Download the Roofing Estimate & Material Takeoff spreadsheet: enter the building size, overhang and pitch and it calculates sloped area, squares, shingle bundles, underlayment rolls, ridge cap, starter strip, drip edge, valley flashing, nails and attic ventilation with the same math as Smart Roofing Calculator, then prices it on a printable quote. Also available: a contractor job quote and change-order template, drywall and insulation estimators, a renovation budget planner and a 10-tool contractor bundle. Every workbook opens on a Start Here sheet with a colour legend and worked example, ships with a printable PDF guide explaining each formula, and runs the same in Excel, Google Sheets and LibreOffice. Prices are editable placeholders, so contractors can load their own supplier costs, labor rates, markup and sales tax before sending a quote.
