Lomanco OW-4 Omni-Wall Shingle Over Wall Vent, Black, 4 ft Section
The Lomanco OW-4 Omni-Wall Shingle Over Vent provides functional ventilation where a roof joins a wall and can also be used on contemporary shed (mono-slope/single-slope) roofs. This black 4-foot section shingles over for a weather-tight appearance. It pairs with standard shingle roofing and other Lomanco ventilation components.
Key Features:
- Wall-roof ventilation: Provides functional ventilation where the roof joins a wall.
- Shed roof capable: Also suitable for contemporary shed (mono-slope/single-slope) roof applications.
- Omni baffles: External perpendicular omni baffles manage airflow and help block weather intrusion.
- Weather-proof joint: Weather-proof under lapping joint keeps water out at the wall transition.
- Shingle over: Shingle-over design blends into the finished roofline.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
Wall vents like the OW-4 solve intake ventilation on roofs where a conventional soffit does not exist, such as saltbox or shed roof designs. Keep the run continuous along the wall junction for balanced airflow, and shingle carefully over the lapping joint to preserve its weather-proofing. Confirm net free area against your overall attic ventilation calculation before ordering.
Maintain attic ventilation in line with local building codes, and flash and shingle over the vent carefully to prevent leaks at the wall junction.
Order the Lomanco OW-4 Omni-Wall Vent for ventilation where your roof meets a wall.
