• Targets biological growth
• Reduces damage risk

Pressure Washing

• It uses high-pressure water
• Helps removing surface dirt
• Better suited for hard surfaces
• May damage roofing materials
• It can shorten the roof lifespan if used improperly

For roof maintenance, soft washing is considered the safer option.
