On most jobs, a Outer Mission estimate worth reading itemises tear-off, disposal, underlayment, covering, flashing, permit and clean-up separately. Worth knowing before you sign anything. A Outer Mission quote that comes in far below the others is usually missing the flashing, the permit or the disposal.
