Why this site exists
Search for anything about roof insurance claims and nearly every result is published by a roofing company, a public adjuster or a law firm — people whose income depends on which way you decide. Their calculators are lead forms with arithmetic attached.
We do not replace roofs, adjust claims or sell your details to anyone who does. The calculators are ungated because the absence of a gate is the point. Every assumption is visible and editable, the method is published, and the limitations are listed alongside the result rather than hidden.
If a figure here disagrees with your adjuster, the adjuster has your policy and we do not. Use this to ask a better question, not to win an argument.
