Drawing on a career that began in the early 1970s, he has developed extensive expertise in building envelope engineering, with a focus on roofing, waterproofing, and exterior wall systems. His work involves diagnosing failures in commercial, industrial, and institutional structures, particularly those related to water intrusion, wind damage, and deficiencies in design, materials, or workmanship. He applies detailed inspection and testing methods, including infrared thermography and hydrothermal analysis, to evaluate performance and identify root causes of system failures. He has also held engineering, consulting, and construction roles including Professional Engineer, Registered Building Envelope Consultant, Registered Roof Consultant, Registered Waterproofing Consultant, Registered Exterior Wall Consultant, Certified Construction Specifier, Certified Craft Instructor, and owner of an engineering consulting practice focused on roofing, waterproofing, and building envelope systems.

From early hands-on experience in roofing construction to leading his own engineering consulting practice, he brings a combination of field knowledge and technical analysis to building envelope issues. He has provided expert witness services for more than 15 years, contributing to cases involving construction defects, roofing failures, and property damage, with experience in depositions, arbitration, and trial proceedings. His work has additionally involved evaluation of wind uplift performance, roof drainage systems, air barriers, membrane integrity testing, roof asset management, electronic leak detection, and construction-related failures involving roofing and exterior wall assemblies.

His qualifications include licensure as a Professional Engineer and multiple advanced certifications in roofing, waterproofing, and exterior wall consulting, reflecting specialized knowledge of building envelope systems and industry standards. He has further maintained leadership and membership involvement with organizations including ASTM International, RCI, Inc. (Roof Consultants Institute), the Construction Specifications Institute, the National Roofing Contractors Association (NRCA), the Air Barrier Association of America, and the American Society of Civil Engineers (ASCE), including participation on examination committees, educational seminars, and technical presentations related to roofing, waterproofing, and building envelope performance.
