The roofing system on this house
Supreme is Owens Corning's three-tab shingle: a flat, even pattern that matches older three-tab roofs and works well on garages and small sections. The shingle is only the top layer. Here’s the full system that went on this house:
- Synthetic underlayment, edge to edge. It doesn’t wrinkle or tear like felt, and it keeps the deck dry if a shower pops up mid-job.
- 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 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.
- OC ProEdge Hip & Ridge cap. Pre-formed cap that seals the hips and ridge.
- 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.
