Why West Hills Residents Choose Us for CertainTeed Service
CertainTeed products run through a lot of West Hills homes, especially the Presidential Shake and Landmark roofs on the 1960s-1980s custom builds that climb the hills south of Victory. Our crews have spent years working on those roofs, and we’ve learned what the manufacturer’s warranty doesn’t tell you: that Santa Ana gusts, intense summer UV, and undersized 1970s drainage all stress CertainTeed materials in ways the spec sheets never anticipated. We’re not factory-affiliated, but we install genuine CertainTeed components where it matters. Isaac Pruett, our owner, grew up in Los Angeles and trained at LATTC before putting in years on job sites across the region, and he built this company around one idea: tell the homeowner what’s actually wrong, what it costs, and what we’ll do about it. That’s how we handle every CertainTeed job in West Hills.

Common CertainTeed Construction Problems We Solve in West Hills
- Presidential Shake tabs lifting on exposed ridges. The shake-profile tabs on Presidential Shake asphalt shingles are vulnerable to Santa Ana wind gusts of 40-60 mph, especially on homes built upslope with no wind break. We see it most often on the custom builds closer to the Santa Susana foothills, where the ridge lines catch the full force of the wind and tabs start peeling back within a decade. We replace the damaged shingles and check the entire slope for loose tab adhesion before the next wind event.
- Landmark shingles with premature granule loss on south-facing planes. West Hills summers push roof surface temperatures well past 140 degrees on south-facing slopes. That sustained UV and thermal cycling breaks down the asphalt binder in Landmark shingles faster than on north-facing planes, causing granule loss and bald spots years earlier than expected. We inspect the entire south elevation and recommend whether spot repair or a full re-roof makes sense for your budget.
- Cedar Impressions panels warping at butt joints from drainage overflow. When the original 1970s hillside drainage systems south of Victory Boulevard spill over during heavy winter rains, sheet flow runs directly against foundation walls and wicks up into the bottom courses of Cedar Impressions polymer siding. The butt joints warp, the panels pull away from the wall, and moisture gets trapped behind them. We repair this by fixing the drainage first, then replacing the affected siding courses so the problem doesn’t come back every rainy season.
- Monogram vinyl siding buckling behind stucco transitions. West Hills winter rains find their way behind stucco transitions where the original flashing has failed, trapping moisture against Monogram vinyl siding. The siding buckles outward and the trapped water starts degrading the sheathing behind it. We pull the affected panels, correct the flashing, and re-install the siding so it can breathe and drain properly.
- Corroded valley flashing on 1970s hillside roofs. Original valley flashing on West Hills homes built from the 1960s through the 1980s was often undersized galvanized metal that corrodes after 40-50 years of exposure to Santa Susana drainage patterns and thermal cycling. Once it fails, water runs under the shingles and into the decking. We re-flash valleys with wider profile metal and install CertainTeed WinterGuard underlayment beneath, which stops the leak at its source instead of chasing it with caulk.
CertainTeed Service in West Hills: What Local Conditions Mean for Your Equipment
South of Victory Boulevard, many 1970s hillside homes in West Hills still run on their original drainage systems, and those systems were not sized for today’s stormwater flows. When heavy winter rain hits the Santa Susana slopes, the runoff exceeds what those old drains can carry, and the excess sheet flow runs directly against foundation walls. For CertainTeed owners, that means Cedar Impressions siding at the base of the wall starts wicking moisture, warping at the butt joints, and trapping water behind the panels. It’s a failure pattern we see regularly in the neighborhoods south of Victory, and it does not show up the same way in flat-lot communities a few miles away. The fix is never just replacing the siding. We trace the drainage first, correct the grading or add a diverter if needed, then repair the siding so the next winter rain doesn’t undo the work. If your CertainTeed siding is warping at the base of your walls, call (805) 309-3386 and we’ll tell you whether it’s a siding problem, a drainage problem, or both.
CertainTeed Models & Products We Service in West Hills
Our crews work on all four major CertainTeed product lines common in West Hills: Presidential Shake asphalt shingles, Landmark asphalt shingles, Cedar Impressions polymer siding, and Monogram vinyl siding. For roofing, flashing, and siding repairs we install genuine CertainTeed replacement components, because the shingle profiles and fastener patterns are proprietary and aftermarket parts simply don’t align correctly. For trim and starter strips, we use OEM only when wall geometry demands it. Otherwise we fit code-approved aftermarket flashing that actually outperforms the original under West Hills wind uplift conditions. That judgment call comes from years of seeing what holds and what doesn’t on these hillside homes.

