High-Performance Synthetic Underlayment Designed for Durability, Traction

CertainTeed offers RoofRunner, a high-performance synthetic roofing underlayment, bringing additional versatility to CertainTeed’s roofing product line. At just 23 pounds per 250-foot roll, RoofRunner is easy to handle, according to the company, with a high-traction surface designed for wet or dry walkability.

According to the manufacturer, RoofRunner is very durable and water resistant. The product features 90-day UV exposure and resists tearing caused by stretching, high winds and foot traffic. The underlayment is designed to firmly grip 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, notes the company. 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
