CertainTeed Roofing in Alhambra, CA | Hollywood Roofing Co
We provide independent CertainTeed roofing service across Alhambra, from 91801 up through 91896, and also offer CertainTeed service in San Gabriel. What sets our CertainTeed work apart here is that we’ve spent years fixing the two failure patterns this city sees constantly: Spanish-tile roofs where the original underlayment has turned to dust beneath tile that still looks fine, and flat-roof rear additions that pond water after winter storms. Call (833) 589-7971 and we’ll tell you honestly what your roof needs, whether that’s a targeted repair or a full replacement.
Why Alhambra Residents Choose Us for CertainTeed Service
We’ve torn off and re-roofed enough CertainTeed Landmark and Presidential installations across the San Gabriel Valley to know exactly how these shingles age under years of UV baking followed by concentrated winter rain. That matters in Alhambra, where summers bake a roof for months before January storms test every seal strip and flashing joint. Roland Vega, our owner, learned the trade at Los Angeles Trade-Technical College and grew up in Los Feliz, close enough to the Hollywood Hills to understand what a punishing Santa Ana wind does to a roof that wasn’t installed right. As an independent contractor, we handle CertainTeed products on their merits. That means proper nailing, correct underlayment, and an honest decking assessment, not a sales pitch tied to a manufacturer’s warranty program. We also offer CertainTeed sales & service across the broader region, and we bring that same depth of product knowledge to every Alhambra job.

Common CertainTeed Roofing Problems We Solve in Alhambra
- Granule loss and surface crazing on Landmark shingles. South- and west-facing slopes in Alhambra take relentless UV exposure through the San Gabriel Valley’s hot, smoggy summers. The shingle looks intact from the street while the mat beneath is thinning, which is why we check granule adhesion up close rather than judging a roof from the ladder’s base.
- Seal-strip failure on Landmark and Presidential tabs. Thermal cycling, hot days and cool nights, slowly breaks the adhesive bond. Then a Santa Ana wind lifts loose tabs along hip and ridge caps. We see this most often on older CertainTeed installs where windward edges face the foothills.
- Nail-line and exposed-fastener corrosion where shingles meet flashing. Concentrated winter storms find these joints first. Alhambra’s rainy months are short but intense, and water driven into a corroded wall or valley flashing spreads fast through the decking.
- Underlayment breakdown beneath Spanish tile. The original felt or membrane beneath many 1920s – 40s Alhambra tile roofs is 80 years old. It looks like dust when we lift the field tile, which itself appears perfectly sound. The leak reads as a ceiling stain far from any missing tile, and the fix is lifting tile and replacing what’s beneath it, not re-roofing.
- Flat-roof ponding on rear additions along Main and Valley. Built-up roofs and CertainTeed shingle transitions meet at awkward angles. Water sits, degrades the membrane, and finds the seam. We re-flash the transition and repair the ponding area so the water stops collecting where it shouldn’t.
CertainTeed Service in Alhambra: What Local Conditions Mean for Your Equipment
Alhambra’s 1920s – 40s Spanish-tile homes near Alhambra Park and the 91801 flats are the classic post-storm call we get every January. The original underlayment has disintegrated, so water shows up as interior ceiling stains far from any visible damaged tile. A homeowner looks at their roof, sees tile that appears intact, and assumes the leak must be coming from somewhere else. It isn’t. The felt beneath is dust. A roof doesn’t ask for much, just that you pay attention before it has to ask loudly. That’s the situation we walk into repeatedly in Alhambra, and it’s one a generic CertainTeed page never mentions.
After a big January storm we were called to a 1930s Spanish Colonial Revival near Alhambra Park in 91801 where the ceiling was stained in a room well away from any cracked tile. The original felt underlayment had turned to dust under field tile that looked fine from the ladder. We lifted the tile, replaced the failed underlayment and valley flashing, and reinstalled the same tile. The leak stopped without a full re-roof. On the flat-roof rear additions along Main and Valley, we routinely patch ponding and re-flash the transition where CertainTeed shingles meet the built-up roof. If you’re seeing stains after a storm and can’t figure out why, call us before the next rain finds the same path.
CertainTeed Models & Products We Service in Alhambra
We work on the full CertainTeed line that shows up on Alhambra homes. Landmark architectural shingles cover most single-family bungalows and Spanish-style homes. Presidential and Presidential Shake appear on larger or higher-end properties, and their extra thickness is worth discussing on west-facing slopes where UV exposure is brutal. XT25 and XT30 enhanced architectural shingles show up on 1960s – 80s apartment buildings along Main and Valley, where owners often prioritize cost per square over curb appeal. Under tile roofs we install CertainTeed underlayments, DiamondDeck and RoofRunner, as the replacement layer when the original felt fails. Where the existing roof is CertainTeed, we use genuine CertainTeed shingles and underlayments so the assembly stays consistent. Where the brand doesn’t affect performance, flashing, vent boots, and edge metal, we use quality aftermarket parts that do the job without padding the invoice.
We stock common CertainTeed colors and profiles for fast Alhambra turnaround, and we can order any Landmark or Presidential color within a couple of days. Our Alhambra service area covers 91801, 91802, 91896, and 91899, so we’re usually close by when a repair can’t wait.

AfterCertainTeed Service Pricing in Alhambra
Cost depends on what we’re actually fixing. A small leak repair around flashing or a seal-strip issue typically runs a few hundred dollars. Replacing failed underlayment beneath tile is more involved, since we lift and reset the field tile, and that work lands in the $1,800 – $4,500 range depending on the roof’s size and pitch. A full CertainTeed Landmark re-roof on an Alhambra bungalow generally falls between $9,000 and $16,000, with Presidential Shake running higher due to material cost. What drives the price most is decking condition. On 80-year-old homes, we discover rotted sections of decking more often than not, and that’s a change order only after we show you the damage. Call (833) 589-7971 to schedule a free estimate, and we’ll walk you through what your roof actually needs, line by line.

FAQs – CertainTeed Roofing in Alhambra
The tile is probably fine. The underlayment beneath it has failed. Those 1920s – 40s Alhambra homes were built with felt that’s now 80 years old, and when it disintegrates, water passes through the tile roof without a single tile cracking or shifting. The fix is lifting the tile, replacing the underlayment and flashing, and reinstalling the same tile. Call (833) 589-7971 for an inspection before the next storm.
Yes, when installed correctly. Landmark shingles are built for heavy sun, but the key is proper nailing and seal-strip adhesion. We check nail placement on every repair because thermal cycling and wind uplift expose installation shortcuts fast in Alhambra. If you have a slope facing the foothills that takes direct Santa Ana wind, we can discuss whether Landmark or the thicker Presidential line makes more sense.
We do. We install CertainTeed DiamondDeck and RoofRunner under tile assemblies, and under shingles where the roof is already CertainTeed. The underlayment is the waterproofing layer, the tile or shingle is the armor. If the underlayment fails, the roof leaks regardless of what’s on top of it.
Usually it’s a structure and flashing problem rather than a shingle problem. Flat roofs on Alhambra rear additions along Main and Valley typically need re-flashing at the transition where the CertainTeed shingle roof meets the built-up roof. The ponding itself is a slope issue, and we repair the membrane and re-flash the seam so water stops lingering there.
In most cases, yes. CertainTeed’s color lines are consistent enough that we can match Landmark and Presidential profiles, though exact color match depends on how much sun fading the existing shingles have taken. We’ll tell you honestly if a patch will be visible and whether it’s worth replacing that whole plane instead. Call (833) 589-7971 and we’ll assess it in person.
