The roofing system on this house
Supreme is Owens Corning's three-tab shingle: a flat, even pattern that matches older three-tab roofs and works well on garages and small sections. The shingle is only the top layer. Here’s the full system that went on this house:
- Two layers of synthetic underlayment. That’s double our standard spec. The second layer adds another barrier under the shingles.
- Self-sealing ice and water membrane where water concentrates. It seals around every nail driven through it, which matters in valleys and at the eaves.
- 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 on the hips and peak. Matching cap shingles made for the job, not field shingles cut into pieces.
- 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.

What shingle was installed on this St. Louis roof?
Owens Corning OC Supreme, over two layers of synthetic underlayment, a heavier spec than our standard single layer. The full system is in the project details table above.
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.
How big was the roof on Larkin Lane?
32.00 squares, or about 3,200 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?
70 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.
