Orangery lanterns are larger and often sit within a perimeter roof with internal gutters, so leaks can come from the lantern, the perimeter roof or the junction between them. Send photos from Helensburgh (G84) and we'll tell you which it is — with the price agreed in writing before any work.

What you might be seeing
- Leaks at the lantern edge or around the internal pelmet
- Staining on the orangery ceiling
- Rotten or flaking timber on the lantern
Why it happens
Internal gutters
Box gutters around the lantern block and overflow inward.
Timber maintenance
Painted timber orangeries need regular redecoration.
Roof lanterns in Helensburgh
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.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
