What information helps a roofer price a commercial bid package?
Provide current roof plans, assembly details, curb and penetration schedules, phasing, access limits, insulation and deck assumptions, and the project calendar. We identify field questions and exclusions before pricing. If the plans do not show existing conditions, the proposal states what a site walk must verify.
How should responsibility be divided at a new rooftop unit?
The contract should assign unit support, disconnect and reset, curb dimensions, temporary protection, flashing, and post-installation testing. We can define the roofing tie-in and coordinate the sequence with the mechanical trade. The GC confirms who accepts each interface before work starts.
Can the roof be opened before all equipment is ready?
Only when the opening can be protected and secured within the weather window. We coordinate the work area and dry-in point with the superintendent, then identify who controls temporary cover if another trade is delayed. A schedule should not leave insulation or deck exposed without a responsible handoff.
What should a roofing change order include?
It should tie the added condition to a roof zone, photographs, measured work, material and labor effect, schedule impact, and approval point. We document concealed conditions before extending the scope. That gives the owner and GC a field record for the change rather than a general note after the area is closed.
How do roofing crews coordinate with occupied-building work?
The GC and facility contact identify entrances, loading, noise windows, overhead protection, and areas that must remain available. We set a phase boundary and daily handback around those constraints. The scope says what becomes watertight and what access remains restricted before the next trade works below.
