CertainTeed Roofing in Encino, CA | Marquis Roof Repair
We provide independent CertainTeed roof inspection, repair, and replacement across Encino, including the 91316, 91416, and 91436 ZIP codes. The one thing that makes our CertainTeed work here different? We understand how these roofs actually fail under Encino’s specific conditions: brutal San Fernando Valley sun on south and west slopes, then concentrated winter rains that find every weak flashing and cracked underlayment from decades of piecemeal additions. Call (866) 705-2978 for a free estimate on anything from a valley leak to a full Landmark Series reroof.
Why Encino Residents Choose Us for CertainTeed Service
CertainTeed makes a broad product line, and we’ve spent years working with nearly all of it across the Valley: Landmark Series asphalt shingles, Presidential Shake TL, Symphony Slate, Cedar Impressions, and their low-slope membranes like Flintlastic. We know which products hold up on Encino’s hottest exposures and which ones need specific underlayment and flashing details to survive the rainy season. Ron Thibodeau, our owner, studied building construction technology at Los Angeles Valley College and spent more than two decades doing roofing work across the San Fernando Valley before founding Marquis. That means when we diagnose a CertainTeed issue on an Encino roof, we’re drawing on hands-on experience with this exact housing stock and climate. We’re an independent CertainTeed service provider – not manufacturer-affiliated or authorized – which means our recommendations are driven by what your roof actually needs, not by a brand quota. From first inspection to final shingle, the job gets done to the Marquis standard.

Common CertainTeed Roofing Problems We Solve in Encino
These are the failure patterns we see most often on CertainTeed roofs in Encino, and they rarely show up the same way in other parts of Los Angeles:
- Accelerated granule loss on south and west slopes. CertainTeed’s Landmark shingles can begin showing surface cracking and granule shedding after 12-15 years on Encino’s hottest exposures, well before their rated lifespan. We see it most on 91436 hillside properties where roofs take full sun with no tree cover.
- Brittle underlayment under tile roofs. CertainTeed underlayments can become heat-baked and brittle at eaves and valleys after years of thermal cycling under Encino’s summer roof temperatures. Once it tears, the first heavy storm of the rainy season puts water straight onto your decking.
- Flintlastic seam failures on flat-roof additions. Many Encino ranch homes have flat or low-slope additions over garages, family rooms, or later expansions. The CertainTeed Flintlastic membrane at those seam and flashing transitions is a common leak point, especially where the flat section ties into the original pitched roof.
- Wind-driven rain behind drip edge and starter strips. Encino gets concentrated, wind-driven storms rather than steady drizzle. Improperly sealed CertainTeed drip edge and starter strips let water push back behind the fascia, and the resulting rot is invisible until interior paint starts bubbling.
- Valley flashing corrosion on mix-and-match remodels. When a 1990s or 2000s addition was tied into an original 1950s roof, the valley where they meet is often the first thing to go. We routinely find corroded metal and cracked underlayment at those transitions.
CertainTeed Service in Encino: What Local Conditions Mean for Your Equipment
Encino’s housing stock creates a specific challenge for CertainTeed owners that you won’t find in Sherman Oaks or Studio City to the same degree. Most of the original homes here are 1940s-1960s California ranch and contemporary builds, and many were expanded decades later – a second story here, a family room bump-out there, a garage conversion somewhere else. That means your CertainTeed roof is rarely a single, uniform system. It’s a patchwork. We frequently find CertainTeed shingles on a newer pitched addition tied into the original low-slope section with a failing metal transition, or original 1950s framing under newer tile with underlayment that’s past its useful life. In the 91436 hillside properties especially, multi-plane roofs with numerous valleys and penetrations put enormous stress on flashing details during heavy rain. A “simple” leak repair on an Encino ranch home often turns into a transition rebuild, because the leak isn’t really at the shingle – it’s at the seam where two eras of construction meet.
Last spring, a homeowner on Amestoy Avenue in Encino called us about a ceiling stain that appeared after a storm. We traced it to a failed CertainTeed valley flashing where a 1990s addition met the original 1950s flat roof. The older underlayment had cracked, the metal valley had corroded, and water had been working its way through for weeks before the stain showed up. We replaced the valley with a new CertainTeed Flintlastic membrane and matching shingles, then rebuilt the transition flashing. No more leaks through the next rain. That’s the kind of repair you only get right if you’ve seen how Encino’s remodels actually got built.
CertainTeed Models & Products We Service in Encino
We service and install the full range of CertainTeed residential roofing products found on Encino homes. That includes the Landmark Series asphalt shingle line in all its variants, Presidential Shake TL, Symphony Slate, Cedar Impressions, and Flintlastic low-slope membranes. When a repair requires components, we use genuine CertainTeed accessories and underlayments whenever they’re available – they’re engineered to work as a system. But we’ll also recommend high-quality aftermarket components when a specific Encino condition calls for it, like a more UV-resistant underlayment for a west-facing tile roof where the original CertainTeed underlayment has failed once already. We stock common CertainTeed shingle colors and accessory parts locally for faster turnaround on Encino repairs, and we can match existing shingles on most Landmark color blends without needing a full reroof.

