Questions from Lisburn
Do flat rooflights leak?
They should not, provided they are installed on a properly flashed upstand with the right fall and the seals are maintained.
Are flat rooflights cheaper than lanterns?
Usually, size for size. They use one glass unit and a simple frame.
Is it worth having solar-control glass in Lisburn?
With the midsummer sun about 58.9° high at noon, roof glass in Lisburn gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
Do I need planning permission for a roof lantern in Lisburn?
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.
