Roofing Calculator & Estimator is the phone version of this site's calculators, free on Google Play and the App Store. It measures roof area and squares, finds the pitch, counts shingle bundles, sheathing, metal panels, screws and nails, and prices the job for asphalt, standing seam, stone-coated steel, tile, slate and cedar roofs. It works offline, in feet or metres and in English or Spanish, and saves estimates, compares up to three quotes, exports PDFs and builds a material list. Its metal roof calculator gives panels, screws, closures and minimum slope.
