madre.

FAQs – CertainTeed Roofing in Sierra Madre
No, we’re an independent CertainTeed roofing contractor, not a manufacturer-authorized or factory-certified dealer. That’s deliberate. Our loyalty runs to the homeowner and what the roof actually needs, not a manufacturer program. We install CertainTeed because Landmark, Presidential, and Flintlastic hold up well up here, and we’ll tell you when a repair beats a replacement.
Probably, and we’ll plan for it. Most of the original Craftsman bungalows in Sierra Madre had wood shake roofs, and decades of the shake trapping moisture against the decking softens the wood. When we tear off a later CertainTeed shingle layer, we assume some decking replacement. We check for soft spots before quoting, show you what we find at tear-off, and replace only the damaged sheets. Call (866) 321-6172 and we’ll inspect before you commit.
The shingles can, but the valleys can’t without maintenance. Landmark shingles have decent surface durability, but no shingle is designed to sit under a mat of decomposing needles. The failure happens where the litter traps water at the shingle edges and against the fascia. Twice-yearly valley clearing solves most of it. If you’ve neglected it for a few seasons, we can repair the valley and re-flash before you need a full roof.
Intense UV exposure on those planes breaks down the asphalt and granules faster. In Sierra Madre’s hot, dry climate, south and west exposures can look ten years older than the shaded north and east planes of the same roof. We see this uneven wear on nearly every CertainTeed home up here. If the south plane is shot but the rest is sound, we can replace just that plane, though color matching is easier if the roof is still under a few years old. Call (866) 321-6172 for a look.
Usually, yes. Flintlastic is a modified-bitumen membrane that handles the low-slope conditions better than shingles ever will. The catch is the transition where the flat section meets the shingle field, and that’s where we focus the flashing work. If the deck under the old tar-and-gravel is soft, we address that before the membrane goes down. Get a free estimate at (866) 321-6172 and we’ll confirm what your specific ranch roof needs.
