Moss and algae can be very damaging to your roof. When there is moss and/or algae growing on the roof, they will hold moisture on the roof and this can cause problems with the roofing materials. For example, if you have a shingle roof, then the shingles can end up getting soft and weak. They will be prone to tearing and this can cause there to be leaks in the roof. If you have large areas of moss and algae, then this means there can be a large section of your roof that's vulnerable. Something you can do to protect your roof from these types of damages is to have it soft washed. You can learn more about moss and algae damage and how professional soft washing can help.
What soft washing is
Soft washing uses water at a low pressure to remove dirt and debris. However, it will also remove moss and algae, which is important for the integrity of your roof. The pressure of the water will clean the roof without being strong enough to cause damage to the shingles, tiles, or other roofing materials.
How moss and algae grow
While the dirt and other debris of your roof will be loose on the surface, moss and algae will be attached to it. The moss and algae will continue to grow over time. As it grows, it will spread and cover more surface space. The sooner you are able to spot the start of moss or algae appearing on the roof, the better off you will be, as long as you act accordingly. You should call to have someone come soft wash the roof as soon as possible to keep the roof in the best shape.
How to spot moss and algae
You should know what the beginning signs are, so you catch things as early on as you can. Watch the darker spaces of the roof, because this is often where moss and algae will start. Also, it tends to grow in areas where there is less airflow, such as in areas where a tree branch hovers over the roof, along the shaded side of the roof, or in the valleys. You'll see a darker area at first, then there will be color changes. The colors won't always be green, as moss can come in a variety of colors. As soon as you see any changes, you should call for a soft wash.
Why professional soft washing is important
When you see you should have the roof soft washed, you want to call the professionals to tend to this job. Balancing on the roof while working with a soft washer can create a very dangerous situation. Plus, the professionals will ensure the job is done completely, and that steps have been taken to help prevent the return of the moss and algae for as long as possible.
