How Owens Corning Products Fail – and How We Fix Them

Owens Corning makes solid roofing materials, but every product line has its weak points, and Orange County’s specific climate exposes them faster than most. Here’s what we actually see on roofs across the county.

• Duration Series granule loss on south-facing slopes. The Duration line, especially Duration Designer and Duration Storm, uses thick asphalt and heavy granules. But on Orange County homes with steep south-facing exposure, the constant UV load causes premature granule shedding. You’ll see it as bare patches or excessive grit in gutters within 8 to 12 years. We catch it during inspections and flag it before the underlying mat starts to fail.
• Oakridge series cracking at the sealant strip. Oakridge shingles have a narrower sealant band than Duration. On roofs with poor attic ventilation, heat builds up and the shingles flex. Over time, that sealant strip cracks loose, and shingles start lifting. We’ve repaired this on everything from ranch homes in Yorba Linda to two-story tract houses in Lake Forest. The fix is usually replacing the lifted shingles and correcting the ventilation rather than a full re-roof.
• Supreme (3-tab) curling and blow-off. The Supreme line is Owens Corning’s economy 3-tab shingle. On older Orange County homes, especially those built in the 1980s and 1990s, we see tabs curling at the corners and entire tabs tearing away in Santa Ana wind events. These shingles have a shorter functional life than architectural lines. When we see 3-tab curling on more than 20% of the roof, we tell the homeowner plainly: repair will get you a year or two, but replacement is the honest call.
• VentSure ridge vent compression on low-slope sections. Owens Corning’s VentSure ridge vents work well when installed correctly. But on Orange County homes with low-slope sections or valleys near the ridge, we find vents that were nailed too tight, compressing the filter fabric and blocking airflow. The attic overheats, and the shingles above cook from below. We re-install the vent with proper fastening and spacing, and the temperature differential drops immediately.
• Flashing failures at Owens Corning-to-tile transitions. A lot of Orange County homes mix Owens Corning composition shingles with tile accents, especially in newer developments in Irvine and Rancho Santa Margarita. The transition point where the shingle field meets the tile is a classic leak zone. Flashing gets installed with the wrong overlap, or sealant fails after a few seasons of thermal movement. We rebuild those transitions with correct step flashing and proper underlayment overlap.
