CertainTeed Roofing in Van Nuys, CA | Koreatown Roofing
We provide independent CertainTeed roofing service across Van Nuys, from shingle replacement to flat roof patches. The one thing that makes our CertainTeed work different here is simple: we know how these products age under San Fernando Valley heat, not just how they look in a catalog. Call (866) 974-2271 for a free estimate from a roofing-only crew that works with seven major manufacturers and lets you pick what fits your roof.
Koreatown Roofing is an independent CertainTeed service provider. We are not manufacturer-affiliated, authorized, or warranty-endorsed by CertainTeed. We specify and install Landmark, Xton, Presidential, and Flintlastic systems because they hold up in Van Nuys when detailed correctly. If you need a specialist who can explain exactly what your CertainTeed roof needs, we’re the crew to call. For more on our broader material lineup, see our CertainTeed sales & service page.
Why Van Nuys Residents Choose Us for CertainTeed Service
We’re roofing specialists, not generalists. Every job we take is a roof, and a good share of those are CertainTeed systems that other contractors misdiagnose or band-aid. Manny Cordero, our owner, learned the trade through the building trades program at Los Angeles Trade-Technical College, where instructors drilled material specs and installation sequencing before he ever touched a customer’s house. That training shows when we walk a Van Nuys roof and point out exactly why your Landmark shingles are shedding granules at the rake while the field still looks okay — the same expertise we bring to our Roof Repair – Van Nuys customers.
We work with seven manufacturers, CertainTeed among them, and offer Sherman Oaks CertainTeed service as well. That means our product recommendations are driven by fit for your Van Nuys roof, not by what one supplier has in stock. One contractor covers every stage: inspection, repair, and replacement. You don’t shop for a new company when a patch becomes a tear-off.

Common CertainTeed Roofing Problems We Solve in Van Nuys
- Brittle Landmark and Xton shingles. Valley summers routinely exceed 100°F, and that heat pulls volatile oils out of asphalt shingles. Within a decade, Landmark and Xton fields in Van Nuys turn brittle, shed granules, and crack at the rake and ridge long before the rated life. We see it on tract homes all over 91401 and 91405.
- Sun-baked pipe boots and vent collars. Reflective Landmark IR shingles help with attic heat, but they still fail at penetrations first. Van Nuys sun cooks pipe boots and vent collars until they crack open, and the first winter rain goes straight to the deck. We replace boots with aftermarket parts that outperform the OEM under Valley UV.
- Flintlastic wrinkles and blisters on flat sections. On the low-slope rear additions common on post-WWII Van Nuys homes, Flintlastic SA and GTA membranes wrinkle, blister, and pull at the seams when installed over an unvented deck in 100°F-plus attic heat. We strip, re-fasten, and detail these flat sections properly.
- Flashing and valley failures over uneven decking. When metal flashing is fastened over old, uneven decking, the shingle above it telegraphs every hump. The CertainTeed field cracks and lifts in the first hot season after install. We see this on mid-century apartment buildings and older tract homes throughout Van Nuys.
- Hidden layers on never-stripped flat roofs. In the older blocks of 91401 and 91405, many original flat roofs carry multiple un-stripped layers of tar paper and gravel. A CertainTeed low-slope tear-off here can reveal unexpected weight, rotted decking, and hidden leaks that nobody saw coming.
CertainTeed Service in Van Nuys: What Local Conditions Mean for Your Equipment
Here’s what makes Van Nuys different from, say, Santa Monica or West LA: the Valley’s summer heat is relentless, and roofs here age on an accelerated schedule. Van Nuys sits in the San Fernando Valley, where temperatures routinely exceed 100°F and intense UV exposure degrades asphalt shingles and flat-roof membranes far faster than in coastal Los Angeles. That’s why local roofers who know CertainTeed specify heat- and UV-resistant materials and often recommend reflective cool-roof coatings to meet Title 24 energy rules. On a 1950s tract house near Van Nuys Boulevard in 91401, our crew tore off three built-up layers plus gravel to find the original deck had been patched around a leaking vent stack. We replaced the rotted sheathing, laid CertainTeed Flintlastic SA over the flat rear section, and ran Landmark Pro shingles up the front slope with new pipe boots and kick-out flashing. The homeowner’s winter leak stopped, and the reflective Landmark IR field cut attic heat noticeably that first August. That’s the kind of local detail a generic roofing crew won’t catch.

AfterCertainTeed Service Pricing in Van Nuys
What you’ll pay depends on the CertainTeed system on your roof and what’s actually failing. Here’s what Van Nuys homeowners typically see:
- Shingle replacement (spot repair): $350 – $750, depending on the number of shingles and whether decking is damaged underneath.
- Pipe boot or vent collar replacement: $180 – $400 per penetration, including removal of the old sun-baked boot and new flashing.
- Flat roof patch (Flintlastic SA or GTA): $450 – $1,200, depending on the size of the failed section and how many layers need to come off first.
- Full CertainTeed tear-off and reroof (Landmark shingle field): $9,500 – $18,000 for a typical Van Nuys tract home, with flat sections quoted separately.
What drives the cost: the number of existing layers, deck condition, accessibility, and whether pre-1980s material needs asbestos testing before disposal. Our free estimate includes a written, line-by-line scope, so there are no surprises when the crew shows up. Call (866) 974-2271 to schedule yours.

FAQs – CertainTeed Roofing in Van Nuys
Yes. Landmark IR shingles use reflective granules that reduce heat absorption into the attic, which matters when Van Nuys temperatures top 100°F for weeks at a time. They’re not a substitute for proper ventilation, but they take a measurable edge off attic heat and can help with Title 24 compliance. Call (866) 974-2271 for a quote on your specific roof.
Usually not. Multiple layers of aging tar paper and gravel hide rot, uneven decking, and hidden leaks. We strip to the deck, check for asbestos on pre-1980s material, repair what’s underneath, and then install Flintlastic SA or GTA over a clean, sound surface. Covering it up just guarantees a bigger problem later. Call (866) 974-2271 and we’ll inspect what’s actually under those layers.
Under Van Nuys heat, a properly installed Landmark field typically lasts 15 to 22 years, not the 25 to 30 you see in temperate climates. The sun here pulls oils out of the asphalt and makes shingles brittle. Details like flashing, boots, and underlayment matter as much as the shingle itself. If your roof is at the 12-year mark and shedding granules, it’s worth an inspection before winter rains. Estimates are free.
Sometimes, but not always. A patched valley, flashing, or boot on a 12-year-old brittle CertainTeed shingle is a bridge, not a fix. If the field is granule-starved and cracked, patching buys you a season at most. We’ll tell you straight: when replacement is the cheaper path over five years, that’s what we recommend. Tell us what your roof actually needs, and that’s what you’ll get – no upsell, no guesswork. Call (866) 974-2271 for an honest assessment.
Yes. We service the full CertainTeed residential lineup, including Presidential Shake, Presidential Solaris, Xton, and Northgate. These heavier architectural lines have their own failure patterns under Valley heat, and we know what to look for. If you own a CertainTeed roof in Van Nuys, we can work on it, and we also provide CertainTeed repair in Encino.
