How to Prevent Mold on Your Roof

Mold is one of the most troubling issues a homeowner can face. Not only is it unsightly, but it could also be a significant health risk for your family. Mold grows in places where moisture is trapped, and it can spread quickly. Because your roof is regularly exposed to wind and rain, it can be a high-risk place for mold growth. Learn how to prevent mold on your roof, and contact our team at RoofBoyz, LLC, for an inspection! Our experienced contractors will ensure that your roof is in top condition. 

The Most Common Type of Roof Growth 

The most common type of growth found on roofs is technically not a mold at all—it’s an algae called Gloeocapsa Magma. This type of growth is spread through the air and causes dark streaks on your roof as a result of dirt, humidity, and moisture. It also needs nutrients to grow, which it can get by consuming the limestone filler of your shingles.  

This type of algae will spread quickly over your roof, and by consuming the limestone filler, it deteriorates your shingles. Compromised shingles make it easy for rain and wind to damage the interior materials of your roof, which can later lead to other mold and mildew. If this occurs, you’ll want to repair your shingles as quickly as possible. 

Identifying Mold and Mildew On Your Roof 

If you notice mold on the exterior of your roof, it’s often a sign that mold has been growing on the inside of your roof as well. That being said, one of the best ways to prevent the growth of mold and mildew is through preventative care. Being proactive and investing in roof cleanings a few times a year can help significantly. Keep in mind that cleaning a roof, especially one that has a significant mold or mildew problem, should always be left to the professionals. 

Other Prevention Tips 

Along with routine cleanings, there’s more that homeowners can do to prevent the growth of mold and mildew on their roofs. Some options include: 

• Trimming tree branches. You can allow more sunlight to reach the roof by trimming back tree branches. The more sunlight that a roof has, the less opportunity for mold and mildew to grow.  

• Clearing debris. Remove debris from your roof using a non-abrasive method such as a leaf-blower. Wet leaves and debris that sit on a roof for an extended period of time can be a breeding ground for mold.  

• Keeping the gutters clean. This helps encourage water drainage. Clear and efficient gutters prevent water from backing up onto your roof or sitting stagnant in one spot.  

• Upgrading your shingles. Look into using algae-resistant asphalt shingles, or add zinc or copper strips to your roof to prevent both algae and moss.
