In Lisburn, as everywhere, timber roof lanterns are beautiful and repairable, but they need sound paint, sound beads and dry timber. Send photos and we'll tell you what we think has failed.
What you might be seeing
- Dark staining or black lines along joints
- Putty or beads cracking and lifting
- Leaks at bar joints
What usually causes it?
Paint failure
Once the paint film breaks, water gets into the end grain and joints.
Water trapped by beads
Glazing beads and putty can trap water against the timber if their seals fail.
About Lisburn and the BT27 area
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.
