    The presentation this year will be:

    Terminal Velocity of Hail and Killing the Golden Goose

    The terminal velocity of hail has been assumed to be speeds calculated by the National Bureau of Standards in Publication #23.  The values listed are theoretical numbers based on fluid dynamic equations.   Jim D. Koontz & Associates, Inc. utilized a vertical wind tunnel to measure actual velocities. Factors such as shape and density of hail were considered.  Other factors include barometric pressure, temperature and humidity.

    A large part of the roofing industry relies upon yearly damage to roofs from wind and hail.  A trend of abuses by various parties, insured’s, contractors, public adjusters; are having an effect on how insurance companies are now insuring properties.   The trend may result in major changes to the roofing industry.

    Learning Objectives:

    • Increase understanding of the true free fall velocity of hail.
    • Increase understanding of the effects shape and density have on the free fall velocity of hail.
    • Open a discussion of the effects of abusive claims on the insurance and roofing industry.

    Speaker: Jim D. Koontz, PE, RRC (JDK)
