CertainTeed Roofing in Westwood, CA | Koreatown Roofing
We provide independent CertainTeed roofing service across Westwood, from emergency shingle repair to full re-roofs on mill-era houses. One thing separates our CertainTeed work here from anywhere else: nearly every roof we touch covers a home built or rebuilt after the 1911 Flanigan Mill fire, which means we’re stripping hand-nailed shingles off 1910s-1950s decks, not gluing caps onto fresh tract construction. That matters for how a CertainTeed roof performs, and it matters for how we repair it.
Koreatown Roofing is not a CertainTeed dealer. We’re an independent service provider, which means our only obligation is to the roof in front of us, not to a manufacturer’s quota. Call (866) 974-2271 for a free estimate on your CertainTeed repair or replacement, or for Northridge CertainTeed service.
Why Westwood Residents Choose Us for CertainTeed Service
Westwood homeowners don’t have time for a contractor who has to Google “CertainTeed Landmark” before quoting the job. Our crews know these shingle lines cold because we’ve torn into their failures across the Modoc Plateau for years. Landmark, Presidential Shake, Patriot, Xton, Flintlastic – we can tell you how each one behaves under deep wet snow and freeze-thaw, because we’ve seen it with our own eyes.
Manny Cordero grew up in Koreatown and learned the trade through the building trades program at Los Angeles Trade-Technical College, where instructors drilled material specs and installation sequencing into him before he ever set foot on a customer’s house. That training shows up in how we approach every CertainTeed job in Westwood: diagnose first, quote honestly, then do the work right. Tell me what your roof actually needs, and that’s what you’ll get – no upsell, no guesswork.
We’re roofing specialists, not generalists. One contractor, every stage. If your CertainTeed roof needs a small repair today and full replacement in five years, you won’t be shopping for a new company.

Common CertainTeed Roofing Problems We Solve in Westwood
- Freeze-thaw cracking and curling on Landmark and Presidential field shingles. Westwood’s high-desert winters mean snow sits on south-slope gables, melts during the day, and refreezes at night. That cycle works the asphalt mat until shingles crack along the freeze line. Then summer’s intense UV hits the same slope and dries out whatever’s left. We see this pattern constantly on 1940s and 1950s mill-era houses.
- Ice-dam backwater at eaves and valleys. Ponderosa pine needles from the surrounding national forest dump into roof valleys every fall. They dam the water, trap moisture against the shingle mat, and when winter arrives, ice dams form and push water backward under the CertainTeed course. The fix usually starts with valley cleaning and reflashing, not just caulk.
- Granule loss and exposed fiberglass on older Patriot and Xton installs. UV-and-snow abrasion is brutal on these lines, especially when the roof was laid over multiple tear-offs that were never properly stripped. Once the fiberglass mat shows through, that shingle is done. Targeted patching can buy a season; full replacement is the honest long-term call.
- Nail-popping and lifted field shingles over overdrawn decking. Westwood’s 1910s-1950s mill-era houses often have plank or skip-sheathing that’s been reused through multiple reroofs. When nails lose their grip in overdrawn wood, shingles lift. Wind and snowmelt get underneath, and the tear-off tears itself. We fix the deck before we touch the shingle.
- Three-layer tear-offs complicating new CertainTeed installs. Because Westwood was a one-company lumber town, most houses were built or rebuilt quickly after the 1911 and 1912-1913 fires. Quick construction led to layered reroofs over the decades. We routinely strip two or three layers of hand-nailed shingles before we can set fresh CertainTeed architectural shingles.
CertainTeed Service in Westwood: What Local Conditions Mean for Your Equipment
Here’s the thing nobody outside Westwood understands: this town’s nickname, “the Westwood way,” comes from being a one-company lumber town. Nearly every roof here covers a house built or rebuilt after the 1911 Flanigan Mill fire and the 1912-1913 fire. No neighboring Lassen County town shares that timber-company origin or a housing stock tied to one mill. That means when we’re servicing a CertainTeed roof in Westwood, we’re almost never working on a clean plywood deck from 2005. We’re working on 1910s-1950s plank or skip-sheathing that’s been overdrawn by decades of snow load and layered tear-offs. A nail that holds fine in Susanville won’t hold the same in Westwood, because the deck underneath is a different animal entirely. That’s why our CertainTeed work here always starts with a deck assessment before we quote the shingle work. If the deck is soft, no Landmark or Presidential shingle on earth will save the roof.
On a 1940s mill-worker house in the Westwood flats, our crew found three layers of old hand-nailed shingles over overdrawn plank decking with a Landmark field curling at the eaves and a needle-choked valley backing water in. We stripped to the sheathing, replaced soft deck boards, reflashed the valley with new underlayment, and set fresh CertainTeed architectural shingles with proper eave ventilation so snow load vents clear next winter. That’s the kind of job you only get right if you’ve done it before.
CertainTeed Models & Products We Service in Westwood
We service the full CertainTeed residential line, including CertainTeed in North Hills: Landmark architectural shingles, Presidential Shake and Presidential TL luxury shingles, Xton and Patriot asphalt shingles, and Flintlastic for low-slope applications. When the existing line is still in production, we match CertainTeed OEM shingles and accessories so repairs blend and stay warrantable. When a line has been discontinued, we use quality aftermarket flashing and underlayment and tell you straight whether a targeted repair buys real time or whether full replacement is smarter.
For Westwood turnaround, we keep common CertainTeed Landmark colors on hand and can source Presidential and Flintlastic quickly through our local supply partners. That means less waiting when your roof needs attention before the next snow.

