Thanks to all who responede to my question, I have decided to go with a 30 year shingled roof. By the time it needs replacing it will be somebody elses problem....thanks again.
I am new to this forum and I have found some pretty valuable advice, so thanks to all of you....
My question is this, I am in the process of having an addition added to my cottage, now I need to add a new roof and I was wondering if I should shingle the entire roof or install a metal roof...
