Materials installed, layer by layer
Duration is Owens Corning's best-known architectural shingle. The engineered, woven SureNail strip across the nailing line is what sets it apart: it gives nails a defined target and grip. The shingle is only the top layer. Here’s the full system that went on this house:
- 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.
- 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 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.
