Why do I need to remove the algae from my house?

Alage Mold On A House With Vinyl Siding

First, let’s answer the question with another question.

What are algae and where does it grow?

There are many species of algae, as algae are a diverse group of simple organisms. Just like plants, these organisms all go through the process of photosynthesis, using sunlight to make food from carbon dioxide and water.

Many species of algae, like the green varieties, are related to plants. Like plants, algae also need access to lots of water to grow. However, green algae don’t have stems, leaves, or true roots.

Algae is present in the soil, and it sends its spores through the air which the wind is notorious for picking up and depositing onto your roof, deck, driveway, and other places around your home. Algae can grow on multiple surfaces, including your porch, patio, awning, siding, fence, sidewalk, and even on your outdoor furniture.

That leads us to the main question. Why do I need to remove the Algae?

Algae damages surfaces

Algae growth on decks and other walkways will make the surface very slippery. This can cause a hazard for you, your family, and your guests. Not to mention the risk of hurting how well you and your family can breathe.

Algae growth on your roof can not only ruin the appearance of your home, but it can also wear on your shingles over time. As the algae build-up, your roof becomes less reflective and will absorb more sunlight.

The excess of sunlight can increase the amount of heat your roof absorbs. Unfortunately, this means you can expect an increase in cooling costs.

If the algae form a partnership with fungus, it will develop into lichen, an invasive growth that could cause serious damage to outdoor surfaces.

How do I get rid of algae?

You might think that pressure washing is the best way to remove algae. However, the force of the water can cause your shingles to lose their protective granules.

Pressure washing can even tear shingles off your roof! Some homeowners also try to get rid of algae by using bleach. Bleach is a caustic chemical that can kill your lawn and plants.

It can also rust your downspouts and cause your shingles to shed their protective granules prematurely.

Here at The Washing Guy, we use a technique that is known as Soft Washing it utilizes a very mild pressure with non-harmful chemicals to not just knock away the Algae but to permanently kill the existing algae. Protecting your home.
