About the presenter:

As a founding member of BCBEC and its’ first president in 1988 John Wells has been responsible for the dissemination of a considerable amount of knowledge in the building envelope field, not only in the Lower Mainland and BC but across Canada and the US. Mr Wells has contributed a great deal to the development of roofing practices through his involvement with the Roofing Contractors Association of BC (RCABC). John has been in private practice for the last 16 years and is currently the senior partner and president of Wells Klein Consulting Group Inc. As a roofing consultant, Mr. Wells has specified, designed and reviewed a wide range of roofing systems on the Island and Lower Mainland of BC. His experience in analysing past roofing failures and understanding their root cause has been invaluable in helping to prevent future roof tragedies. His energetic and humorous presentation is guaranteed to get the message across.

About the Topic:

This is a look at the investigative process following the failure of a new single ply roof membrane on an up-market condominium building. The failure led to a number of major damage claims to the insurance company and a requirement for a replacement roof after less than 6 months of service. The initial failure on the surface appeared to be wind related but a more complete analysis proved that components of the roof had failed prior to the wind event. The investigation pointed out fundamental problems with the roof and building envelope design, all of which were exacerbated by poor workmanship and the poor application of “value engineering” which was a contributing factor in the demise of the roof.

The presentation will lead us through the investigative process with sketches and photographs. The audience will be invited to take part in an interactive forensic analysis from which the failure mode conclusions are drawn. The intent of the presentation is to show how even proper building processes can go astray when driven by misplaced “value engineering” in conjunction with inexperience and poor workmanship and how they can be avoided in the future.
