Many uPVC roof lanterns have an aluminium core with uPVC cladding and cappings. Send photos from Archway (N19) and we'll tell you which it is — with the price agreed in writing before any work.

What you might be seeing
- Cracked cappings or ridge covers
- Green algae along the bars
- Leaks at the ridge or eaves
Why it happens
UV ageing
uPVC components become brittle and crack after years of sun.
Clip failure
Clip-on cappings can lose their grip and lift.
Covering Archway and nearby
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.

Guide prices for uPVC roof lantern repairs in Archway
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?
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.
