Dealing With Roof Stains: What You Need to Know

Aside from being unsightly, roof discoloration could lead to further damage if not addressed properly. One way to solve this problem is by being aware of what causes roof stains, how to identify and clean them and how to stop them from coming back. 

As one of the most reliable flat roof contractors in Orlando, FL, Next Level Roofers is here to share practical information and tips to help you deal with your roof stain problem.


The most common cause of roof stains is algae growth due to the presence of moisture. Algae thrive in moist environments and, once established, can spread quickly across a roof. Moss, lichens and fungi can also develop on roofs when there is too much moisture or not enough sunlight reaching the surface. Bird droppings, tree sap and industrial pollutants are less common causes of roof stains, but they can still occur in certain conditions. 

Ways to Identify Roof Stains

Roof stains can be identified by their color and texture. Algae are typically black or dark green streaks, while moss is usually a darker green color with an uneven texture. Lichens have a yellowish-green hue and appear as crusty patches, while fungi can vary in color but generally appear slimy or spongy to the touch. Bird droppings are easily identifiable as they look like spots of white paint on the roof surface, while tree sap will be brownish with a sticky residue that can be difficult to remove. 

Removal Solutions

When it comes to cleaning solutions and methods, there are a few options available, such as:

Pressure Washing

Pressure washing is an effective way to remove roof stains, but it should only be done by a professional that does residential roofing services. Pressure washing can damage the shingles if done incorrectly, so it’s important to hire someone who has experience with this type of work around your area in The Villages, FL. 

Chemical Treatments

Chemical treatments are designed to kill algae, moss, lichens and fungi and should be applied after pressure washing for optimal results. Be sure to follow the instructions carefully when using any chemical treatment on your roof as improper use can lead to further damage.

Prevention Tips

The best way to prevent roof stains is to keep your roof clean and free of debris right after a new construction roof installation. Regularly inspect your roof for signs of damage and have it professionally inspected every so often to ensure that it’s in good condition. Also, make sure the gutters are clear of leaves or other debris so water can flow freely away from the house.
