Forensic testing is playing an increasingly larger role in determining the cause of building exterior failures. The most important attribute of properly completed forensics testing is that it eliminates subjective thought and presents objective analysis based on factual evidence. This type of testing can also be utilized to provide critical information about existing roof systems and aid in establishing a program to extend the service life. In roofing and waterproofing investigations, forensics testing can be employed through two investigative methods: on-site analysis or material testing in an off-site laboratory. This webinar will explain how these methods can be conducted at all roofing and waterproofing components.
