Yes — power washing can remove moss, but the long-term success depends entirely on using the correct method. Moss is a resilient, root-based organism that embeds itself deep into porous surfaces like asphalt shingles, concrete, pavers, and brick. Simply blasting moss with high pressure will remove the green layer you can see, but it will not kill the root structure, causing it to grow back quickly and potentially even thicker.
This is why professional contractors listed on PowerWashing.com rely on soft washing, not high-pressure washing, to eliminate moss safely and permanently.
Below is the complete breakdown of how moss removal works — and why the wrong approach can cause expensive damage.
⭐ 1. High Pressure Only Removes Surface Moss — Not the Root
Moss attaches itself to surfaces with a root-like anchoring system called rhizoids. When you use high pressure:
Repeated blasting can erode concrete, pit pavers, and strip granular coating from roof shingles.
High pressure is NOT a safe solution for moss removal.
⭐ 2. Soft Washing Is the Proper Method to Remove Moss
Soft washing uses:
These cleaning agents penetrate moss and destroy it from the inside out, including the root structure.
This method is safe for:

Moss on roofs is extremely common in damp, shaded, or cool climates. It holds moisture like a sponge, causing:
Roof manufacturers strictly recommend soft washing, never pressure washing.
Contractors found through PowerWashing.com follow these roofing standards to avoid voiding warranties and causing structural issues.
⭐ 4. Moss Returns Faster When Removed Incorrectly
If moss is pressure washed:
By contrast, soft washing leaves a residual solution that prevents regrowth for 12–24 months, depending on climate.
⭐ 5. Moss Loves Certain Property Conditions
Moss grows aggressively in areas with:
PowerWashing.com contractors evaluate these conditions and recommend appropriate maintenance.
⭐ 6. Should Moss Be Removed Every Year?
Not always.
With proper treatment:
Routine maintenance keeps moss from taking root again.
⭐ 7. DIY Moss Removal Is Risky
Common mistakes include:
Instead, hiring a trained professional from the PowerWashing.com Directory ensures your moss problem is treated safely, effectively, and without causing damage.
