Upcoming Events


Single Ply Roofing Membrane Symposium

Thursday, February 8th, 2018
11:30 am - 1:30 pm
180 West Georgia Street, Vancouver

Presented by Hamish Matheson, RRO, TQ, IP from the RCABC and Josh Jensen, AScT, CHI, RRO, RRC

In our rain intense region, we tend to avoid risks and stick to what is familiar when it comes to roofing. As with many building systems, single ply roofing did entail a learning curve which the industry has within the last decade largely overcome. Evidence of this is the level and quality of warranties now offered by single ply roofing manufacturers.

The focus will be on accurate field performance results as to risk management, and the choices involved in single ply roofing membrane systems and how these systems have performed in our rain intensive climate. We will talk about what’s been done right and what’s been done wrong and punches won’t be pulled. The result is a frank discussion about what we’ve learned and what are the strengths and weakness of this approach and what goes into a successful single ply system from a planning and execution standpoint.

Learning objectives include:

  1. Details.
  2. What’s gone wrong, what’s gone right?
  3. Requirements in Technical Specifications.
  4. System Limits: when is it appropriate? when is caution warranted?
  5. Questions and comments from the “peanut gallery” will be encouraged.

Josh Jensen is an RCABC-accepted roof inspector and an RCI Registered Roof Observer (RRO) and Registered Roof Consultant (RRC).

He is regularly asked to provide roofing and waterproofing technical education and support to various industry and professional groups throughout Western Canada and the Pacific Northwest of the United States.

His expertise encompasses roofing and waterproofing systems for any application, including ultra-energyefficient and green roof assemblies. Josh consults on all aspects of investigation, design and construction, as well as systems and integrations design, field quality review, RCABC roof inspection, roofing and cladding shop drawings production, and wind uplift design for roofing systems.

Hamish Matheson is Trade Qualified from ITA (TQ) and a Red Seal Ticketed Roofer, an RCI Registered Roof Observer (RRO), and brings roofing and project management experience from New Zealand, Scotland, North West Territories, Yukon, Alberta and British Columbia.

Hamish provides technical support to the design community through reviewing roof details, assemblies, specifications, inspection reports. His role is to help design authorities interpret and effectively use the RCABC Roofing Practices Standards with the ultimate objective of ensuring good roof design and practices.

Hamish also sits on the CSA Roofing Committee, which is responsible for the testing/research and development of many roofing material and installation standards in Canada. He is also an active member of the Special Interest Group for Dynamic Evaluation of Roofing Systems (SIDGERS).
