In Dartford, 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.

Ridge end cap and hip bars at the top of an anthracite aluminium roof lantern

What you might be seeing

  • Drips near the centre or top of the lantern
  • A cracked or faded ridge end cap
  • 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.

Covering Dartford and nearby

Even in drier areas, one heavy downpour with blocked eaves is enough to overflow a lantern indoors. Clearing the eaves channel is the simplest prevention there is.

Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.

Dartford is around 18 miles from Maidstone, and both are within our Kent coverage.

Neighbouring places we cover include Bexley (3 miles), Swanley (4 miles), Welling (5 miles).

What should you expect to pay in Dartford?

Guide price, per lantern£195–£445 ex VAT£234–£534 inc VAT

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.
