In Broadstairs, as everywhere, many uPVC roof lanterns have an aluminium core with uPVC cladding and cappings. Send photos and we'll tell you what we think has failed.

What you might be seeing
- Yellowed or brittle end caps
- Cracked cappings or ridge covers
- Leaks at the ridge or eaves
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.
About Broadstairs and the CT10 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.
Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.
Broadstairs is around 40 miles from Maidstone, and both are within our Kent coverage.

Guide prices for uPVC roof lantern repairs in Broadstairs
Typical range: £175–£595 ex VAT, which is £210–£714 with 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?
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.
