Aluminium lanterns are strong and slim, but they still rely on gaskets, cappings and seals that wear. Send photos from Weymouth (DT4) and we'll tell you which it is — with the price agreed in writing before any work.

What you might be seeing

  • Leaks at bars or ridge
  • Misted units
  • Corrosion at cut edges or fixings in coastal areas

What usually causes it?

Worn gaskets

Gaskets do the weatherproofing; they harden and shrink with age.

Finish damage

Scratches and chips expose bare metal; coastal air speeds up corrosion.

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.

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 Weymouth as part of Dorset, about 26 miles from Bournemouth.

How much should it cost?

Guide price, per lantern£195–£695 ex VAT£234–£834 inc VAT

Guide price for aluminium roof lantern repairs: £195–£695 ex VAT (£234–£834 inc 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.
