Missing trims
Without a trim or flashing to protect the top edge, water gets in behind the membrane.
Roof lanterns in Stirling and Falkirk
Snow and ice sitting at the eaves can block a lantern's drainage and push water back under the glass as it melts. If your lantern leaks after a thaw rather than after rain, tell us — it points to the eaves and kerb.

Repairs are colour-matched as closely as possible, but new topcoat next to weathered topcoat can look slightly different at first.
