We carry out roof lantern replacement in Bow and across the E3 area. We're repair-first, but some lanterns are past it: distorted frames, rot through the main bars, or most of the glass failed.

Signs you need roof lantern replacement
- Distorted or sagging frame
- Rotten timber throughout
- Repeated leaks after previous repairs
Why it happens
Age
Older lanterns can't be brought up to modern performance with repairs alone.
Structural damage
Impact or movement distorts the frame.
Roof lanterns in Bow
Drier, sunnier parts of the UK are kinder to seals than the wet west, but strong sun ages sealant, gaskets and plastic end caps, and south- or west-facing lanterns can make rooms very warm. Solar control glass and an opening vent help.
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.
We cover Bow as part of Greater London, about 5 miles from Westminster.
We also cover nearby Stratford (1 mile), Canary Wharf (1 mile), Canning Town (2 miles).
Guide prices for roof lantern replacement in Bow
Guide price for roof lantern replacement: £1,995–£4,995 ex VAT (£2,394–£5,994 inc VAT), supplied and fitted. 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?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. 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.
