In Magherafelt, as everywhere, the upstand, or kerb, is the raised frame the lantern sits on. Send photos and we'll tell you what we think has failed.

What you might be seeing
- Water appearing below the lantern rather than from the glass
- Soft or spongy timber at the base of the lantern
- Cold, damp or mouldy lining around the opening
Why it happens
Kerb too low
If the kerb doesn't rise enough above the finished roof, water sits against the joint during heavy rain.
Membrane not dressed up
The flat roof covering should run up the kerb and be trimmed or flashed. If it stops short, water gets behind it.
About Magherafelt and the BT45 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.
From Derry~Londonderry to Magherafelt is roughly 33 miles — all part of the County Londonderry area we cover.

How much should it cost?
Most upstand and kerb repairs jobs come in between £395 and £1,295 ex VAT (£474–£1,554 including 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 Northern Ireland?
Most lantern repairs in Northern Ireland need no approval at all. Where a job turns into a replacement, the Building Regulations (Northern Ireland) 2012 apply and we confirm how the work will be signed off before we start. 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.
