Acceptance and permitted use
By using Tools for Roofers, you agree to these terms. You may use the site for lawful informational, estimating, and planning purposes. Do not interfere with the site, attempt to defeat its security, misrepresent outputs as certified work, or use it in a way that violates another person’s rights.
Informational calculations only
The tools are provided for convenience. Outputs can contain errors caused by software, input, measurement, rounding, assumptions, field conditions, or product differences. You are responsible for checking dimensions, units, formulas, product data, waste, code requirements, construction documents, and the suitability of every result before relying on it.
Important quantities and any result affecting safety, structure, drainage, weather resistance, purchasing, contracts, or compliance require independent verification by an appropriately qualified person.
No professional relationship
Use of the site does not create a contractor-client, architect-client, engineer-client, supplier, fiduciary, or other professional relationship. The site does not certify measurements, designs, code compliance, workmanship, or product suitability and does not represent an endorsement or partnership with a manufacturer, supplier, trade body, or authority.
No warranties
To the fullest extent permitted by law, the site and its content are provided “as is” and “as available,” without warranties of accuracy, completeness, availability, merchantability, fitness for a particular purpose, non-infringement, or that errors will be corrected. Nothing in these terms excludes warranties or rights that cannot lawfully be excluded.
Limitation of liability
To the fullest extent permitted by law, the site operator will not be liable for indirect, incidental, special, consequential, exemplary, or economic losses, or for losses arising from reliance on calculations, purchasing decisions, delays, data loss, property damage, or unavailable service. Where liability cannot be excluded, it is limited only to the extent the law permits. Non-excludable statutory rights remain unaffected.
Third-party information and changes
Product coverage, building practices, and external resources may change. Third-party names remain the property of their owners. The site may be modified, suspended, or withdrawn, and these terms may be updated. Continued use after an update means the revised terms apply from the updated date shown above.
