About RoofSheetCalc

Free, accurate, India-specific roofing calculators — built for the people who actually build sheds.

What Is RoofSheetCalc?

RoofSheetCalc is a free, browser-based toolkit for anyone working with roofing sheets in India. It provides calculators to determine sheet quantities, compare material types, plan purlin layouts, and estimate roof dead loads — all without registration, apps, or fees.

Every tool runs entirely in your browser. No data is sent to any server. You can use the calculators on a phone at a construction site and get results in seconds.

Who Is It For?

  • Contractors and fabricators who need a fast, reliable sheet count before placing a material order
  • Shed builders quoting for agricultural, industrial, or residential projects
  • Civil engineers and draughtsmen who need dead load figures for structural calculations
  • Hardware dealers and distributors helping customers estimate quantities
  • Self-builders and farmers planning a shed or poultry house without a contractor
