CertainTeed Roofing in Alhambra, CA | Marquis Roof Repair
We provide Roof Repair in Alhambra for CertainTeed systems across the city, from 91801 down through 91896. The thing that makes our CertainTeed work here different is simple: we know how these roofs fail on pre-war bungalows and Spanish Colonial Revivals, not just how they look new on a spec sheet. Alhambra’s housing stock runs 1910s through 1950s, and CertainTeed shingles age differently under our San Gabriel Valley sun than they do anywhere else in LA County. If your CertainTeed roof is showing its age, call (866) 705-2978 for a diagnostic inspection and a straight answer.
We’re Marquis Roof Repair, and we’ve spent years tearing off and repairing CertainTeed roofs across Alhambra’s older neighborhoods. We’re not authorized by CertainTeed, and we won’t pretend otherwise. What we are is practical: we carry genuine CertainTeed materials for warranty-compliant work, and we know when a quality aftermarket flashing will outperform the original. If you need CertainTeed sales & service from a crew that actually understands Alhambra’s rooflines, you’re in the right place.
Why Alhambra Residents Choose Us for CertainTeed Service
Most roofing companies offering CertainTeed service in San Gabriel either chase new construction or treat the brand as just another shingle line. We don’t have that luxury in Alhambra. The homes here demand a roofer who can diagnose a failing CertainTeed Landmark roof on a 1928 craftsman bungalow and know whether that granule loss is normal aging or the start of something worse. That’s our wheelhouse.
Ron Thibodeau, our owner, learned roofing the hard way, starting on job sites in the San Fernando Valley and spending more than two decades figuring out why roofs fail. He studied building construction technology at Los Angeles Valley College, but the real education came from tearing off failed roofs and seeing exactly where shortcuts show up. Homeowners across Alhambra service area know Ron as the roofer who finds the actual source of a leak, not just the stained ceiling below it.
We stock genuine CertainTeed shingles, underlayments, and accessories so repairs move fast. We also keep quality aftermarket flashings and vents on hand for when they’ll hold up better than OEM. You get one crew that knows the product, knows the neighborhood, and gives you an honest read on repair versus replacement. No brand agenda. No upsell theater.

Common CertainTeed Roofing Problems We Solve in Alhambra
- Landmark granule loss and edge curling on low-pitch hip roofs. Alhambra’s Spanish Colonial Revivals almost all carry low-pitch hip roofs, which happen to be where CertainTeed Landmark shingles show UV stress first. After 12 – 15 years of our summer heat cycling, you’ll see granules in the gutters and shingle edges lifting. We can replace individual shingles if the field is solid, or do a targeted section replacement when it’s not.
- XT 25/30 three-tab shingles cracking over swollen decking. Alhambra bungalows frequently carry three or four layers of old roofing, and the bottom layers are often original CertainTeed three-tab from decades ago. Winter rain finds its way underneath, the decking swells, and the shingles on top crack and blister. We tear off, assess the decking, and tell you honestly whether you need new plywood or just new shingles.
- Flintlastic underlayment failing at valley transitions. This is the Alhambra problem. Our mature ficus and camphor trees drop leaves that pile up in roof valleys every fall and winter. Water dams behind the debris, sits against the underlayment, and eventually the Flintlastic wrinkles or tears. The leak shows up inside months later. We repair the valley properly and usually recommend leaf management so it doesn’t return next season.
- Presidential Shake wind uplift at hip ridges during Santa Ana events. Presidential Shake is a thick, heavy shingle, but the original CertainTeed ridge cap adhesive doesn’t last forever. When Santa Ana winds hit Alhambra in the fall, we see ridge caps lifted or missing on exposed rooflines. It’s usually a contained repair, not a full re-roof, if you catch it before water gets underneath.
- Multiple-layer tear-offs with hidden decking rot. Alhambra’s older homes often have roofs on their third or fourth layer. That’s technically against code, and it hides problems. We tear off down to the decking on replacements, and we frequently find rot at the eaves and valleys that other contractors would have shingled right over. You can’t warranty a roof on rotted plywood, so we fix it first.
CertainTeed Service in Alhambra: What Local Conditions Mean for Your Roof
Alhambra’s numbered streets, especially the blocks between Main Street and Mission Road, are lined with mature ficus and camphor trees that have been growing for sixty or seventy years. Those trees are beautiful, but they’re also the single biggest environmental factor in how CertainTeed roofs fail here. Every fall and winter, those leaves drop into valleys and gutters. They’re not lightweight leaves either. Camphor leaves are waxy and slow to break down, and ficus leaves form dense mats that trap water. On a CertainTeed roof with original Flintlastic underlayment, that trapped water sits against the valley metal and underlayment seams for weeks. The result is valley rot that we see over and over on CertainTeed roofs in Alhambra, and almost never see a few miles away in Monterey Park CertainTeed service areas with fewer mature trees. If your roof has original underlayment and you’ve got big trees overhead, that’s the failure point to watch.
On a 1920s Spanish Colonial Revival bungalow off South Almansor Street, a case we handled with CertainTeed repair in South Pasadena-trained methods, our crew found exactly this. A CertainTeed Landmark roof with severe valley rot where ficus leaves had dammed water for seasons. We tore off the failed section, replaced the rotted decking, installed new CertainTeed Flintlastic underlayment and Landmark shingles in the valleys, then added leaf guards to prevent a repeat. The homeowner avoided a full replacement, and the roof has stayed dry through two rainy seasons since.
CertainTeed Models & Products We Service in Alhambra
We work on the full CertainTeed residential lineup you’re likely to find on Alhambra roofs. That includes Landmark architectural shingles, the most common CertainTeed product we see on 1980s and later re-roofs, XT 25 and XT 30 three-tab shingles from older work, and Presidential Shake luxury shingles on higher-end homes and some custom builds. We also service and replace Flintlastic roofing underlayments, which are the component most often implicated in Alhambra’s valley leak problems.
On parts, we’re pragmatic. We stock genuine CertainTeed shingles and Flintlastic underlayment for warranty-compliant repairs. But we’ll also use quality aftermarket ridge caps, pipe boots, and valley metal when we believe they’ll outperform what CertainTeed specs for a given detail. The goal is a roof that holds up under Alhambra’s specific conditions, not blind brand loyalty.

