Many homeowners assume that more pressure equals better cleaning. When it comes to roofs, the opposite is true. Here is why soft washing is the professional standard for roof cleaning.
What is the Difference?
Pressure washing uses high-pressure water (1,500-3,000+ PSI) to blast away dirt. Soft washing uses low pressure (under 500 PSI) combined with professional-grade cleaning solutions to kill and remove biological growth at the source.
Why Soft Washing is Better for Roofs
- Preserves shingle granules that protect against UV and weather
- Will not void your roofing manufacturer warranty
- Kills moss, algae, and lichen at the root – preventing faster regrowth
- Results last 4-6 years vs. 1-2 years for pressure washing
- Safe for all roof types including asphalt, cedar, and tile
When is Pressure Washing Appropriate?
Pressure washing is excellent for hard surfaces like concrete driveways, sidewalks, patios, and retaining walls that can withstand high pressure. For these surfaces, it provides a thorough, fast clean.
