Protect Your Home's Warranty
Manufacturer Approved
Major shingle and siding manufacturers specifically recommend soft washing over high-pressure methods.
Protect Assets
Don't risk losing a 30-year roof warranty over a single afternoon of improper "power" washing.
Hidden Dangers
High pressure can force water behind your siding, creating a perfect environment for structural mold.
Long-Term Value
A professionally soft-washed home maintains its value and stays cleaner up to three times longer.
Is Pressure Washing Voiding Your Warranty?
Most homeowners think they are doing the right thing by "power washing" their home every spring. However, if you own a home with asphalt shingles or vinyl siding, that high-pressure stream of water might be costing you thousands of dollars in hidden ways.
The ARMA Standard for Roofs
The Asphalt Roofing Manufacturers Association (ARMA)—the people who actually make your shingles—specifically warns against high-pressure washing.
The Damage: Pressure washers blast away the protective ceramic granules.
The Consequence: Once those granules are gone, your roof loses its UV protection and fire resistance.
The Fine Print: If you have a 30-year warranty and a contractor uses high pressure, the manufacturer can deny any future claims for leaks or premature wear.
Vinyl Siding and "Thermal Shock"
Vinyl siding is designed to be weather-resistant, but it isn't designed for 3,000 PSI at close range.
Water Intrusion: High pressure can force water behind the siding panels, leading to trapped moisture and hidden mold growth in your wall cavities.
Cracking: In cooler temperatures, high-pressure water can cause "thermal shock," leading to brittle siding that cracks or chips
Soft Washing: The Warranty-Safe Alternative
At Blue Heron, we follow the cleaning protocols established by the manufacturers. By using a soft wash system, we ensure:
Zero Granule Loss: We use chemistry, not force, to remove stains.
No Water Intrusion: Our "low-pressure" system is no stronger than a heavy rainstorm.
Manufacturer Compliance: Your 25- or 30-year warranty stays fully intact.
