A roof change order that explains the extra work

Start from a defined original agreement

A change order is understandable only when the original scope is clear. Keep the accepted quotation, appraisal and any location sketch together with a date or version number. When a contractor proposes something different, the new document should identify the original agreement and the specific item being changed. Replacing the old file with a revised total removes the history you need to evaluate the decision.

For a Toronto non-condominium low-rise roof, a change might concern newly exposed material, a different repair boundary or an owner-requested addition. Those are different reasons. Ask the contractor to say which applies rather than describing every extra as unexpected damage. The reason affects the questions you should ask.

Require a factual description of the finding

A useful record identifies what was observed, where it was found, when it became visible and why it was not included previously. Request photographs with context and relevant measurements from the professional. If the finding cannot be fully evaluated yet, the record should state that rather than treating a suspicion as a confirmed quantity.

In a hypothetical repair, opening an agreed junction might reveal material that requires further assessment. The change request should describe that material and the proposed next step. A close-up captioned more damage is not enough to explain a substantially expanded scope. Ask how the finding changes the feasibility of the originally approved repair.

Describe the proposed response and alternatives

The contractor should explain what additional work is proposed, what it is intended to accomplish and what remains outside its scope. Ask whether the proposal replaces an existing item or adds to it. If previously priced work is no longer needed, the change record should show how that is addressed in the revised amount.

Where there are reasonable options, request their different purposes and limitations. One option may involve further investigation before a permanent decision, while another may address a condition already established. You do not need an artificial menu when only one safe response is appropriate, but you should receive the reasoning behind that conclusion.

Make the cost understandable

Ask for the additional or reduced price, applicable taxes, revised total and any effect on payment timing. Identify whether a proposed amount is fixed for defined work or an allowance subject to further confirmation. A unit rate is useful only when you know what is being counted and how the final quantity will be documented.

A hypothetical change could add a measured task while removing an unused allowance. The revised total should show both effects so the homeowner can follow the arithmetic. Avoid approving a message that contains only a new grand total without the scope changes behind it. A clear explanation supports scrutiny without assuming dishonesty.

Record the schedule and temporary protection

Ask whether the change affects the work sequence, completion date or period during which protection is needed. If the roof is open, clarify what must be done immediately to maintain a safe and protected condition while a decision is pending. That discussion should have been anticipated in the original agreement where practical.

Genuine weather or safety constraints can require prompt action, but they should be explained separately from a broader permanent repair proposal. Request the purpose and limits of any temporary measure. Do not allow urgency to turn into undefined authorization for every possible additional task, and do not demand delay where it would create an avoidable hazard.

Approve a particular version through an agreed process

Identify who is authorized to approve changes and how written approval will be captured. The approval should refer to the actual scope and price version, not a vague instruction to proceed. Keep a copy accessible to both parties. If a discussion happens by telephone, ask for the agreed terms to be recorded before relying on that conversation later.

Ontario’s renovation guidance emphasizes written project details and documented agreement when work changes. For questions about your legal rights, consult the current provincial guidance and obtain appropriate advice using the complete contract. This page is a practical recordkeeping method, not a substitute for the applicable agreement or legal advice.

A practical change-record example

Hypothetical example: change C2 refers to finding R5, explains what became visible after the agreed opening, attaches two labelled photographs and proposes a defined additional task. It states the price effect, revised total, schedule impact and temporary protection while approval is pending. If you approve, the confirmation refers specifically to C2 and its date. If the proposed quantity later changes again, a new revision explains why. This may sound formal for a small job, but a short structured message can contain these fields. The value lies in clarity and traceability, not in producing a large document.

Reconcile the final invoice with the change log

At completion, match the original price and each approved change to the final invoice. Confirm that declined options have not become paid items and that approved work has a corresponding completion record. Ask for any remaining discrepancy to be explained in writing while the details are fresh. Retain the chronology even after the account is settled.

AI can help build a change log, compare versions and flag unexplained differences. It cannot determine from a photograph that an extra was technically necessary or legally owed. Ask it to quote the documents supporting each comparison and label missing evidence. Use the resulting questions with the contractor instead of treating an automated summary as approval.

Compare the evidence before deciding.
