This company is really exceptional. They are honest, prompt and masters at their craft. Not only did they do a brilliant job at re-roofing my mother's house (over 15 years ago now) but furthermore did an amazing job on a leaking dormer which literally turned out to be a work of art once completed. The flashing and tile application was above and beyond what I expected. Since then, they have been always supportive and absolute gents when it came to a few instances of storm damage.... I'd put 6 stars if I were able!
Dan and James reroofed my bungalow and I am really pleased with the results. I've already received a compliment from a neighbour about the roof finish and look, complimenting me on the scalloping detail on the front, thinking it was my idea. I corrected him and told him it was Dan's and how pleased I am with it. It adds a really nice touch and subtle, individualised detail. Dan and James were polite, helpful and always swept and cleaned up after themselves. Communication with Danny has also made it an easy and stress free process. I highly recommend.
Very pleased with the work done by Paul and his team. This was quite a complicated project, involving the reslating of a large Victorian roof with a mixture of reclaimed Delabole and Welsh slate. Despite some setbacks along the way, the roofing gang headed by Danny handled everything with skill and good humour. 2 years on, the roof still looks great, and the after sales service is impressive, too.
Great firm. The guys are so diligent, polite and excellent workers. Always cleaned up at the end of each day. Great job. Would recommend.
