Questions from Altrincham
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.
Can you fit a roof lantern in Altrincham?
We can quote for fitting where we have cover. Send your postcode and photos of the roof and kerb, and we will confirm before quoting.
Is it worth having solar-control glass in Altrincham?
With the midsummer sun about 60.1° high at noon, roof glass in Altrincham gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
