Roof Soft-Washing: Safe Algae Removal Without Damage

Roof Soft-Washing: Safe Algae Removal Without Damage

Helpful Hand Property Services•3 min read

Those dark roof streaks are usually Gloeocapsa magma algae. High pressure can strip granules and void warranties—soft-washing cleans safely and restores curb appeal.

Why Soft-Wash Beats High Pressure on Roofs

• Protects shingles: low pressure won’t dislodge granules
• Targets algae: detergents break down organic growth for a longer-lasting clean
• Safer for flashings & vents: no water forced under shingles

Our Roof Soft-Wash Steps

• Property & landscaping pre-wet
• Detergent applied at low pressure
• Controlled dwell time, then gentle rinse
• Final plant rinse & site walk-through

How long does it last?
Most roofs stay clean 3–5 years depending on shade and moisture. Pair with a house wash for a full refresh.

FAQ: Is the solution plant safe?

We pre-wet, control runoff, and perform a post-rinse on landscaping. We also use catch/rinse methods near sensitive beds.

FAQ: Will I see immediate results?

Yes—stains lighten dramatically during service; some residual spotting can fade further over several rains.
