Signs you need flat roof junction and flashing repairs

  • Splits, blisters or lifted edges in the roof covering by the kerb
  • Missing or loose edge trims and flashings
  • Ponding on the roof next to the lantern

Why it happens

Unbonded membrane

EPDM or single-ply that has come away from the kerb lets water run behind it.

Missing trims

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

Roof lanterns in Dunoon

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.

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.

From Oban to Dunoon is roughly 39 miles — all part of the Argyll and Bute area we cover.

Do you need permission in Scotland?

In Scotland, 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 (Scotland) Regulations 2004, so we set out the route in writing first. Listed buildings in Scotland need listed building consent from the planning authority for alterations, with Historic Environment Scotland guidance; check before changing a lantern on a listed property.

Flat roof junction and flashing repairs in Dunoon: questions

How do I get a price for flat roof junction and flashing repairs in Dunoon?

Send a few photos of the lantern and the problem, with your Dunoon postcode. We'll reply with a guide price and tell you whether a visit is needed before we can fix the price.

Can you repair a lantern someone else installed in Dunoon?

Yes. We repair lanterns whoever fitted them. If yours is still under the installer's warranty, contact them first so you don't affect it.

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.
