Terms of Service

Acceptable Use & User Agreement

These Terms of Service govern your use of Smart Roofing Calculator. Our calculators and articles are provided as educational and estimating tools — they are not engineering or construction advice and should not replace consultation with a licensed roofing contractor or structural engineer for your specific project. We work hard to keep formulas accurate but make no warranty of fitness for any particular purpose. By using the site, you agree to use the tools responsibly and to verify any output before placing material orders.
