On Barkman Drive in St. Louis, MO (west St. Louis County near Maryland Heights, a few minutes from our headquarters), the crew tore off and replaced a 24.67-square roof, the size of a larger ranch or a modest two-story. It was one of 27 roof replacements our crews completed in St. Louis in September 2026. The system: two layers of synthetic underlayment, a heavier spec than our standard single layer, ice and water membrane in the valleys and at the eaves, and OC Duration on top.

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. 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:
- Two layers of synthetic underlayment. That’s double our standard spec. The second layer adds another barrier under the shingles.
- 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.
- 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 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.
