Materials installed, layer by layer
Owens Corning TruDefinition Duration uses SureNail Technology, a woven strip across the nailing zone that gives the fasteners something to grab and helps the shingle stay down in high wind. The shingle is only the top layer. Here’s the full system that went on this house:
- Synthetic underlayment, edge to edge. It doesn’t wrinkle or tear like felt, and it keeps the deck dry if a shower pops up mid-job.
- 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.
