About the roof coverings calculator

The data for this calculator is based upon input from a quantity surveyor on real roofing jobs. Please note that it may be necessary to estimate the lengths of some of the roof dimensions rather rather physically measure them due to access difficulty – please stay safe!

The following terms have been used:

  • eaves – the horizontal row of tiles usually at the front and back of the house adjacent to the rainwater gutter
  • verge – the sloping edge of the roof from the ridge to the eaves
  • ridge – the horizontal tiles at the top of the roof
  • hip – the sloping tiles from the ridge to the corner of the roof.

Note that if the the roof configuration is hipped there will be no verge and if it is gabled there will be no hip tiles. The calculator works this out for you.

It should be remembered that the roofing costs displayed are indicative only and quotations should be obtained from reputable roofers.
