Cookies

This site sets no cookie. It uses no local storage either: the calculators keep your inputs only in the page you are looking at, and in its address if you press "copy share link".

Why there is no consent banner

A banner is required when a site stores or reads information on your device that is not strictly necessary. Nothing of the kind happens here, so there is nothing to accept or refuse. The stability monitoring by Microsoft Clarity, described in the privacy policy, runs in a cookie-free mode and stores nothing on your device.

Check it yourself

Open your browser's developer tools (F12 on most computers), go to the Application or Storage tab and look under Cookies and Local Storage for this site while using a calculator: both stay empty. The Network tab shows that changing a state or a size sends no request; the result is computed on your device.

Estimate only: the ranges on this page come from public surveys and wage statistics, not from a contractor who has seen your house. Roof pitch, access, rot under old shingles, permit fees, brand choices and the season all move a real quote. Get two or three written quotes before you sign.
