All Roofing Calcs

All Roofing Calcs puts 44 roofing and gutter calculators on your phone. They estimate roof area, squares, shingle bundles, underlayment, edge metal, fasteners, framing, ventilation, drainage and installed cost. Each one gives you a line by line breakdown instead of a single total. Each roofing calculator are built for homeowners planning a roof or gutter job and for contractors pricing one. The app works fully offline. Every calculator runs on the device. You do not need an account, a sign in or an internet connection, so it works on a roof or in a supply yard with no signal.

The result comes back as a materials list in whole purchase units (squares, bundles, rolls, panels, pieces) with a cost band beside it. Each calculator remembers your entries, so you can close the app and pick up where you left off. You can save estimates to come back to later and share any result as plain text with a client, a crew or a supplier. WHERE THE NUMBERS COME FROM The app runs the same calculation code as allroofingcalcs.com, carried over unchanged, so a job entered in both returns the same answer. Each calculator states its assumptions (coverage rates, waste factors, price anchors) and shows the work, so you can trace any figure back to the step that produced it. Where a method follows published guidance, such as the IRC, ASCE 7 or the SMACNA gutter method, the calculator names it. Cost figures use United States national average prices. Treat them as planning estimates, not bids. Your supplier's price and a contractor's quote will always be more accurate than a national average. PRIVACY The app collects nothing. There is no account and no sign in, and nothing leaves your phone unless you choose to share a result. The sponsor blocks in the app are editorial, unpaid links, not advertising.
