We carry out roof lantern replacement in Lowestoft and across the NR32 area. We're repair-first, but some lanterns are past it: distorted frames, rot through the main bars, or most of the glass failed.

What you might be seeing
- Distorted or sagging frame
- Rotten timber throughout
- Repeated leaks after previous repairs
What usually causes it?
Age
Older lanterns can't be brought up to modern performance with repairs alone.
Rot
Timber lanterns left unmaintained.
Roof lanterns in Lowestoft
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.
We cover Lowestoft as part of Suffolk, about 38 miles from Ipswich.
Close by, we also cover Great Yarmouth (9 miles), Norwich (22 miles), Stowmarket (37 miles).
How much should it cost?
Guide price for roof lantern replacement: £1,995–£4,995 ex VAT (£2,394–£5,994 inc VAT), supplied and fitted. 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.
