CertainTeed Roofing in Glendale, CA | Marquis Roof Repair
We provide independent CertainTeed roofing service across Glendale, from tile underlayment replacement in the Verdugo foothills to flat roof patches on south-side apartment buildings. What makes our CertainTeed work here different is simple: we know how these products actually behave under Glendale’s specific conditions, which is why we lift failed underlayment instead of patching over it. If you’re looking at a leak, missing granules, or a suspect flat roof, call us at (866) 705-2978 for a straight diagnosis.
Why Glendale Residents Choose Us for CertainTeed Service
Most roofing crews in Glendale either know tile or they know flat work. We’ve spent years doing both, often in the same week. That matters when your CertainTeed Landmark shingles are blistering on a 1940s Spanish Colonial on a Tuesday and we’re seam-splitting a modified-bitumen cap sheet on a south Glendale apartment roof by Thursday.
Ron Thibodeau runs our operation, and he grew up around construction in CertainTeed repair in Burbank, learning early that shortcuts always show up eventually. That’s the mindset we bring to every CertainTeed roof in Glendale: investigate before we recommend. We use genuine CertainTeed accessories like ridge vents, starter strips, and underlayments when they’re available and appropriate. When a compatible aftermarket component is the better call for a repair, we’ll tell you that too, with full transparency about what it means for your warranty.
We’re an independent CertainTeed service provider, not authorized or partnered with CertainTeed. That independence means our recommendations are driven by your roof and your budget, not by a manufacturer’s quota. Seven manufacturer lines, one point of contact. From first inspection to final shingle, the job is built to the Marquis standard.

Common CertainTeed Roofing Problems We Solve in Glendale
- Granule loss and nail-head pops on Landmark shingles in north Glendale. The 1920s-1940s Spanish Colonials in 91202 and 91208 often have inadequate attic ventilation. Summer heat that bakes those attics cooks the shingles from below, and by year 12 to 15 you’ll see granules in the gutters and exposed nail heads. We don’t just replace the shingles; we address the ventilation so the new CertainTeed roof doesn’t repeat the same failure.
- Tile underlayment failure on original barrel tile roofs. Glendale’s 100°F-plus summers dry out CertainTeed underlayment long before the tile itself fails. The tile looks fine from the street. Then a winter storm hits and water finds every crack in the felt. When we see this, we lift the original tile, replace the underlayment properly with a system like CertainTeed DiamondDeck, and reset the tile. Patching over failed underlayment is a waste of your money.
- Blistering and seam splits on flat modified-bitumen roofs in south Glendale. The dense 1950s-1970s apartment buildings in 91201 and 91204 have low-slope roofs that absorb valley heat all day. CertainTeed cap sheets can blister and split at the seams when the deck isn’t properly vented. We see this failure mode constantly on south-side apartment buildings.
- Flashing failures at skylight curbs and wall intersections. On hillside homes above Glenoaks Boulevard, wind-driven rain and Santa Ana uplift stress every flashing detail. When CertainTeed flashing accessories were originally paired with incompatible sealants, or when the old galvanized flashing never got replaced during a previous re-roof, those intersections leak early. We repair them with the right materials for the detail, not whatever is on the truck.
- Santa Ana wind damage on ridge caps and tile edges. The Verdugo Mountains and Chevy Chase canyon edges expose roofs to wind uplift that pulls ridge caps loose and lifts tile edges. After a Santa Ana event, we regularly find broken or missing ridge caps on CertainTeed tile systems where the original mortar bedding has dried and cracked over decades of heat cycling.
CertainTeed Service in Glendale: What Local Conditions Mean for Your Equipment
Here’s something you won’t find on a generic CertainTeed service page: La Cañada Flintridge CertainTeed service aside, Glendale’s Armenian-American homeowner base negotiates roofing differently than most neighboring cities. A large share of the work we do here comes through multigenerational family referrals and church networks, not web leads. That means a roofer’s reputation for honest diagnosis and cash-competitive bidding carries more weight than a stack of online reviews. This shapes how we work. When a homeowner on a hillside street above Glenoaks calls us about a leak, they’ve usually already asked three family members who to call. We arrive knowing that our work gets discussed at Sunday dinner. That’s a higher bar than any review platform, and we build our estimates with that in mind: fixed line-item pricing, no change orders, and a written explanation of exactly what we found and what we recommend. A roof done right the first time is the only version worth doing.
CertainTeed Models & Products We Service in Glendale
We service the full range of CertainTeed roofing systems that show up on Glendale homes and apartment buildings. That includes Landmark shingles, Landmark Pro, and Landmark Solaris, Presidential Shake TL and Solaris, Symphony slate-look shingles, and CertainTeed clay and concrete tile systems with their underlayment lines like DiamondDeck and RoofRunner. We also work on CertainTeed low-slope and flat roofing products used on south Glendale apartment stock. For parts, we stock the CertainTeed accessories most commonly needed for Glendale repairs, and when a repair calls for something we don’t have on the truck, we source it fast so your roof isn’t left open longer than necessary. On tile roofs, our approach is to lift and replace failed underlayment rather than patch it, because the underlayment is the waterproofing layer in a true CertainTeed system.

