CertainTeed Roofing in Woodland Hills, CA | Mercer Roofing Co Woodland Hills
Our Woodland Hills Roof Repair team provides independent CertainTeed roofing service across Woodland Hills, from full replacements to targeted decking and flashing repair. What makes our CertainTeed work different here comes down to one thing: we know how these specific shingles fail under triple-digit Valley heat and Santa Ana wind, because we’ve repaired them on hundreds of Woodland Hills homes. If your CertainTeed roof is showing its age, call (341) 217-2677 for a free estimate and a written price before any work starts.
Why Woodland Hills Residents Choose Us for CertainTeed Service
Grant Whitlock, owner of our Woodland Hills Roofing Company, has been putting roofs on homes across Woodland Hills for well over a decade. He grew up in Los Angeles and learned the trade through the construction technology program at Los Angeles Trade-Technical College, and he has spent more than his share of July afternoons up in the Warner Center corridor where the heat alone tells you whether a roof was done right. Our crews have worked on CertainTeed Landmark, Presidential Shake, Belmont Tile, and Flintlastic SA systems long enough to know exactly where they fail in this climate.
We are an independent CertainTeed service provider, not a manufacturer-authorized dealer. That matters because we are free to recommend the repair that actually protects your home rather than the one that protects a brand relationship. If a repair is enough, Grant will tell you that in writing. If it is not, he will tell you that too, and explain why the next Woodland Hills heat wave will find the weak spot. Every visit starts with a background-checked, photo-badged technician whose name and photo you receive before they arrive. You know who is coming to your door. For a deeper look at our broader brand coverage, see our CertainTeed sales & service page.
Nobody wants a stranger poking around their roof. We send you the technician’s name and photo ahead of the appointment, and that person arrives in a marked uniform with a photo ID badge. It is the simplest way we know to remove the stranger-at-the-door risk from roofing. Every repair includes a written guarantee for 365 days. If the work fails within a year, we return and make it right at no charge. No fine print, no phone tag. A live person answers our phone 24/7, including the number at the bottom of this page.

Common CertainTeed Roofing Problems We Solve in Woodland Hills
- Granule loss on south-facing Landmark slopes. Woodland Hills routinely sees summer days above 110°F, and the UV exposure on south-facing pitches strips the protective granules off CertainTeed Landmark shingles faster than on other exposures. What is left behind is bare asphalt that bakes, cracks, and eventually leaks. We often find this on mid-century ranches where the original ventilation was never upgraded to handle the heat.
- Sealant strip drying and tab lifting during Santa Anas. The sealant that bonds Landmark tabs can dry and crack under prolonged UV exposure. Once that bond fails, a Santa Ana gust gets under the tab and lifts it. Homes north of Ventura Boulevard see this first, because the corridor funnels wind down from the foothills and hits the eave rows hardest.
- Thermal blistering and splitting on Presidential Shake. Luxury architectural shingles are thick, which means they hold heat longer. On low-ventilation ranch roofs in Woodland Hills, the repeated expansion and contraction cycle causes blisters on the shingle surface that eventually split through the nail line. We see this most often on older homes where ridge and soffit ventilation is minimal.
- Flintlastic SA membrane laps peeling on low-slope sections. Many Woodland Hills homes have flat or low-slope additions. Flintlastic SA self-adhered membrane holds up well, but prolonged 100°F heat followed by winter rain can cause the lap seams to peel back if they were not rolled properly at install. We fix the laps, inspect the underlying decking, and re-coat where needed.
- Tile shifting and cracking on hillside Belmont Tile roofs. South of Ventura Boulevard, clay and concrete tile roofs are common on hillside homes. After a heat wave, tile expansion combined with Santa Ana gusts causes tiles to shift or crack. Homeowners often miss the damage until the first rain finds the underlayment. We replace the broken tiles and inspect the waterproofing layer underneath.
CertainTeed Service in Woodland Hills: What Local Conditions Mean for Your Equipment
Here is the one fact about Woodland Hills that changes how CertainTeed roofs behave here compared to Simi Valley, Agoura Hills, or even West Hills: the Ventura Boulevard corridor acts as a wind tunnel during Santa Ana events. The boulevard runs east-west, and when those northeast winds come down from the foothills, the buildings and street grid funnel the gusts, concentrating them on the first row of eaves on homes north of the boulevard. We have climbed onto roofs where the only lifted tabs on the entire structure were the first two rows above the eave on the north side. The rest of the roof was fine. If you live north of Ventura Boulevard and your CertainTeed Landmark shingles are lifting at the eave line after a wind event, that is not a coincidence. It is geography. Our repair approach accounts for it by checking the eave rows first, and when we replace roofs in that zone, we use a sealed eave starter course and high-wind nailing patterns to keep those first rows locked down. This is the kind of thing that only shows up from actually working in Woodland Hills, roof after roof, not from a training manual.
CertainTeed Models & Products We Service in Woodland Hills
We service the full range of CertainTeed roofing systems common in this area. That includes the Landmark Series architectural shingles, the Presidential Shake luxury line, Belmont Tile concrete tile, and Flintlastic SA self-adhered modified bitumen for low-slope sections. When we install or repair, we use genuine CertainTeed-branded accessories like DiamondDeck underlayment and CertaFlash pipe boots where the roof needs consistent thermal performance. For older discontinued CertainTeed lines, we will compare OEM versus premium aftermarket options honestly and recommend replacement only when a repair would leave your roof vulnerable to the next heat wave. We keep common Landmark colors and DiamondDeck underlayment stocked locally for faster Woodland Hills turnaround.

