Why The Siding Is Turning Green

Posted on

When you had the siding installed on your home, you didn't choose green as the color. So, if your siding has turned green, you're probably trying to figure out what the problem is, and most important, what you can do about it. Here is some information that can give you answers to your questions.


More than likely, the discoloration on your home is the result of the growth of some type of organism. Learn about the two most common culprits.


If your home is located in a very humid climate, you have probably seen algae growing on other buildings, but now you might be dealing with the problem yourself. Algae is the result of accumulated dust and dirt on your siding that traps moisture. The dirty and moist environment is perfect for algae development, hence the reason why you're dealing with the problem now. Algae is not damaging to your siding, but it is more of an eyesore. Additionally, once you have a small area of algae, it's only a matter of time before the area expands.


No matter where you live, some level of moisture will accumulate around the exterior of a home. In most cases, this moisture is not a problem. However, if you have a leaky gutter and the moisture is almost constantly dripping on to your siding, mold is bound to form at some point. Unlike the toxic mold found in other spaces, the mold that forms on the outside of a structure often takes on a green-like appearance. 


When it comes to what you should do about the discolored siding on your home, the reason for the discoloration will help point you in the direction of the right solution. For example, if you just have algae, a professional cleaning will likely be enough to eliminate the problem. On the other hand, if mold is to blame, you want to have a siding professional look at the area. 

While mold can occur from moisture on the surface of the siding, mold can also form due to a moisture problem underneath the siding. Moisture issues on the siding's underside are often more severe and may even require that the siding is replaced. 

If your siding is turning green, make sure you recognize that this sign also means that's it's time to enlist help. Contact a company like Weather-Tek Home Remodeling Center to determine what you need to do for your home.
