How CertainTeed Products Fail – and How We Fix Them

CertainTeed makes a solid shingle. We install them, and we also replace them when they’ve done their time. Here’s what we actually see on Los Angeles roofs, line by line.

• Landmark shingle granule loss on south-facing slopes. The Landmark series is CertainTeed’s most popular architectural shingle in Los Angeles, and it holds up well, but on south-facing exposures in neighborhoods like Woodland Hills and Sherman Oaks, we see premature granule shedding after 12 to 15 years. The cause is sustained UV loading plus the thermal shock of cool marine-layer mornings followed by 90-degree afternoons. Once granule loss exposes the asphalt mat, replacement is the only real fix. We tear off to the deck, check for dry rot, and re-roof with a fresh underlayment system.
• Presidential Shake cupping and curling at the eaves. The Presidential Shake is a thick, high-end laminated shingle that mimics cedar shakes. On Los Angeles homes with inadequate attic ventilation, we find the eaves curling upward within 10 years. The shingle traps heat differently than a standard architectural, and if the attic can’t breathe, the shingle bakes from underneath. Our fix starts with ventilation correction, then a full replacement using the same Presidential Shake line, properly ventilated this time.
• Integrity 18 delamination after wind events in the foothills. Homes up in Tujunga, La Crescenta, and the base of the San Gabriels take real wind. The Integrity 18 is a three-tab shingle with a plastic nailing strip, and we’ve seen the adhesive strip separate from the mat after repeated gusts over 40 mph. Once shingles start flapping, the roof is compromised. We replace with an architectural line like Landmark or Northgate, which carries far better wind performance for the same or similar cost.
• Water intrusion at pipe flashings on all CertainTeed lines. This isn’t a shingle failure, it’s a flashing failure, but it’s the most common leak we trace on CertainTeed roofs in Los Angeles. The neoprene boot around plumbing stacks dries out in our low-humidity climate and cracks within 8 to 10 years. If caught early, it’s a repair. If water has been running under the shingles for a season or two, the decking rots and you’re into partial or full replacement. We check every penetration during a replacement and install new lead or high-grade synthetic boots.
• Low-slope sections with Flintlastic SA blistering. Many Los Angeles homes built between the 1940s and 1980s have flat or low-slope sections, often over add-ons or carports. CertainTeed’s Flintlastic SA self-adhered cap sheet works well on these sections when installed properly, but if the original installer didn’t prime the substrate or rolled it on a cold morning, blisters form within a few seasons. We remove the blistered membrane, repair or replace the substrate, and reinstall to spec, then integrate the section with the new shingled field.

Our CertainTeed Roof Replacement Process

Here’s how a CertainTeed replacement works when you hire us, step by step.

1. 1
   The call. You reach a live person at (213) 674-2890, any hour, any day. We hear what’s going on and schedule an inspection.
2. 2
   The roof inspection. We walk the roof, check the decking from the attic, note the current underlayment, flashing, and ventilation. We identify exactly which CertainTeed product is up there and how it performed.
3. 3
   The written price. You get a line-item written estimate before any work starts. It includes material choice from all seven manufacturers we work with: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. No price changes at the door.
4. 4
   The tear-off and deck inspection. We remove the old shingles down to the decking and inspect every sheet. We’ll tell you, in person and with photos, if sheathing needs replacement before we cover it up.
5. 5
   Installation. Proper underlayment, new drip edge, proper nailing pattern per CertainTeed’s installation spec, new flashing, ridge cap, and ventilation if required. Background-checked, uniformed technicians do the work.
6. 6
   The walkthrough. We clean up, walk the roof with you, and put the guarantee in writing. Our 365-Day Done Right Promise means if anything isn’t right within a full year, we come back and fix it at no charge.
