Your roof should be in good shape to effectively protect your home from the elements. Excess indoor and outdoor humidity can affect this part of your home. It can trigger the development of organic growths, such as algae and mold. Both of these issues can harm your roof’s appearance and stability.
A leading roof repair company discusses the difference between roof mold and algae.
What Does Roof Mold Look Like?
Roof mold manifests as black or dark green streaks and can spread quickly across the system. It isn’t just a cosmetic issue; it can cause significant damage if left untreated. Mold usually grows and thrives in moist environments. Over time, it can speed up the degradation of roofing materials.
What Is Roof Algae?
Algae growth on roofs typically looks like dark spots. It’s more common in areas with high humidity and frequent rains. Gleocapsa magma is a cyanobacteria that feeds on limestone filler in asphalt shingles. While algae is primarily an aesthetic issue and not as harmful as mold, it can cause your home’s appearance to suffer. It can also shorten your roof’s lifespan by retaining moisture on shingles.
How Do You Deal With Them?
Regular roof cleaning and maintenance can help combat mold and algae. Professionals will thoroughly assess mold-affected areas before recommending the best course of action. The mold removal process involves careful cleaning and repairs or replacement of severely damaged components. Experts use specialized cleaning agents to eliminate algae without damaging your roof.
Preventive measures are also crucial to keep mold and algae at bay. This can include routinely cleaning gutters to prevent water accumulation and installing zinc or copper strips to inhibit algae growth. Keeping nearby trees trimmed can also increase sun exposure to your roof, which can discourage algae development.
