we have a keystone residence. i noticed a couple small spots on the roof that looklike mold. is it possible for mold to grow from the underside of the rubber roof?
i tried soma bleach a couple weeks ago but i wll try again next weekend. this spring i recaulked all roof openings and side and end edges as regular maint. the roof was really dirty with all the storms we had and i hadnt cleaned since the spring so when i cleaned it thats when i saw the mold. there were also some small lighter spots in other places.
