We carry out uPVC roof lantern repairs in Weymouth and across the DT4 area. Many uPVC roof lanterns have an aluminium core with uPVC cladding and cappings.
What you might be seeing
- Yellowed or brittle end caps
- Cracked cappings or ridge covers
- Green algae along the bars
Common causes we find
UV ageing
uPVC components become brittle and crack after years of sun.
Clip failure
Clip-on cappings can lose their grip and lift.
Roof lanterns in Weymouth
Even in drier areas, one heavy downpour with blocked eaves is enough to overflow a lantern indoors. Clearing the eaves channel is the simplest prevention there is.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
We cover Weymouth as part of Dorset, about 26 miles from Bournemouth.
Neighbouring places we cover include Poole (22 miles), Yeovil (24 miles), Bournemouth (26 miles).
How much should it cost?
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?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. 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.
