We would rather show you than tell you. Every figure below was computed moments ago, on the server, by the same deterministic functions that run the free Material Calculator and the estimator's labor model — against the example jobs described. Each total is a direct cost basis (materials + installed labor + permit), before your overhead, margin, and tax. No screenshots. No stored numbers. Every labor line shows its full working, and typing a card's inputs into the free calculator produces the same material list and total.

Calculated from your inputs, without AI

Same inputs, same answer, every time. That is what makes it reproducible and trustworthy.

Reproduce it free

Type a card's footprint, pitch, roof type, grade and region into the free Material Calculator, leave the options at their defaults, and press Calculate — same function, same list. Plan crews in the Labor Estimator. No account required.

Computed at Oct 22, 2026, 3:01:35 PM UTC · Refresh and the time changes — the results don't, because they are math, not marketing. Example jobs are illustrative scenarios at the engine's default rates, not customer data; in your account you configure your own supplier and labor pricing.

Residential re-roof — architectural shingle

A suburban home re-roofed in standard architectural shingles; medium labor complexity (a few hips and valleys).

Calculator inputs

Type these into the free Material Calculator, as listed, and press Calculate. Leave the roof surface and the optional ridge, valley, hip, eave and rake fields blank (press Reset if the form holds an earlier draft). The roof surface shown is what the calculator derives from the footprint and pitch.

Frequently asked questions

Are these numbers real or just for show?

They are real output, computed on the server every time this page loads, by the same deterministic functions that run the free Material Calculator (materials) and the estimator's labor model (labor). Nothing here is a screenshot or a stored figure.

What does each total include?

Each total is a direct cost basis: materials (the free Material Calculator's list for the card's inputs — primary roofing, underlayment, accessories, fasteners, its region adjustment and its 5% extra line), installed labor (crew-hours × the region's hourly rate), and the permit estimate. It is intentionally before your overhead, profit margin, and sales tax — that is where your own markup goes when you turn this into a customer-facing bid.

Can I reproduce these results myself?

Yes. Open the free Material Calculator, type the footprint length and width, pitch, roof type, grade and region listed on the card, leave the roof surface and the optional ridge, valley, hip, eave and rake fields blank (0), leave Ice & Water, Ridge vent and the 5% extra option at their defaults, and press Calculate: the list and its total are produced by the same function that computed this page. If the form already holds an earlier draft, press Reset first. The labor line prints its full working on the card (crew-hours × hourly rate × the region factor, rounded to the dollar), so you can check that arithmetic directly. The default supplier and labor rates are the documented defaults; in your account you configure your own.

Does this use AI?

No. These costs are calculated from the inputs shown, without AI. Anything drawn from a photo, including size or cost, is a draft: verify measurements and costs before you quote.
