Flat rooflights for Belfast homes
A single near-flat pane on an upstand: minimal, low and discreet.
In midsummer the noon sun stands about 58.8° high over Belfast, so roof glazing gets the full strength of it. That is why solar-control glass is worth considering on larger lanterns here.
- Fixed or electric opening versions
- Very low profile from outside
- Sized to your upstand

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.
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.
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.
