FREE TOOLS · 4 CALCULATORS
Free tools for operators.
Standalone calculators — no signup, no email. The operator-economics math funded software makes you do by hand, built by the team behind Roofing OS.
Roofing Profit Margin Calculator
Free roofing job profit calculator: enter squares, price per square, material and labor cost, and any supplement recovered to see revenue, gross profit, margin, and profit per square.
Shingle Squares, Bundles & Waste Order Calculator
Turn roof surface area into squares, bundles to order, and field-shingle material cost with an adjustable waste factor. See the waste allowance in real dollars so you order once, skip the return trip, and stop quietly eating over-orders on every job.
Roofing Sales Commission Calculator
Model a roofing rep's pay on a gross-profit commission with a monthly draw. See commission per deal, monthly earnings, what the rep takes beyond their draw, and what the company keeps — so you design a comp plan that pays winners and does not bleed on slow months.
Roofing Overhead and Profit (O&P) Calculator
Add overhead and profit ('10 and 10') to an insurance line-item subtotal, then pressure-test it against your real cost and true company overhead. See total RCV, your actual net profit, and true net margin so you know whether a storm job is as good as the estimate looks.
The numbers behind the decisions.
Most software built for residential roofing contractors (storm + retail) handles the workflow but leaves the economics to a spreadsheet — pricing, margin, break-even, commission, capacity, and ROI. These are the calculations that decide whether a job, a hire, a plan, or a price is actually worth it, and they usually live in a founder's head or a tab that never gets opened.
Every calculator here is free, instant, and runs entirely in your browser — no account, no email, nothing stored. Adjust the inputs and the outputs update live. Each one is a planning estimate meant to inform a decision, not replace your accountant. They're the same operator-side math Roofing OS keeps running automatically once the guesswork is behind you.
Take one working workflow, free.
The after-service follow-up workflow from Roofing OS, whole and unmodified: import it into n8n and it runs on its own. Plus six short emails over three weeks on where it fits. Then at most one a month.
