We carry out upstand and kerb repairs in Milford Haven and across the SA73 area. The upstand, or kerb, is the raised frame the lantern sits on.

Is it time for upstand and kerb repairs?
- Roof membrane not lapped up the kerb, or peeling off it
- Ponding water against the kerb after rain
- Cold, damp or mouldy lining around the opening
Common causes we find
Kerb too low
If the kerb doesn't rise enough above the finished roof, water sits against the joint during heavy rain.
Membrane not dressed up
The flat roof covering should run up the kerb and be trimmed or flashed. If it stops short, water gets behind it.
Roof lanterns in Milford Haven
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.
Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.
We cover Milford Haven as part of Dyfed, about 33 miles from Carmarthen.
Neighbouring places we cover include Pembroke Dock (4 miles), Haverfordwest (7 miles), Cardigan (30 miles).
What should you expect to pay in Milford Haven?
Typical range: £395–£1,295 ex VAT, which is £474–£1,554 with 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 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.

Upstand and kerb 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.
Can you add insulation to the kerb?
Yes. Insulated kerbs reduce cold bridging and help with condensation around the opening.

If water has soaked the lining it may need making good after the leak is fixed; we can advise, but internal decorating isn't included unless quoted.
