Pressure washing roof is the process of using a high-pressure water spray to clean dirt, grime, moss, algae, and other debris from the surface of a roof. This technique is commonly employed to maintain the appearance and extend the lifespan of roofs, particularly those made of materials like asphalt shingles, tile, or metal. Pressure washing can effectively remove stains and organic growth, restoring the roof’s original color and enhancing its overall curb appeal.