AfterCertainTeed Service Pricing in Encino
What you’ll pay depends on what your roof actually needs. A targeted flashing or valley repair on a CertainTeed roof in Encino typically runs between $350 and $900, depending on access and the extent of the transition work. Tile underlayment replacement, especially on a hillside property with steep access, generally lands between $4.50 and $8.00 per square foot of roof area. A full CertainTeed reroof on a typical Encino ranch home usually runs $14,000 to $32,000, with multi-plane hillside roofs in 91436 coming in higher. Your free estimate from Marquis includes a thorough inspection, specific measurements, and a written line-item quote – no vague allowances. We investigate before we recommend, so you won’t get pushed toward replacement when a precise repair will hold. Call (866) 705-2978 for exact pricing on your roof.

FAQs – CertainTeed Roofing in Encino
Look at the slopes that face south and west. On Encino rooftops, those are the surfaces that take the Valley’s most intense UV exposure, and CertainTeed Landmark shingles there can show granule loss, surface cracking, and curling well before shingles on the shaded north side. Run your hand over the surface – if granules come off like sand, the UV has already broken down the shingle’s protective layer. That’s not a cosmetic issue; it’s the roof losing its weather barrier. Call (866) 705-2978 and we’ll tell you honestly whether it’s time to repair or replace.
Seam and flashing failures are the most common Flintlastic problem we see in Encino, and it comes down to thermal cycling. The Valley’s summer heat expands the membrane, winter cools it, and over years the seams and transition points – where the flat section meets the pitched original roof – can separate or split. When the first heavy storm hits, water finds those openings. The fix is almost always a transition rebuild: new membrane, new flashing, and proper sealing at the tie-in. We do this repair regularly on Encino ranch homes.
We use genuine CertainTeed underlayments when they’re the right product for the specific roof, but we don’t default to them. On a west-facing tile roof in Encino, where underlayment gets baked repeatedly every summer, we may recommend a more UV-resistant aftermarket underlayment that will outlast what was originally installed. It’s not about brand loyalty; it’s about what holds up under this specific climate. Call (866) 705-2978 and we’ll assess your roof and explain the options.
In most cases, yes. We keep common CertainTeed Landmark color blends in stock for Encino service calls, and we can match most existing shingles well enough that the repair doesn’t stand out. For discontinued colors or older lines, we’ll source the closest available match and tell you honestly if a patch will be visible. A visible patch is still better than a leak, but we’ll always give you the option.
The answer starts with understanding why that transition is leaking. On Encino’s expanded ranch homes, the seam between the original low-slope section and a later pitched addition is often the weakest point on the entire roof. Properly handling it means rebuilding the transition flashing, replacing the underlayment at the tie-in, and ensuring the membrane laps correctly for water flow. There’s no shortcut. Call (866) 705-2978 for a free estimate and we’ll walk you through what your specific transition needs.
