Colindale's United Reformed Church in Northwest London (NW9) contacted us with an enquiry about an urgent job on their flooded single storey roof. They attached drawings, notes, and pictures, giving us a thorough idea of the problem, and added that channels would need to be formed in the exiting levelling screed to aid drainage. They also told us new pans and connections would be required at the two drainage points. They were particularly impressed by the guarantee we are able to offer.
