Questions from Caerphilly
Who makes the upstand weatherproof?
Your roofer, by dressing the roof membrane up the outside of the upstand. The lantern then sits over it.
Do I need an upstand for a roof lantern?
Yes. Lanterns are designed to sit on an upstand, never directly on the roof deck.
Who checks building regulations for a lantern in Caerphilly?
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.

With the midsummer sun about 61.9° high at noon, roof glass in Caerphilly gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
