Moss

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 branches provide additional shade and drop debris on the roof, that further holds in moisture and acts as a food source for moss. Additionally, moss spores may also be carried by animals or wind and can through these sources, quickly and easily spread through neighborhoods. Moss can be a burden on your asphalt shingle performance. It can cause the leading edges of the singles to lift or curl, which increases the risk of shingle blow off during high winds. In extreme cases, moss build up can even cause lateral water movement resulting in moisture damage to the roof deck and may even cause leaks.

Algae

Another environmental factor affecting your roof in a problematic way is algae. The black discoloration and streaks visible across many roofs across the United States and Canada Algae Chase Construction North West Inc.are actually algae. The algae forms where moisture tends to reside on roof surfaces. The most common type, blue green algae, protects itself from damaging ultraviolet rays by producing a dark, pigmented sheath.  By the time algae has been discovered, it has likely been present for several months or longer. The algae discoloration typically begins as small spots that quickly transform into streaks on the roof plane. Though there is no scientific evidence suggesting that algae is damaging to roof shingles, it certainly affects the aesthetics of a roof.

How to Protect your Roof

There are some steps that can be taken to discourage moss and algae growth:

Chase Construction North West Inc.Trimming tree branches back to allow more sunlight to reach the roof and minimize debris accumulation will provide an environment less inviting for such growth.

Chase Construction North West Inc. Debris that does begin to accumulate on the roof should be cleared regularly with a leaf blower or similar, non-abrasive method as part of a regular maintenance program.

Chase Construction North West Inc.Air flow should be directed down the slope to avoid driving debris under the edges of the shingles.

Chase Construction North West Inc.Keep gutters clean to promote proper water drainage. Do not allow gutters from an upper roof to drain directly on a lower roof; extend the downspout from the upper roof into the lower gutter.

Other preventative measures —such as adding zinc or copper strips to prevent both algae and moss, or applying asphalt shingles that incorporate algae resistant copper granules —may be employed when it is time to replace a roof. Currently, there are asphalt shingles available that use algae resistance technology.
