Run your gloved hand over the shingles to check for any slimy mold remaining after you re finished rinsing.
A pressure washer can eradicate the moss from the deep crevices and prevent it from returning next season.
The areas directly below the flashing will be free of any algae stains.
After 15 to 20 minutes rinse the solution off with a sprayer that has enough force to dislodge algae and moss without damaging the shingles.
That ll prevent the cleaner from drying out too quickly.
Wait about 20 minutes then rinse.
