You can go up on the roof if you span the roof trusses with a sheet of plywood. But you got to be very careful. By the way, I wouldn't recaulk, I'd use Eternabond tape.

Thank you for the response. We do have the Eternabond tape also. That plywood method scares me, I am glad that I am not the one having to go up on it!!
