The junction where the flat roof covering meets the lantern kerb is a weak point on many extensions. Send photos from Widnes (WA8) and we'll tell you which it is — with the price agreed in writing before any work.
Is it time for flat roof junction and flashing repairs?
- Splits, blisters or lifted edges in the roof covering by the kerb
- Missing or loose edge trims and flashings

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.
Roof lanterns in Widnes
Western and upland parts of the UK get more rain and more wind-driven rain than the east, and that's what finds weak cappings and blocked eaves first. Lanterns here benefit from a check of the bars on the most exposed face and a clear eaves channel before winter.
Widnes is around 14 miles from Chester, and both are within our Cheshire coverage.
If you're just outside Widnes, we also cover Runcorn (1 mile), Halewood (4 miles), Prescot (5 miles).
How much should it cost?
Typical range: £245–£695 ex VAT, which is £294–£834 with 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?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. 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.
