In Peterborough, 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.
What you might be seeing
- Drips near the centre or top of the lantern
- A cracked or faded ridge end cap
- Sealant around the ridge cap split or missing
Common causes we find
Movement at the junction
Several bars meet at one point and each moves slightly with temperature; the seals at the ridge take the strain.
Poor original sealing
Ridge details are fiddly. If the original sealing was rushed, it's often the first place to leak.
Roof lanterns in Peterborough
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.
Peterborough is around 30 miles from Cambridge, and both are within our Cambridgeshire coverage.
We also cover nearby Stamford (11 miles), March (14 miles), Spalding (15 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?
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 Peterborough: questions
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.
Which places near Peterborough do you cover?
As well as Peterborough, we cover nearby Stamford, March, Spalding, Huntingdon and the rest of Cambridgeshire.

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.
