How to remove moss from the roof?

If you have ever owned a house with wooden roof shingles, chances are you have seen dirty
patches and stains on your roof. These stains are roof moss and algae. In a way, they can be
viewed as contagious roof diseases, because the wind can carry algae spores from one roof to
another. These spores can start new colonies on other roofs.

This is the main reason why experts suggest owners maintain and clean their roof at regular
intervals. Gloeocapsa magma is one of the most common types of algae that form roof moss.
Having unwanted moss growth in the roof has numerous disadvantages. The drawbacks should
be clear to you if you are searching for ways of roof moss removal. However, they are mentioned below for convenience:

· Devalued aesthetics:

Having roof moss can significantly devalue the aesthetic appeal of your house. The saying looks don’t matter does not apply when you are trying to sell a house. A house with aluminum roof will fetch a lower price on sale when compared to homes with a squeaky clean roof.

· Replacement cost:

If moss growth on the roof is neglected for a long time, it can cause significant damage. The
structural integrity will be lost over time and leakages will become frequent. In situations like
that, replacement is the only choice that remains. All individuals generally agree that moss
removal cost is much lower than replacement

· Health hazard:

Roofs with uncontrolled growth can lead to health hazards among pets and humans as well. If
house pets consume the rainwater runoff from the mossy roof, they can get seriously ill. There
are many scientifically documented cases and reasons to back this fact.
If a person were to figure out the causes of roof moss, he/she would be able to draw the
following conclusions:

· Sunlight and moisture:

These are the main two agents that promote the growth of algae and moss. Places with humid
and tropical climate tend to be a hotspot for unwanted moss. Mosses thrive on indirect sunlight
and humidity like the UK climate.

· Debris:

Fallen leaves and branches on your roof provide roof moss with nutrients to grow. Not cleaning
the roof at regular intervals is, therefore, a grave mistake that leads to the growth of roof moss.

· Other affected houses in the locality:

As mentioned before, roof moss multiplies through spores. These spores are transferred from one roof to another with the help of wind and other animal agents. Roof moss can be thought of as a contagious disease. If one house gets it, the whole neighborhood has a moss removal problem
to worry about.

How does the roof damage occur?

Algae and mosses generally grow in the cracks and gaps between the shingles. As they continue to grow unchecked, they tend to expand the cracks allowing the water to leak in.
Moss is also responsible for trapping water and moisture after rain. This leads to additional
growth of mold and bacteria. If the growth is left unchecked, it can lead to complete decay of
your roof shingles and loss of structural integrity of the whole frame.

Procedure for roof moss removal

To clean moss growth on the roof, one needs to follow caution. Trying to perform the cleaning
task without taking proper safety measures can be hazardous. Numerous individuals have
harmed themselves while doing so. Having a safety harness is imperative when going for DIY
roof moss removal.

Step 1

The first step of the roof cleaning process dictates that you need to clean the roof off the debris.
Tree branches and fallen leaves should be cleaned before beginning with step two.

Step 2

Soak the roof with water. Use your garden hose to spray water all over your roof. You will need
a ladder for this.
The roof cleaner will have to climb the ladder and apply water to weaken the moss growth down. It is best to use a safety rope as a fall back option if the ladder fails you. The soaking will be complete once you notice significant runoff.

Step 3

Scrub the roof with a soft-bristled brush. This will ensure complete roof moss removal.
However, it is not advisable to move the shingles. The cleaner should scrub downwards and
avoid causing any more damage to the roof.

Some individuals recommend using pressure washer instead of scrubbing. It is recommended to
use pressure washers turned to their lowest pressure settings. Using the normal pressure of these
pumps can significantly damage your roof shingles.
