How Owens Corning Products Fail – and How We Fix Them

Owens Corning makes a good shingle. But San Diego’s combination of relentless UV, salt air near the coast, and Santa Ana wind cycles stresses every manufacturer’s product in predictable ways. Here’s what we see most often on Owens Corning roofs across San Diego, and what we do about it.

• Duration Series granule loss on south-facing slopes. Duration shingles carry a thick granule layer, but after 12 to 15 years of direct San Diego sun, south and west exposures start shedding granules into the gutters. The asphalt below oxidizes and the shingle gets brittle. We catch this on inspections before it leaks, then replace the affected slopes with the closest matching current-production Owens Corning color rather than spot-patching, which always shows.
• Oakridge seal strip failures after heat cycling. Older Oakridge shingles relied on a thermal seal strip that can release after years of hot-day expansion and cool-night contraction, especially on roofs with poor attic ventilation. Wind then lifts the shingle tabs. The fix is either re-sealing with a manufacturer-compatible adhesive where the shingle still has life, or a slope replacement where it doesn’t. Tabs that flip back and forth in a breeze are the tell, and they never fix themselves.
• Nail-line issues on SureNail strips that were never engaged. Duration’s SureNail strip is a genuine improvement, but only if the installer hit it. We routinely find Owens Corning roofs in San Diego where nails landed high or low of the reinforcement zone, which voids the wind warranty and leaves the roof vulnerable exactly where it shouldn’t be. A nail-pop inspection tells us a lot about how the whole roof was installed, and we adjust our repair scope accordingly.
• Valley and flashing leaks where Owens Corning shingles meet old metal. The shingles are rarely the leak source themselves. It’s usually the valley metal, pipe boot, or sidewall flashing that gave out first, and water finds the seam. We replace the failed flashing and any damaged shingles around it as a unit, which is the only repair that lasts. Patching shingles over a failed valley just moves the leak downstream.
• Ventilation-related curling on homes without ridge venting. Owens Corning shingles respond badly when attic heat has nowhere to go. We see deep curling and lifting tabs on San Diego homes with original low-profile vents or none at all. The correct fix includes addressing the ventilation, not just the shingle, otherwise the replacement will curl on the same schedule. We’ll explain this in plain language before any work starts so there are no surprises.

Our Owens Corning Roofing Company Process

Every Owens Corning job we run in San Diego follows the same sequence, whether it’s a two-hour repair or a full replacement. It’s built around the Kingswell Way: say the price before the work, show up in the window we gave, leave the place cleaner than we found it, put the guarantee in writing.

1. 1
   Call and diagnosis. You call (619) 393-3877, a live person answers, and we schedule a visit in a specific window. On arrival we inspect the roof, the attic, and the gutters to find the actual source, not just the stain on the ceiling.
2. 2
   Written price, no ladder touched. Before any work begins, you get a written line-item price. No verbal ballpark that changes at the door, no “we’ll see what we find” escalation. This is non-negotiable for us.
3. 3
   Parts decision, explained to you. We tell you exactly what we’re using and why. On Owens Corning work, that means matching the existing shingle line and color closely, using manufacturer-compatible accessories where it matters, and flagging anything that doesn’t meet Owens Corning’s install spec.
4. 4
   The work itself. Uniformed, background-checked technicians do the repair or replacement, protect your landscaping, and keep the site orderly. We pull permits on full replacements because San Diego building code requires it, and inspections give you a second set of eyes for free.
5. 5
   Test and walkthrough. We water-test repairs where practical, walk the roof with you afterward, and hand you the written guarantee before the crew leaves. Not mailed later. In your hand.
6. 6
   365-Day Done Right Promise. If anything we touched fails inside a year, we come back and make it right at no charge. That’s the whole promise. One year, documented, in writing.

Why San Diego Homeowners Call Tilehurst Roofing San Diego for Owens Corning Work

Plenty of roofing companies in San Diego will tell you they can work on Owens Corning. The difference is what happens when the work is done. We’re a Kingswell family company, founded in 2000, and we operate under a guarantee structure that’s written down, not implied. Every repair gets a written guarantee before the crew leaves. If a repair fails inside the guarantee period, we return at no charge under our 365-Day Done Right Promise. A live person answers our phones 24 hours a day, seven days a week, and that includes evenings and weekends. When we show up, the technicians are background-checked and in uniform. And because we install materials from seven manufacturers including GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, we’re never trying to force one brand onto your roof. Greg Holloway grew up in Los Angeles, learned roofing in a construction trades program at Los Angeles Trade-Technical College, and has spent years putting roofs on San Diego homes from bungalows near Balboa Park to larger properties out in Santee. He still insists on a written price before anyone touches a ladder.
