If you live in cold states then you have to worry about the accumulation of snow on your roof. So, the common misconception is that warm states pose fewer roof related problems.

All of these mean that your roof is under a mold attack and if you don’t want your whole roof to look like that, then you have to act quick.
This article will help you learn more about mold and other such treats and how to remove them.
Roof algae vs. roof mold
A lot of homeowners often use algae and mold interchangeable but in reality, they are different things and require different approach. Let’s start with algae.
Algae is usually black and green, and it is caused by rooftop moisture, which spreads and becomes algae. It can also come from your gutters because that is where the water is. Dampness and humidity trigger it even more. If you let the algae grow then it will eventually rot your roof and the repairs won’t help you anymore, you will have to replace it altogether.
Algae is not always viewed as a bad thing though. In some instances, it gives the roof a nice mysterious look. Algae is natural in its essence, so sometimes if the circumstances allow, property owners let it grow. Of course, in that case, they have to look after it to make sure it doesn’t lead the roof to fall off.
The mold, on the other hand, is not natural and you shouldn’t let it spread. Mold has very dangerous consequences both health wise and for your roof. It has a very bad smell and looks very bad, so you can easily spot it and differentiate from green algae. Mold is also caused by moisture deposits but unlike algae, it tends to grow on wood and other areas that has absorbed water.
