Roof Lantern Cleaning and Maintenance Visits

Most roof lantern leaks start as small, preventable problems: blocked eaves, a lifted capping, a tired seal. A maintenance visit clears and cleans the lantern and checks every weak point, so small issues are fixed before they leak.

How often should a roof lantern be maintained?

Once a year suits most lanterns, ideally after leaf fall. Lanterns under trees or in exposed coastal or upland spots may need more. See our maintenance checklist for what to look for between visits — from inside or the ground, never by walking on the roof.
