I have a garage flat roof, which no longer appears to be tight. Half of the underside is thereby covered with mold! I saw myself already forced to put an pent roof top, for some 1,000 euros, as was my neighbor who owns the adjacent garage with the same problem the tip, Mellerud mold remover to use. I filled 2 bottles of MS in a large garden sprayer, spraying a ceiling. The next day I washed the ceiling with a high pressure cleaner (rotating brush). The result was amazing!
