CertainTeed Roofing in West Covina, CA | Hollywood Roofing Co
We provide CertainTeed service in Valinda and across West Covina, from inspections and flashings to full tear-off replacements. What makes our CertainTeed work different here comes down to one thing: we actually understand what 60 years of San Gabriel Valley heat does to roofs that were built in the late 1950s through the mid-1970s. If you need a straight answer about your CertainTeed roof, call (833) 589-7971. Estimates are free and come with a line-item written scope.
Why West Covina Residents Choose Us for CertainTeed Service
We’ve torn off and re-roofed hundreds of CertainTeed installations across the San Gabriel Valley, so we know how Landmark and Presidential systems actually hold up under West Covina’s UV load rather than how they look in a showroom. CertainTeed’s CertainTeed sales & service experience runs deep on our crews, and because we install seven leading roofing brands (GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral), we’re not boxed into recommending a single manufacturer. Roland Vega, our owner, learned the trade at LA Trade-Tech and has spent the better part of three decades working roofs across Hollywood and the San Gabriel Valley. He’ll tell you that the same team that inspects your roof can repair or replace it, with no handoff gaps.
As an independent contractor, we work on any brand, but CertainTeed systems are one of the ones we know down to the fastener pattern and attic-ventilation requirements. When you call us for CertainTeed repair in South San Jose Hills or West Covina, you get someone who respects the product without being beholden to the manufacturer.

Common CertainTeed Roofing Problems We Solve in West Covina
- Granule loss and asphalt embrittlement on Landmark shingles. West Covina’s intense summer sun bakes south- and west-facing slopes until the asphalt loses its oils and the protective granules let go. You end up with bald, blistered fields where the fiberglass mat is exposed on the exact slopes that catch the most UV damage. This is the single most common CertainTeed failure we see from the 10 freeway north to the 60.
- Sealant strip failure and wind-lifted tabs on overlaid shakes. In the 91790 and 91791 ZIP codes near the 10 freeway, a lot of original shake roofs were overlaid rather than torn off. The trapped heat and poor nailing surface underneath cause CertainTeed shingles laid over those shakes to lose their sealant bond, so tabs lift and curl with the first good Santa Ana wind.
- Premature decay at penetrations and flashings. Vent boots, valley metal, and step flashing are the first things to go on any aging CertainTeed roof, but in West Covina, the original 1960s homes rarely got proper attic ventilation. Once a vent boot cracks and winter rains find soft board sheathing, rot moves fast in the dry heat that follows.
- Underlayment breakdown under low-pitch CertainTeed systems. Original mid-century ranch roofs in West Covina often have almost no ridge or soffit venting, so heat builds and bakes the felt from below. By the time we’re called, the shake or shingle field above it has already claimed the underlayment.
- Cupped and split shakes trapping heat under a second layer. Back to the overlay issue again. Original wood shakes dry out in the San Gabriel Valley heat, cup, and split, then trap even more heat under whatever CertainTeed shingle was laid over them. This warps the nailing surface and softens the plywood deck, which drives up the cost of any later tear-off.
CertainTeed Service in West Covina: What Local Conditions Mean for Your Roof
Here’s the thing that catches most out-of-area bidders off guard. In the 91790 and 91791 ZIP codes, especially the neighborhoods near the 10 freeway, a large share of original wood-shake roofs got a second layer slapped on top decades ago. That second layer is now failing fast, and the dry heat causes the shakes underneath to cup and split, which softens the plywood sheathing from below. Before we bid any CertainTeed tear-off in West Covina, we probe the deck and count existing layers. A roof that looks like a simple one-layer replacement can easily be a three-layer tear-off with rotted sheathing underneath. Most out-of-town estimates miss that because they never walk the roof or check the attic. We do both before we put a number in front of you. That’s the difference between a bid you can trust and one that falls apart the moment the shingles come off.
CertainTeed Models & Products We Service in West Covina
We work across the full CertainTeed line that shows up on West Covina homes: Landmark architectural shingles, including Landmark 30 and Landmark Pro; Xtreme IR reflective architectural shingles for anyone trying to drop attic temperatures on a south-facing ranch; Presidential Shake and Presidential shake-look profiles for the higher-end hillside homes; and Cedar Impressions or Cedar Valley profiles where a wood-shake look is part of the house’s character. We use genuine CertainTeed shingles and matching accessories (starter, ridge, and underlayment) when the field is staying in the same line, and quality aftermarket flashings, vent boots, and membranes where they perform as well or better. What we stock locally is the common CertainTeed colorways and accessories, so CertainTeed repair in La Puente and West Covina doesn’t wait on a distributor run from Pomona or City of Industry.

AfterCertainTeed Service Pricing in West Covina
Pricing depends on how many layers are coming off, what the deck looks like underneath, and which CertainTeed line you’re going back with. A straightforward flashing or vent boot repair on a Landmark roof in West Covina typically starts around $450. A full tear-off and re-roof on a mid-century ranch, deck probing included, usually falls between $9,500 and $18,000 depending on square footage, pitch, and whether we’re pulling one layer or three. Every quote we give includes the layer count, deck condition, ventilation correction, and the CertainTeed product line written out line by line. What drives the price more than anything in West Covina is the overlay factor. One layer comes off fast. Three layers with soft sheathing takes real labor. Call (833) 589-7971 and we’ll walk the roof and give you an honest number, not a guess.

FAQs – CertainTeed Roofing in West Covina
No. We won’t do it, and you shouldn’t let anyone else do it either. Adding a third layer over cupped, split shakes and already-stressed CertainTeed shingles traps heat, rots the deck from below, and voids any shot at a clean nail pattern. The honest route is a tear-off to the deck, which lets us see whether the sheathing is still sound. Call (833) 589-7971 and we’ll probe the deck and give you a real answer.
For most West Covina ranch roofs, Landmark architectural shingles hit the right balance of cost, weight, and UV resilience. If the south and west slopes are getting blasted, we look at Landmark Pro or Xtreme IR for the reflective benefit. Presidential is overkill for a low-pitch ranch, and the shake-look lines add cost without adding lifespan on this style of roof.
That’s trapped heat. West Covina’s mid-century homes were built with minimal ridge or soffit venting, so summer attic temps climb well past what a shingle field should endure. The underside of the shingle bakes, the asphalt blisters, and granule loss follows. Fixing the shingles alone won’t fix the root cause. The ventilation has to be corrected as part of the repair or replacement, or the same thing happens to the next roof.
We’re an independent roofing contractor, not a CertainTeed-authorized installer. That means we install CertainTeed materials because they’re the right fit for the home, not because a manufacturer program tells us to. CertainTeed’s material warranty still applies to the shingles themselves; what changes is the workmanship warranty, which comes from us, not from CertainTeed. That’s a question worth asking any roofer. Call (833) 589-7971 and we’ll walk you through what’s covered either way.
If the flashings and vent boots have failed but the shingle field is still holding granules and lying flat, Roof Repair – West Covina makes sense. If the field is granule-bald, blistered, or lifting at the tabs, or if the deck under the shingles is soft when probed, you’re looking at replacement. We’ll tell you which one you actually need, not which one pays us more. Call (833) 589-7971 for a free estimate and we’ll show you what’s going on up there.
