Since its incorporation in 1981, Henry Company has grown beyond its roots in Southern California into a national supplier of air and vapor barrier, roofing and waterproofing products. In 1998, Henry Company expanded through the acquisition of Monsey Bakor Inc., a leading manufacturer of roof coatings, cements and driveway maintenance products. The acquisition extended Henry's reach across all of North America, making Henry one of the largest North American manufacturers of roof coatings and cements.
