Just to update the nice people here who gave me some advice while I researched my roof style and contractor. (GAF Slateline English Grey, full rip to wood) NO rot was found and the house was sound.
I have some fantastic pics of the job but cant seem to post from my hard drive (any suggestions?) Contractor completed job in 14 hrs, cleaned up everything, new skylight was installed as well.
Again, thanks for the responses to my posted questions and good luck to the others here on their road to a new and better roof! :mrgreen:
