Is Roof Cleaning Important?

20th October 2020

Dirt accumulation and growth of algae and moss naturally happen on every rooftop. Yearly maintenance is important to avoid affecting the lifespan of your roof. These particles tend to trap moisture and prevents sunlight from reaching your shingles. So, if you want your roof to possess a better lifespan, then a proper St Helens roof cleaning is crucial here. Leaving these ugly streaks on your roof is going to eat up all of your shingles. You don’t want to replace your entire roof, do you? So, spring cleaning your rooftop once a year is an absolute must.

What Is Causing the Stains on Your Roof?

The stains present on your roof are known as “Gloeocapsa Magma.” It is a blue-green alga, which is a strong breed. This algae multiplies and spreads fast if you don’t thoroughly remove it. Your shingles will lose years from its actual life span. The Gloeocapsa Magma is not visible at all during its early phase.

Once it is advanced, it will turn black and will be visible to our eyes. So, seasonal cleaning is always required. One part of your roof may have stains, and the other part might not. However, that doesn’t mean it won’t spread. So, you always have to be cautious and take extra measures.

Why It Needs Cleaning at the Earliest?

Yes, roof cleaning isn’t a part of the daily chores. However, you should clean it at least twice a year at the max. The roof is your shade at all times, and so algae and moss growth are no stranger here. They prefer climates that are a little damp and dark to grow. If you don’t treat it, it is likely to spread at a rapid pace. The moisture and rainwater tend to be trapped below the moss, which eventually causes it to feast on the roof.

Your shingles will start decaying and possess a shorter lifespan. There are times when mildew fungus and dirt start collecting on the roof too. They are not as harmful as algae and moss. But dirt still tends to trap moisture on the roof, which will lead to decaying. All these factors will hinder the curb appeal of your home. So, if you plan to sell your home in the future, then cleaning them should be prioritised more.

How Much Is It Going to Cost?

There are two ways to finish the job here. You could either do it by yourself or hire a roof cleaning professional. If you are planning to do it by yourself, then you need to get the right equipment. A garden sprayer will do the work, especially for getting rid of mildew fungus and dirt. However, to get rid of algae and moss, you need professional help. If the shingles are getting softer or damp below the growth, you need to start calling the professionals at Just Clean Property Care.
