Most people don’t know that more than 50% of asphalt shingle roofs have algae, moss, or lichen growing on them. These organics can reduce the life of a roof by 20%. Algae alone can cause considerable loss to the granules that make up the shingles, causing the shingles to curl and crack, allowing water to get to the underlying roof deck. Moss and lichen, through their root systems, can raise shingles, allowing the wind to tear them off.
