Ouch! We had some crazy wind here too! Trampoline survived though :) I tied it down with three of the deals that you attach a dog chain to. Used a electric impact to screw them into the ground and attached the trampoline with small chain and bolts. Even stayed put through our last hurricane!
As for the garage door, take a hammer and dollie to it and smooth out the dents. No need to spend a grand on a new door! I am really surprised the winds didn't blow that type of door out of its tracks. Happened several times at the dealer I worked for. Destroyed them in seconds!
I have the same type rollup door on my shop too. I drilled holes about every two feet on each side and put pins through the track and door to stop it from flexing enough to pull out of the tracks. Just something to think about in the future. Seems the weather is getting more violent these days!!!
