Find out what you can learn from roofs and attics that have had problems.

About this event


Taking building investigations and turning them into building science puzzles is fun and informative. In Part II, we learned how to configure high performance attics and roofs. What can we learn from roofs and attics that have had problems? We can learn about tolerances attics and roofs have for heat and moisture management and quite a bit about how to and not to retrofit existing attics and roofs. (webinar recorded February 15, 2019 )


  1. Use building science principles to identify problems in existing roofs and attics
  2. Discuss building science principles to identify solutions in existing roofs and attics
  3. Discuss the uses of building science equipment involved with building investigations
  4. Identify the right questions to ask in your own roof and attic building science puzzles
