We carry out flat rooflight and skylight repairs in Milford Haven and across the SA73 area. Flat rooflights fail in the same places as lanterns: the seal to the upstand, the roof junction and the glass unit.

Is it time for flat rooflight and skylight repairs?
- Misted glass
- Ponding on the glass (not enough fall)
- Cracked sealant or a lifted membrane at the upstand
What usually causes it?
No fall
Flat glass needs a slight fall to shed water; ponding stresses seals.
Unit failure
Edge seals fail and the unit mists.
Roof lanterns in Milford Haven
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.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
Milford Haven is around 33 miles from Carmarthen, and both are within our Dyfed coverage.
We also cover nearby Pembroke Dock (4 miles), Haverfordwest (7 miles), Cardigan (30 miles).
What should you expect to pay in Milford Haven?
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 Wales?
Most lantern repairs in Wales need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 (as applied in Wales) apply and we confirm how the work will be signed off before we start. Listed buildings in Wales need listed building consent from the local planning authority for alterations, with Cadw guidance on historic buildings; check with the council before changing a lantern on a listed property.

Flat rooflight and skylight repairs in Milford Haven: questions
Can you repair a lantern someone else installed in Milford Haven?
Yes. We repair lanterns whoever fitted them. If yours is still under the installer's warranty, contact them first so you don't affect it.
Which places near Milford Haven do you cover?
As well as Milford Haven, we cover nearby Pembroke Dock, Haverfordwest, Cardigan, Carmarthen and the rest of Dyfed.
Do you replace walk-on rooflight glass?
Walk-on glass is a specialist structural unit; we can measure and specify a replacement from the right manufacturer.
Can you fix a Velux-style roof window?
Our focus is flat rooflights and lanterns; pitched roof windows are a different trade and we'll say so if that's what you have.
