Questions from Cardiff
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.
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 planning permission for a roof lantern in Cardiff?
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.
Can you fit a roof lantern in Cardiff?
We can quote for fitting where we have cover. Send your postcode and photos of the roof and kerb, and we will confirm before quoting.
