In Dumfries, as everywhere, the junction where the flat roof covering meets the lantern kerb is a weak point on many extensions. Send photos and we'll tell you what we think has failed.

Signs you need 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
  • Ponding on the roof next to the lantern

Why it happens

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.

Covering Dumfries and nearby

Western and upland parts of the UK get more rain and more wind-driven rain than the east, and that's what finds weak cappings and blocked eaves first. Lanterns here benefit from a check of the bars on the most exposed face and a clear eaves channel before winter.

Neighbouring places we cover include Lockerbie (11 miles), Annan (15 miles), Castle Douglas (15 miles).

What should you expect to pay in Dumfries?

Guide price, per lantern£245–£695 ex VAT£294–£834 inc VAT

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.
