In Gravesend, 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
Common causes we find
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.
About Gravesend and the DA12 area
Drier, sunnier parts of the UK are kinder to seals than the wet west, but strong sun ages sealant, gaskets and plastic end caps, and south- or west-facing lanterns can make rooms very warm. Solar control glass and an opening vent help.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
Gravesend is around 14 miles from Maidstone, and both are within our Kent coverage.
We also cover nearby Grays (3 miles), Strood (6 miles), South Ockendon (6 miles).
How much should it cost?
Most ridge and hip repairs jobs come in between £195 and £445 ex VAT (£234–£534 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?
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.

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