Looks like my CHI insulated double panel 14'wx9't is starting to buckle at the bottom corners. I'm thinking this is from having the rails at an angle matching my roof pitch. And with the Liftmaster 8500 opener putting load on the pins while opening and sitting at the angle when open.
Anyone else seen this and what do I do to reinforce the door?
I know the picture doesn't show it well but you can see the way the seal is deformed.
