How to Compare Commercial Roof and Envelope Repair Proposals

Before comparing the totals, check whether both contractors are pricing the same work. A defined repair, an investigation and temporary stabilization can all respond to the same leak report—but they do different jobs.

Illustrative scope comparison: a defined repair and an investigation are different jobs. Clarify the purpose before comparing price.SAME LEAK REPORT ≠ SAME WORKPROPOSAL ADefined repairPROPOSAL BInvestigationClarify purpose and uncertaintyThen compare like-for-like scope.
Illustrative scopes, not actual bids. Neither price tells you whether the proposed work is suitable for your building.

Put the proposals side by side. For each item below, record what A includes, what B includes and what you still need answered. Write “not stated” where a proposal is silent.

Compare these seven items

  1. Purpose and location. Which roof or wall area is covered? Is the work meant to investigate, stabilize or repair? If the leak source is unconfirmed, does the proposal say so?
  2. Work included. Look for a defined area and actual work steps. “Repair as needed” needs clarification before it becomes a useful scope.
  3. Assumptions and exclusions. What is outside the price? If concealed conditions change the work, how will the contractor document them and obtain authorization?
  4. Access and scheduling. Who arranges roof access, staging, tenant notices and permitted working hours? What depends on weather or other work?
  5. Price basis. Compare the base work, allowances and separately priced options. Ask what could change the total.
  6. Closeout records. Are dated, location-labeled photos or a written work record included? What unresolved items will be documented?
  7. Warranty. If offered, read who issues it, what it covers, how long it lasts and its exclusions. Do not infer coverage from the material name.

A scope difference worth resolving

Suppose one proposal names a specific flashing repair while the other offers to investigate the reported leak first. The totals are not directly comparable: one assumes a defined repair; the other is intended to establish what work is needed.

Ask: “What finding supports this scope, and what remains uncertain?” This is a hypothetical example, not a Clearline project or a judgment that either approach is right for your building.

Get the clarification in writing

Send both contractors the same location reference and work objective. Ask for a revised scope where an important boundary is unclear. Keep the original proposal and date each clarification so the final decision can be traced.

Use the agreed scope and signed contract for the work actually authorized. This checklist helps compare documents; it cannot determine whether a technical repair is suitable for a particular building.

Still unsure whether you are comparing the right repair?

Clearline's targeted roof and envelope assessment addresses the condition and next decision when the scope is unclear. Its Service and Repair page explains defined corrective work. Larger replacement or restoration belongs under Capital Projects.

Discuss your roof or envelope concern with Clearline. Explain the affected area, what has been observed and what decision you need to make.
