I very rarely give 5 star reviews but on this occasion the JW Flat Roofing team excelled in every aspect. From the time we got in touch explaining about our leaking flat roof they arrived quickly to do an assessment and then guaranteed we would be dry before Christmas. True to their word they worked in appalling conditions to complete the fit of a completely new roof and all before the Christmas break. The workmanship was superb, they were very pleasant to have around and a special thanks to Clive for his dedicated efforts to complete the job. I cannot recommend them highly enough and we are delighted with the finished product.
