The Asphalt Roofing Manufacturers Association (ARMA) has partnered with ASTM International to develop Product Category Rules (PCR) for asphalt roofing in North America.
While four out of five homeowners choose asphalt roofing over other materials, there are many factors that contribute to this important investment decision.
In total, 59 asphalt roofing manufacturing facilities in North America were recognized for their outstanding safety records in the manufacture of asphalt roofing materials.
