Commercial Roof Replacement Planner
Useful assumptions.

Model roof-system work, tear-off, insulation, deck allowance, access, complexity, and contingency using actual roof area.

Versioned planning model

Commercial roof replacement planning range

Adjust the known inputs. The result remains a conceptual planning range.

Cost basisMidwest / South-central preliminary planning assumptionsEffectiveJuly 2026Assumption set2026.07.1
Conceptual result • Preliminary confidence$270,000–$620,000

Roof-system work plus separately modeled allowances

Adjusted roof-system allowance$150,000–$320,000
Tear-off and disposal$30,000–$70,000
Insulation allowance$50,000–$140,000
Deck repair allowance$3,000–$8,000
Contingency (15%)$35,000–$80,000
Why the result moved
  • TPO replacement
  • Typical commercial roof
  • Standard Regional Market
  • 2% provisional deck repair area
  • Baseline size factor

Important limitation. Roof scope cannot be determined from age and area alone. Moisture scanning, core cuts, drainage, deck, structural, code, attachment, hazardous-material, and manufacturer requirements may materially change the solution.

Planning estimate only.

Calculator results are conceptual ranges, not bids, guarantees, engineering opinions, or financial advice. Actual requirements depend on verified scope, existing conditions, selections, access, market pricing, design, and approvals.
