Commercial Roofing Proposal Checklist: What to Include Before Submitting a Bid

Read the invitation to bid, request for proposal or site-walk notes before preparing the document. A privately negotiated maintenance job and a public reroofing tender can require very different submissions. Some requests specify a format, deadline, site access procedure, insurance thresholds or approved materials. Others expect the contractor to define the scope after inspection.

Record the bid due date, the person authorized to answer questions and the process for clarifications. If addenda arrive, verify that the estimating team has priced the latest documents. For public procurement, check the published solicitation and its amendments rather than relying on a forwarded summary. SAM.gov is the federal source for contract opportunities and related documents.

The first page should make the project unambiguous: building name, street address, contact, proposal date, reference number and any roof-area designations used in drawings. Multi-building campuses need separate schedules or quantities for each building.

Contractors can document conditions and quantities with CapXos Inspect and Takeoff, currently available as free tools. Their purpose is to organize field evidence; the estimator remains responsible for checking scope and measurements.

A roofing scope of work template is useful only when the project-specific details are actually filled in. Describe the existing system, proposed work and limits of responsibility.

Depending on the project, the scope may address:

• Tear-off or recover extent, including known layer assumptions.
• Inspection and repair of exposed decking, with clear allowances where appropriate.
• Insulation, cover board, membrane type, thickness and approved attachment.
• Tapered insulation, drains, scuppers and slope corrections.
• Parapets, edge metal, wall transitions, curbs and penetrations.
• Equipment protection, access routes and temporary weatherproofing.
• Waste removal, housekeeping and protection of occupied spaces.
• Testing, manufacturer inspections and closeout documentation.

Quantities deserve their own small schedule. Include roof area by section, relevant edge and flashing lengths, counts for curbs or penetrations, and a note explaining how the measurements were obtained. Distinguish field-verified dimensions from aerial estimates or drawings that need confirmation.

The earlier CapXos guide to moving from inspection to estimate covers the internal estimating process. The proposal takes those findings and turns them into a scope a buyer can approve.

Commercial roofing work can expose concealed conditions. Explain what the bid does not include, what is assumed and how discoveries will be handled. Examples include unknown deck deterioration, asbestos-containing materials, mechanical equipment relocation, electrical disconnections or unexpected moisture removal. These are examples, not a universal exclusion list; the project documents control.

An owner may request two membrane systems, additional insulation or an upgraded warranty. Price each alternate separately and state whether it adds to or replaces part of the base scope. Identify items that cannot be combined. If one alternate changes the schedule or access plan, say so beside the price.

For an occupied facility, disruption can be more consequential than the difference between two bids. State anticipated mobilization, work duration, normal work hours and any dependencies such as material lead times, weather windows or access permits.

Address areas that may require coordination:

• Loading docks, truck lanes and delivery windows.
• HVAC service schedules and equipment shutdown requests.
• Noise, odors, dust and sensitive tenants.
• Roof access, fall protection and restricted areas.
• Temporary protection during open-roof work.
• Daily site cleanup and emergency contact procedures.

Differentiate a manufacturer's system warranty or guarantee from the contractor's workmanship terms. Identify relevant conditions and whether the project requires an approved installer, manufacturer inspection or particular submittals. Confirm bond, insurance and licensing requirements where applicable.

Also list the records the client should receive when work is complete: photographs, inspection results, approved change orders, product information, warranty documents and any required permits or final approvals. Buyers should know what constitutes completed work.

Assign a second person, when possible, to compare the proposal against the request and inspection record. The review should confirm the correct property, roof areas, requested system, measurement schedule, alternates, exclusions, attachments, contact details and submission instructions. Read the PDF or web version exactly as the customer will receive it.

Start with the CapXos commercial property map if the address needs research, then use field documentation and takeoff quantities to support a proposal that can withstand detailed review.
