Well, I have to say I'm very impressed.
Douglas came to inspect the job on Thursday, and after looking both outside at the roof, and inside the loft area, he explained that my roof was rotten and needed replacing.
He showed me the state of the roof lats etc from inside which were clearly wet and rotting and after he itemised what needed doing including local hiring of scaffolding/skip and we agreed to go ahead.
Monday came and the scaffolding went up early in the morning, shortly after Douglas and his workforce arrived, as soon as the scaffolding was up they set to work and had the entire roof stripped within a few hours.
By the afternoon, roughly 8 hours after starting, I had a complete new roof, and he had undertaken a chimney repair after we negotiated the additional expense.
Thursday the scaffolding was down and skip collection arranged.
I have to say I'm impressed with his speed, and attention to detail, the work is guaranteed for 15 years but I don't expect to have to call him again.
Overall despite the severity of the work needing to be done, Douglas was professional, courteous, above all speedy, and answered any queries I had regarding the work.
I'm happy to firmly recommend him to anyone who may need roofing work done in the future.
For reference my house is a mid terrace, about 18 feet wide and 26 feet deep just to give an idea of how much roof area he had to replace.
