Step 8 of 8
Whether any claim on the quote is verifiable without trusting its author
How to check it
Every previous step verified a claim against a registry someone else operates. Some contractors now go one step further and publish their business claims — certifications, insurance posture, service scope, warranty terms — in machine-verifiable form: structured statements with content hashes, so that any copy of a claim can be checked byte-for-byte against the published original from anywhere, by anyone, without asking the contractor. The general test this adds to a quote is simple: a claim that can be independently verified anywhere beats one that exists only as marketing, and the fraction of a quote that survives independent checking is itself information.
A generic practice, not a single registry; each publisher's verification surface is its own. No company is named here.
What a pass proves
That the claim's author committed to it publicly and tamper-evidently — the claim on the quote is the claim the company actually publishes, not a paraphrase softened for the sales visit.
What it does NOT prove
The permanent caveat of this entire walk: verification proves claims are real, not that a roof will be good. Workmanship has no registry. What verification changes is the residue — after it, whatever trust remains is being extended knowingly, to the small set of claims that cannot be checked, instead of to all of them.
No checklist replaces reading the actual quote.
These checks tell you whether the claims on a quote are real; the quote itself tells you what is being sold. Get a quote you can run this walk against, or book the inspection that answers what no registry can.
