Moss can and does shorten the life span of asphalt as well as other shingles.

I lifted this section about moss and algae growth from somewhere, but I like it alot....


"Significant moss growth was observed on the roof, usually a result of lack of sunlight, high moisture. This natural growth can significantly decrease the life expectancy of this area of roofing and is recommended to be cleaned, and the overhanging branches trimmed back. Some recommendations for cleaning the shingle roofing are included below:

Moss is quite easy to remove. Use a standard bristle scrub brush on a pole and push the brush down the roof to tear the moss's shallow root system from the shingles. Do not brush up the roof as you might break the bond between shingle layers.

Note how the moss typically starts to grow at the top of the vertical slots between shingles. These areas of asphalt shingles are the last place water evaporates from a roof. Once the moss is removed, inspect these slots to ensure the colored ceramic granules are still in place. If the granules are gone and you see just the interior fiberglass mat of the shingle, your roof is well on its way to being replaced.

Green and black algae are not harmful to the actual roofing material because they do not develop roots. They are more of an aesthetic issue since they make the roof look horrible. Both of these algae can be cleaned from the roof, however the green algae is far easier to remove than the black algae.
It is wise to avoid chorine bleach as a roof cleaner. Chlorine bleach can remove the natural color from wood roofing shakes, it can kill vegetation on the ground if it runs onto the ground as it is rinsed from the roof and it can accelerate corrosion of metal gutter and downspout systems.

A better roof cleaner might be non-toxic oxygen bleach <http://www.stainsolver.com>. This widely available powder is mixed with water and applied to a cool roof surface, preferably on an overcast day. If you keep the roof surface wet with the solution for just 20 minutes and then lightly scrub the roof surface, the algae almost always comes off. Severely stained roofs may require multiple applications of the oxygen bleach <http://www.stainsolver.com> solution. The solution also helps to loosen the grip of the shallow moss roots.

Once the roof is clean you can hinder moss and algae growth by introducing copper onto the roof surface. Visit a roofing supply company that sells tin, copper and galvanized metal products to residential roofers. Often these companies sell rolls of copper that can be cut into long strips. I like to cut strips that are 5 or 6 inches wide and are ten feet long. Using a metal brake tool, I put a 20 degree bend one-half inch in from the edge on one of the long sides of the copper strip. This bend eliminates unsightly waviness that often develops as you cut the copper with a tin snips.

Place these strips of copper near the top of the roof. Slide the unbent edge up under a row of shingles so that the bent edge and 4 inches of copper is exposed to the weather. Each time it rains some copper molecules wash down onto the roof and create a poisoned environment that both the moss and algae dislike. Be patient as the copper eventually will turn a distinctive dark brown and then the classic green color. If you getting ready to install a new asphalt shingle roof, be sure to buy shingles that have copper hidden in the colored ceramic granules."

No one knows what they do, though. They skulk around in
