Why it happens
Hidden water paths
Water can travel along bars, decks and linings before it shows.
Not the lantern
Sometimes the source is the flat roof, a parapet, a gutter or a wall above.
Roof lanterns in Warrington
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.
We cover Warrington as part of Cheshire, about 19 miles from Chester.
Neighbouring places we cover include Newton-le-Willows (4 miles), Golborne (6 miles), Widnes (7 miles).
How much should it cost?
Most leak investigation and inspection jobs come in between £145 and £295 ex VAT (£174–£354 including VAT), per visit. 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.

Leak investigation and inspection in Warrington: questions
Do you need to visit to price leak investigation and inspection?
Not always. Clear photos are often enough for a guide price. Where the cause isn't obvious, a visit to inspect and water-test is charged from £145 ex VAT, confirmed before we come.
Can you repair a lantern someone else installed in Warrington?
Yes. We repair lanterns whoever fitted them. If yours is still under the installer's warranty, contact them first so you don't affect it.
Is the visit cost deducted from the repair?
Ask when you book — we'll confirm in writing how the visit is charged if you go ahead with the repair.
Do you provide a report?
Yes, with photos and findings, which is useful for landlords, insurers and disputes with installers.
