How to remove mould from your roof
You don’t need to be a professional to remove mould from your roof. This is one of those jobs you can do on weekends, and you may find it to be quite enjoyable. It is a great activity to do for your body.
Over time, mould forms on the roof. Mould growth is especially encouraged by the hot, humid Australian climate. Different people have different opinions about mould. Some people love it, while others find it annoying and need to be eradicated. South Australia is an example of a state where mould growth can be encouraged. This helps to give homes character and makes them look older. They absorb moisture from the tiles.
Mould growth on your roof is not a good idea. Although it does not affect the quality of tiling, some mould can seep into core structures and weaken them over time. Even if you love to see mould gowth on your roofing, it is important to keep them under control.
How to Get Rid Of Mould From Your Roof
You have two options when it comes to mould removal: you can either hire a professional roofing service that has the necessary skills and materials or go DIY. Certain techniques and chemicals are required to remove mould. The following are some of these processes:
Use Chlorine Bleach to Remove
The most common and effective way to remove mildew and mould indoors is with chlorine bleach. The mould growth outdoors, such as on roof shingles, is more resistant than normal bleaching agents. This is where stronger solutions are needed to remove the mold, such as a combination of TSP and chlorine bleach. This is how you can remove mould using chlorine bleach that is more powerful.
The strong bleach mixtures can cause injury to sensitive areas of the body, such as the eyes. Wear protective clothing and a mask when applying bleach. When preparing the bleach mixture for roofing cleaning, you should wear a mask and gloves.
Protect your plants and gardens from strong bleach solutions by covering them with plastic sheets or a tarp. This will protect the soils surrounding the roofing.
Mixing ordinary household bleach with trisodiumphosphate or TSP and water will create a heavy-duty bleach mixture. Mix 1 part chlorine bleach with 3 parts water. Mix the mixture with a tablespoon of trisodiumphosphate.
You can use a garden sprayer or a pump to soak the affected area of your roof.
It should be left for approximately 10 to 15 minutes.
Use clean water to remove any mould from the roof. It is best to wash the roof with low pressure water as power washing can cause asphalt shingle damage.
Allow the roof to dry before inspecting it for mould growth.
To check for mould, run your fingers across the roof surface. Repeat the process if the roof surface remains slimy or if you feel that mould residues are coming off your hands when you touch it.
Apply the bleach mixture after the roof surface has dried. A wet roof surface can dampen its effects.
Make sure you are buying a mould-removal cleaning agent that is not sodium-based. The sodium component of the bleach can cause damage to roof tiles through electrochemical reactions. Be careful with bleaching agents that contain sodium hydroxide, as this can have a very corrosive impact on your roof.
However, the industry is moving away from using household bleach as it can damage asphalt roofing. This is especially true if the bleach is left on the surface for too long. This can be avoided by applying the bleach in small pieces and leaving it on the roof for a few minutes. This will greatly reduce the potential damage to the roof. Bleach has no long-term effect on mould, and they will likely return even after thorough cleaning.
Other Mould Cleaning Methods
You have many other options to kill mould from the roof. Some even have an anti-mould permanent effect. They include:
Bluestone or copper sulphate can be used to remove the mold from the roof. It is possible that it will cause a corrosive reaction on the roof, just like stronger household bleach. Therefore, you should use water while cleaning. For every 2kg bluestone, you should add 45kg water to the cleaning mix.
Zinc strips can be applied to the roof surface to prevent moss growth. They have a long-lasting effect and can prevent the reoccurrence of mould. Zinc strips are attached to the roof’s peak or tip. This allows rainwater to dissolve in the zinc strip and flow over the roof, coating it. This protects the roof for many years and prevents mould growth.
You can either apply a pre-paint or a fungicide to the roofing after washing it. This will prevent growth due to their antifungal action. Fungicide paints contain ingredients that have a high level of antimicrobic activity. They are non-corrosive, and they do not contain dangerous chemicals that could have a negative impact on the ecosystem and surrounding vegetation.
Professional Roof Rejuvenation
You can save money by spending it on a professional roof restoration service. Roof rejuvenation involves cleaning the roof, painting the roof and re-tiling the roof. Roof cleaners are usually experts in choosing the correct cleaning agent to clean your roof. Because of their industry experience, professional roof cleaners are likely to know the best cleaning products to use to protect your roofing and prolong its life.
