Is it time for flat roof junction and flashing repairs?

  • Leak near the lantern but not from the frame
  • Splits, blisters or lifted edges in the roof covering by the kerb

Common causes we find

Cracked GRP

Fibreglass roofs can crack at the kerb corner where movement concentrates.

Missing trims

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

Roof lanterns in Rothesay

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.

We cover Rothesay by arrangement: island work is planned around ferry access, and any travel or access costs are set out in your written quote before you commit.

Guide price for flat roof junction and flashing repairs: £245–£695 ex VAT (£294–£834 inc VAT), per lantern. 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 Scotland?

Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in Scotland. Replacing the whole lantern or enlarging the opening is different and falls under the Building (Scotland) Regulations 2004; we confirm in writing which route applies before any replacement. 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.
