Buildings within one association may have different roof systems and conditions. A single price without building-level scope can hide important differences. The comparison should show what is proposed for each roof and why.
What to do next
Provide a consistent building list and available records to every bidder. Ask for separate findings and assumptions by structure. Where work is phased, explain how priorities were chosen rather than treating building order as a purely administrative decision.
