How do i get rid of mold on roof shingles.

Make sure there is someone on the ground in the case of an emergency. No pressure washers please. Black stains on your shingles could be mildew or just dirt. Never go up on a roof alone.

Next rinse the shingles thoroughly with a garden hose at low pressure. Hose and fresh water. Mix a solution of chlorine bleach and water at a mixing rate of 7 parts water to 1 part chlorine bleach. Mold stains can form on roof shingles that are in permanent shade.

These stains will discolor your roof and damage the shingles over a period of time if left alone. One way to determine if it s mildew is to put a few drops of chlorine bleach on to the black mark. The roofing contractors mix this bleaching agent with water and spray the roof down paying close attention to areas that are stained. They will let the mixture stay on the roof for a bit to ensure it penetrates the stain.

Start from the top shingle and rinse downward to prevent water seepage. The less expensive solution is to spray wash the roof with a 50 percent mix of water and bleach to get rid of the algae. Remove large pieces of mold or moss by hand. Ladders or portable scaffolding.

If they are severely molded you may want to give it a little longer. Allow the solution to soak into the shingles for at least 15 minutes.
