Terms
Terms of Use
Effective date: September 20, 2026 · Last updated: September 20, 2026
By using RoofingShingles Calculator's free calculators or Roofing Estimate Pro, you agree to these terms. If you do not agree, do not use this application.
What these tools are
Every calculator on this site, and Roofing Estimate Pro itself, is a planning and estimating aid. Every number these tools produce depends entirely on the measurements, prices, waste rates, and other assumptions you provide. These tools do not measure your roof, verify a supplier's price, or inspect a jobsite -- they calculate from whatever you enter.
Not professional advice
Nothing produced by this application is engineering, structural, legal, tax, or other professional roofing advice. It does not replace a licensed contractor's inspection, a structural engineer's assessment, a tax professional's guidance, or your own compliance review of local building codes and permitting requirements.
You are responsible for verifying results
You are responsible for independently verifying your own measurements, local building codes, material requirements, labor requirements, applicable taxes, and final pricing before relying on any result from this application. No result from any calculator or from Roofing Estimate Pro is guaranteed to match a supplier's invoice, actual jobsite conditions, or the final cost of a real project.
Local storage is not guaranteed permanent
Roofing Estimate Pro stores your data locally in your browser. That local storage is not guaranteed to be permanent -- see the Privacy Policy for the specific ways local data can be lost. This application is not a backup service. You are responsible for downloading and retaining your own backup files.
Acceptable use
You may not misuse this application, attempt to interfere with how it runs, or attempt to gain unauthorized access to any part of it or the systems that serve it.
Availability
Features, pages, and availability of this application may change, be added, or be removed at any time, without notice.
Ownership
The design, text, and code that make up this site belong to its operator. The estimates, price-book entries, and business settings you create belong to you; they are your own data, stored on your own device.
No current commercial terms
No payment processing or paid subscription is enabled on this site today. Any price shown describes a planned future offering, not an active transaction -- no billing, payment, or money-back terms currently apply, and nothing on this page should be read as describing any.
Changes to these terms
These terms may be updated, and the "last updated" date above will change when they are. Continued use of the application after an update means you accept the revised terms.
