Commercial Roofing Issues - Beyond the Webinar

Host Rich Grimshaw joins Chris Scallion and Matt Hodge for this week’s aftershow exploring three unique commercial roofing case studies. Chris starts with a study that shows even an average summer rainfall and thunderstorm system can be disastrous for a commercial roof with a host of other bad conditions.  Matt’s first study looks at a roof that appeared to “blowing away” even though there were no wind events – it turns out that the underlying problem could be traced back to school lunch. And finally, we end with the “Cadillac” of roof systems that uplifts after just a few months.
