Roof lantern leak repairs in Bristol

A roof lantern leak is almost always a failed seal, a lifted capping, blocked eaves drainage or a problem where the kerb meets the flat roof — not a failed lantern. We carry out roof lantern leak repairs across Bristol, with a guide price from your photos and a fixed price in writing before any work starts.

What usually causes it?

Lifted or misaligned cappings

Top cappings clip or screw over each glazing bar. If one has lifted, been knocked or was never seated, rain gets straight under it.

The kerb or roof junction

If the flat roof membrane isn't dressed high enough up the kerb, or the kerb has no fall, water sits against the joint and finds its way in under the lantern.

Wind-driven rain is the real test of a roof lantern, and the wetter west sees plenty of it. Leaks that appear only in a storm from one direction usually point to the cappings or eaves on that face — a useful clue when you send us photos.

In built-up areas, access is often the hardest part of the job — through the house, over a neighbour's roof, or with parking restrictions. We plan access in advance and price any tower or scaffold into the quote.

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.

Roof lantern leak repairs in Bristol: questions

Can you fix the leak in the rain?

We can make the lantern safe in wet weather, but sealants and tapes need a dry, clean surface to bond, so permanent repairs are done in a dry window.

Do I need to be home?

If we need to water-test or check the inside of the lantern, yes. Exterior-only work can sometimes be done with access arranged in advance.

Which towns in Bristol do you cover?

All of Bristol, including Bristol. Rural and remote addresses are covered by arrangement.
