Many uPVC roof lanterns have an aluminium core with uPVC cladding and cappings. Send photos from Kendal (LA9) and we'll tell you which it is — with the price agreed in writing before any work.

Roof lanterns in Kendal
Wind-driven rain is the real test of a roof lantern, and the wetter west sees plenty of it. Leaks that appear only in a storm from one direction usually point to the cappings or eaves on that face — a useful clue when you send us photos.
Kendal is around 40 miles from Carlisle, and both are within our Cumbria coverage.

What should you expect to pay in Kendal?
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?
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.
