Flat rooflights fail in the same places as lanterns: the seal to the upstand, the roof junction and the glass unit. Send photos from Ilkeston (DE7) and we'll tell you which it is — with the price agreed in writing before any work.
Signs you need flat rooflight and skylight repairs
- Water around the rooflight edge
- 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.
About Ilkeston and the DE7 area
Snow and ice sitting at the eaves can block a lantern's drainage and push water back under the glass as it melts. If your lantern leaks after a thaw rather than after rain, tell us — it points to the eaves and kerb.
From Derby to Ilkeston is roughly 8 miles — all part of the Derbyshire area we cover.
If you're just outside Ilkeston, we also cover Heanor (4 miles), Long Eaton (5 miles), Ripley (6 miles).
How much should it cost?
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?
In England, 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 Regulations 2010, so we set out the route in writing first. 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.
