We carry out flat roof junction and flashing repairs in Stockton-on-Tees and across the TS19 area. The junction where the flat roof covering meets the lantern kerb is a weak point on many extensions.
What you might be seeing
- Leak near the lantern but not from the frame
- Splits, blisters or lifted edges in the roof covering by the kerb
- Ponding on the roof next to the lantern
Common causes we find
Cracked GRP
Fibreglass roofs can crack at the kerb corner where movement concentrates.
Missing trims
Without a trim or flashing to protect the top edge, water gets in behind the membrane.
About Stockton-on-Tees and the TS19 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 Stockton-on-Tees as part of County Durham, about 18 miles from Durham.
Close by, we also cover Billingham (2 miles), Thornaby-on-Tees (3 miles), Middlesbrough (3 miles).
What should you expect to pay in Stockton-on-Tees?
Most flat roof junction and flashing repairs jobs come in between £245 and £695 ex VAT (£294–£834 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 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.
