Missing trims

Without a trim or flashing to protect the top edge, water gets in behind the membrane.

Roof lanterns in County Durham

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.

Do you need permission in England?

In England, 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 2010, so we set out the route in writing first. Listed buildings need listed building consent from the local council for alterations, and conservation areas can have extra controls; like-for-like repairs are treated differently from changes, so check with the council's conservation officer first.

Flat roof junction and flashing repairs in County Durham: questions

Do you repair the whole flat roof?

We repair the area around the lantern. If the wider roof is failing we'll tell you and can quote, but we won't push a new roof if a local repair will do.

Can you repair a GRP roof without it showing?

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