I'm sorry but I cannot recommend David from Norwood Roofing. I found him rude, discourteous and when he wants his money, he is very aggressive. His prices were expensive but I used him because of his guarantee. I have had to ask him back to deal with a recurrent problem on a roof, but he has given up on this problem all together and says it has nothing to do with him. A guarantee isn't worth the paper it is written on unless the tradesman comes back to have another look. It's a shame but please think twice before using him.
