Roof maintenance

I will be inspecting my roof more often. I had my Montana in to have the A/C looked at since it wasn't cooling as well as it should. The service guy called when he went up on my roof and found a scrape and tear in my roof apparently from a tree limb. We had just gotten back from a long vacation and it either happened on the way home or when I was bringing it to the Service Center so I was lucky it was caught so soon.
