I have a twenty-two year old home. I am assuming that the builder quality shingles used in construction of the house mean I should be looking at a new roof...soon!
This will be the first roof I have ever replaced. One company, check-rated in the local consumer guide, came and gave me an estimate for reshingling over the old roof.
Another company, with a good reputation but not check-rated in the same guide, said they would not re-roof over an old roof and gave me what sounded like reasonable reasons for so arguing.
Leaves me up in the air: two seemingly good companies, one saying reshingle, the other saying don't.
What's the common wisdom on this? Reshingle or tear up the old shingles and do a new roof?
Many thanks, bob
