Rectangular roof lanterns for Risca homes
The classic double-hipped lantern: a ridge, four sloping sides and the most size choice.
In midsummer the noon sun stands about 61.8° high over Risca, so roof glazing gets the full strength of it. That is why solar-control glass is worth considering on larger lanterns here.
- The most size options of any lantern shape
- Intermediate rafters added on longer lengths
- Ridge along the long axis, four glazed slopes

Questions from Risca
Does a longer lantern need extra support?
Long lanterns use intermediate rafters inside the lantern itself. The roof structure around the opening must be designed to carry the lantern's weight; your builder or engineer sizes the trimmers.
Which way should the ridge run?
The ridge runs along the longer side. On a square opening there is no ridge and the lantern becomes a pyramid.
Do I need planning permission for a roof lantern in Risca?
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 Risca?
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.
