Thermal movement

Aluminium moves with temperature; seals and fixings take the strain.

Roof lanterns in Penarth

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.

From Cardiff to Penarth is roughly 3 miles — all part of the South Glamorgan area we cover.

Guide price, per lantern£195–£695 ex VAT£234–£834 inc VAT

Most aluminium roof lantern repairs jobs come in between £195 and £695 ex VAT (£234–£834 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 Wales?

In Wales, 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 (as applied in Wales), so we set out the route in writing first. Listed buildings in Wales need listed building consent from the local planning authority for alterations, with Cadw guidance on historic buildings; check with the council before changing a lantern on a listed property.
