Estimate comparison
Roof estimate comparison
Compare three roofing proposals by roof measurements, materials, deck allowances, installation scope, and written terms.
Compare the written scope before comparing totals. Use the same project description for every contractor. Leave unknown items blank and request clarification; this worksheet does not specify the design or construction requirements for your project.
Entries stay in this tab; this worksheet does not send them anywhere. Print or download your completed worksheet to keep it before closing the page.
1. Align the scope Give each contractor the same dimensions, use, and requested work.
2. Record differences Write “excluded” where the estimate excludes work. Do not treat blanks as included.
3. Clarify in writing Resolve allowances and unanswered questions before selecting a proposal.
