The roofing system on this house
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.
- 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.
- Factory starter at the eaves and rakes. It’s a purpose-made starter strip with factory adhesive, not cut-up field shingles, so the edges stay sealed.
- 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. It runs along the peak and lets hot, damp attic air escape. That protects the decking and keeps shingles from baking from below.