AfterCertainTeed Service Pricing in West Hills
| Service | Price Range |
|---|---|
| Roof Replacement | $8,000 – $20,000 |
| Roof Repair | $400 – $1,800 |
| Metal Roof Installation | $15,000 – $40,000 |
Those ranges reflect what we see across West Hills, where hillside access, steep slopes, and the need for drainage corrections often push costs toward the upper end. What drives the final number is the roof’s pitch, the condition of the decking, whether we’re re-flashing valleys or adding underlayment, and how much siding or drainage work ties into the roofing scope. Every estimate we give is a written line-item quote before any work starts, and that price does not change unless you change the scope. Call (805) 309-3386 to schedule your free estimate. We’ll measure the roof, check the drainage, and give you a number you can plan around.

FAQs – CertainTeed Construction in West Hills
Presidential Shake shingles lift on West Hills hillside homes because the tab adhesive loses its grip after years of intense summer heat, and then Santa Ana wind gusts of 40-60 mph catch the exposed tabs on ridgelines with no natural wind break. The custom homes built on the upper slopes are the ones we see this on most. If your tabs are lifting, we can replace the damaged shingles and re-secure the rest before the next wind event. Call (805) 309-3386 for an exact repair quote, and we’ll inspect the entire slope while we’re there.
Yes, we can repair warped Cedar Impressions siding, but the repair only lasts if we fix the drainage problem that caused the warping in the first place. For Bathroom Remodeling in West Hills and other projects, we apply this same fix-the-root-cause approach. On West Hills hillside homes, that usually means correcting 1970s undersized drainage that sends sheet flow against the foundation wall. We replace the warped panels with new Cedar Impressions and add a diverter or regrade the area so the water moves away from the wall. If you’re seeing warping at the base of your siding, call (805) 309-3386 and we’ll tell you whether it’s a siding job, a drainage job, or both.
For West Hills homes with significant south-facing roof planes, we recommend Landmark or Presidential Shake shingles in lighter color blends, which reflect more solar radiation and reduce thermal stress on the asphalt binder. The darker blends absorb more heat and show granule loss earlier on south-facing slopes. The right choice depends on your roofline, your home’s exposure, and how much direct afternoon sun your roof takes. Call (805) 309-3386 for a free assessment and we’ll recommend a specific product and color for your home’s orientation.
We remove the old flashing, cut back the shingles, install CertainTeed WinterGuard underlayment at the transition, and re-flash with wider profile metal than the original. That’s the full fix. Patching with caulk or tar never lasts on West Hills hillside roofs, because the thermal expansion and contraction keeps pulling the patch material apart. If your valleys or wall transitions are leaking, call (805) 309-3386 and we’ll tell you whether a re-flash is enough or if you need a full re-roof.
At 20 years old, a Landmark roof in West Hills is approaching the end of its service life, especially if it has significant granule loss on the south-facing planes or if you’ve already had multiple leaks. Repair is worth it if the damage is localized and the remaining shingles still have adhesion and granule coverage. If you’re seeing widespread granule loss, lifting tabs, or recurring leaks, replacement is usually the cheaper option over the next five years. We’ll give you an honest assessment either way. Call (805) 309-3386 and we’ll inspect the roof and tell you what’s actually left in it.
