Roofer in West Hampstead — Leaks, Tiles, Flat Roofs & Flashings

Staining indoors may come from the roof, a parapet, plumbing or condensation, so we trace the source before a repair is priced.

Tell us where water appears, when it shows, for instance in heavy rain or wind, and any past repairs. Photograph the stain, the gutter line and the roof from the street or a rear window. Do not climb onto the roof.

A Victorian or Edwardian terrace may drain through a concealed valley gutter behind a parapet, where debris and failed linings can go unnoticed. Bays can carry their own small roofs and flashings.

Slate, tile and flashing repairs are scoped once the roof form, covering and safe access are known. Like-for-like repairs and a full re-cover are different written packages, and a fragile roof may need a survey before a fixed price.

Like-for-like repair is generally maintenance, but new materials, rooflights or altered parapets may need planning input. Camden’s West End Green appraisal lists roof changes among the pressures on local character; whether it applies depends on the exact address.

Mansion blocks bring shared roofs that the managing agent may control, and in a flat the roof may belong to the freeholder. Tell us who manages the building.

Roof access can need managing-agent keys and a permit to work. Arrange any freeholder approval before work starts, and attach any licence to alter, working-hours note or previous roof survey you already hold.

Rear roofs on terraces may only be reachable through the house or a neighbour’s garden. A scaffold or tower on the public highway needs a licence from the authority responsible for that road, which on a red route is Transport for London.

Railway corridors and West End Lane traffic affect when materials can arrive, so tell us about rear access and where a vehicle can stop.
