Lomanco DeckAir® Shingle Over Roof Intake Vent - 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, as all Lomanco vents, provides maximum ventilation capacity balanced with maximum weather protection. - This is known as the Lomanco Balance.

The Deck-Air®, when properly installed with proper exhaust vents, provides a balanced ventilation system to rid your attic space of trapped heat and moisture.

The DA-4 is an excellent solution for roofs with little or no overhang for the installation of traditional intake vents. Installing the Lomanco Deck-Air® can also boost an insufficient intake system to help you achieve a balanced ventilation system.
