We carry out cleaning and maintenance in Downpatrick and across the BT30 area. Most roof lantern leaks start as small, preventable problems: blocked eaves, a lifted capping, a tired seal.

Signs you need cleaning and maintenance
- Dirty glass or green algae on the frame
- Leaves or moss at the eaves
- You've never had it checked
What usually causes it?
Algae and dirt
Hold moisture against seals and spoil the view.
Unnoticed wear
Nobody looks at the roof until it leaks.
About Downpatrick and the BT30 area
Damp, mild winters keep moss and algae growing on flat roofs and lantern frames, which holds water against seals and blocks weep slots. Regular clearing makes a real difference in wetter areas.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.

What should you expect to pay in Downpatrick?

Do you need permission in Northern Ireland?
In Northern Ireland, 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 Regulations (Northern Ireland) 2012, so we set out the route in writing first. Listed buildings in Northern Ireland need listed building consent from the council for alterations; check with the council's planning service before changing a lantern on a listed property.
