I used this thread to find some roofers to get quotes from so I better pay that back I went with Inspired Roofing, they fitted a new flat roof, sealed the roof over my bay window, cleaned out the gutters, re-grouted ridge tiles, replaced a missing tile and repainted the house front and roof line which was looking very grotty.
The quote was reasonable, they came when they said they would, phoned first, were here most of two days and the work looks very smart. I'd definitely use them again.
