So I woke up this morning and what greeted me is a dimple on my roof. I live an apartment with no garage. I thought it was just a water droplet, so I wiped it clean, and there is a small scratch. I have no problem with the scratch since that can be easily covered. What I am bothered is now I have a dimple right in the middle that is very very noticeable even from afar. I know its not a rock, or a coin since I know it cant produce such dent. And the ground was clear, even my windshield and roof is clean. Our building is a 4 story one, and I only suspect some a$$hole who lives upstairs just decided to practice target shooting on my roof.
How can this be repaired since it bothers me everytime i look at it. Any actions you guys suggest that I could do to further my investigation of how the hell that dimple got there. Oh man, I hate this.
