Lead, GRP, and dry valley trough repair and replacement. East London’s most common leak source. We cover Hackney, Stratford, Bow, Bethnal Green, Walthamstow, Leyton, Barking, Ilford, Romford, Dagenham, Canary Wharf, Shoreditch, and all surrounding areas.
East London’s diverse housing stock — from Victorian terraces to modern apartments — demands specialist valley repairs expertise. Our team has spent 20+ years mastering every roof type found across the region. Whether you own a Victorian terrace in Hackney, a 1930s semi in Ilford, a Becontree Estate home in Barking, or a warehouse conversion in Shoreditch, we have the skills and materials for the job.
Roof valleys channel water from two converging slopes into a single drainage path. They handle more water flow per square metre than any other part of your roof. In East London, East London’s diverse housing stock includes Victorian terraces across Hackney, Bow, and Bethnal Green, Edwardian villas in Walthamstow and Leyton, 1930s semis stretching through Ilford and Romford, post-war estates in Barking and Dagenham, and modern apartments in Stratford and Canary Wharf. valleys are found wherever roof slopes meet — between main roofs and extensions, at dormer junctions, and at the intersection of hip roofs. When a valley fails, the concentrated water flow causes rapid, serious damage to the roof structure, insulation, and rooms below.
Lead-lined valleys are the traditional and longest-lasting option (50+ years). GRP fibreglass valleys are maintenance-free and theft-proof (25+ years). Dry valley troughs are pre-formed plastic channels that sit under the tiles (20+ years). Mortar valleys (open mortar between tiles) are the oldest method and the most failure-prone. Common issues across East London include nail sickness on Victorian slate roofs, failing concrete tiles on 1930s housing stock, flat roof degradation on post-war estates, lead flashing theft in Tower Hamlets and Hackney, and Thames corridor wind damage to ridge tiles and flashings. We assess the existing valley type, the condition of the timbers beneath, and recommend the most appropriate replacement for your East London property.
If the valley lining has a localised hole or crack, a patch repair may be sufficient. If the lining is generally thin, corroded, or has multiple failure points, full replacement is the only reliable option. We never patch a failing valley just to save money in the short term — it will leak again within months. When we replace a valley, we strip the tiles either side to expose the full valley board, replace any rotten timber, and install a new lining from ridge to eaves with proper overlaps and support.
Hackney, Shoreditch, Bethnal Green: Victorian and Georgian properties dominate. Valley Repairs work here typically involves natural slate, lime mortar, heritage-grade leadwork, and careful attention to conservation area requirements. Lead theft prevention is a major consideration.

“Chimney stack was leaning on our Victorian terrace. They scaffolded, took it down to roofline, rebuilt with matching London stock bricks, and re-flashed in Code 5 lead. Eighteen months later, bone dry.”
“Dormer loft conversion roof in Hackney. The GRP flat top and lead cheeks are perfect. Not a drop of water in eighteen months. They coordinated with our builder seamlessly.”
