To the top and right shows the re-roofing of a large farm house, the owner  having

insisted on the retention of as much of the original as possible .The tiles are removed and the timbers inspected, those to be saved are de-nailed and treated with

a preservative .Any which are beyond saving are replaced. The chevrons are counter

battened, covered with a breathable waterproof membrane and then battened. This

system allows the free passage of air and aids ventilation. The old hand made tiles

are sorted, good from bad and stored. New crochet tiles are fitted and covered with

the old tiles with the addition of tile clips to prevent slipping. To the left the author

strength of this design allows for a" room in a roof" which is essential for this cottage  design
