Roof Washing 201
Did you know that more than 50% of asphalt shingle roofs have algae, moss or lichen growing on them? Did you know that 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 and allow water to get to the underlying roof deck. Moss and lichen, through their root system, can raise shingles allowing the wind to tear them off.
