Materials installed, layer by layer
The feature that defines Owens Corning Duration is SureNail Technology, a tough woven fabric band in the nailing zone that the fasteners go through for better hold. Every one of our replacements is a system, not just shingles. On this roof, from the deck up:
- Synthetic underlayment over the whole deck. It’s stronger and more tear-resistant than felt, and it lies flat if weather rolls in during the tear-off.
- Self-sealing ice and water membrane where water concentrates. It seals around every nail driven through it, which matters in valleys and at the eaves.
- GAF Starter strip along every edge. The first course is where wind gets under a roof. A factory starter with its own sealant line locks it down.
- Owens Corning Hip & Ridge on the hips and peak. Matching cap shingles made for the job, not field shingles cut into pieces.
- Lomanco Omni Roll ridge vent. Continuous exhaust at the peak. Together with the soffit intake, it moves heat and moisture out of the attic.
