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 from Stratford (E15) and we'll tell you which it is — with the price agreed in writing before any work.
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.
About Stratford and the E15 area
Sun and UV do more damage than rain on many lanterns here: brittle ridge caps, chalky finishes and hardened gaskets. They're cheap to replace before they let water in.
London's extensions are often tight to neighbouring walls and roofs. Where a repair needs access over a neighbour's property, we'll tell you in advance so you can arrange it.

What should you expect to pay in Stratford?
Typical range: £195–£445 ex VAT, which is £234–£534 with 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.

Ridge and hip repairs in Stratford: questions
How do I get a price for ridge and hip repairs in Stratford?
Send a few photos of the lantern and the problem, with your Stratford 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.
