"Piling up layers of shingles?" It is an overlay, a common roofing procedure. Are you aware of that?

Andy Ross: An overlay used to be a very common practice but nowadays most homeowners want the entire roof stripped so not to cover over any damaged plywood or flashings that need replacement. Also, did you know the roofing manufacturers warranty is void with an overlay and three layers is the maximum in most States?