AfterCertainTeed Service Pricing in Woodland Hills
Most CertainTeed repairs in Woodland Hills land between $350 and $900, depending on the size of the repair and whether decking needs replacement. A full CertainTeed Landmark roof replacement on a typical Woodland Hills ranch home usually runs $12,000 to $18,000. What drives the price is the condition of your decking, the pitch of your roof, and whether you have low-slope sections that need membrane work. Every estimate is free and every price is written before work begins. You will not get a change order surprise after the tear-off reveals bad plywood, because we inspect and price the decking as part of the initial scope. Call (341) 217-2677 to schedule your free CertainTeed roof estimate, and we will have a written line-item price for you before you commit to anything.

FAQs – CertainTeed Roofing in Woodland Hills
Woodland Hills heat accelerates granule loss on CertainTeed Landmark shingles because the asphalt core softens at the sustained temperatures this neighborhood sees every summer, which loosens the bond between the granules and the shingle surface. South-facing slopes lose granules first, exposing bare asphalt that then cracks under UV exposure. We regularly replace Landmark shingles on Woodland Hills roofs that are only ten to twelve years old, where the same roof in a coastal microclimate would have years of life left. If your south-facing slope is looking patchy, call (341) 217-2677 for a free inspection and a written repair price.
Presidential Shake shingles are heavy and generally hold up to wind better than lighter architectural shingles, but they are not immune to Woodland Hills conditions. The greater risk here is thermal blistering from heat retention on poorly ventilated roofs, especially on older ranch homes, which weakens the shingle before the wind even arrives. Once a shingle blisters and splits at the nail line, a Santa Ana gust can tear it loose. We recommend a ventilation check with any Presidential Shake repair in Woodland Hills, because the heat problem and the wind problem are connected. Call (341) 217-2677 for an exact assessment, free of charge.
For low-slope sections on Woodland Hills ranch homes, Flintlastic SA self-adhered modified bitumen is the CertainTeed product we recommend most often. It handles the heat better than torch-down or older built-up systems, and it holds up to the rare but intense winter rains that test low-slope waterproofing here. The key is proper lap installation, because we have seen Flintlastic seams peel back after prolonged 100°F heat when the laps were not rolled with enough pressure at install. We install it the way the manufacturer specifies, and we warranty the workmanship for 365 days.
In most cases, you can repair just the damaged tiles. We replace cracked or shifted Belmont Tile pieces individually and inspect the underlayment underneath for heat damage or tears. The underlayment is the real waterproofing layer on a tile roof, so the condition of that layer determines whether you need a larger repair. If the underlayment is intact, a targeted tile replacement is usually enough. If the underlayment is failing, we will tell you exactly what that means and give you a written price for the scope you actually need. Estimates are free. Call (341) 217-2677.
Homes south of Ventura Boulevard in Woodland Hills sit on hillside terrain with more direct exposure to afternoon sun and less wind break from the foothills, which accelerates UV breakdown of CertainTeed shingle surfaces. Many of those homes also have tile roofs, and tile roofs fail differently, through underlayment deterioration and tile cracking rather than shingle granule loss. The combination of slope, sun angle, and roofing material makes the failure patterns look faster and more dramatic. The fix is the same: inspect early, repair the specific failure, and get a written price before you commit. Call (341) 217-2677 and we will come out and tell you what is actually going on up there.
