Materials installed, layer by layer
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:
- Synthetic underlayment over the whole deck. It’s stronger and more tear-resistant than felt, and it lies flat if weather rolls in during the tear-off.
- Ice and water membrane at the eaves and in the valleys. This self-adhering layer goes where water backs up: behind ice dams at the eaves and where two slopes meet.
- 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.

Questions homeowners ask about this project
What shingle was installed on this Imperial roof?
Owens Corning OC Duration, over synthetic underlayment across the full deck. The full system is in the project details table above.
How big was the roof on Hermitage Drive?
64.00 squares, or about 6,400 square feet of roof surface. A roofing square is 100 square feet. Roofs are measured and priced that way, not by the square footage of the floor plan.
How long did this project take from start to finish?
371 days from the day the job was opened to the day the crew finished. Most of that time is scheduling, material ordering and any insurance paperwork. The tear-off and install usually take a day or two on a house this size.
Was ice and water shield installed?
Yes. Alco Ice & Water membrane went in the valleys and along the eaves, the spots where water backs up or collects first.
