Learning Objectives:

  1. Discuss the what, where and why of Very Severe Hail (VSH): macro-market need, geographical implications, system requirements and what this all means to you.
  2. Explain the development of a standard: VSH test methods and approvals process.
  3. Explore system design and roofing success: why history of performance is critical in decision-making.
  4. Predict where VSH will go from here: how to navigate the evolution of the standards and system requirements.

In the U.S., commercial and industrial insurer FM Global introduced the Very Severe Hail (VSH) impact-resistance classification in 2016 and it has since been gaining influence across the country. This classification is pushing the envelope for hail performance and could greatly impact product innovation and roof system designs.

With the implementation of this bold standard, everyone in the value-chain of commercial roofing needs to be equipped to answer seemingly simple questions: what is VSH and how do I choose the right resilient roof system to meet the standard’s requirements?

We will cover VSH classifications, geographical implications, test methods and considerations for choosing roof membranes and system design.
