Terms of Service

By using CalculateRoofPitch you agree to the terms below. They are written in plain language because we want them read.

License to use the site

We grant you a non-exclusive, worldwide, royalty-free license to use the calculator and read the content on this site for personal, professional, or educational purposes. You may print individual pages for your own use. You may not republish, redistribute, or commercially reuse our content without written permission.

No professional advice

Content on this site is informational. It does not constitute engineering, architectural, or contracting advice for any specific project. Before relying on any number, code reference, or recommendation for a real-world build or repair, verify it against your local building code, your specific manufacturer's documentation, and the judgment of a licensed professional.

Accuracy

We work hard to keep math and code references accurate, but we cannot guarantee that every fact is current at the moment you read it. Building codes change. Manufacturers update specifications. If you find a discrepancy or out-of-date reference, please let us know — see the corrections section of our methodology page.

Disclaimer of warranties

The site and its content are provided "as is" without any warranties, express or implied, including warranties of merchantability, fitness for a particular purpose, or non-infringement. Your use of the site is at your own risk.

Limitation of liability

To the maximum extent permitted by law, we are not liable for any direct, indirect, incidental, consequential, or punitive damages arising from your use of the site, the calculator, or any content. If you build something that doesn't work and you blame the calculator, we are sorry — but we aren't the responsible party. Builders are.

Changes to terms

We may update these terms. Material changes are dated at the top of the page. Continued use of the site after a change means you accept the updated terms.

Governing law

These terms are governed by the laws of the United States and the state in which the site operator is registered. Any dispute is resolved in the courts of that state.
