Is it time for uPVC roof lantern repairs?

  • Yellowed or brittle end caps
  • Cracked cappings or ridge covers
  • Rattling or whistling in wind

Common causes we find

UV ageing

uPVC components become brittle and crack after years of sun.

Blocked drainage

As with all lanterns, blocked eaves drainage causes overflow.

Covering Johnstone and nearby

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.

From Glasgow to Johnstone is roughly 10 miles — all part of the Glasgow and Clyde area we cover.

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.
