Questions from Belfast
What height should my upstand be?
High enough to keep water away from the lantern seal, commonly at least 150 mm above the finished roof surface. Follow the instructions for your chosen range.
Do I need an upstand for a roof lantern?
Yes. Lanterns are designed to sit on an upstand, never directly on the roof deck.
How quickly can I get a roof lantern in Belfast?
Stock sizes are typically ready in 5–10 working days, made-to-measure in 3–4 weeks, plus delivery. Your quote gives the date for BT1.
Do I need planning permission for a roof lantern in Belfast?
Often not, but it depends on the roof, the property and whether it is listed or in a conservation area. Check with your district council before ordering.
