Square roof lanterns in County Down: questions
Will a square lantern leak at the top?
It should not when it is correctly installed and maintained. The apex is factory-designed to shed water; leaks usually come from the upstand or roof membrane rather than the lantern itself, which is why the upstand detail matters.
Can I have an opening vent in a pyramid lantern?
Some ranges can fit a vent in one of the triangular panes, others cannot. We will tell you on the quote whether your chosen range allows it.
What is the largest square lantern?
Ranges differ. Many go to around 3 m square, with extra hip bars on larger sizes. Tell us your kerb size and we will confirm which ranges can make it.
How quickly can I get a roof lantern in County Down?
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 County Down.
