The roofing system on this house
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. Every one of our replacements is a system, not just shingles. On this roof, from the deck up:
- 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.
- 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 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 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.
