Why it happens

Hidden water paths

Water can travel along bars, decks and linings before it shows.

More than one fault

Older lanterns often have two or three small failures.

Roof lanterns in Blackheath

Even in drier areas, one heavy downpour with blocked eaves is enough to overflow a lantern indoors. Clearing the eaves channel is the simplest prevention there is.

Across London, many lanterns sit on rear extensions with access only through the house, so we protect floors and plan the work to keep time indoors to a minimum. Parking and any permits are factored into the quote.

We cover Blackheath as part of Greater London, about 7 miles from Westminster.

If you're just outside Blackheath, we also cover Greenwich (1 mile), Catford (2 miles), Eltham (2 miles).

Guide prices for leak investigation and inspection in Blackheath

Do you need permission in England?

In England, like-for-like repairs to a roof lantern don't usually involve building control. A full replacement or a bigger opening is controlled under the Building Regulations 2010, so we set out the route in writing first. Listed buildings need listed building consent from the local council for alterations, and conservation areas can have extra controls; like-for-like repairs are treated differently from changes, so check with the council's conservation officer first.
