In Billingham, as everywhere, flat rooflights fail in the same places as lanterns: the seal to the upstand, the roof junction and the glass unit. Send photos and we'll tell you what we think has failed.

What you might be seeing
- Water around the rooflight edge
- Misted glass
- Ponding on the glass (not enough fall)
Why it happens
No fall
Flat glass needs a slight fall to shed water; ponding stresses seals.
Upstand detail
As with lanterns, the membrane must be dressed up and sealed.
About Billingham and the TS23 area
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.
We cover Billingham as part of County Durham, about 17 miles from Durham.

Guide prices for flat rooflight and skylight repairs in Billingham
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?
Most lantern repairs in England need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 apply and we confirm how the work will be signed off before we start. 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.
