Calculator information

Roofline calculates estimates in your browser. We do not ask you to create an account or enter your name or property address to use the calculators. Measurement inputs are kept in this tab’s session storage so your plan carries between calculators and survives a reload. They are not sent to an application database. Use Reset example to clear your plan; closing the tab normally ends the stored session.

Google Analytics

We use Google Analytics 4 to understand page visits and calculator use. Google receives technical information such as your IP address, browser and device details, and analytics cookies. Our custom events report the calculator page you use, not the measurements, section names or prices you enter. We remove query strings from the page URLs we send and send only the origin of the referring site.

For visitors in the EEA, UK and Switzerland, Google’s certified consent message controls advertising and analytics consent and offers Consent, Do not consent and Manage options. You can reopen it or withdraw consent through Privacy settings at the bottom of any page. Elsewhere, Analytics is on by default and you can turn it off at any time through Privacy settings at the bottom of any page; turning it off stops measurement, removes the Analytics cookies and is remembered on this device for up to 180 days. If your browser blocks the consent service, we cannot tell which rules apply to you, so Analytics stays off unless you allow it. Visit Google’s privacy policy for information about its processing.

Website delivery

The site is delivered through Cloudflare. Loading a page sends normal request information, such as your IP address, browser information and requested URL, to Cloudflare so it can deliver the pages and protect the service. Cloudflare may set a strictly necessary security cookie for that purpose.

Advertising

Roofline loads the Google AdSense publisher tag to present the consent message and prepare advertising. The site is not currently approved to show ads, so none appear. If that changes, Google and its selected ad partners may process device information and use cookies to serve and measure ads in line with your consent choices.

Contacting us

If you email us, we use your address and message only to answer you. See Contact.

Manage your choices

Use Privacy settings at the bottom of any page to change or withdraw your consent choice or to turn Analytics off. You can also control cookies in your browser settings.
