Roof Cleaning | Safe Moss Removal


Many roofs have moss growing on the shingles.  This infestation is not something you should ignore.  If left unchecked, the damage can be pretty severe. The following is taken the Asphalt Roofing Manufacturing Association:

Moss is a non-vascular plant that obtains water through its leaves, unlike most plants that gather water through its root system. Moss must therefore have a moist environment to survive. In North America, moss tends to grow on north facing roof planes that receive less direct sunlight and stay damp longer than south facing planes. Overhanging tree branches provide additional shade and drop debris on the roof that further holds in moisture and acts as a food source for moss.

Moss spores may also be carried by wind or animals and can easily spread throughout neighborhoods. Unlike algae, moss can be detrimental to asphalt shingle performance. Moss can cause the leading edges of the shingles to lift or curl, which increases the risk of shingle blow-off during wind events. In severe cases, moss build-up can cause lateral water movement resulting in moisture damage to the roof deck or may even cause leaks.

So left untreated, moss can drastically shorten the lifespan of your roof, or even cause leaks in your house.
