Start with the outcome, not a roofing product
Before requesting proposals, state whether the immediate goal is interior protection, leak diagnosis, a durable repair, warranty maintenance, restoration, or replacement planning. Include the roof areas involved, known system information, leak history, prior repairs, occupied hours, and access constraints.
Give every contractor the same site information
- Roof plans, warranty records, inspection reports, and repair history that are available
- Known leak locations and the conditions when water appears
- Rooftop equipment, tenant, security, and access restrictions
- Required photos, moisture findings, schedule updates, and closeout documents
- The owner representative who can approve investigative or change work
Compare scope details before comparing totals
Review preparation, materials, repair limits, drainage details, interior protection, access, phasing, exclusions, allowances, warranty terms, and responsibility for permits or manufacturer requirements. If one proposal assumes a small localized repair and another includes wet-insulation replacement or broader flashing work, the totals are not describing the same job.
Prepare for the next leak before it happens
Keep roof access instructions, after-hours contacts, interior protection supplies, electrical or equipment contacts, and approval limits available. During an incident, separate temporary stabilization from the documented permanent-repair recommendation.
