Questions from Derry
Can I replace polycarbonate panels with glass?
Usually not in the old frame: glass is much heavier than polycarbonate and the frame was not designed for it. Replacing the whole lantern is the safer route.
My old lantern leaks. Is it the lantern or the roof?
Often the roof or kerb detailing. A survey or close inspection will tell. If the lantern is the problem, replacing it is usually better value than repairing old polycarbonate.
Do I need planning permission for a roof lantern in Derry?
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.
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.
