Replacement roof lanterns for Penarth homes
Swap a tired, leaking or polycarbonate lantern for modern double glazing.
In midsummer the noon sun stands about 62.0° high over Penarth, so roof glazing gets the full strength of it. That is why solar-control glass is worth considering on larger lanterns here.
- Reuse the kerb if sound and to size
- Warmer, quieter, brighter
- Replace old polycarbonate with glass

Questions from Penarth
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.
Can I replace polycarbonate panels with glass?
Usually not in the old frame: glass is much heavier than polycarbonate and the frame was not designed for it. Replacing the whole lantern is the safer route.
Do I need planning permission for a roof lantern in Penarth?
Often not, but it depends on the roof, the property and whether it is listed or in a conservation area. Check with your county or county borough council before ordering.
Who checks building regulations for a lantern in Penarth?
Your local authority building control team. For a lantern in a new extension it forms part of the extension's approval; replacements in existing homes have their own rules.
