Shed roof ridge vent.
Lomanco omni series ridge vents are available in two versions and two styles.
A ridge vent is installed at the peak of the shed roof for shed ventilation.

Integrity roofing and painting.
Shingle up to the area that requires the smartvent roof to wall vent application.
Ensure there is proper continuous intake ventilation below proposed roof to wall ventilation.
The regular omni style is traditionally installed using a hammer while the lo omni style with its low profile can be installed using a nail gun.
For existing roofs remove the ridge shingles and cut back the sheathing about 1 3 on either side of the peak.
The roll versions comes in easy to handle 20 and 30 foot lengths while the stick version comes in 4 foot lengths.
