VentSure® 4-Foot Strip Heat & Moisture Ridge Vents Installation Instructions | Owens Corning Roofing
Owens Corning

VentSure® 4' Strip Ridge Vents are designed for roofs with slopes of 3/12 to 16/12 pitches. 

Intake at the eave vents should be equal to or exceed that of the ridge vent being installed. VentSure ridge vent is designed for residential applications.


Important Notes

  1. On architectural shingles, roofing cement should be used where the roof vent lower edge meets the laminate shingle to prevent wind-driven rain or snow to blow under the ridge vent.
  2. Before applying vent to architectural shingles on new construction, leave felt long at ridge and fold back under vent or caulk between low areas of shingle and flange of vent, making sure you don’t plug holes.
  3. See instructions for cutting slot.
  4. For structures with different ridge heights, be sure to vent the higher ridge; it is also acceptable to vent lower ridges with dormers.
  5. For best appearance, run VentSure ridge vent from end to end to give the roof a more attractive appearance.
  6. For truss rafters, cut a 1" slot on each side of the ridge starting a minimum of 6" from the rake edge of the roof. For roofs with a center pole, cut a 1 1/2" slot on each side of the ridge starting a minimum of 6" from the rake edge of the roof.

Installation Instructions

Step 1

Using a chalk line, mark out 1" on both sides of the ridge as a guide for cutting a slot in the top of the ridge. See Fig. 1.

Step 2

Cut slot using a circular saw with the blade set at a depth to cut through the wood sheathing only. See Fig. 2.

NOTE: Start the cut 6" from the edge of the roof. Remove the sheathing debris from slot.

Step 3

Center the vent over the opening that has been cut in the ridge, ensuring the vent sits flat on the roof. Also ensure that the interlocking tabs are facing the opposite direction you will be installing the next piece of ridge vent. See Fig. 3.

Step 4

As you install the vents, ensure each vent is snapped together, then nail in place using the nail holes marked on each vent. See Fig. 4.

Step 5

Using a utility knife, cut the final piece to a length long enough so that it is flush with the edge of the roof. Connect making sure that the built-in end caps are exposed and nail in place. See Fig. 5.

NOTE: In most cases, the final piece will not use the interlocking feature.

Step 6

Nail hip and ridge shingle over the vent using nails long enough to meet the penetration requirements of the shingle manufacturer or use nails provided with the VentSure ridge vent. For a clean look, extend the hip and ridge shingle to cover the interlocking tabs or trim tabs off using a utility knife. See Fig. 6.
