Had the original lead valley on our lovely 100 year old house replaced,under the advice of a 'roofer', with a GRP (fibreglass version) when we first moved in. Years later, we discovered dampness in a bedroom cupboard and through further investigation found the valley had been leaking, through the floor and onto the ceiling below. Called John Couzens for advice and asked for a quote for this work and for re-doing the whole roof at the same time. Agreed a date and the work began. John and his team stripped the roof of tiles and battens and installed insulation to the inaccessible parts of the roof space. They then removed the existing cracked valley and rotten timbers. The team then felt/battened and re-tiled the roof as well as re-building the wooden valley structure prior to installing a beautiful lead version. The project was finished on time (give or take a few days due to weather and supplies being delayed) and the quality and detailing is truly outstanding. John and his team were friendly, approachable and knowledgable throughout. I would heartily recommend.
