Upload your projectA clearer read
A focused read of what moved between the documents.
It is “what, exactly, is different from the agreement I already have?” RafterSignal puts both documents side by side and organizes observations without deciding who is right.
Changed scope
See added, removed, revised, and potentially overlapping work in plain language.
Changed costs and fees
Surface changed allowances, new fees, markups, taxes, and missing labor or material detail.
Schedule differences
Notice timing changes and other schedule details that may need a follow-up question.
Missing details
Keep unclear wording and missing supporting information visible instead of filling in the gaps.
Questions for follow-up
Leave with practical questions for the contractor or a qualified professional.
The review path
From two documents to a clearer next step.
No verdicts. No invented details. Just a structured read of what the documents say—and what they leave unclear.

A shared reference
A clearer conversation for homeowners and contractors.
RafterSignal organizes the documented differences between an original agreement and a later request so the people reviewing the work can discuss the same details.
It is not an accusation, a negotiation service, or a determination of responsibility. The contractor-facing context does not replace legal, construction, or financial advice.
Read the fine print
Useful context, not professional advice.
RafterSignal distinguishes document facts from possible discrepancies, missing information, and matters that may need professional review. It does not decide whether a charge is valid, and it does not replace legal, construction, or financial advice.
Your report should make the next conversation more specific—not make the decision for you.
- Document facts are labeled and referenced when possible.
- Unclear wording stays clearly marked as unclear.
- The public sample uses illustrative documents and does not upload or analyze visitor files.
- Jurisdiction-specific questions belong with qualified professionals.
