In Nailsea, as everywhere, flat rooflights fail in the same places as lanterns: the seal to the upstand, the roof junction and the glass unit. Send photos and we'll tell you what we think has failed.

Signs you need flat rooflight and skylight repairs
- Water around the rooflight edge
- Misted glass
- Cracked sealant or a lifted membrane at the upstand
Common causes we find
No fall
Flat glass needs a slight fall to shed water; ponding stresses seals.
Upstand detail
As with lanterns, the membrane must be dressed up and sealed.
Covering Nailsea and nearby
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.
We cover Nailsea as part of Somerset, about 32 miles from Taunton.
Neighbouring places we cover include Portishead (3 miles), Clevedon (4 miles), Bristol (7 miles).
What should you expect to pay in Nailsea?
Most flat rooflight and skylight repairs jobs come in between £195 and £595 ex VAT (£234–£714 including VAT), per rooflight. 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.
