In Sudbury, as everywhere, many uPVC roof lanterns have an aluminium core with uPVC cladding and cappings. Send photos and we'll tell you what we think has failed.

What you might be seeing
- Cracked cappings or ridge covers
- Green algae along the bars
- Rattling or whistling in wind
Why it happens
UV ageing
uPVC components become brittle and crack after years of sun.
Blocked drainage
As with all lanterns, blocked eaves drainage causes overflow.
About Sudbury and the CO10 area
Drier, sunnier parts of the UK are kinder to seals than the wet west, but strong sun ages sealant, gaskets and plastic end caps, and south- or west-facing lanterns can make rooms very warm. Solar control glass and an opening vent help.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.

Guide prices for uPVC roof lantern repairs in Sudbury
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.
