I recently purchased my home and have been using my garage daily. I noticed a few weeks ago that paint and a little bit of wood is chipping off the door every time it opens.. is there an easy solution to fix this?

Take a close look at the track the door travels in on each side of the garage. There is an axle and roller attached to the door that rolls in this track. The rollers aren't adjustible but the track can be adjusted. Loosen the bolts that hold the track at the floor, middle of the door and at the top. You can move or pry the track away from the door frame just a few MM and then tighten the bolts. Try the door and adjust further if desired.
