Would my truck be damaged in this situation?

I have a 2014 f150 stx with a level kit and 20 inch terra grappler tires on it. I recently had to store the truck in a garage due to a storm passing through. When I pulled the truck into the garage the antenna was bending because it was hitting the ceiling. The top of the truck wasn't hitting the top of the garage but in another 2 or 3 inches the top of the truck wouldn't of been able to fit in the garage. Is the trucks steel on top strong? What would happen if the truck did scrape? Would it just scratch the paint or would it sent the top of the truck. I'm pretty sure the truck would win against wood but idk what do you think? I'm just a little paranoid because I joust bought the the truck and I know it didn't hit the top of the garage but it was close and is the antenna damaged or not?
