why is my architectural shingles algae growth

Roofing

The answer to 'why is my architectural shingles algae growth' is that algae growth on architectural shingles is a common problem caused by moisture, shade, and environmental conditions. Algae can discolor and degrade the shingles over time, leading to an unsightly appearance and potentially reducing the lifespan of the roof.

Algae growth is often more prevalent in humid or damp climates, on roofs with significant shade from trees or other structures, and on north-facing slopes that don't receive as much direct sunlight. The algae feed on the limestone filler in the shingles, breaking down the material and causing discoloration.
