The color on this roof
The work order lists the color as Quarry Gray. That name isn’t in our Owens Corning TruDefinition Duration color gallery, so we’re not showing a swatch that might be the wrong one. The image above is the shingle line itself. Your project manager can bring a full-size sample of any color out to your house. You can also browse every OC Duration color here.
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. 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.
- 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 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. Continuous exhaust at the peak. Together with the soffit intake, it moves heat and moisture out of the attic.
