Why it's important NOT to go over your existing roofing shingles!
Failing to remove old detiorating shingles and simply laying a new roof over the old can lead to major problems that can be quite expensive.
Picture this for a minute: Imagine you have a mold issue caused by a leaky or poorly ventilated roof and you put up a brand new roof without inspecting and replacing the bad sheathing. Eventually when the mold and rot gets bad and it will, you will need to remove your newly laid roof as well as the old one beneath it at an increased cost to fix the problem.
