We recently hired Darren Hennessy Roofing to replace a rotten & leaky flat roof, and we are extremely pleased with the entire experience. We had tried so many other roofers over a few years. Darren and his team were professional, reliable, and highly skilled from start to finish. They quickly identified the issues with the old roof and explained the best solution clearly and honestly. Their expertise and attention to detail gave us great confidence throughout the project. The work was completed to an excellent standard, with real care taken at every stage. The new flat roof looks superb, and the quality of workmanship is evident. The team was efficient, tidy, and respectful, making the whole process as smooth and stress-free as possible. We have had no issues since. We would highly recommend Darren Hennessy Roofing to anyone looking for dependable service, expert advice, and top-quality roofing work. Thanks Darren

Darren was the first to respond to my request for a quote. He came himself the next day, quickly assessed what the issue was, gave me a quote that was exactly what I paid at the end of the job (no unexpected extras or additions as sometimes happens with quotes). He said it would be approximately 2 to 3 weeks before he could start and that’s exactly when the work was done - no chasing and no hassle. The team were very efficient, turned up early, worked hard, explained what they were doing and cleared everything up at the end. Leak is gone and really happy with the work and the service.

We recently contacted Darren of D. Hennessy Roofing about an ongoing leak in our kitchen roof. He provided a very competitive quote. We had received an outrageous quote from someone else. Darren and Peter identified the source of the leak and did a very professional and thorough job, removing all damaged materials and installing new breathable felt membrane, new lead flashing, new lead soakers and replaced damaged tiles and provided full transparency and reassurance with photos of the damaged roof and damaged materials at the start of job and photos of all new materials fitted. Darren provides excellent value for money, work of a very high standard and uses top quality materials. He is very accessible at all times, 100% honest and trustworthy, and gives total peace of mind to the customer from start to finish. I would absolutely recommend Darren for all your roofing requirements big and small.
