THE REAL PROBLEM (Story & Diagnosis)
Is Your Roof Failing — Or Does It Just Need a Proper Cleaning?
If your roof looks dark, weathered, and covered in green moss, you might assume it’s time for an expensive replacement. That’s exactly what a Beaverton homeowner thought last fall after a contractor quoted her $15,000 for a new roof, while a neighbor brushed off the dark streaks as harmless dirt.
In reality, neither diagnosis was accurate. What appeared to be a failing roof was actually an infestation of Gloeocapsa magma algae and moss- a Pacific Northwest staple that thrives in our damp, shaded climate. A roof that looks completely worn out often has years of life remaining once properly treated. AJS Power Wash Pro specializes in identifying and treating organic growth to help extend the life expectancy of your roof.
UNDERSTANDING THE THREAT
ALGAE VS. MOSS VS. TANNIN STAINS
WHY HIGH PRESSURE DESTROYS ROOFS
(And Why Soft Washing is the Solution)
Comparison:
Standard High-Pressure Washing (What You Must Avoid):
- Blasts away protective ceramic asphalt granules, cutting your roof's lifespan in half
- Can void manufacturer warranties and damage fragile ridge caps
- Only tears off surface moss tops while leaving active root spores embedded in the shingle
- Risks forcing pressurized water underneath shingles into the sub-roof and attic
- Comparison -
AJS Dedicated Soft Wash Method (Shingle-Manufacturer Approved):
- Uses gentle, garden-hose-level water pressure that never harms shingles or tiles
- Asphalt Shingle Roofs: Safe soft washing that preserves aggregate granules and manufacturer warranties.
- Concrete & Clay Tile Roofs: Low-pressure application protecting delicate mortar lines and ridge caps without walking on fragile tiles.
- Applies a specialized, Eco-friendly solution that breaks down organic growth at the molecular level
- Kills 100% of moss, algae, and lichen spores down to the root
- Keeps roofs clean 3x longer (typically 1 to 3 years in the Pacific Northwest)
- Gutter & Downspout Systems: Complete debris extraction, downspout flushing, and flow verification to prevent winter ice dams and foundation flooding.
- Landscape Protection: Comprehensive fresh-water soaking of all surrounding lawns, shrubs, and gardens before, during, and after service.
