What went on this roof
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.
- 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 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. It runs along the peak and lets hot, damp attic air escape. That protects the decking and keeps shingles from baking from below.
