Parctile Estimating Guide

  1. The Tables below are for estimating purposes only. The figures quoted are based on nominal tile dimensions and are subject to normal manufacturing tolerances.
  2. Count all fractions of tiles as whole tiles.
  3. The table assume a simple mono-pitch or duo-pitch roof construction. More complicated roof structures will entail an additional wastage. We suggest an additional estimating figure of approx. 1.32 tiles x total linear metres of hips and valleys
