I made a pretty dumb mistake on my roof panels, I thought (there's the problem!), that if I left the bottom edge of the panel unsealed it would allow condensation to run down the inside of the panel and out. That would keep it from running down the walls, that is often the way it works with glass, but glass is rigid, the panels are not. I've withstood 40-50 mph wind BUT with gusty conditions the other day it was different.
The gust caused enough pressure difference to cause the bottom edge to puff up allowing another perfectly timed one to catch the lower edge and lift/flex the panel up in the center, pulling it from under the side clips and over the screw head. I have since sealed and added a screw to the bottom of the panels.
I also installed 2 of the Bayliss vent controls which seem to be working fine and are enough to prevent overheating this early in the season. Be careful if you order these prices vary a lot between suppliers.
