Mark S. Graham holds a Bachelor of Science degree in Architectural Engineering from the Milwaukee School of Engineering. In 1984, he began his career in the roofing industry when he joined F.J.A. Christiansen Roofing Co. Inc. in Milwaukee as an estimator and project manager. In 1986, he joined Wiss, Janney, Elstner Associates Inc., in Northbrook, Ill., as a project engineer specializing in the investigation, design and repair of roof and waterproofing systems.
Graham joined NRCA in 1993 and is responsible for the association's Technical Services Section. Responsibilities of this section include response to inquiries for technical information and assistance, serving as the association's technical liaison with outside organizations, and developing and maintaining the association's technical documents, including The NRCA Roofing and Waterproofing Manual. Graham is the staff liaison to NRCA's Technical Operations Committee and Manual Update Committee. He also is contributing editor for
Professional Roofing magazine.
Graham is a member of the American Society for Testing and Materials (ASTM) and is active in ASTM Committees D-8—Roofing and Waterproofing, C-16—Thermal Insulation, E-5—Fire Standards, and E-6—Performance of Buildings. He also is a member of the American Society of Heating, Refrigerating and Air-Conditioning Engineers Inc., International Code Council and National Fire Protection Association.
