Yes or no --- putting a metal roof over one layer shingles
We are getting estimates now and I wonder what the reasons are for a tear- off if the roof isn't leaking? Is it just to inflate the estimate? We want to put a metal roof on a 2 1/2 car garage and the estimates are coming in very high.
The existing roof is only 8 years old but the shingles are starting to buckle. I think they were the least expensive shingles available. (One estimate claimed there were two layers of shingles so we would have to pay for two tear-offs. Not true.)
