How CertainTeed Products Fail – and How We Fix Them

CertainTeed makes a solid product, but every roof fails eventually, and the way a CertainTeed roof fails tells you a lot about what the next installation needs to get right. Here’s what we see across Woodland Hills neighborhoods, from the flats of the Valley floor up into the hillside streets near the 101.

• Landmark and Landmark Pro granule loss on south-facing slopes. The Landmark line is the most common CertainTeed shingle on Woodland Hills homes, and on slopes that bake in direct sun all day, the granules start loosening around year 12 to 15. The shingle mat gets brittle underneath. When we install Landmark or Landmark Pro now, we check the decking for heat damage and typically recommend an underlayment rated for high-heat exposure, which most original installations skipped.
• Presidential Shake TL shingles lifting at the butt edge. CertainTeed’s heavy laminated shake-style shingles are beautiful but they catch wind differently than standard architectural shingles. In Woodland Hills, the Santa Ana winds coming down through the canyons will grab a loose butt edge and start peeling shingles one at a time. The fix is usually a combination of a 6-nail pattern instead of 4, and replacing the sealant strip properly rather than relying on the factory adhesive, which loses grip after enough heat cycles.
• Northgate and Highland Slate cracked tabs from improper nailing. When we tear off a CertainTeed slate-look roof that’s only 8 or 10 years old, the cracked tabs are almost always the result of the original installer nailing too high and too deep. CertainTeed is specific about nail placement, and a high nail leaves the tab unsupported. On re-installation, every nail goes where CertainTeed’s spec says it goes, and our crew checks as they go.
• XactiVent ridge vent failure in Woodland Hills heat. CertainTeed’s ridge vent products work, but the plastic versions can warp over time in attics that hit 130 degrees in August. When we install, we switch to the aluminum-based CertainTeed ridge vent options where the homeowner will approve the modest upgrade, because the trade-off in longevity is worth it here.
• Flashing failures at valley intersections common to all CertainTeed lines. This is more about the installer than the brand, but we see it on CertainTeed roofs at a predictable rate. Valley flashing that was pieced together or nailed too tight eventually pulls and leaks. On every CertainTeed installation we do, valleys get a continuous or properly lapped flashing treatment, not a patch job.

Our CertainTeed Roof Installation Process

Here’s exactly what a CertainTeed roof installation looks like when you hire us. No mystery steps, no crew you don’t know showing up.

1. 1
   Call and written estimate. You call (341) 217-2677. We schedule a visit. Grant or a senior tech walks the roof, checks the decking where accessible, and writes up a line-item price. That price is yours before you commit to anything.
2. 2
   You know who’s coming. After you approve the work, we send the installation lead’s name and photo. On the first morning, he badges in with photo ID at your door. Every tech on your roof is background-checked and in a clean Mercer uniform.
3. 3
   Tear-off and decking inspection. We pull the old shingles, inspect the decking, and replace any rotted or delaminated sheathing. This is where we find the stuff the original installer papered over, and it’s priced per-sheet at a number you already agreed to in writing.
4. 4
   Underlayment and flashing. We install high-temperature rated underlayment across the entire deck, new flashing at every penetration and valley, and drip edge where it belongs. This is the part you’ll never see but will absolutely matter in July.
5. 5
   CertainTeed installation. The shingles go on per CertainTeed’s published nail pattern and sealant guidance. Our crew checks nail placement continuously, which most crews don’t, because a high nail on a single shingle shortens the roof’s life by years.
6. 6
   Final inspection, cleanup, and guarantee. We walk the roof, check every ridge and valley, run magnets across the yard to pick up stray nails, and hand you your written guarantee. The 365-Day Done Right Promise is included with the job, not an upsell.

What CertainTeed Roof Installation Costs in Woodland Hills

Real numbers, not ballpark vagueness. Here’s what we typically quote in Woodland Hills for a full CertainTeed installation.

Your specific number moves based on roof pitch, square footage, decking condition, and whether you have a single story or two. A steep hillside lot in Woodland Hills adds labor cost. A flat lot with a simple gable roof brings it down. Call (341) 217-2677 for a free, written estimate with your actual number.
