Questions from Belfast
How long does replacement take on site?
For a like-for-like swap on a sound kerb, often a day. Kerb or roof repairs add time.
Will a new lantern be warmer?
A modern double glazed lantern with a thermally broken frame loses far less heat than polycarbonate.
Do I need planning permission for a roof lantern in Belfast?
Often not, but it depends on the roof, the property and whether it is listed or in a conservation area. Check with your district council before ordering.
Can you fit a roof lantern in Belfast?
We can quote for fitting where we have cover. Send your postcode and photos of the roof and kerb, and we will confirm before quoting.
