Flat rooflights fail in the same places as lanterns: the seal to the upstand, the roof junction and the glass unit. Send photos from Ely (CB7) and we'll tell you which it is — with the price agreed in writing before any work.
What you might be seeing
- Water around the rooflight edge
- Ponding on the glass (not enough fall)
- Cracked sealant or a lifted membrane at the upstand
Common causes we find
Upstand detail
As with lanterns, the membrane must be dressed up and sealed.
Unit failure
Edge seals fail and the unit mists.
About Ely and the CB7 area
Sun and UV do more damage than rain on many lanterns here: brittle ridge caps, chalky finishes and hardened gaskets. They're cheap to replace before they let water in.

Guide prices for flat rooflight and skylight repairs in Ely
Most flat rooflight and skylight repairs jobs come in between £195 and £595 ex VAT (£234–£714 including 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.
