The junction where the flat roof covering meets the lantern kerb is a weak point on many extensions. Send photos from Dewsbury (WF12) and we'll tell you which it is — with the price agreed in writing before any work.
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
- Missing or loose edge trims and flashings
Common causes we find
Unbonded membrane
EPDM or single-ply that has come away from the kerb lets water run behind it.
Missing trims
Without a trim or flashing to protect the top edge, water gets in behind the membrane.
About Dewsbury and the WF12 area
Damp, mild winters keep moss and algae growing on flat roofs and lantern frames, which holds water against seals and blocks weep slots. Regular clearing makes a real difference in wetter areas.
Urban grime and traffic film dull glass and frames quickly; a clean and seal check makes a tired lantern look and perform much better.
Dewsbury is around 8 miles from Leeds, and both are within our West Yorkshire coverage.
Close by, we also cover Batley (1 mile), Ossett (2 miles), Morley (4 miles).
How much should it cost?
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?
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.
