Whether you are planning on hiring a professional or doing the roof pressure wash yourself, there are many things that you should know before starting. Here are some tips that can help you make sure you get a roof that looks brand new and is free of moss and mold.
Cleaning up moss, algae, mold, and mildew
Getting rid of moss, algae, mold, and mildew is not just important to the health of your roof. It can also contribute to the longevity of your roof. It is also a good idea to clean up debris from your roof regularly. This way, you can prevent rot and mold from occurring.
There are several ways to remove moss from your roof. One method involves using a power washer. The problem with this method is that it can damage your shingles. Another method involves applying a chemical solution.
The best solution is a diluted bleach solution. This mixture can be applied to your roof with a sprayer. The bleach will kill any moss, algae, mold, and mildew. You will need to apply the solution to your roof and let it stand for a few minutes. Then you can rinse it off.
Another option is to use a mixture of chlorine bleach and TSP. This mixture is common in outdoor cleaning.
Removing old and loose shingles

You can remove them mechanically by scraping the roof or by applying herbicidal chemicals. It’s also possible to get rid of them chemically by using a special cleaner.
You should use a 35-degree spray wand attached to the pressure-washer hose. This is a more efficient way to clean the shingles and will be easier on them.
Killing mold, mildew, algae, and other roof-degrading bacterial contamination
Several species of fungi and algae are common on roofs. These organisms can cause black streaks and discoloration on concrete and clay tiles. They also cause premature aging and rotting.
The most common types of algae on roofs are yellowish green. These organisms are part of the Chlorophyta division of the plant kingdom. The algae get their color from the chlorophylls forms a and c.
Algae can be a source of roof leaks. It can also damage the structural integrity of your roof.
Fungi and algae on roofs are harder to get rid of. You may need to contact a professional for assistance. Mold remediation is a good solution to your problem. A certified mold expert will use sophisticated equipment to help you clean up the mold and mildew.
To help control the growth of mold, you can use a moisture meter. This inexpensive instrument costs about $10 and can be used to measure the relative humidity of the air.
Preventing damage to shingles and roofing materials
Using a roof pressure wash to clean your roof can be a great way to keep it looking good. However, there are a few things you need to know before you decide to use a pressure washer.
First, be sure to use a power washer only on surfaces that can handle the high pressure. This will protect your roof from shingles lifting and causing damage. It will also protect your roof from leaks.
Second, it is important to keep shingles clean all year. If you let moss and algae grow on your roof, you could end up with a roof that is so bad that you will need to replace it.
Third, you will need to be careful not to damage the shingles with your pressure washer. This is because the high pressure will strip away the protective granules on the shingles. It is also possible to tear the adhesives on the shingles.
Finally, you will need to avoid using harsh chemicals. These can damage your lawn, garden and even your roof.
