Fungi and Mold
3. The Hidden Dangers of Fungi
Algae isn’t the only microscopic menace that can darken your roof. Fungi, including mold and mildew, also play a significant role. Unlike algae, which can photosynthesize their own food, fungi are decomposers. They feed on organic matter, and unfortunately, your roof can provide a buffet of tasty treats like decaying leaves, twigs, and even the asphalt itself.
Mold and mildew often appear as dark, fuzzy patches on shingles. They thrive in damp, shaded areas, just like algae. But unlike algae, they can penetrate deeper into the shingle material, causing more significant damage over time. This can lead to shingle deterioration, granule loss, and ultimately, leaks. And nobody wants a leaky roof!
Identifying fungi can be tricky because it often blends in with other types of staining. However, if you notice a raised, textured growth on your shingles, chances are you’re dealing with a fungal infestation. Ignoring the problem won’t make it go away. In fact, it will only get worse as the fungi continue to spread and consume the organic matter on your roof.
Preventing fungal growth involves keeping your roof clean and free of debris. Regularly removing leaves, branches, and other organic material will deprive the fungi of their food source. Trimming back overhanging trees can also help increase sunlight and ventilation, making it less hospitable for these unwanted guests. Consider professional roof cleaning to remove existing fungi and prevent future growth. Remember, a proactive approach is always the best defense!
