What usually causes it?
UV ageing
uPVC components become brittle and crack after years of sun.
Blocked drainage
As with all lanterns, blocked eaves drainage causes overflow.
About Penzance and the TR18 area
Western and upland parts of the UK get more rain and more wind-driven rain than the east, and that's what finds weak cappings and blocked eaves first. Lanterns here benefit from a check of the bars on the most exposed face and a clear eaves channel before winter.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
Penzance is around 24 miles from Truro, and both are within our Cornwall coverage.

Guide prices for uPVC roof lantern repairs in Penzance
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?
Most lantern repairs in England need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 apply and we confirm how the work will be signed off before we start. 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.
