Roof Expert Witness – Criteria
June 21st, 2010
As roofing experts we do not know all the answers but know where to go to find answers. A roof expert witness who understands the criteria and standards and how they apply to given situations can be best suited to assist with disputes and problems.
Technology within the roofing industry is well established and there is an abundance of published criteria for roofing systems, their components, and their installation. These are the factors that become the basis for a roof expert’s field analysis, conclusions, and opinions. Based upon the published criteria roof experts can express their findings and opinions within a reasonable degree of certainty and based upon information available at the time of the investigation.
The National Roofing Contractors Association (NRCA) published “The NRCA Roofing and Waterproofing Manual”. The technical data in this manual forms the basis for accepted industry practice. All major roofing material manufacturers publish criteria for performance of their materials as well as proper installation techniques. What many people do not understand is that the published criteria of both the NRCA and the roofing system manufacturers should be considered the minimal standards for application and performance. When these standards are not met, problems can arise.
“ASTM International is one of the largest voluntary standards development organizations in the world-a trusted source for technical standards for materials, products, systems, and services. Known for their high technical quality and market relevancy, ASTM International standards have an important role in the information infrastructure that guides design, manufacturing and trade in the global economy.” ASTM publishes performance standards for all kinds of materials and these standards form the basis upon which materials can be tested.
There are numerous other agencies such as The National Institute of Science and Technology (NIST) which provide published criteria. “Founded in 1901, NIST is a non-regulatory federal agency within the U.S. Department of Commerce. NIST’s mission is to promote U.S. innovation and industrial competitiveness by advancing measurement science, standards, and technology in ways that enhance economic security and improve our quality of life.”
