A sturdy roof safeguards your family and belongings from harsh outdoor conditions. Keeping it in good shape can contribute to your home’s longevity and preserve your property’s value. Moreover, mold and algae are issues that can affect your roof’s appearance and integrity. Keep reading to learn the difference between these growths.
Roof algae often occur in humid climates. It appears as a black or greenish stain and thrives in moist environments. Asphalt shingles are more likely to have this growth because they contain limestone filler, which algae feed on. Gloeocapsa magma is the most common type of algae found on roofs. While primarily an aesthetic concern, this issue can accelerate shingle deterioration over time.
Treating and preventing algae involves regular roof cleaning. If roof algae are common in your area, it pays to invest in shingles that offer excellent resistance to this growth. Today, many manufacturers offer materials treated with algaecides, providing long-term protection against algae.
Does your roof have black, green or white patches? If so, you might be dealing with mold. Mold tends to grow in moist and shaded environments. It’s more likely to flourish in areas of the roof that receive little to no sunlight.
Regardless of its location, mold requires immediate attention. It produces spores that can cause allergic reactions, asthma attacks and other respiratory issues. Professional remediation can help ensure mold is completely eradicated and doesn’t return.
Algae is typically surface-level and more of an aesthetic issue. On the other hand, mold can infiltrate roofing materials, affect indoor air quality and pose health risks. Algae stains are usually uniform and can cover large areas, while mold might appear in patches with a fuzzy texture.
Addressing roof mold and algae starts with regular inspections and maintenance. Professionals can identify early signs of these issues before they cause significant problems. Thorough cleaning and treatment might eliminate algae. Meanwhile, mold growth might necessitate more extensive measures, including applying fungicides and replacing severely affected roofing components.
Ensuring adequate ventilation can mitigate mold and algae growth by reducing moisture buildup beneath the roof. Clean your gutters at least twice a year to reduce the likelihood of standing water. Trimming overhanging branches also helps prevent mold and algae by increasing the roof’s sunlight exposure.
