Clear Shed Roofs Can I Use Benzene To Help Clear Out Dried Leaves On My Roof?

Can I use benzene to help clear out dried leaves on my roof? - clear shed roofs

It is a tree beside the house, the tree is its leaves, throw on my roof and blocking the escape, which allegedly represented the rain. It is too dangerous for me to go on the roof, I thought if I gasoline on dry leaves, set on fire and scattered the fire was "clean", I could save the trouble and the dangers of walking on the ceiling and the wind carry the ashes. Has anyone a better idea?
