Great roofer with excellent customer care!
jason did a fantastic job replacing a leaking flat roof, replacing broken tiles and lead flashings. As it was quite windy and wet on the first night, Jason drove out just to make sure our roof lights were secure and everything was battened down properly. Second day , the job was completed to an excellent standard and all working around a wet and windy couple of days to make sure we were leak free.
