Occupied properties need a sequence that keeps entrances, loading areas and critical rooms protected. A retail roof may have customers below and deliveries at the perimeter. Apartments add resident circulation and notice windows. Offices can have sensitive rooms, meeting schedules and after-hours access. We ask which operations cannot stop, then locate roof openings and daily tie-ins around those limits. Temporary protection is planned before removal begins. The scope can separate phased reroofing, targeted repairs and scheduled maintenance as different options.