AfterCertainTeed Service Pricing in Alhambra
CertainTeed repair pricing in Alhambra depends on what we find once we’re on the roof. A single shingle or small valley repair typically falls in the $300 – $700 range. Larger section replacements, such as a full valley with new underlayment and decking, generally run $1,200 – $2,800. A full tear-off and CertainTeed replacement on a typical Alhambra bungalow usually lands between $12,000 and $22,000, driven by roof size, pitch, number of layers being removed, and decking condition. Older homes with three or four layers almost always cost more because the tear-off is heavier and the decking beneath is rarely pristine.
Every estimate starts with a roof inspection. We look at the shingle field, valleys, flashings, and attic ventilation, then give you a written, line-item quote. No vague numbers, no change orders mid-job. Call (866) 705-2978 to schedule a free estimate on your CertainTeed roof in Alhambra.

FAQs – CertainTeed Roofing in Alhambra
We will not shingle over a third or fourth layer, and you shouldn’t let anyone else do it either. Most Alhambra homes with that many layers are already near or over the weight limit for their roof framing. More importantly, those buried layers hide decking rot and structural problems that get worse every season. A full tear-off costs more upfront, but it’s the only way to know what’s actually under the shingles. Call (866) 705-2978 for a tear-off estimate with no obligation.
Granule loss is normal as shingles age, but UV damage accelerates it into visible patterns. Look for shingles that have curled edges, exposed fiberglass mat, or a bald appearance in the center where granules have washed off. In Alhambra, south-facing and west-facing roof planes always show UV damage first. If you’re seeing granules in your gutters every time it rains, that’s accelerated wear. We’ll inspect and tell you whether it’s isolated or systemic.
Gutter cleaning is downstream of the actual problem. The leaves dam water in the valleys themselves, not just in the gutters, and that trapped water sits against the valley metal and underlayment seams until it finds a way through. If your CertainTeed roof has original Flintlastic underlayment, it’s especially vulnerable to this in Alhambra’s fall and winter leaf season. We repair the valley and underlayment, then recommend leaf management so the repair doesn’t fail the same way next year.
Most Santa Ana wind damage on Presidential Shake roofs in Alhambra is confined to ridge caps and exposed hip edges, and that’s repairable. The key is catching it early, before wind-driven rain gets under the shingles and into the decking. We’ll replace the lifted or missing ridge caps, re-adhere loose courses, and assess whether the rest of the roof is solid. In most cases, a few hundred dollars in repair beats a full replacement. Call (866) 705-2978 to schedule a wind-damage inspection.
We stand behind our workmanship on every repair and replacement we do. Manufacturer warranty coverage on CertainTeed products depends on the product line, the installation details, and whether the roof meets CertainTeed’s installation specifications. We’ll walk you through what’s covered and what isn’t before any work begins. For exact warranty terms on your specific roof, call (866) 705-2978 and we’ll review it with you.
