RoofRunner™ is a new high performance synthetic roofing underlayment, bringing additional versatility to CertainTeed’s roofing product line. At just 23 lbs. per 250-foot roll, RoofRunner is easy to handle, with a high traction surface designed for wet or dry walkability. Very durable and water resistant, RoofRunner features 90-day UV exposure and resists tearing caused by stretching, high winds and foot traffic.  

RoofRunner firmly grips to the roof deck, providing a stable surface for builders and reducing pulling against mechanical fasteners. Its light gray surface offers a cool working environment, so those working on roofs all day have fewer worries about overheating.  

RoofRunner exceeds the performance requirements of ASTM D226 and D4869, it conforms to UL 790/ASTM E108 for Class A fire resistance, is Florida Product Control Approved, and also conforms to the ICC-ES AC188 standard. RoofRunner qualifies as a component in CertainTeed’s Integrity Roof System. 

RoofRunner is now available throughout the U.S. and Canada. For more information, visit
