Most roof lantern leaks start as small, preventable problems: blocked eaves, a lifted capping, a tired seal. Send photos from Great Yarmouth (NR30) and we'll tell you which it is — with the price agreed in writing before any work.

Is it time for cleaning and maintenance?
- Dirty glass or green algae on the frame
- Leaves or moss at the eaves
- You've never had it checked
What usually causes it?
Algae and dirt
Hold moisture against seals and spoil the view.
Unnoticed wear
Nobody looks at the roof until it leaks.
Covering Great Yarmouth 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.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.

How much should it cost?
Guide price for cleaning and maintenance: £95–£245 ex VAT (£114–£294 inc VAT), per visit. 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.
