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![]()

This company is definitely trustworthy, I had them to do a full roof for me plus all faschias and gutters and had no problems at all, turned up on time every day, whatever the weather, cleaned up after themselves every day and were honestly the most politest and respectful lads you could wish for and also gave us the best quote, not necessarily the cheapest but we certainly were not ripped off! credit where it's due!
