The Lomanco Deck-Air is a shingle over roof intake vent that installs on the roof deck. This multi-tasking vent provides continuous intake airflow and weather protection that can be installed at the roof edge or off the roof edge as required by your ventilation and construction needs.

The DA-4 has a tapered lo-profile design that provides enhanced weather protection. 2-1/2" ring shank nails are included in each box. The DA-4 has an optional specialty use as an off ridge exhaust. The DA-4 is also made from the same durable, long lasting, field tested material as the Lomanco Omni Series Vents.
