We put out an enquiry as we had been badly let down by a previous roofer. James contacted us and came that day. He was charming, knowledgeable and reassuring. He started within two days, his work was exemplary - with a great attention to detail - and great value for money. James noticed a few little niggly problems and went above and beyond to fix those too. Wish we had contacted him first. Would thoroughly recommend him.Posted on Google![]()
