We carry out ridge and hip repairs in Lisburn and across the BT27 area. 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.

Signs you need ridge and hip repairs

  • Drips near the centre or top of the lantern
  • 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.

Roof lanterns in Lisburn

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.

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.

Do you need permission in Northern Ireland?

Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in Northern Ireland. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations (Northern Ireland) 2012; we confirm in writing which route applies before any replacement. Listed buildings in Northern Ireland need listed building consent from the council for alterations; check with the council's planning service before changing a lantern on a listed property.

Do you need to visit to price ridge and hip repairs?

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.

What does a ridge repair cost?

Usually £195–£445 ex VAT for a standard lantern, confirmed in writing before work starts.

My ridge cap is a different colour from the frame — does that matter?

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