R-Vent® is a roof ventilation mat designed to create an airspace to promote multi-directional air flow between the roofing material and the sheathing below. R-Vent® prolongs the life of the roof structure and membrane by reducing the adverse effects associated with water damage including mold, mildew, or corrosion and deterioration of the roofing material itself. R-Vent® is perfect for residential and commercial applications.

Benefits

  • Creates an open structure for heat reduction and ventilation.
  • Reduces moisture’s ability to remain trapped between the sheathing and underside of the metal roof panel.
  • Prolongs the life of the roofing membrane & sheathing.
  • Reduces sound transmission through the metal panels.
  • Lightweight & easy to install.
  • Bends and conforms to any type of contoured surface.
  • Maintains thermal break.
  • UV exposure of 60 days.
  • Manufactured from Nylon 6.
  • 25-year warranty.

Install plywood roof sheathing onto rafters. Install roofing felt or ice dam protection membrane over sheathing. Check local codes and manufacturer’s recommendations for specific requirements.

Install R-Vent® over roofing felt, ice protection membrane, and metal edge flashing or drip edge. Ensure R-Vent® material is installed flush against edge of the flashing or drip edge. Carefully trim the R-Vent® material at all penetrations with a utility knife or scissors.

When installing metal or alternate material shingles, unroll R-Vent® horizontally just ahead of the shingles as they are installed. Tack or nail R-Vent® in place every three square feet. Do not overlap the R-Vent® material. Butt each course tightly against the previous course and at vertical seams.

When installing vertical metal roofing panels, unroll R-Vent® vertically from ridge to eave just ahead of the metal panels as they are installed. Tack or nail R-Vent® in place every three square feet. Do not overlap the R-Vent® material. Butt each course tightly against the previous course and at vertical seams.

At ridge locations, extend R-Vent® material over the ridge and butt against the material on the opposite side of the roof. If a ridge vent is utilized, follow the ridge vent manufacturer’s recommendations for underlayment material installation.

Apply roofing materials using manufacturer’s recommended fasteners and instructions, allowing for the additional thickness of the R-Vent® material.
