Weight of a Nova roof skin?

Don't suppose anyone knows the weight of a Nova roof skin (steel) please?

Or has a cut-off roof that could be weighed?

Thanks,

I know i saw people remove their roof skins in the past but they don’t come up in goggle..

however i did find a full carbon roof (with reinforcement sections) weighing 3.3kg
and a full bare shell door (exactly like original inner and outer skins) weighing 4.5kg

If you know the weight of a steel door you could do the math for some sort of reference

or if you have a section of the same thickness sheet, weigh and calculate to the square meter of the roof.

If you're looking for exact figure, apologise i can't be of much help.
