Roof Moss Removal


Ever wonder what those dark stains are on your roof? Those dark stains are algae, actually a particular strain of algae that only grows on roofs. Algae isn’t the only problem your roof can encounter. Fungus, moss and lichen can also destroy your roof. However, all of these plants have several things in common. They all love a wet environment especially standing water on your roof, they all love a humid environment, and thrive wherever there are overhanging trees that create shade on your roof.

The first thing you should do is learn how to recognize algae, fungus, moss, and lichen. Once you know what to look for you will know how to prevent algae, fungus, moss, and lichen from growing back on your roof.

Black roof algae creates black stains and loves to eat away at asphalt shingles. Black roof algae also known as Gloeocapsa magma quickly spreads over your roof creating a very thick root system. Black algae is naturally black in appearance and is found wherever there is standing water in a shaded area on your roof. Overhanging trees create the shaded environment blocking sunlight which keeps a roof dry and warm.

Another form of algae is green roof algae. This is more common than black roof algae. Green roof algae is obviously green in appearance and spreads and feeds the same way as black roof algae. Most often when green roof algae is in its beginning stages it looks similar to black roof algae.

Another problem is roof moss. Moss is usually green in appearance and is thick and spongy. Moss loves water and retains all that is takes in which creates its spongy consistency. The root system of moss is much smaller than that of algae, however, it is much stronger. Moss is a slow grower sucking up moisture wherever it can find it and loves to feed on asphalt shingles.

Lichen is moss in its beginning stages. Lichen can appear as tiny strands that can either be black or green. As the lichen grows and gathers water it turns green and becomes thicker. Once the lichen has matured it becomes moss.

Fungus is an airborne spore that lands on your roof and immediately begins feeding on the roofing materials. As with algae, moss, and lichen, fungus loves standing water in a shaded and humid environment. Fungus is similar to mold in appearance except thicker.

The only way to avoid any of these plants from taking over your roof is to trim the branches of overhanging trees allowing sunlight to keep your roof warm and dry. If you are unable to trim your trees be sure to have your roof inspected at least twice a year to check for growth of any of these plants.
