COR-A-VENT®Roof-2-Wall Vent™ Installation Instructions

One person can easily install the handy four-foot Roof-2-Wall Vent sections. All you need is a hammer, circular saw, chalk line, utility knife, tape measure and a caulking gun. These instructions are typical for a standard shingle roof application. Download the Roof-2-Wall brochure or call our technical department for advice on your specialized application, or send us a print and we’ll “markup” where and how to vent it.

Roof-2-Wall Step 1

Step 1: Start by cutting 1" a wide clear slot in roof deck at or near the top. Stop slot no less than 6" from the ends of the roof section to be ventilated.

Roof-2-Wall Step 2

Step 2: Apply 3/8" bead of polyurethane caulk (provided in box) beneath Roof-2-Wall Vent pieces and nail down with 2½" nails (provided), using a  minimum of three nails per piece. Run vent at least 6" past slot in decking and close off ends by inserting R2W End Plugs (provided) into end openings. Caulk End Plugs to roof and vent and seal ends after placement. Run another 3/8" bead of flexible caulk along the top of all vent pieces.

Roof-2-Wall Step 3

Step 3: Use Roof-2-Wall flashing (provided), or other metal flashing, to cover vent up onto wall. Nail flashing securely to the wall and overlap flashing with house wrap or felt paper/water-proof membrane.

Roof-2-Wall Step 4

Step 4: Cap or cover Roof-2-Wall assembly with shingle tabs or heavy gauge/decorative metal cap – cap should overhang the vent by a minimum of ½". 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

Sealing ends of ventNOTE: 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.

* The provided tube of caulk should be sufficient for installation, but if more caulk is required, use a flexible silicone or polyurethane – DO NOT USE ROOF CEMENT.

Buildings wider than about 20 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 20 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 20 feet between the outside wall and the roof to wall junction.
