What went on this roof
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. 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 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.
