What went on this roof
Owens Corning Supreme is a traditional three-tab shingle, a flat, uniform look that suits smaller sections, outbuildings and homes that were originally built with three-tab. Every one of our replacements is a system, not just shingles. On this roof, from the deck up:
- 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.
- 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.
