Resealing is the planned, whole-lantern version of a leak repair: we cut out the old, failed sealant, clean every joint back to a sound surface and reseal the cappings, ridge and eaves with materials that suit the frame. We carry out roof lantern resealing across Dumfries and Galloway, with a guide price from your photos and a fixed price in writing before any work starts.
Signs you need roof lantern resealing
- Cracked, split or shrunken sealant along the bars
- Black mould or dirt lines trapped in old silicone
- Sealant applied over sealant from previous patch repairs
What usually causes it?
Sealant past its life
Exposed sealant on a roof takes UV, frost and constant expansion and contraction. It hardens, loses grip and pulls away from the glass.
Wrong product used
General-purpose or acetoxy silicone can fail early on some frames and coatings. Glazing joints need a low-modulus, compatible sealant.
Roof lanterns in Dumfries and Galloway
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.
What should you expect to pay for roof lantern resealing in Dumfries and Galloway?
Most roof lantern resealing jobs come in between £245 and £495 ex VAT (£294–£594 including 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?
Most lantern repairs in Scotland need no approval at all. Where a job turns into a replacement, the Building (Scotland) Regulations 2004 apply and we confirm how the work will be signed off before we start. 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.
