We carry out ridge and hip repairs in Harpenden and across the AL5 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
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.
Covering Harpenden and nearby
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.
Harpenden is around 5 miles from St Albans, and both are within our Hertfordshire coverage.
We also cover nearby St Albans (5 miles), Luton (5 miles), Hemel Hempstead (6 miles).
What should you expect to pay in Harpenden?
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?
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.
