Let’s break down which approach makes the most sense for your home.
What Is Soft Wash Roof Cleaning?

Soft wash roof cleaning is a method that uses low pressure water combined with cleaning solutions to remove organic growth like algae, moss, and mildew. This process is designed to clean roofs without causing damage to shingles or roofing components.
In Merrillville and surrounding areas, black streaks on roofs are often caused by algae growth. Soft washing removes these stains while helping prevent them from returning.
- Low pressure application: Prevents shingle damage
- Specialized cleaning solutions: Break down organic growth
- Long lasting results: Helps delay future buildup
This method is widely recommended for asphalt shingles and other delicate roofing materials.
