Find out what causes those ugly black spots that appear on roofs 👷

We always wonder what causes roof stains in Marietta. These usually appear on the surface of the shingles and are an aesthetic problem that can develop into something worse. For many people, however, the most important thing is the deterioration of the roof’s appearance.

It is not for less, the appearance of a property has a lot of weight in the future decisions that you can have with this. That is to say, those moments when you need money or you are simply going to move to a new place. Finally it is time to make one of the following decisions:

  • Rent the house and receive a monthly income based on the conditions of the house.
  • Sell the property and get the full assessed value.

In both options it is important to talk about the value of the property. That money that you can obtain for the profitability of your property depends a lot on the conditions in which it is. Repairs made, improvements, deteriorated arts. Everything adds and subtracts until finally we find an established price.

However, there are many occasions in which this price does not correspond with our pretensions. The reasons are varied but one of them is the stains on the roof. This notably discounts the value of our property and therefore we will not be able to meet our economic objectives. The best way to avoid this is for you to look at how to prevent stains.

Preventing roof stains in Marietta is important

When we think of stains on our roof,we can imagine all sorts of causes. Fungus, bacteria, dirt, many of these options really don’t come close to the real reason. It is important to identify the culprit of this problem in order to know how we should act.

In most cases we find that what causes roof stains in Marietta is algae. Hard to believe? Specifically we are referring to Gloeocaspa Magma, a specimen characterized by being continually blown by the winds. This is how they invade roofs and houses in the same neighborhood.

  • The presence of this problem with algae in neighborhoods with many trees stands out. In fact, these are environments where the same algae can develop easily.
  • Algae are not only an aesthetic problem, but also deteriorate the functions of the roof tiles. Breakage is the main consequence and can lead to the total loss of the shingles.
  • Beyond the fact of seeing the value of your property reduced, you may have serious problems to replace the roof. That is to say, this type of problem leads to a total replacement or at least a large number of shingles. This is a major expense to protect the rest of the house.

There is no doubt that algae contamination of the roof is a very important problem to avoid. This is why it is important to know how we can remove these stains from our roof.

Roof stains in Marietta have a solution


By knowing what causes roof stains in Marietta we can determine exactly how to remove them. After all, experts have let us know what formulas are used for this task.

Eliminate excess branches

One way to prevent this problem from being able to occur on your roof is to prune nearby trees. This will reduce the places where this type of algae can develop and then fall on your roof. In addition, it also helps prevent organic waste from trees on your roof.

Sodium hydroxide

Bleach is one of the most important products in cleaning surfaces infected with bacteria. However, it is a product that must be handled with care. Especially because it is a product that can deteriorate tiles and nails, so it is used dissolved in water.

Copper and zinc strips

There are many experts who claim that algae detest galvanized steel products such as zinc and copper. That is why a good option is to install copper and zinc strips on the roof ridge. This way, algae will not be able to settle comfortably and it will be difficult for them to develop.

Avoid pressure washing

Anyone would think that a powerful high-pressure water jet would be enough to remove algae. However, this is a mistake you can’t make. You will only end up deteriorating the protective functions of the tiles by removing the granules. That’s why you should always consult a professional before acting against roof stains.
