Aluminium lanterns are strong and slim, but they still rely on gaskets, cappings and seals that wear. Send photos from Chelsea (SW10) and we'll tell you which it is — with the price agreed in writing before any work.

Is it time for aluminium roof lantern repairs?

What usually causes it?
Thermal movement
Aluminium moves with temperature; seals and fixings take the strain.
Finish damage
Scratches and chips expose bare metal; coastal air speeds up corrosion.

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.
London's extensions are often tight to neighbouring walls and roofs. Where a repair needs access over a neighbour's property, we'll tell you in advance so you can arrange it.

What should you expect to pay in Chelsea?

Do you need permission in England?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. 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.
