Roof inspection.

Have never been on my roof. Have no plans to ever get up there. I'm almost 75 years old, balance isn't great and I've always been a big guy. I would like to have it inspected and have the caulk touched up if it needs it. I don't want some opportunist to take advantage of me and tell me I need a complete strip it all off and re-do it thing. I have always had them touched up in the past and it's worked well. At this time I don't have or know anyone that will do this. What are your suggestions? Not having any problems right now but don't want any either.
