Which you probably sink into a second layer of asphalt shingles 15-20 years in (at least up here in upstate NY where there's plenty of rain/snow). Hopefully it's not a tear-off, as that'll cost more.
It's always tearoff. A lay over is saving 2k and shortening the life of brand new roof. Always a bad idea. Unless maybe selling the house soon to a naive buyer.
