About Specifex

Our History

A strong Lineage

Our company grew from a long line of strong players in the roof consulting industry.

Started in 1979 as Inter-Provincial Inspectors (IPI) by Jud Jensen, the company was created due to the need for third party, independent roof application reviews in an industry that was rife with poor and unregulated roofing application tactics.

Shortly after setting up the business, Jud sold the business to Bob Elsdon, who changed the name to Inter-Provincial Inspectors (1982) Ltd. Bob ran and grew the company to become the number one roof consulting company in BC.

In 2005, Bob changed the name of the company to Inter-Provincial Roof Consultants Ltd. to exemplify the broader scope of our services and to more clearly define the “roof” aspect of it. Not only does the company provide inspection services, but advise, information, direction, and leadership to our clients and the industry as a whole.

Bob sold the company to Sean Lang in 2007, when he was ready for retirement. Sean immediately saw the need to upgrade office and field procedures to both improve in-house practices and field practices – and to provide a better and more efficient product to our clients. Gone were the days of hand writing reports and having them typed out by staffers. The computer age was brought in (long overdue, in Sean’s opinion) and the business was streamlined and improved.

After a few years of running the company, and seeing the industry change, Sean decided to change the companies name yet again, to reflect a broader, more holistic scope of our services – hence Specifex Building Science Inc. was created.

Specifex is an amalgam of the words “Specify” (to define clearly and specifically) and “Artifex” (latin for master of an art).

While we still mostly focus on the roofing and waterproofing aspects of a buildings envelope, we pay close attention to all aspects of the building envelope when reviewing, specifying, and observing roof installations.
