Ryan basically saved my bacon when my flat roof collapsed a week before I was due to go on holiday. His quote was very reasonable and he managed to shift some of his other jobs to come and replace both the roof and the ceiling two days after he gave me the quote. The work is of a very high standard and completed within two days, I would definately recommend Ryan for any of you building requirements
