Aluminium lanterns are strong and slim, but they still rely on gaskets, cappings and seals that wear. Send photos from Cleethorpes (DN35) and we'll tell you which it is — with the price agreed in writing before any work.

About Cleethorpes and the DN35 area
Even in drier areas, one heavy downpour with blocked eaves is enough to overflow a lantern indoors. Clearing the eaves channel is the simplest prevention there is.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.

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.
