How to Remove Algae From Your Roof

The existence of algae on your roofing is not only unsightly however can end up being a pricey headache. Doing something about it to remove it is important to reduce its impact and prevent damage to your home. If you have discovered algae on your roofing system, what should you do now?

The best method to securely and successfully remove algae from your roof is to hire a professional to perform a roofing treatment. While it may be appealing to do yourself, roof treatments require unique soft cleaning equipment and cleansers. Plus, who wants to climb up a second-story ladder? In the end, calling an expert is a more sensible and cost-effective choice. More on that later on in the post.

This post will cover everything you require to understand about algae on your roofing system. We will discuss what it is, where it comes from, and the safety measures you must take prior to removing it. We will then get to all the advantages of hiring a professional to get rid of the algae.

WHAT IS THE ALGAE (OR GREEN STUFF) ON MY ROOF?
Gloeocapsa lava is the clinical term for the algae on your roofing system. While it is technically cyanobacteria and not algae, we refer to it as algae in this post since that is what many people know it as due to its green colour.

As the algae feeds upon the limestone in your shingles, it leaves behind a black residue that spots down the roofing. If left neglected for sufficient time, the algae can separate the granules in the shingles and require them to be replaced.

WHERE DOES THE ALGAE ON MY ROOF COME FROM?
Gloeocapsa lava spiked in the southeastern United States in the 1990s. It is thought that this is a result of rising humidity. Around the same time, roofing makers were changing shingle filler from paper and ceramic to a more affordable, but algae-attracting, limestone filler.

Algae is most typical in locations that have a cool and damp climate. Because of the environment in the Midwest, these roofs hold moisture longer and produce a breeding ground for algae. Algae colonise where there is an absence of direct sunlight, which is normally the north side of the roof. While it is most typically found on shingles, algae can also be seen on siding and other areas of a house’s outside.

Algae spores blow from roofing to roofing, through the air, and land on your roof. As more algae arrive on the roofing, the dark areas avoid the roof from reflecting sunshine. This can result in excess heat on the surface, reducing the roofing system’s life time. Eventually, your roofing system can become so unclean that you might think the shingles need to be replaced. Gloeocapsa lava can be neutralised with the right treatment.

HOW TO REMOVE ALGAE FROM THE ROOF?

Bleach will reduce the effects of and eliminate algae off your roofing system and eliminate the black streaking. This comes with risks. Bleach is destructive and hazardous to plants and family pets. It should be diluted before used and plants need to be rinsed down. Also, your home needs an appropriate place to drain pipes chemicals. Not to mention, dealing with a roofing system requires using a ladder.

Due to the variety of risks at play, we do not suggest attempting to treat a roofing system yourself.

HIRE A PROFESSIONAL TO TREAT THE ALGAE ON YOUR ROOF
There are lots of essential advantages to hiring an expert to treat your roofing. Working with an insured professional will protect you against any harm caused to your roofing or the worker.

Second, it is likely there are more living organisms on your roofing system than just algae. Gloeocapsa magma has a cooperative relationship with particular fungus that causes the development of lichens. A specialist will examine and treat the roofing system for mould, lichens, and the starting stages of moss.
