What a commercial roofing bid should identify

A roofing bid needs a defined assembly and work boundary. It should also address staging, access, protection and closeout requirements where applicable.

Ask each bidder to list assumptions about roof areas, openings, access, safety and material delivery. Compare exclusions alongside the price to see which scope needs clarification.

A bid should be specific

A commercial roofing bid should let you compare proposals fairly. If it is vague, the numbers may not be comparable.

What it should identify

• Roof area and system proposed.
• Tear-off or recover approach.
• Insulation, flashing, drainage and edge details.
• Warranty terms and who provides them.
• Exclusions and allowances.
• Schedule and access assumptions.
