In Greenwich, as everywhere, most roof lantern leaks start as small, preventable problems: blocked eaves, a lifted capping, a tired seal. Send photos and we'll tell you what we think has failed.

Is it time for cleaning and maintenance?
- Dirty glass or green algae on the frame
- Leaves or moss at the eaves
- The lantern is under trees
What usually causes it?
Debris
Leaves and moss block drainage.
Unnoticed wear
Nobody looks at the roof until it leaks.

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.
London's extensions are often tight to neighbouring walls and roofs. Where a repair needs access over a neighbour's property, we'll tell you in advance so you can arrange it.

Guide prices for cleaning and maintenance in Greenwich
Most cleaning and maintenance jobs come in between £95 and £245 ex VAT (£114–£294 including VAT), per visit. Towers or scaffold, where needed, are priced into the quote. Your fixed price is confirmed in writing before any work starts.
Do you need permission in England?
Most lantern repairs in England need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 apply and we confirm how the work will be signed off before we start. 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.
