Questions from Derry
Can the coating be damaged?
Yes, by abrasive cleaning, some chemicals and silicone. Follow the care instructions supplied with your lantern.
Does it work under trees?
Less well. Sap and leaf debris build up faster than daylight and rain can deal with them, so lanterns under trees need more regular rinsing.
How quickly can I get a roof lantern in Derry?
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 BT47.
Who checks building regulations for a lantern in Derry?
Your district council's building control service. For a lantern in a new extension it forms part of the extension's approval; replacements in existing homes have their own rules.
