  • Missing or loose edge trims and flashings
  • Ponding on the roof next to the lantern

Unbonded membrane

EPDM or single-ply that has come away from the kerb lets water run behind it.

Missing trims

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

Leaf fall from garden trees is the most common cause of eaves overflow on suburban extensions. If your lantern sits near trees, clearing the eaves channel each autumn prevents a lot of drips.

Do you need permission in England?

Most lantern repairs in England need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 apply and we confirm how the work will be signed off before we start. 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.
