Understanding Roof Contaminants: Mold, Mildew, and Algae

Homeowners often face the challenge of dealing with unsightly and potentially damaging mold, mildew, and algae on their roofs. These contaminants not only mar the aesthetic appeal of your home but can also lead to long-term damage if not addressed promptly. Identifying these elements is the first step in maintaining a healthy roof. Typically, dark streaks or stains on the roof are indicative of algae, particularly Gloeocapsa Magma, a type of blue-green algae. This algae, along with mold and mildew, thrives in moist environments and can be transported to your roof through various means, including birds, wind, and nearby vegetation.

Safe and Effective Removal Methods

When it comes to removing these unsightly elements from your roof, safety and effectiveness are paramount. While some homeowners may consider this a DIY task, it is advisable to seek professional assistance for optimal results and safety. MaxForce Roofing and Siding LLC, based in Columbus, OH, emphasizes the importance of professional intervention in such cases. Their expertise ensures that the removal process is conducted safely and effectively, preventing any potential mishaps or further damage to the roof.

DIY Approaches: Caution and Care

For those who prefer a hands-on approach, there are several methods to consider. However, it’s crucial to proceed with caution to avoid accidents and further damage to the roof. Here are some recommended techniques:

Specialized Cleaning Products: Products like Wet and Forget or Spray and Forget, available at hardware stores, are designed specifically for roof cleaning. These can be easily attached to a hose, sprayed onto the affected area, and left to work their magic.

Oxygen Bleach Solution: A mixture of oxygen bleach cleaner and water in equal parts can be an effective solution. This can be sprayed or gently poured over the algae-infested areas. After allowing it to sit for about 30 minutes, it can be rinsed off with a hose.

Professional Assistance: A Safer Alternative

Despite the availability of DIY methods, the safest and most effective way to deal with roof contaminants is to engage professional services. Companies like MaxForce Roofing and Siding LLC offer specialized expertise in roof maintenance and cleaning. They can conduct a thorough inspection and provide tailored solutions that ensure the longevity and integrity of your roof.

Why Avoid Pressure Washing

A critical piece of advice for homeowners is to avoid pressure washing the roof. This method can cause irreversible damage to the shingles and compromise the roof’s structural integrity. The high pressure can strip away granules from the shingles, leading to premature aging and vulnerability to the elements.


Maintaining a clean and healthy roof is essential for the longevity and aesthetic appeal of your home. Understanding the nature of roof contaminants and the best methods for their removal is crucial. While DIY methods exist, seeking professional help, such as from MaxForce Roofing and Siding LLC, ensures safety and effectiveness. Remember, preserving your roof’s integrity is key to protecting your home.
