Store description excerpt

Calculate roof area and tile requirements in seconds — right from your iPhone or iPad. 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. Whether you're planning a new build, renovating a house, or just estimating material — RoCa gives you sensible numbers instantly. ▸ SIX ROOF SHAPES • Gable / saddle roof • Hip roof • Half-hip roof • Mono-pitch / shed roof • Tented / pyramid roof • Through-roof ▸ SIMPLE INPUT Length, width, eaves overhang, slope angle, and where needed, ridge length or hip height. 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. Your input never leaves the device. No sign-in, no account, no cloud. ▸ MODERN Built for iOS 16+. Dark mode, German, English, iPhone and iPad.
