Born from a roofer’s 1984 shop-floor solution, AGB Weatherproofing Technologies manufactures the Original Roof Scarfer and other equipment for spray polyurethane foam roofing contractors. Based in Columbia Station, Ohio, the company custom-fabricates its Scarfer with USA-made parts and supports customers with product training, troubleshooting, and hands-on SPF expertise. Its newer Scarfer XR builds on more than 30 years of field use with greater power and durability.
