Questions from Derry
Are flat rooflights cheaper than lanterns?
Usually, size for size. They use one glass unit and a simple frame.
Can I walk on a flat rooflight?
Only if it is a walk-on rooflight designed for foot traffic. Standard rooflights are not designed to be walked on.
Can you fit a roof lantern in Derry?
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.
Do I need planning permission for a roof lantern in Derry?
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.
