Flat-roof plan area calculatorin Ipswich

Calculate the rectangular plan area from dimensions already available from drawings or a safe ground-level measurement.

Use the tool without an enquiry. Your answers stay in this page while it is open; they are not sent, saved or added to a URL by the tool.

Before you begin

Use existing drawings or dimensions obtainable safely from ground level. Never access a roof to use this calculator.

This interactive aid needs JavaScript. You can still read the assumptions and use the related service guides below without it.

Assumptions and limits

  • Area = plan length × plan width. An entered allowance adds that percentage to this plan area. Enter 0 for no allowance.
  • This is for a single rectangular plan, not a pitched roof. It excludes upstands, falls, kerbs, outlets, overlaps, laps, trims and complicated shapes.
  • The result is not an order quantity, a structural assessment or a complete waterproofing specification. Ask the roofer or system supplier to measure and specify the actual system.
  • Do not climb onto a roof or use a ladder to obtain these measurements.
