Hello,
I'm in the process of installing a rain water tank on my flat roof to store water to water the garden with during the summer. I've bought a
200 litre plastic tank (weighing 200 kilogram when full), and was wondering if flat roofs in general can take this weight. I was thinking of setting the tank on two 1 metre concrete beams, side by side, to spread out the weight, but these together with a concrete block I was also thinking of putting in the tank to stop it blowing away when empty, is also extra weight.Can anyone advise?
Many thanks, Paul
