RoCa is the fast, no-nonsense roof calculator for anyone who needs to know how many square meters of roof they have and roughly how many tiles they'll need.

Use sliders or the keyboard. Live preview shows which dimension you're currently editing. ▸ PRECISE MATH Clean geometry implementation — no rough rules of thumb, no lookup tables with rounding errors. Proven formulas per roof type, including overhangs. ▸ TILE PICKER Pick a tile type and RoCa estimates the count automatically: • Frankfurter pan tile (~10/m²) • Double-pan interlocking tile (~12/m²) • Plain tile, double-lap (~36/m²) • Large-format tile (~8/m²) • Smooth flat tile (~10/m²) • Generic average (~15/m²) ▸ SHARE Send your result by message, email or AirDrop. ▸ OFFLINE-FIRST All calculations run locally.