AfterCertainTeed Service Pricing in Glendale
CertainTeed roofing repair in Glendale typically falls into a few common ranges. A targeted flashing repair runs $350 to $900 depending on access and the specific detail. Tile underlayment replacement on a section of barrel tile roof starts around $1,800 to $4,500 for a typical repair area, while a full flat roof patch on a south Glendale apartment runs $2,500 to $6,500 depending on square footage and deck condition. A full CertainTeed Landmark shingle re-roof on a north Glendale Spanish Colonial generally lands between $14,000 and $28,000, with decking repairs and ventilation upgrades driving the final number. What changes the price here: roof pitch and access on hillside streets, the condition of the original skip sheathing, and whether we’re lifting tile or working over an existing deck. Every estimate includes a written line-item breakdown. Call (866) 705-2978 to schedule yours, it’s free and there’s no obligation.

FAQs – CertainTeed Roofing in Glendale
Yes. We lift the original tile, remove the failed underlayment, inspect the decking and skip sheathing, and install a new CertainTeed underlayment like DiamondDeck before resetting the tile. This is standard work for us in north Glendale’s 91202 and 91208 neighborhoods. If your tile roof is leaking but the tile looks fine, the underlayment is almost certainly the culprit. Call (866) 705-2978 for an inspection.
Yes, and we see this in Glendale more than in neighboring cities. The granule loss usually points to an attic ventilation problem, not defective shingles. The 1920s-1940s Spanish Colonials in north Glendale often don’t have enough airflow, so the shingles overheat from below. We’ll diagnose the real cause before recommending anything. A repair may be enough, or we may recommend adding ventilation to protect the remaining shingles. Estimates are free.
It depends on the deck condition and the roof’s exposure to sun. CertainTeed’s modified-bitumen systems work well on the dense 1950s-1970s apartment buildings in 91201 and 91204 when the deck is properly vented. If your flat roof is blistering or the seams are splitting, the issue may be a venting problem rather than a product problem. We’ll inspect and tell you what’s actually going on before we quote.
Yes. Hillside homes above Glenoaks Boulevard in Glendale take wind-driven rain and Santa Ana uplift that stress flashing details at skylight curbs, chimneys, and wall intersections. We repair and replace flashing using the correct materials for each detail, with full transparency about what’s compatible with your CertainTeed system. Call (866) 705-2978 and we’ll schedule a look.
It can be, but the installation details matter more than the shingle itself. Glendale’s summer heat and Santa Ana winds stress any steep-slope roof, so proper ventilation and secure ridge caps are essential regardless of which CertainTeed line you choose. We’ll walk you through the trade-offs between Presidential Shake TL, Presidential Shake Solaris, and other lines based on your home’s exposure and your budget. Call for a free consultation.
