Spots on roof
I would guess those are more likely to be a stain - not a sign of deterioration...but that is only a guess. I would be tempted to put my thumb on the dark spot and wiggle it back and forth just to see how it reacts - then do the same with a non-spot section. If the reaction is the same then I would think the membrane material is not affected or deteriorated. Just a thought...I am not a roofer!
