I thought I read that when a roof is replaced, it can be re-shingled over the old ones or stripped down and started over. (Now I've searched online and see that it is an option up to two additional layers.) ...
Is shingling-over quite acceptable?
What are the life expectancies of each?
It would seem the shingle-over method would be less expensive?
Thanks.
(We were just told that the new roofing was put on over the old roofing and that is bad and shouldn't be done.)
