Aluminium lanterns are strong and slim, but they still rely on gaskets, cappings and seals that wear. Send photos from Denbigh (LL16) and we'll tell you which it is — with the price agreed in writing before any work.
Signs you need aluminium roof lantern repairs
- Leaks at bars or ridge
- Misted units
- Corrosion at cut edges or fixings in coastal areas
Common causes we find
Worn gaskets
Gaskets do the weatherproofing; they harden and shrink with age.
Thermal movement
Aluminium moves with temperature; seals and fixings take the strain.
Roof lanterns in Denbigh
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.
We cover Denbigh as part of Clwyd, about 20 miles from Wrexham.
We also cover nearby Ruthin (6 miles), Abergele (10 miles), Rhyl (10 miles).
How much should it cost?
Typical range: £195–£695 ex VAT, which is £234–£834 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?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in Wales. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010 (as applied in Wales); we confirm in writing which route applies before any replacement. 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.
