Flat rooflights fail in the same places as lanterns: the seal to the upstand, the roof junction and the glass unit. We carry out flat rooflight and skylight repairs across County Durham, with a guide price from your photos and a fixed price in writing before any work starts.
Signs you need flat rooflight and skylight repairs
- Misted glass
- Ponding on the glass (not enough fall)
- Cracked sealant or a lifted membrane at the upstand
What usually causes it?
No fall
Flat glass needs a slight fall to shed water; ponding stresses seals.
Unit failure
Edge seals fail and the unit mists.
Roof lanterns in County Durham
Freeze-thaw cycles open up tired sealant and gaskets faster than mild weather does. A spring check after a hard winter catches most problems before they leak.

What should you expect to pay for flat rooflight and skylight repairs in County Durham?
Typical range: £195–£595 ex VAT, which is £234–£714 with VAT, per rooflight. 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 England?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. Listed buildings need listed building consent from the local council for alterations, and conservation areas can have extra controls; like-for-like repairs are treated differently from changes, so check with the council's conservation officer first.