AfterCertainTeed Service Pricing in Westwood
CertainTeed shingle repair in Westwood typically runs $350-$850 for a targeted repair on a Landmark or Patriot roof, depending on how many courses are damaged and whether decking needs attention. Valley repair with reflashing and new underlayment generally lands $900-$1,600. Full CertainTeed re-roofs on Westwood’s mill-era houses run $11,000-$20,000+ depending on tear-off layers, deck replacement scope, and the CertainTeed line you choose.
What drives cost here more than anywhere: layered tear-offs. Westwood houses carry two or three layers more often than not, and every layer adds labor and disposal. A free estimate from us includes a deck assessment, a line-by-line scope of work, and an honest recommendation on repair versus replace. Call (866) 974-2271 to schedule yours.

FAQs – CertainTeed Roofing in Westwood
Yes, if the damage is localized and the deck underneath is sound. We match CertainTeed OEM shingles when the line is still in production so the repair blends. But on Westwood’s older mill-era decks, we’ll check the sheathing before promising a patch – soft decking under a cracked shingle means the repair won’t hold through one freeze-thaw cycle. Call (866) 974-2271 for an honest assessment.
In Westwood, it’s almost always ponderosa needle accumulation in valleys and behind chimneys. Needles trap moisture against the shingle mat, and when deep wet snow sits on top and refreezes, ice dams form and back water under the CertainTeed course. The fix is needle-clearing and reflashing, plus checking that your eave ventilation is clear so snowmelt drains properly. Call (866) 974-2271 – we’ll diagnose it on site.
We keep common Landmark colors stocked for Westwood jobs and can source the rest quickly through our local suppliers. If your exact color has been discontinued, we’ll tell you up front and show you the closest available match before we lift a hammer.
Usually yes, once the deck is addressed. The 1920s mill-era framing in Westwood is often sturdier than people expect – old-growth timber that’s held snow load for a century. The weak link is the overdrawn plank or skip-sheathing. We strip to the sheathing, replace what’s soft, and then set fresh CertainTeed architectural shingles with proper ventilation. The house can handle it; the deck just needs to be right first.
Snow load management starts with ventilation and insulation, not just shingle choice, whether it’s here in Westwood or with our CertainTeed service in Shadow Hills. Westwood’s deep wet snow needs a roof that vents heat from the attic so snow melts evenly and drains, rather than refreezing into ice dams. We assess your eave and ridge ventilation as part of every CertainTeed job here, because a well-vented Landmark roof outperforms a poorly vented Presidential every single winter. Call (866) 974-2271 for a free estimate that covers ventilation, not just shingles.
