Mr. Patterson founded ROOFTECH in 1983 and built ROOFTECH into one of the largest and most respected roof consulting companies in the Southwest. Mr. Patterson has a national reputation as a roofing expert and educator having written three books on roofing: Roof Design and Practice, Wind Uplift Pressures on Low Sloped Roofing, and Roof Drainage, all of which are available through the International Institute of Building Envelope Consultants (www.IIBEC.org). He has also published a number of peer-reviewed papers, which are available on this website. Mr. Patterson has been solving complex roofing problems for more than 40 years. His structural engineering background along with his experience as Director of Engineering/Technical Director for two roofing manufacturers and as General Manager of a roofing contracting company set the stage for the formation of ROOFTECH.
Living in Tornado Alley and the Hail Belt provided some unique experiential opportunities as well. Mr. Patterson was a Civil/Structural Engineering student at Texas Tech University when an F5 tornado struck Downtown Lubbock, Texas and Texas Tech. His professors became world renowned wind experts as the result of studies they performed on buildings like the Great Plains Life Building and others. One of Mr. Patterson’s professors and mentors, Dr. Jim McDonald, would later become one of the peer-reviewers of the first edition of Mr. Patterson’s Wind Uplift Pressures on Low-Slope Roofs. Upon graduation from Texas Tech in 1971, Mr. Patterson began working for a precast prestressed concrete manufacturer where he worked in the structural design and estimation department. On one of Mr. Patterson’s projects, a series of structural double-tee roof panels collapsed during construction. The roofers had inadvertently blocked the drainage and overflow scuppers resulting in an excessive build-up of water on the roof and a roof collapse, which was his first roof collapse investigation. Among ROOFTECH’s earliest projects were several high-profile roof collapses in the 1980s, which began a long history of roof collapse investigations … ultimately culminating with the first edition of Roof Drainage, Mr. Patterson’s drainage design book.
Mr. Patterson brings his unique expertise to his roofing analysis, design, and forensic work. He regularly performs forensic investigations pertaining to construction defects, hail, windstorm damage, and other matters for diverse clients including building owners, attorneys, and insurance carriers. Mr. Patterson also continues to teach, write, and publish technical papers related to roofing as well as working closely with his staff on complex roofing problems.
