Can a flat rooflight open?
Some ranges offer electric opening versions. Ask for availability for your size.
Do flat rooflights leak?
They should not, provided they are installed on a properly flashed upstand with the right fall and the seals are maintained.

Usually, size for size. They use one glass unit and a simple frame.
