I'm tiling the roof of my lean to extension and will be using Redland Grovebury (double pantiles). Normally you would adjust the interlock to avoid cutting the verges but my roof is only 9 1/2 tiles wide and that's with overhang so I will need to cut a tile on each course. The question is, do I put all the cut tiles on one end or do I use a cut tile on alternative ends on each course?
