What belongs in a complete roof replacement?
A complete scope names the new covering, compatible underlayment, flashing, edges, penetrations, ventilation details, disposal and cleanup. It also explains how exposed deck damage will be documented and approved before added work proceeds.
Does roof replacement include full tear-off?
Full tear-off removes the existing roof layers before the new system goes on. A layer-by-layer removal plan makes the existing assembly visible as work progresses; if an overlay is proposed instead, compare its product instructions, remaining roof layers and concealed-deck limits.
How should I compare replacement proposals?
Compare the roof system by brand and product, removal method, flashing details, deck-repair pricing, ventilation work and cleanup. GAF notes that overlay can conceal roof-deck conditions, so the proposal should state how hidden conditions will be handled.
