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 Hatfield (AL10) and we'll tell you which it is — with the price agreed in writing before any work.

Signs you need ridge and hip repairs
- A cracked or faded ridge end cap
- Sealant around the ridge cap split or missing
- 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.
Roof lanterns in Hatfield
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.
Hatfield is around 5 miles from St Albans, and both are within our Hertfordshire coverage.
Close by, we also cover Welwyn Garden City (3 miles), St Albans (5 miles), Potters Bar (5 miles).
How much should it cost?
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?
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.
