Maintaining your roofing system properly helps it last for its typical useful life, which might be 20 years. Keeping the roof clean is an important part of an effective maintenance routine. Here is what you need to know to protect your roof from growth that can cause damage. 

Types of Roof Growth

If you see a blackish-green growth on your roof, it may be algae. This fungus thrives on moisture, starts growing on wet spots on shingles, and spreads quickly. Mildew, another growth, is pink, light gray, or black and establishes itself rapidly in wet and warm environments. 

If your roof is in shade and holds moisture, dirt, and debris, it provides an environment for moss to grow. While you might find this plant attractive, moss can cause problems.

The most dangerous fungus is mold, which creates health hazards, such as breathing difficulty and skin irritation. Mold growth is black, dark green or brown, and it is slimy with a strong odor. You find it thriving in moist, warm conditions, and on roofing materials, including wood shingles and drywall. 

How They Affect the Roof

Untreated algae growth is unattractive and can cause permanent stains. Mold and mildew eat away at roofing shingles. Moss traps moisture in your roof, allowing the water to seep into your home's structure, which can lead to dry rot. 

Prevention Tips

To reduce the moisture that roof growth needs to thrive, ensure your roofing has an effective drainage system. Adjust your attic venting so that it does not trap heat, which can allow moisture to remain. Don’t leave moss, mildew, or mold unattended on your roof. One option is purchasing a ready-made roof cleaning solution. Or, for a do-it-yourself cleaner, put on rubber gloves and a protective mask, and mix equal parts of bleach and water in a bucket. Pour the solution into a pump sprayer and clean the roofing with it gently to protect the surfaces and kill fungus.
