We carry out cleaning and maintenance in Belfast and across the BT1 area. Most roof lantern leaks start as small, preventable problems: blocked eaves, a lifted capping, a tired seal.
What you might be seeing
- Dirty glass or green algae on the frame
- You've never had it checked
- The lantern is under trees
What usually causes it?
Debris
Leaves and moss block drainage.
Unnoticed wear
Nobody looks at the roof until it leaks.
About Belfast and the BT1 area
Western and upland parts of the UK get more rain and more wind-driven rain than the east, and that's what finds weak cappings and blocked eaves first. Lanterns here benefit from a check of the bars on the most exposed face and a clear eaves channel before winter.
Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.
If you're just outside Belfast, we also cover Newtownabbey (4 miles), Holywood (5 miles), Lisburn (7 miles).
What should you expect to pay in Belfast?
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 Northern Ireland?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in Northern Ireland. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations (Northern Ireland) 2012; we confirm in writing which route applies before any replacement. Listed buildings in Northern Ireland need listed building consent from the council for alterations; check with the council's planning service before changing a lantern on a listed property.
