We are an independent Owens Corning service provider, not a manufacturer affiliate, which means our inspection findings are based on what we see on your roof, not on selling you a replacement before it’s time. Most inspections run between $195 and $350 depending on roof size and access, and the price is on paper before we touch a ladder. Call (559) 258-5703 to schedule yours.

How Owens Corning Products Fail – and How We Fix Them

Not every roof fails the same way. Owens Corning shingles have specific patterns we see again and again across Orange County, from Anaheim Hills to Lake Forest to Huntington Beach. Here’s what we actually find when we get up on the roof:

• Duration and Oakridge granule loss along southern exposures. On south-facing slopes in Orange County, UV hits Owens Corning Duration and Oakridge shingles hard for 300-plus days a year. Granule loss starts at the edges first. You’ll see granules in the gutter or a chalky residue on the patio. We check the rate of loss; if it’s advanced, we document photos and give you a repair-or-monitor recommendation. We don’t push a tear-off when spot work will do.
• Duration Series nail strip delamination at the seal line. Duration shingles have a reinforced nail strip, but we regularly see delamination where the seal strip separates from the shingle body, especially on roofs with marginal attic ventilation. High heat cycles the adhesive. We inspect seal integrity on every course, and if we find separation, we reseal or replace the affected shingles using OC-compatible sealant so the manufacturer’s coverage stays intact where it applies.
• VentSure ridge vent uplift in Santa Ana-adjacent corridors. Owens Corning VentSure ridge vents can lift at the edges in high wind zones around the Santa Ana canyons. The symptom is a ridge vent that’s visible from the street or flapping during wind events. We resecure the vent per OC installation specs and check for wind-driven moisture that entered the attic while it was lifted.
• Deck Defense and WeatherLock water peeling at eaves. Owens Corning synthetic underlayments like Deck Defense and WeatherLock hold up well, but on older installs where drip edge was not properly lapped, capillary action pulls water back under the underlayment at the roofline. The tell is dark staining on the fascia board or peeling paint at the eave. We correct the drip edge detail and replace the compromised underlayment section.
• Improper aftermarket flashing replacement from prior repairs. When another roofer replaces pipe boots or step flashing on an Owens Corning roof with generic off-brand parts, the material gauges don’t always match, and we see early corrosion. We inspect every flashing penetration and recommend OC-compatible or equivalent-gauge flashing when replacement is needed.
