Questions from Cramlington
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.
Is it worth having solar-control glass in Cramlington?
With the midsummer sun about 58.4° high at noon, roof glass in Cramlington gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
Do I need planning permission for a roof lantern in Cramlington?
Often not, but it depends on the roof, the property and whether it is listed or in a conservation area. Check with your district, borough or unitary council before ordering.
