Flat rooflights fail in the same places as lanterns: the seal to the upstand, the roof junction and the glass unit. Send photos from Canary Wharf (E14) and we'll tell you which it is — with the price agreed in writing before any work.
What you might be seeing
- Water around the rooflight edge
- Misted glass
- Cracked sealant or a lifted membrane at the upstand
Why it happens
No fall
Flat glass needs a slight fall to shed water; ponding stresses seals.
Upstand detail
As with lanterns, the membrane must be dressed up and sealed.
About Canary Wharf and the E14 area
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.
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.
Canary Wharf is around 5 miles from Westminster, and both are within our Greater London coverage.
Close by, we also cover Bow (1 mile), Canning Town (2 miles), Greenwich (2 miles).
Guide prices for flat rooflight and skylight repairs in Canary Wharf
Most flat rooflight and skylight repairs jobs come in between £195 and £595 ex VAT (£234–£714 including VAT), per rooflight. 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.
