We carry out flat rooflight and skylight repairs in Willesden and across the NW10 area. Flat rooflights fail in the same places as lanterns: the seal to the upstand, the roof junction and the glass unit.

Is it time for flat rooflight and skylight repairs?
- Water around the rooflight edge
- Misted glass
- Ponding on the glass (not enough fall)
Common causes we find
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.
Roof lanterns in Willesden
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.
Willesden is around 5 miles from Westminster, and both are within our Greater London coverage.
If you're just outside Willesden, we also cover Cricklewood (2 miles), Notting Hill (2 miles), Shepherds Bush (2 miles).
What should you expect to pay in Willesden?
Guide price for flat rooflight and skylight repairs: £195–£595 ex VAT (£234–£714 inc 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.
