I need to have new shingles on my roof. There are two layers of three

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?

????? Are you sure that you understood the roofer correctly???

State of Maryland says that you can have a max of two layers of shingles
on roof. If you already have the two layers...it makes sense to remove
both of them and start with a single layer again. Never heard of anyone
removing just one layer...as the bottom one will be damaged no matter how
careful they are. This also gives you an
opportunity to inspect the panels, install new felt and flashing.

I would think that the only additional cost would be for hauling the
extra shingles away.
