Gray fungus on roof.

If you wish to prevent reoccurrence of fungus think zinc. Fungus which also travels through the air can combine with algae already present on your roof and form into lichen. When it rains a slight amount of zinc dissolves from the strips and coats the roof inhibiting algae and fungus growth. If the roof fungi haven t damaged the structural integrity of the roof you should be able to clean it yourself.

This lichen feeds off both the algae and the shingle filler. This occurs when the temperature of the sheathing drops below the dew point creating a thin layer of moisture on the substrate. Start on lowest row of shingles and work your way backwards to the upper part of the roof. It s a combination of algae and fungus and usually has a light mint green color.

What is gray mold. Spray the entire roof thoroughly. Unlike algae lichen can develop roots which makes it harder to remove than algae alone. Bleach kills fungus on contact.

In the vast majority of cases the mold growth is caused by condensation. It doesn t trap as much water against the surface of the roof as moss but it can be acidic and has strands that can penetrate into the shingles. It then spreads quickly and can cause extensive damage to healthy parts of plants. Zinc strips left have been used for many years as an algae preventative.
