Watford Roofing carried out a complete slate roof replacement for us (our roof was over 100 years old). After a wait for them to have time to carry out the work, they arrived on the day they promised and worked every day until the work was complete. All contact from the very beginning was friendly and honest, and I immediately trusted Toby the owner from my initial meeting. The 3 men who carried out the work were fantastic - very hardworking, taking a real pride in the work they do, and respectful around our house and garden (no blaring radio or loud shouty voices) - and very friendly. The work was done on budget, with a small addition requested by the building regs inspector. We had a couple of minor snags that were remedied within 10 days of the main work being completed. The roof looks great from the outside, and the inside too, with all insulation replaced, and also the layer inside the slate being replaced too. All in all, we are very happy with our new roof.
