Missing trims

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

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.

Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.

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 Kent: 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.

Which towns in Kent do you cover?

All of Kent, including Maidstone, Gillingham, Chatham, Tunbridge Wells, Folkestone, Margate. Rural and remote addresses are covered by arrangement.
