In Watford, as everywhere, the ridge is where the hip bars and glazing bars meet at the top of a lantern, usually under a moulded or pressed end cap. Send photos and we'll tell you what we think has failed.
Signs you need ridge and hip repairs
- A cracked or faded ridge end cap
- Sealant around the ridge cap split or missing
- Staining along the hip bars inside
Why it happens
UV-damaged end caps
Plastic ridge end caps become brittle and crack, especially on south-facing lanterns.
Movement at the junction
Several bars meet at one point and each moves slightly with temperature; the seals at the ridge take the strain.
Covering Watford and nearby
Most inland lantern leaks aren't storm damage; they're usually tired sealant, a lifted capping or blocked eaves drainage. All three are quick to find and fix once you know where to look.

What should you expect to pay in Watford?
Guide price for ridge and hip repairs: £195–£445 ex VAT (£234–£534 inc 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.

Faded or chalky caps are a sign of UV damage. Colour alone isn't a leak, but brittle caps crack, so we check them.
