How Owens Corning Products Fail – and How We Fix Them

• Duration Series shingle seal failure at the nail line. We see this most often on homes built between 2005 and 2015 in the Stone Oak and Alamo Ranch corridors. Duration’s SureNail strip holds well, but if the original installer drove nails high into the shingle above the strip, the bond never forms at the leading edge. Wind gets under the shingle, dirt builds up, and the shingle lifts. We re-seat and hand-seal the affected courses with a spec-grade asphalt adhesive, and we check the surrounding courses so the same shingle doesn’t fail two months later.
• Oakridge shingle granule loss on south-facing and west-facing slopes. San Antonio’s summer sun works on every shingle, but we regularly find Oakridge losing granules faster on slopes that take direct afternoon heat. The shingle still sheds water, but after enough granule loss the mat starts to dry and crack. We look for granule buildup in the gutters as an early warning. If the mat is intact, we document the wear and advise on a repair timeline. If the mat is cracked, we replace those shingles and match the color as close as the current Owens Corning run allows.
• Pipe boot and vent boot cracking on Supreme and Oakridge installations. The neoprene collar on standard roof pipe boots dries out and splits in about 8 to 12 years under Texas UV. On Owens Corning systems we also see this accelerated when the boot sits near a valley where water concentrates. The leak shows up as a brown ring on the ceiling near the pipe. We pull the old boot, install a new collar, and re-flash it under the surrounding shingles, then seal the top edge so water can’t backdrive into the opening.
• Valley shingle delamination where Duration meets steep pitch transitions. On steeper roofs in Alamo Heights and Olmos Park, valley shingles take more runoff force than the field shingles. We occasionally find the top layer of a Duration shingle separating from its backing at the valley edge because water runs fast through the valley and gets under the lap. We remove the delaminated shingles, inspect the valley metal below, and re-install with proper overlap and sealant. We also check whether the valley was cut too narrow, because that’s often the real culprit.
• Flashing corrosion at chimneys and skylights on any Owens Corning line. This one isn’t a shingle failure, but it’s the most common leak source we trace on Owens Corning roofs in San Antonio. Galvanized step flashing and counterflashing last about 15 to 20 years before the zinc coating wears off and rust takes over. We remove the failed flashing, replace it with new metal cut to fit, and re-bed the shingles above the first course of counterflashing so the lines stay clean. Owens Corning’s installation specs call for two-piece flashing at chimneys, and we follow that even if the original roofer didn’t.

Our Owens Corning Roof Repair Process

1. 1
   Call and describe what you’re seeing. A live person answers 24/7. We’ll ask where the leak is showing up inside the house, how long it’s been there, and what part of the roof faces that wall. Then we schedule a visit that works with your family’s routine.
2. 2
   We arrive and walk the roof before anything moves. Our techs wear shoe covers at the door and lay drop cloths through the hallway. On the roof we photograph everything: the shingles, the flashing, the vent boots, the valley. We look for the cause, not just the symptom.
3. 3
   We explain the repair in plain English and hand you a written price. Before any shingle comes off, you’ll know exactly what we’re doing, which parts we’re using (OEM Owens Corning where it makes sense, quality aftermarket where it doesn’t), and what it will cost. That number doesn’t change unless you ask us to change the scope.
4. 4
   We make the repair and test it. Shingle replacement, flashing replacement, flat roof patch, vent boot swap – whatever the job calls for, we do it clean, then run water over the repaired area to confirm the fix before we come off the roof.
5. 5
   We clean up and show you the proof. Every visit ends with a photo of the completed clean-up. No nails in the driveway, no shingle scraps in the flower bed, no debris left for your dog to find. We show you the photo, then walk you through what we did.
6. 6
   Your 365-Day Done Right Promise starts that day. If the repair isn’t right, Birchbark makes it right. That’s stamped on every job we do, including Owens Corning roof repair.
