Roof Stains: What They Are and How to Get Rid of Them

A roof stain is a discoloration on the surface of a roof that can occur for several reasons. These stains are caused by algae, moss, and other contaminants that accumulate over time. In Sherwood, they are more common due to the humid climate and may often require special cleaning solutions to remove effectively. This blog post will provide an overview of what causes these stains, how to get rid of them, and how to prevent future buildup from occurring.

Examples of Roof Stains

Roof stains typically appear as dark streaks or patches that can make your roof look dingy and unattractive. The most common types of roof stains include:

• Algae stains – These tend to be black and may have a greenish tinge when viewed up close.
• Moss stains – These usually appear as darker green streaks.
• Lichen stains – This type of stain is often light gray with wispy-like streaks.

Causes of Roof Stains

The main cause of roof stains is the accumulation of moisture on your roof. Moisture creates the perfect environment for algae, moss, and other organisms to thrive. Other causes can include acid rain or bird droppings, which contain acids that can stain your roof’s surface. In addition, dark shingles are more prone to staining due to their ability to absorb heat and retain moisture.

How to Get Rid of Roof Stains

There are several methods you can use to get rid of stains on your roof. The most common include: 

• Cleaning solutions – Using specially formulated cleaning solutions can help remove surface buildup without damaging your roof.
• Pressure washing – Pressure washing your roof with a low-pressure setting can help loosen and remove stubborn stains.
• Professional roof cleaning – If the stain is more severe or difficult to remove, then professional roof cleaning done by a reputable roofing contractor may be necessary to fully eliminate it.

How to Prevent Roof Stains

Whether you have commercial or residential roofing, the best way to prevent future staining is by regularly inspecting and maintaining your roof’s condition. If possible, try installing zinc strips along the ridge line. This will naturally inhibit algae growth due to its chemical properties when wetted by rainwater runoff from the shingles above it. Additionally, you should have a professional residential and commercial roofing contractor inspect your roof every few years to catch any potential issues before they become more serious.
