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 Aberdeen and Aberdeenshire, 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?
Wrong product used
General-purpose or acetoxy silicone can fail early on some frames and coatings. Glazing joints need a low-modulus, compatible sealant.
Patch over patch
Fresh sealant run over old, dirty sealant rarely bonds. It looks fixed for a season and then lets go.
Roof lanterns in Aberdeen and Aberdeenshire
Colder winters mean more frosty mornings, and a roof lantern is often the coldest surface in a warm kitchen — so condensation is as common as genuine leaks. We check which you've got before quoting.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
What should you expect to pay for roof lantern resealing in Aberdeen and Aberdeenshire?
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?
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.
