RoofReady

Plan materials for a simple gable roof with clear, practical estimates.

RoofReady turns basic building measurements into a sloped roof area and purchase-ready estimates for shingles, bundles, and underlayment rolls. Enter building length and width, eave overhang, roof pitch or separate rise and run, waste percentage, and the coverage printed on your chosen products.

Use imperial or metric units, switch between light and dark themes, and reset the calculator whenever you want to start over. Every result clearly states the assumptions behind it, including rounding whole product counts up.

RoofReady is designed only for rectangular, symmetrical gable roofs. It does not model hips, valleys, dormers, irregular outlines, openings, structural requirements, or local building codes. Confirm measurements, product specifications, and installation requirements with a qualified roofing professional before purchasing or installing materials.
