Many uPVC roof lanterns have an aluminium core with uPVC cladding and cappings. Send photos from South Croydon (CR0) and we'll tell you which it is — with the price agreed in writing before any work.
What you might be seeing
- Yellowed or brittle end caps
- Cracked cappings or ridge covers
- Green algae along the bars
Why it happens
UV ageing
uPVC components become brittle and crack after years of sun.
Blocked drainage
As with all lanterns, blocked eaves drainage causes overflow.
Roof lanterns in South Croydon
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.
South Croydon is around 10 miles from Westminster, and both are within our Greater London coverage.
Close by, we also cover Croydon (1 mile), Purley (2 miles), Wallington (3 miles).
How much should it cost?
Guide price for uPVC roof lantern repairs: £175–£595 ex VAT (£210–£714 inc VAT), per lantern. 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?
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.
