Use of Snow Retention Devices: Science or Science Fiction? Phacts or Phobias?

Wednesday, February 14th from 9:15-10:15 AM


This session offers a step-by-step commonsense approach to understanding how snow acts on roofs, debunking misconceptions. Match the snow-retention system to the project by using science and math, not guesswork and supposition. Logical concepts and easy-to-follow instructions will promote better understanding of how to control snow and ice on rooftops with manufactured products. Haddock has traveled the globe researching northern roof design, snow effects, and snow-retention systems and written technical articles and industry-standards documents on the subject. Using his 10 years observing proper and improper application of snow-retention devices, Martin will discuss examples of common mistakes and best practices.
