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!
The lifespan of a roof depends on the materials used and the quality of the installation. A professionally installed slate or tiled roof can often last for several decades when properly maintained. We use quality materials and proven installation methods to maximise the lifespan of every roof we install.
Yes. A slipped tile or minor leak may appear insignificant at first, but over time it can allow water to penetrate the roof structure, leading to timber damage, damp and more costly repairs. Addressing roofing issues early is usually the most cost-effective solution.
Absolutely. Alongside full residential roofs, we also install and repair roofing for garages, extensions, porches, outbuildings and other domestic structures, including modern flat roofing systems.
We focus on providing clear advice, dependable workmanship and roofing solutions that are designed for long-term performance rather than quick fixes. Every project is completed with careful attention to detail, quality materials and a commitment to delivering lasting value for our customers.
