Question: Can algae growth damage asphalt roofing?
Top Answer (66% of 45 votes): Yes.

Answer: In some cases
Explanation: Algae growth on asphalt roofing is mostly a cosmetic issue, but in some cases it can contribute to damage over time. Algae itself does not typically break down shingles, but it can hold moisture on the surface, which may lead to faster deterioration in certain conditions. In more severe or long-term cases, algae growth can also create an environment that encourages moss or lichen, which can lift shingles and cause granule loss or moisture intrusion. Regular maintenance and cleaning can help prevent these issues and extend the life of the roof.

Answer: Yes
Explanation: Yes, algae growth slowly feed off the asphalt's limestone. This weakens the roof's structural integrity, which may cause some shingles to detach. Damage from algae may also weaken your roof's ability to reflect sunlight, causing more heat to radiate throughout your home.
