Frequently Asked Questions
How much do roof lanterns cost?
Final price depends on lantern size and glass specification (double-glazed standard, solar-control or self-cleaning options). Every installation is FENSA registered with a 10-year CPA insurance-backed guarantee. Request a free no-obligation quote.
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 may need approval — our team can advise during the free survey.
Do they make a room too hot?
Modern systems use solar control glass and thermally broken frames to regulate temperature. We can specify blue or neutral solar control glass.
What guarantees do you offer on roof lanterns?
Our slimline aluminium roof lantern carries a 10-year manufacturer warranty on the powder-coated frame and a 5-year warranty on the sealed glass units against seal failure or misting. The structural opening and weatherproofing are FENSA registered, and Vitrum Solutions adds a 10-year CPA insurance-backed guarantee on the installation workmanship.
