On North Sappington Road in St. Louis, MO (the Kirkwood and Des Peres area), the crew tore off and replaced a 21.00-square roof, right around the size of a typical single-story ranch. It was one of 24 roof replacements our crews completed in St. Louis in July 2026. The system: synthetic underlayment across the full deck, ice and water membrane in the valleys and at the eaves, and OC Duration in Pacific Wave on top.

The color on this roof
The work order lists the color as Pacific Wave. 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.
Materials installed, layer by layer
Duration is Owens Corning's best-known architectural shingle. The engineered, woven SureNail strip across the nailing line is what sets it apart: it gives nails a defined target and grip. 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:
- A full layer of synthetic underlayment. It’s the backup water barrier under the shingles, and it holds up to foot traffic and wind far better than paper felt.
- 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 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.
