Solving Problems One Roof at a Time William John Associates was founded by Doug Wallace in 1980 in response to a need for a company to provide accurate and unbiased information of a full range of roofing issues. Mr. Wallace and Mr Joel Hammock have over 60 combined years of roofing experience, and incorporate a detailed knowledge of roofing systems and installation procedures that differentiates WJA from other more theoretically oriented companies in the industry.
