Newly trimmed flat roof junction and flashing tape around a roof lantern kerb

What you might be seeing

  • Splits, blisters or lifted edges in the roof covering by the kerb
  • Missing or loose edge trims and flashings
  • Ponding on the roof next to the lantern

Common causes we find

Unbonded membrane

EPDM or single-ply that has come away from the kerb lets water run behind it.

Cracked GRP

Fibreglass roofs can crack at the kerb corner where movement concentrates.

Roof lanterns in Glasgow

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.

Urban grime and traffic film dull glass and frames quickly; a clean and seal check makes a tired lantern look and perform much better.

We also cover nearby Rutherglen (3 miles), Bishopbriggs (3 miles), Bearsden (5 miles).

What should you expect to pay in Glasgow?

Guide price, per lantern£245–£695 ex VAT£294–£834 inc VAT

Typical range: £245–£695 ex VAT, which is £294–£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 Scotland?

In Scotland, like-for-like repairs to a roof lantern don't usually involve building control. A full replacement or a bigger opening is controlled under the Building (Scotland) Regulations 2004, so we set out the route in writing first. Listed buildings in Scotland need listed building consent from the planning authority for alterations, with Historic Environment Scotland guidance; check before changing a lantern on a listed property.
