Questions from Mitcham
Who makes the upstand weatherproof?
Your roofer, by dressing the roof membrane up the outside of the upstand. The lantern then sits over it.
Can I order a lantern before the upstand is built?
Yes, if you build the upstand to the lantern's stated external size. Many people order the lantern and upstand together so they match.
Is it worth having solar-control glass in Mitcham?
With the midsummer sun about 62.0° high at noon, roof glass in Mitcham gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
