What usually causes it?
More than one fault
Older lanterns often have two or three small failures.
Not the lantern
Sometimes the source is the flat roof, a parapet, a gutter or a wall above.
About Seaford and the BN25 area
Sun and UV do more damage than rain on many lanterns here: brittle ridge caps, chalky finishes and hardened gaskets. They're cheap to replace before they let water in.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.

How much should it cost?
Most leak investigation and inspection jobs come in between £145 and £295 ex VAT (£174–£354 including VAT), per visit. Towers or scaffold, where needed, are priced into the quote. Your fixed price is confirmed in writing before any work starts.
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.
