I am not really that worried about burglars. We are home most of the time and I have a hunting dog strain of Yellow Lab that doesn't miss much. This is Florida. My sheriff encourages us to shoot burglars.
My guess is if someone is breaking in, they probably are not going to start on the roof anyway. They usually go after sliding glass doors. Mine is a little tougher than most with impact glass that makes the doors about 200 pounds each so they aren't just lifting them off the track. There is also blocking above the door that makes that impossible anyway. (code/listing thing)
My real plan for an Egress is a gable end vent that exits over a porch roof. From there we could either get on the roof or into my boat or some other boat that was drifting by. Push comes to shove, I would just kick that out.
