CertainTeed Construction in Thousand Oaks, CA | Mason Remodeling Co Thousand Oaks
We provide independent CertainTeed construction service throughout Thousand Oaks, from full roof replacements to siding repair and home additions. Our crews know how CertainTeed Landmark shingles, Cedar Impressions siding, and FlintBoard hold up to Ventura County’s hot, dry summers and Santa Ana wind events. Call (805) 309-3386 for a free estimate, and we’ll get someone out to look at your project.
Mason Remodeling Co, a Thousand Oaks General Contractor, has worked with CertainTeed products for years, and we’re not tied to any manufacturer program. That means we recommend what actually works for your home, not what a corporate rep tells us to push. Isaac Pruett, our owner, grew up in Los Angeles and trained at Los Angeles Trade-Technical College before running crews across the region. He’s been working on Thousand Oaks homes long enough to know which CertainTeed products hold up here and which ones don’t.
Why Thousand Oaks Residents Choose Us for CertainTeed Service

CertainTeed makes good roofing and siding. But a product is only as good as the crew installing it. We’ve torn off enough failing CertainTeed roofs in Thousand Oaks to know exactly where the weak points are: south- and west-facing slopes, ridge lines, and flashing details that get baked by the sun year after year.
We use genuine CertainTeed starter strips, hip-and-ridge caps, and matching accessory shingles on every repair. No generic substitutes that void warranty intent. When a discontinued siding profile needs work, we source compatible aftermarket trim coils and color-matched fasteners, and we replace full sections rather than patching so the finish ages evenly. You’ll see one consistent exterior, not a patchwork.

Common CertainTeed Construction Problems We Solve in Thousand Oaks
- Landmark shingle granule loss. Prolonged UV exposure and Santa Ana wind abrasion strip granules from shingles on south- and west-facing roof planes. We see this constantly on homes in the Wildwood and Lynn Ranch hillsides. The fix is usually a partial or full reroof with Landmark Pro or Grand Manor profiles.
- Cracked or lifted ridge caps on Presidential Shake profiles. Original nails were overdriven during 1980s tract construction, and decades of thermal expansion plus wind have worked those caps loose. We re-cap ridge and hip lines with matching Shadow Ridge caps and correct the fastening.
- Cedar Impressions siding warping at butt joints. Thermal expansion on unshaded hillside elevations causes panels to cup and pull away from the wall. We replace full courses with properly spaced butt joints, which prevents repeat failure.
- FlintBoard swelling at bottom edges. Irrigation overspray or poor drainage keeps the fiber cement saturated, and the material swells. We correct the drainage first, then replace the damaged sections so the problem doesn’t come back.
- Flashing failures at roof-to-wall intersections. Thousand Oaks homes built in the 1970s and 80s often used corrodible base flashing. We replace with high-temperature ice-and-water shield and CertainTeed-compatible flashing before installing new shingles.
CertainTeed Service in Thousand Oaks: What Local Conditions Mean for Your Equipment

Here’s a fact that matters for anyone with an older CertainTeed roof in Thousand Oaks: the Wildland-Urban Interface zone covers most hillside neighborhoods here, and Ventura County requires Class A fire-rated roof assemblies in that zone. Homes in Lynn Ranch and Wildwood that were built in the 1980s with original CertainTeed Landmark shingles often don’t meet that standard anymore. Our crews routinely upgrade those original roofs to current CertainTeed Grand Manor or Carriage House profiles, which meet the fire code while keeping the HOA-approved shake-look aesthetic. That’s not something you’d run into in Simi Valley or Moorpark the same way, because the WUI boundaries and HOA rules differ.
Our crew replaced a failing CertainTeed Landmark roof on a two-story Mediterranean in the Lynn Ranch neighborhood. The original shingles showed heavy granule loss on the west slope and lifting along the ridge line from decades of Santa Ana winds. We stripped to the deck, replaced water-damaged plywood, added a high-temperature ice-and-water shield, and installed CertainTeed Landmark Pro in Weathered Wood, then reflashed and re-capped all ridge and hip lines with SureStart starter strips and matching Shadow Ridge caps. The job finished before the next red-flag wind event, and the owner’s insurance inspection passed on the first visit.

FAQs – CertainTeed Construction in Thousand Oaks
Can I keep my CertainTeed Landmark shingles if only the ridge caps are cracked on my Thousand Oaks home?
Yes, in most cases. If the field shingles still have granules and aren’t curling, we can replace the ridge caps and hip lines with matching CertainTeed Shadow Ridge caps. We inspect the underlying fasteners and flashing before quoting. Call (805) 309-3386 for a free evaluation of your ridge condition.
My 1970s Lynn Ranch home has original CertainTeed Cedar Impressions siding. Can you match the color for a small repair?
CertainTeed discontinued some 1970s Cedar Impressions color lines, and even current colors fade differently with sun exposure. We source compatible aftermarket trim coils and color-matched fasteners, and we replace full sections rather than patching so the finish ages evenly. If you only need one panel, we’ll tell you honestly whether a match is realistic or whether full-section replacement makes more sense. Call (805) 309-3386 for a siding assessment.
Do CertainTeed Landmark shingles meet Thousand Oaks’ wildfire Class A requirement?
Current CertainTeed Landmark and Landmark Pro shingles carry a Class A fire rating when installed with the full CertainTeed system, including starter strips and ridge caps. However, older Landmark roofs from the 1980s may not meet current Wildland-Urban Interface standards because the assemblies degrade over time. We routinely upgrade those roofs to CertainTeed Grand Manor or Carriage House profiles, which meet the fire code while keeping the HOA-approved aesthetic. Call (805) 309-3386 and we’ll check your roof’s classification during a free inspection.
What causes granule loss on the west-facing slope of my CertainTeed roof in Thousand Oaks?
West-facing slopes in Thousand Oaks get hit with the most intense afternoon sun and the brunt of Santa Ana winds. The combination bakes the asphalt coating, releases granules, and accelerates aging far faster than east- or north-facing slopes. Common fixes range from localized repair of granule-loss areas to full reroofing, depending on how much surface area is affected. Call (805) 309-3386 for an exact quote, estimates are free.
Can you add a second story to my Thousand Oaks tract home and keep the exterior looking consistent with my CertainTeed siding?
Yes, and this is common work for us. We specialize in Bathroom Remodeling in Thousand Oaks and integrate new CertainTeed siding and roofing with the existing exterior by matching profiles, colors, and installation methods. For older homes, we may recommend full-section replacement of adjacent siding so the new and old surfaces age evenly. It’s more work than patching, but the result looks original. Call (805) 309-3386 to talk through your addition.
