Questions from Formby
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.
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.
