A good pair of lads. To be fair, the other roofers I met also seemed knowledgeable and reasonable but it was Danny's willingness to discover the root of the problem and explain what was required. His diagnosis made logical sense to me and he provided photographs to back it up. His price was very fair considering the materials involved and I was very impressed that within 30 minutes of agreeing the work, he was back with the new roof vents, identical to the old perished ones. Time will tell if the damp problem is completely fixed but I feel confident enough. Fair price, quality materials, friendly and efficient, can't ask for more. Cheers
