CertainTeed’s Landmark and Presidential Shake lines are common on Los Angeles homes for good reason: they perform well under intense UV, and the color selection fits the stucco and Spanish Colonial Revival architecture you’ll find in Silver Lake, Highland Park, and Hancock Park. But Southern California conditions expose specific failure modes that generic CertainTeed pages don’t address. The Santa Ana winds that tear through the San Fernando Valley every fall test adhesive strips that held fine in milder climates. Coastal fog in Santa Monica and CertainTeed Construction in West Los Angeles, CA areas like Pacific Palisades feeds algae growth that darkens light-colored shingles within five years. And the thermal expansion from 55-degree winter mornings to 95-degree summer afternoons splits shingles that weren’t ventilated properly during original installation.

We are not authorized by CertainTeed. We are an independent service provider with field experience across their full product line. That independence means we can recommend repair when it makes sense, replacement when it doesn’t, and aftermarket alternatives for out-of-warranty work without manufacturer constraints.

Why Trust Rowan Construction Group Los Angeles for Your CertainTeed Construction?

Grant Rowan grew up in the Palms neighborhood, close enough to the Expo Line corridor that he watched construction crews work before he ever picked up a tool himself. He trained at Los Angeles Trade-Technical College, learning to read structural drawings and understand load paths before swinging a hammer with confidence. That background shows in how our crews approach CertainTeed systems: we measure twice, document everything, and don’t invoice until the scope matches the work.

Our technicians are background-checked, uniformed, and trained on CertainTeed’s specific installation requirements. We stock genuine CertainTeed OEM accessories and shingles for warranty-compliant repairs, and we carry quality aftermarket alternatives for out-of-warranty work. Every visit includes a documented photo record as standard - not an upgrade - so you see what we found and what we did.

Under Clause 1 of the Haven Standard, the price is written before anyone starts. Under our 365-Day Done Right Promise, if it’s not done right, we make it right. And if you bring us a competitor’s written estimate, we’ll review it line by line at no charge. “If it’s not written down, it didn’t happen” - that’s how we work.

Common CertainTeed Construction Problems We Fix in Los Angeles

• Granule loss and premature aging on Landmark shingles. The south-facing slopes of Woodland Hills and Encino roofs take a beating. UV intensity in the San Fernando Valley accelerates granule shedding beyond what CertainTeed’s standard warranty anticipates for national averages. We see this most on 12-15 year old Landmark installations where the protective mineral coating has worn thin, exposing the asphalt substrate to further degradation. Our repair replaces damaged shingles with matching CertainTeed OEM product and evaluates whether attic ventilation upgrades can slow future loss.
• Cracking and thermal splitting on Presidential Shake shingles. These luxury shingles are thicker and more dimensional, which makes them beautiful but also more susceptible to the extreme diurnal temperature swings common in hillside neighborhoods from Bel Air to Laurel Canyon. A 40-degree morning that hits 85 by afternoon creates repeated expansion-contraction cycles. We find longitudinal cracks running from the butt edge upward, often on north-facing slopes that stay cooler longer and then heat rapidly. Repair requires careful removal of the damaged course and inspection of the underlayment beneath.
• Adhesive strip failure and wind uplift on NorthGate and Landmark shingles. CertainTeed’s self-sealing strips rely on solar heat activation to bond shingles to the course below. In Los Angeles, Santa Ana wind events can hit before full activation, especially on spring installations. We’ve re-secured lifted shingles in Granada Hills and Northridge after 60-mph gusts peeled back sections that hadn’t thermally sealed. Our repair includes hand-sealing with asphalt plastic cement in wind-prone zones and upgrading to six-nail patterns where code allows.
• Algae staining on light-colored shingles in coastal zones. Gloeocapsa magma thrives in the marine layer that rolls into Santa Monica, Pacific Palisades, and Venice. Blue-green algae colonies show as black streaks that homeowners often mistake for dirt or mold. CertainTeed’s StreakFighter copper-infused granules help but don’t eliminate the problem in persistent fog conditions. We clean affected roofs with manufacturer-approved solutions and can discuss whether darker shingle colors or copper ridge strips make sense at replacement.
• Improper original installation compounding material failure. This isn’t a CertainTeed defect, but it’s the most common issue we encounter. In the 1960s-70s dingbat apartments targeted by LA’s soft-story retrofit mandate, original roofs were often installed with inadequate ventilation, wrong nail placement, or incompatible underlayment. When we repair these buildings under Ordinance 183893, we frequently find that the roof deck itself has degraded from decades of trapped moisture. Our scope includes substrate inspection and documentation, because covering a failing deck with new shingles wastes everyone’s money.

CertainTeed Parts & Our Repair-vs-Replace Approach

For warranty-active CertainTeed roofs, we use genuine CertainTeed OEM accessories and shingles. The manufacturer requires this for claim eligibility, and we document every part number on our photo record. For out-of-warranty repairs, we offer quality aftermarket alternatives that match performance specifications - often at lower cost - and we tell you exactly which route we’re taking before we order materials.

