Killing Moss on Roofs Naturally: Baking Soda Spray and Sun Exposure

Baking Soda Fungicide

Dissolve 4 teaspoons of baking soda per gallon of water. Put in a garden sprayer and saturate the moss. Repeat after a week if needed.

Address the Cause: Shade & Moisture

Trim overhanging branches to increase sun exposure.
Sunlight naturally inhibits moss and algae.
Ensure gutters drain properly to reduce constant dampness.

Why Not Chemicals?

Chemical moss killers (zinc, copper sulfates) leach into soil and waterways, harming plants and aquatic life. Baking soda is non-toxic, cheap, and effective.
