What must the roof and building review establish?
Start with a commercial roof inspection that records the assembly, roof zones, drains, curbs, penetrations, edges and reported concerns. Compare plans with observed construction. Ask the building contact which rooms must remain in use, which routes are restricted, and what notice or interruption process the facility requires. Those decisions cannot be inferred from a typical business schedule.
The roof condition drives the scope. Limited deterioration may support repair; a roof recover and overlay requires separate moisture, attachment and detail checks. Broad removal calls for a commercial roof replacement plan with defined phases and closure points. Mark confirmed work separately from test openings and allowances for concealed conditions.