Our repair-versus-replace assessment is honest because our business model depends on it. A localized repair with matching shingles and reinforced underlayment can safely extend a roof’s life by five to seven years. We’ll recommend that when the surrounding shingles show acceptable granule retention and the deck is sound. We’ll recommend full replacement when more than 30% of the field shows failure symptoms, when the underlayment is degraded, or when repair costs approach half the price of replacement.

We stock CertainTeed Landmark and Presidential Shake shingles locally for fast turnaround on Los Angeles repairs. Call (213) 652-7670 for an assessment - estimates are free, and the price is written before any work starts.

Our CertainTeed Service Process - Step by Step

1. 1
   Diagnosis with documentation. We inspect the full roof system, not just the visible damage. For CertainTeed installations, we check granule retention with a visual assessment, test adhesive strip bonding on lifted shingles, and photograph the condition of flashings, valleys, and ventilation. You receive the photo record before we leave.
2. 2
   Written scope and flat price. We specify exact CertainTeed product lines, quantities, and any substrate repairs. The quote includes a written warranty and our 365-Day Done Right Promise. No change proceeds without a signed change order - that’s the discipline that has kept our projects within a few percent of the agreed cost across 4,000-plus jobs.
3. 3
   Repair or installation with OEM-compatible parts. Warranty work uses genuine CertainTeed shingles and accessories. Out-of-warranty work uses quality aftermarket alternatives where appropriate. We follow CertainTeed’s nailing patterns, exposure requirements, and ventilation specifications precisely.
4. 4
   Testing and quality verification. We verify shingle alignment, sealant strip contact, and flashing integrity. On hillside homes in the Hollywood Hills or Pacific Palisades, we pay particular attention to wind uplift resistance and drainage paths.
5. 5
   Final documentation and warranty registration. You receive the completed photo record, written warranty terms, and assistance with CertainTeed warranty registration if applicable. We don’t invoice until the scope matches the work.

FAQs - CertainTeed Construction Service in Los Angeles

Is Rowan Construction Group Los Angeles authorized by CertainTeed?

No. We are an independent CertainTeed service provider, not a manufacturer-authorized dealer. Our expertise comes from field installation and CertainTeed in Culver City and across Los Angeles, not from a certification program. We use genuine CertainTeed OEM parts for warranty-compliant work and quality aftermarket alternatives for out-of-warranty repairs. Call (213) 652-7670 with questions about your specific situation.

Do you use genuine CertainTeed shingles for repairs?

Yes, for warranty-active roofs. CertainTeed requires OEM parts for warranty claim eligibility, and we document every part number. For out-of-warranty repairs, we offer quality aftermarket alternatives that match performance specifications at lower cost, and we explain the trade-off before ordering. Call (213) 652-7670 to discuss your roof’s warranty status.

How long does a CertainTeed Landmark roof last in Los Angeles?

Landmark shingles typically perform 20-25 years in Los Angeles conditions with proper ventilation and maintenance. UV exposure in the San Fernando Valley and thermal cycling in hillside neighborhoods can shorten this by 3-5 years if the attic isn’t ventilated to manufacturer spec. We’ve seen well-ventilated Landmark roofs in Pasadena and South Pasadena exceed 25 years, while poorly ventilated installations in Woodland Hills show significant granule loss at 15. Call (213) 652-7670 for a condition assessment.

Can you repair wind damage on my CertainTeed Presidential Shake roof?

Yes. Presidential Shake shingles are heavier and more wind-resistant than standard architectural shingles, but their thickness also makes them harder to seal properly after lifting. We remove damaged courses, inspect the underlayment for tearing at fastener points, and replace with matching CertainTeed Presidential Shake product. In Santa Ana-prone zones, we upgrade to six-nail patterns and hand-seal vulnerable areas. Call (213) 652-7670 after any wind event - prompt repair prevents water intrusion.

What causes black streaks on CertainTeed shingles?

Gloeocapsa magma, a blue-green algae that feeds on limestone filler in asphalt shingles, causes the black streaks common in Santa Monica, Pacific Palisades, and other coastal Los Angeles neighborhoods. The marine layer provides persistent moisture that inland areas don’t experience. CertainTeed’s StreakFighter copper-infused granules inhibit but don’t eliminate growth in heavy fog conditions. We clean with manufacturer-approved solutions and can discuss copper ridge strips or color selection at replacement. Call (213) 652-7670 for cleaning or replacement options.

Do you offer emergency roof repairs for CertainTeed roofs after a storm?

We prioritize storm damage calls and can typically assess within 24 hours. Our process: temporary tarping to prevent water intrusion, documented photo record of all damage, written repair scope with flat price, and permanent repair using CertainTeed OEM or compatible materials. A live person answers our phones 24/7. Call (213) 652-7670 immediately after storm damage - water intrusion worsens fast in Los Angeles’s occasional heavy rain events.
