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.
- Ice and water shield in the valleys and along the eaves. Those are the two places a Midwest roof takes on water first, from ice dams in January and heavy runoff in spring storms.
- 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 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.
