Frequently Asked Questions
Do roof lanterns need planning permission?
Most cases don't require it if they don't extend more than 150mm above the existing roof slope. Listed buildings and conservation areas may need approval.
How much do Korniche roof lanterns cost?
Typically between £2,500 and £6,000 installed, depending on size and specification.
Are roof lanterns better than skylights?
Roof lanterns sit above the roofline on a raised frame for greater architectural impact and light capture. Skylights sit flush — better for pitched roofs.
Do they make a room too hot?
No — Korniche offers solar control glass options (blue or neutral) to regulate heat and glare.
What size do I need?
Depends on your flat roof area and desired light levels. Our free survey will help determine optimal sizing.
