MISSISSAUGA, Ontario — CertainTeed® announced the addition of RoofRunner® AIR to its line of innovative roofing products to the Canadian market. RoofRunner AIR is a breathable synthetic roof underlayment with a multilayer coated structure that promotes rapid roof deck drying. 

Created with both contractors and homeowners in mind, RoofRunner AIR was designed with unique permeable layers that allow moisture to pass through to help prevent mold, rot, and structural damage overtime. The product is made for use on roof decks as a water-resistant layer beneath asphalt roofing shingles, helping to maintain a dry and healthy roof deck. In comparison to other offerings in the marketplace, RoofRunner AIR has a flexible grip to the deck, helping to reduce the chance for fastener pulls as installers maneuver on the roof during shingle installation. 

“At CertainTeed, we are passionate in developing innovative solutions that contribute to the overall durability and sustainability of a home,” said Julie Short, market manager at CertainTeed. “When combined with proper attic ventilation, breathable underlayments like RoofRunner AIR can aid the longevity and integrity of the roofing system. CertainTeed’s industry-leading portfolio of roofing products allow peace of mind for both the contractor and homeowner.” 

Contractors are able to easily and safely install a full CertainTeed roofing system that meets code specification requirements. This breathable underlayment has four layers for optimal durability, but is still a lighter weight synthetic at 35 pounds (16 kilograms) per roll. RoofRunner AIR is backed by a limited lifetime warranty. 

RoofRunner AIR is currently available in all Canadian provinces. Check with your local distributor for availability. For more information about CertainTeed’s RoofRunner AIR offering, visit certainteed.com/residential-roofing/products/roofrunner-air/.
