What went on this roof
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. People shop for the shingle, but what’s underneath it and how the edges are finished decide how long the roof lasts. On this job:
- 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.
- OC 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.
- OC ProEdge 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. Continuous exhaust at the peak. Together with the soffit intake, it moves heat and moisture out of the attic.
