What usually causes it?

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 Portsmouth and nearby

Drier, sunnier parts of the UK are kinder to seals than the wet west, but strong sun ages sealant, gaskets and plastic end caps, and south- or west-facing lanterns can make rooms very warm. Solar control glass and an opening vent help.

Portsmouth is around 15 miles from Southampton, and both are within our Hampshire coverage.

If you're just outside Portsmouth, we also cover Gosport (2 miles), Fareham (5 miles), Ryde (6 miles).

What should you expect to pay in Portsmouth?

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?

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.

Faded or chalky caps are a sign of UV damage. Colour alone isn't a leak, but brittle caps crack, so we check them.
