CertainTeed Roofing in Altadena, CA | Marquis Roof Repair
CertainTeed roofing service in Altadena means matching the right shingle or membrane to a foothill climate that punishes roofs differently than Pasadena CertainTeed repair just below. We are an independent contractor, not a CertainTeed-authorized dealer, and we repair and install their Landmark, XT, Presidential, and Flintlastic lines across both Altadena ZIP codes, 91001 and 91003. What sets our CertainTeed work apart here is knowing how oak litter, Santa Ana winds, and unpermitted additions change what a roof actually needs. Call (866) 705-2978 for a free estimate from Marquis Roof Repair.
Why Altadena Residents Choose Us for CertainTeed Service
Ron Thibodeau grew up in Magnolia Park in Burbank, where his uncle’s contracting operation taught him that shortcuts show up eventually. He studied building construction technology at Los Angeles Valley College, then spent more than two decades roofing across the San Fernando Valley before putting Marquis Roof Repair in Burbank. That background matters when an Altadena homeowner calls about CertainTeed shingles that are failing on one pitch but not another. We have CertainTeed sales & service experience across the foothills, and we’ve seen how their mat and granule formulations behave under San Gabriel UV. As an independent contractor we’re not authorized, sponsored, or warranted by CertainTeed. We simply know the product line well and repair it honestly. When you call, you get a roofer who investigates before recommending, not a sales script.

Common CertainTeed Roofing Problems We Solve in Altadena
- Early granule shed on south-facing Landmark fields. Altadena sits at 1,000 to 1,400 feet, and those south pitches bake harder than anything Pasadena gets. Granules shed early, the mat dries, and cracks open along the exposure line.
- Valley rot from oak and deodar litter. Leaf litter packs the valleys and behind chimneys, holds tannin-stained moisture, and rots the CertainTeed underlayment first, then the original board sheathing beneath it. We rebuild valleys and replace the decking, not just the shingles.
- XT 25 three-tab lifting on 1960s porch roofs. After Santa Ana wind events, these low-slope porch roofs lift at the rake and ridge, especially where old fasteners have loosened over decades. We re-fasten, re-terminate, and replace torn shingles.
- Flintlastic SA seam failures on unpermitted patio covers. Where old additions tied into the original deck without proper terminations, Flintlastic membranes fail at seams and perimeter flashing. We correct the tie-in and re-lay the membrane.
- Wind-lifted ridge caps on baked south pitches. The failing pieces are almost always on homes where the south-facing pitch has baked for decades and no one has cleaned the oak litter from the valleys. We see this repeatedly after each Santa Ana event west of Lake Avenue.
CertainTeed Service in Altadena: What Local Conditions Mean for Your Roof
Here’s the thing about Altadena roofing that doesn’t show up on a generic brand page. Because Altadena is unincorporated county territory, a CertainTeed re-roof on a 1950s ranch with an unpermitted addition often requires us to establish which code and permit path actually governs the 60-year-old roof before material goes down. That step doesn’t come up the same way just over the line in Pasadena, where city inspectors follow one set of rules. In Altadena we’ve torn into roofs where the original board sheathing was never replaced, an addition was tied in without proper flashing, and the question of what code applies to the re-roof has to be answered before we quote the job honestly. Our Altadena service area coverage means we know these unpermitted-addition situations and handle the paperwork path correctly. When you need CertainTeed shingles matched after a deck replacement, the code question has to be settled first, and we settle it.
CertainTeed Models & Products We Service in Altadena
We install, repair, and replace the CertainTeed lines most common on Altadena’s 1920s-1960s ranch and bungalow housing stock: Landmark architectural shingles including Landmark Pro, XT 25 and XT 30 three-tabs, Presidential and Presidential Shake luxury shingles, and Flintlastic SA self-adhered membranes for low-slope porch and patio-cover applications. Our repair approach uses OEM-profile matching by shingle profile, color, and exposure so a repair blends into the existing field instead of standing out like a patch. We stock common Landmark colors locally for faster Altadena turnaround and keep Flintlastic membrane and quality flashing on hand for low-slope fixes. For anything not in the truck, our parts network gets it to Altadena quickly.

AfterCertainTeed Service Pricing in Altadena
CertainTeed shingle replacement in Altadena typically runs $12 to $22 per square foot depending on the shingle line, decking condition, and pitch. Valley repair with decking replacement starts around $800 to $1,500 for a typical valley run, and Flintlastic low-slope membrane repair runs $600 to $1,200 per section depending on seam damage and perimeter flashing work. The biggest cost driver here is decking: at least half of Altadena re-roof jobs involve rebuilding or reframing skipped decking rather than just laying new material. A free estimate includes a roof inspection, a written line-item quote, and an honest repair-versus-replace recommendation. Call (866) 705-2978 to schedule yours, and we’ll tell you straight what your roof actually needs.

FAQs – CertainTeed Roofing in Altadena
No, but it changes the maintenance picture. CertainTeed’s warranty addresses manufacturing defects, not leaf litter, and oak litter packed into valleys and behind chimneys holds moisture that rots underlayment and decking regardless of shingle quality. We rebuild valleys, clean debris, and recommend a maintenance schedule that keeps the warranty intact. Call (866) 705-2978 for a free inspection if your roof has oak overhang.
Sometimes. If the board sheathing is solid and dry, re-covering is acceptable. But in Altadena, where decades of oak litter and South Pasadena CertainTeed repair conditions like south-pitch UV have baked and softened original boards, we often find sections that must be stripped and replaced before any CertainTeed shingle goes down. We inspect the decking section by section and tell you which route is honest for your roof.
Altitude. Altadena sits at 1,000 to 1,400 feet at the foot of the San Gabriels, taking hotter summer days and more intense UV than Pasadena below, plus periodic dry Santa Ana winds and cold-air-pooling nights. Those conditions swing roof surface temperatures hard, shrinking and cracking asphalt shingles and stressing flashing and fasteners faster than in the city below. Your neighbor’s roof isn’t the same roof climate.
No. Marquis Roof Repair is an independent roofing contractor. We install and repair CertainTeed products regularly, but we are not authorized, sponsored, or warranted by CertainTeed. That independence means our recommendations are driven by your roof, your climate, and your budget, not by which brand we’re obligated to push.
It depends on the seam damage and what’s under the membrane. If the seams are failing but the membrane field is intact and the decking below is dry, a seam repair with proper terminations usually holds for years at $600 to $1,200. If water has been getting in long enough to soften the decking, replacement is the only honest answer. Call (866) 705-2978 and we’ll inspect the membrane and tell you which route your porch actually needs.
