Please be warned before you use this guy, i had a full roof refit that lasted 9 months before it failed, i tried to contact this company about it but have been ignored, I got quotes in from other companies to fix his work & nearly everyone has said the same thing, there are so many mistakes the roof will need done again, from membranes installed upside down to the wrong shallow guttering being used plus being WAY overcharged. he talks the talk brilliantly but cannot do the job to a reasonable standard as the Law says they have too, his guarantee is not worth the paper its written on so be warned.
