What Are The Important Reasons Considered For Roof Cleaning?

Every part of a house is important and it adds to the beauty of the total house in its own way. If any part is left dirty then it makes the entire house look out of order. All the homeowners put a lot of emphasis on cleaning the interior of the house. They also consider cleaning the lawn and the pathway but the roof is often overlooked.

Roof cleaning is as important as cleaning any other part of the house because it too adds to the beauty of the house. If the roof is left dirty then it will reduce the curb appeal of the house which is surely not desirable. There are some more important reasons that make it very crucial to clean the roof at regular intervals.

Accumulation of debris

It is a known fact that roofs are uncovered and they are exposed to the dirt and dust of the whole atmosphere. Debris gets accumulated on it in the form of leaves, branches from trees, and many others. Rain washes away some dirt and dust for sure but it is not enough. There are layers of algae, fungi, and mosses that cannot be washed away by rain and this surely calls for a roof cleaning.

Algae tend to form a black layer on the roof. It is more evident in the shaded parts of the roof as these microorganisms grow in places that are moist and free from direct sunlight. Fungi also develop similarly and grow when it gets a good amount of rainwater.

Mosses are plants with fine roots and grow on those portions that are damp and receive faint sunlight. Therefore the roof gets covered with all the microorganisms that breed on it freely if it is not cleaned regularly. Not only they restrict their growth to the roof, but they also expand to the walls of the house slowly.

Damage of the roof

All the microorganisms that accumulate on the roof can damage the roof slowly without even coming to the notice of the house owner. Their fine roots start penetrating through the upper layer of the roof and thus the damage starts very fast. Once the top layer starts getting damaged, it will soon penetrate through the walls and in no time the house will turn old and shabby.

Therefore roof cleaning is very essential as it will not only add beauty to the house but also protect it from any sort of untimely damage.

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:

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.

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.
