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. The shingle is only the top layer. Here’s the full system that went on this house:
- A full layer of synthetic underlayment. It’s the backup water barrier under the shingles, and it holds up to foot traffic and wind far better than paper felt.
- Ice and water membrane at the eaves and in the valleys. This self-adhering layer goes where water backs up: behind ice dams at the eaves and where two slopes meet.
- Factory 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 cap. Pre-formed cap that seals the hips and ridge.
- Lomanco Omni Roll ridge vent. Continuous exhaust at the peak. Together with the soffit intake, it moves heat and moisture out of the attic.
