Roof algae look like black mold stains that are more apparent on light-colored asphalt shingles. It is more likely for algae to build upon your roof if you live in warm areas with humid summers. While it is not damaging to your roof, it is not very pleasing to look at. This article lists down some of the safe methods to remove algae build-up on your roof.

4 Safe Methods To Remove Algae Build-Up On Your Roof

Low-Pressure Cleaning

One of the primary ways to remove algae build-up on your roof is to perform low-pressure cleaning or roof soft washing. Most reliable roof experts recommend this roof cleaning process because not only is this safe for your roof, but it is effective too. Soft washing is a gentle process that penetrates more in-depth, thereby not only cleaning the exterior of your roof but getting rid of bacteria and grime as well. It can even eliminate the deeper contaminants that are not seen with the naked eye.

Power Washing

Another method to remove algae build-up on your roof is to use a pressure washer. In this way, you will be able to clean away the moss, but you need to ensure that your roof shingles are not broken, chipped, or damaged in any way beforehand. Otherwise, the high pressure is most likely going to worsen the damage to your roof and the water may even seep into the tiny cracks present. Another factor that you need to consider is that when you go for this method, you need to stand on the roof above the mold for you to be able to target the power washer in a downward direction, using the lowest setting possible.

Scrubbing

There is also the option for you to scrub the shingles of your roof to remove algae build-up on it. In this case, you need to use a scrub brush or a long-handled soft bristle brush that will allow you to gently scrape the moss from your roof shingles. You can work on the small sections first, moving the brush downward to protect your shingles from damage. After this, you can already apply a moss-remover cleaner.

Replacement

Finally, when your roof shingles are already worn out, then it makes sense to replace them with new ones instead of attempting to clean them. In this case, you can go for new shingles that are dark enough to disguise the staining, or you can even acquire shingles that are laced with copper granules because the latter is lethal to algae. Just keep in mind that as soon as you have replaced your shingles, you still need to maintain your roof.

4 Safe Methods To Remove Algae Build-Up On Your Roof

If you notice black mold stains on your roof, which are most likely algae, you can go for low-pressure cleaning or use a power washer to remove them. There is also the option for you to scrub the stains until they are removed or replace your shingles, particularly if they are already worn out anyway. Otherwise, you can leave your roof cleaning needs to the expert who will be able to remove the algae build-up on your roof effectively because they have the knowledge, skill, and tools to do so.
