About Smart Roofing Calculator

Smart Roofing Calculator (Roofing Calculator & Estimator on the App Store) helps roofers, contractors, and homeowners estimate roofing materials and cost in seconds. Calculate squares, shingle bundles, underlayment, and pricing — on the truck, on the roof, or at the desk.
