What We Do
We turn established roofing formulas into fast, accurate tools you can use in seconds. Instead of hiding the math, we wrap it in plain-English explanations of what the result actually means for your project.
Whether you need to calculate material costs, determine exact square footage, or figure out pitch multipliers, our calculators provide the answers instantly, directly in your browser.
Our Story
Roof Square Footage Calculator began out of frustration: most online construction calculators hand you a number with no explanation, no sources, and a page buried in distracting ads. We wanted to build the exact opposite.
What started in 2023 as a single clean tool for a local roofing crew quickly grew into a comprehensive library of calculators and guides — each one built to show its working and respect your privacy.
Our Trusted Source Statement
We earn trust the hard way: by showing our assumptions, citing recognised industry standards (such as the International Building Code), and being entirely honest about what a preliminary screening number can and can’t tell you. Every calculation is auditable, meaning you can check the math yourself.

"Finally, a tool that doesn't just spit out a generic number. It actually explains the waste factor assumptions. Highly recommended."
