How can moss be removed from asphalt shingles?

Brushing is an effective method for removing moss from asphalt shingles because it allows for controlled and gentle removal without causing damage to the shingles. Using a soft-bristle brush helps to dislodge moss from the surface of the shingles without risking the integrity of the roofing material. This method also minimizes the potential for water infiltration that can occur with more aggressive techniques.

Additionally, brushing moss off can help prevent further damage to the shingles or the underlying structure, which could happen if harsh chemicals or high-pressure washing were employed. Chemicals may potentially harm the shingles over time, and high-pressure washing can remove granules and compromise the protective coating of the shingles, leading to premature aging or leaks. Scraping with a tool can also be too abrasive, risking further damage to the surface.
