why is my shingles algae growth

Roofing

The answer to 'why is my shingles algae growth' is that algae growth on asphalt shingles is a common problem, especially in humid or damp climates. Algae feed on the organic materials in the shingles and can cause discoloration, streaking, and overall unsightly appearance. This is often a cosmetic issue, but can lead to more serious problems if left unchecked.

Algae growth is typically caused by a combination of moisture, shade, and organic debris on the roof. Roofs that are in constantly damp or shaded areas are more prone to algae buildup. Over time, the algae can cause the shingles to degrade and reduce their lifespan. In some cases, severe algae growth can even lead to leaks or other roof damage.
