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.

Further from the Village, 1930s semi-detached houses along Forest Road and Hoe Street have concre valleys are found wherever roof slopes meet — between main roofs and extensions, at dormer junctions, and at the intersection of hip roofs.

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.

“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.”
“Called about a small leak in our bay window roof. Turned out to be corroded zinc flashing. They replaced it with lead, dressed it properly, and it has been perfect for two winters now.”
“Our Becontree Estate semi needed a complete re-roof — the 1930s clay tiles were crumbling and the battens underneath were rotten. Four days from start to finish, new concrete tiles, all new battens and felt. Looks brilliant.”
