I have a concrete sectional garage with asbestos roof, Last few days it has a lot of consensation on the roof which is not good, how or whats the best method to combat this,

I've currently got a dehumidifier running in there, the garage is well ventilated, I've read some where about leaving a fan running to keep the air constantly circulating so it doesn't get to settle and cause the condensation

Any advice or opinions please?

condensation forms on the barrier between hot and cold, always on the hot side, thus you are getting it on the underside of the roof sheeting I presume. This would indicate, that thankfully it is warmer inside the garage than outside.
To address this a layer of insulation is required to separate the hot and cold. A good one to use would have a vapour barrier, a sarking and hydroscopic materials.
A good product that is designed for retrofitting would be something like:

would be better and more cost effective in the long run to insulate than running a fan all day etc

I have the same problem with the tin roof in my garage, when the summer comes around I`ll strip it and put marine ply on the roof with felt over that then put the tin back on, that`ll stop it. Asbestos though, not nice.
