I need to have new shingles on my roof. There are two layers of three
tab shingles on there now. The roofer indicates that he will remove
one layer and then reshingle. Don't I need both layers removed. The
cost can't be that much more to remove the second layer. I have a
simple 1200 sq ft ranch 40 years old. What are the thoughts?

can you even get the top layer off without damaging the bottom layer?

it would be silly to leave a layer on.
