01
Use the specified product information
Ask the contractor which underlayment is proposed and how its installation and exposure requirements affect the schedule. Do not assume that every membrane or felt can remain uncovered for the same period or under the same conditions. Review the plan for openings, transitions, and weather protection before the existing roof is removed.
02
Keep temporary and permanent work connected
Discuss how the roof will be closed at the end of each work period and who assesses temporary protection after weather events. If the project is delayed, have the contractor review the actual condition and applicable product guidance before continuing. Keep records of any replacement or corrective work. Temporary protection is part of project planning, not proof that an unfinished roof performs like the final slate assembly.
