Roof 2 Wall Installation Step 4

Step 4: Cap or cover Roof-2-Wall assembly with shingle tabs or heavy-gauge/decorative metal cap. Be sure to caulk all ends and joints to ensure a water-tight installation.

A minimum 3/12 roof pitch is required for Roof-2-Wall application

NOTE: Installer is responsible for sealing ends of vent for each specific application.

Due to the wide variety of material choices and possible installation options, it is the installer’s responsibility to seal the vent assembly’s ends with appropriate method and materials to prevent weather infiltration.
* Be sure to use nails long enough to penetrate vent and roof deck. Heavyweight, architectural and re-roof installations may require a longer nail than the 2 1/2" ones provided.

Buildings wider than about 30 feet from the edge of the outside wall to the junction of the roof and wall are usually too wide to use the Roof-2-Wall vent with. Our ridge vents were designed for residential and light commercial use. Our vents will not vent enough air to meet code requirements on buildings over 30 feet wide between the outside wall and the roof to wall junction. Please call Cor-A-Vent before using the Roof-2-Wall vent on buildings wider than 30 feet between the outside wall and the roof to wall junction.
