In St Albans, 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

  • Drips near the centre or top of the lantern
  • Sealant around the ridge cap split or missing
  • Staining along the hip bars inside

What usually causes it?

UV-damaged end caps

Plastic ridge end caps become brittle and crack, especially on south-facing lanterns.

Poor original sealing

Ridge details are fiddly. If the original sealing was rushed, it's often the first place to leak.

Roof lanterns in St Albans

Lanterns in central England see a bit of everything — summer sun that ages seals and end caps, autumn leaf fall that blocks eaves, and frosty mornings that bring condensation. A yearly check covers all three.

We also cover nearby Harpenden (5 miles), Hatfield (5 miles), Hemel Hempstead (5 miles).

What should you expect to pay in St Albans?

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

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?

Most lantern repairs in England need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 apply and we confirm how the work will be signed off before we start. 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.

Ridge and hip repairs in St Albans: questions

How do I get a price for ridge and hip repairs in St Albans?

Send a few photos of the lantern and the problem, with your St Albans postcode. We'll reply with a guide price and tell you whether a visit is needed before we can fix the price.

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.

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.

Can you replace just the ridge cap?

Yes, if a compatible cap is available and the seals underneath are sound.
