Harry came very quickly and we agreed a price, he noticed the ridge tiles were very loose above the vent tiles that were leaking and said they were most likely the main cause of the leak . There were also two cracked tiles which he also changed and some mortar missing from the front of the roof which he filled. I am very happy with his work and prices and have already asked him to do another job for me when he is available. After Harry left I went into my roof space and found the insulation was wet directly below where the loose ridge tiles were, so if he had not noticed that and just done the job I asked him to do I would still have the same problem after he left.
I highly recommend Harry.
