Many uPVC roof lanterns have an aluminium core with uPVC cladding and cappings. Send photos from Dartford (DA1) 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
- Rattling or whistling in wind
- Leaks at the ridge or eaves
Common causes we find
Clip failure
Clip-on cappings can lose their grip and lift.
Blocked drainage
As with all lanterns, blocked eaves drainage causes overflow.
Covering Dartford and nearby
Sun and UV do more damage than rain on many lanterns here: brittle ridge caps, chalky finishes and hardened gaskets. They're cheap to replace before they let water in.
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.
Dartford is around 18 miles from Maidstone, and both are within our Kent coverage.

What should you expect to pay in Dartford?
Most uPVC roof lantern repairs jobs come in between £175 and £595 ex VAT (£210–£714 including 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.
