I would be very cautious about using LA's Totally Awesome on your roof, and would contact the roof material manufacturer first. It may or may not have petroleum products, but that is not the only type of chemical that could degrade the material on your roof.
From what I have read -- and I also have a bottle of the stuff -- it can cause irritation to the lining of the nose and throat suggesting that it is very caustic. How that impacts on the roof membrane is unknown. It is very effective as a degreaser and the stain That you have is not a grease-based one but probably tree sap or something similar, so a different cleaner might be more effective. A common removal agent is rubbing alcohol but again, consult with the manufacturer of the membrane.
This is what
