We carry out commercial roof lantern repairs in St Austell and across the PL25 area. Commercial lanterns and atrium rooflights fail in the same ways as domestic ones, but access, safety and disruption matter more.
What you might be seeing

- Insurance or landlord requirement for a report
- Managed buildings with planned maintenance needs
Common causes we find
Scale

About St Austell and the PL25 area
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.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
From Truro to St Austell is roughly 13 miles — all part of the Cornwall area we cover.
We also cover nearby Bodmin (9 miles), Truro (13 miles), Newquay (14 miles).
How much should it cost?
Guide price for commercial roof lantern repairs: £495–£2,995 ex VAT (£594–£3,594 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?
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.
