Erby Posted January 10, 2017 Report Share Posted January 10, 2017 Peeled that membrane right off the roof! Quote Link to comment Share on other sites More sharing options...
Nolan Kienitz Posted January 10, 2017 Report Share Posted January 10, 2017 Erby's comment was far more "scientific". I would say the "blankie" got blown off the bed. Quote Link to comment Share on other sites More sharing options...
kurt Posted January 12, 2017 Report Share Posted January 12, 2017 Definitely wild. What I've witnessed is high winds running over a roof create lift as an airplane wing does. They start to lift, then "bounce flap" up and down, and then it's WHAM. Wind force increases exponentially with velocity. The break point is around 50mph, or so it feels; it's really hard to stand in a 50mph wind. At 65mph, the curve goes steep. 70mph, you're getting blown off your feet, you can't stand up. Put that on 5000sf of anything and it's a lot of force. Quote Link to comment Share on other sites More sharing options...
Rob Amaral Posted January 13, 2017 Report Share Posted January 13, 2017 I've seen some interesting membrane-roof 'lift-damage' on buildings on the Boston waterfront.. Quote Link to comment Share on other sites More sharing options...
