Residential Exterior Cleaning Services

Black streaks on your roof are typically caused by Gloeocapsa magma — an airborne algae that feeds on limestone filler in shingles.

Left untreated, this growth:

• Retains moisture
• Accelerates shingle deterioration
• Reduces curb appeal
• Can shorten roof lifespan

Our soft wash roof treatment removes algae without damaging shingles or voiding warranties.

Most roofs look dramatically restored within hours.

Over time, siding develops:

• Green algae buildup
• Mold growth
• Oxidation (chalky residue on vinyl or metal)
• Pollen and environmental staining

OxyVanta safely cleans:

• Vinyl siding
• Hardie board
• Stucco
• Brick
• Painted surfaces

We adjust application methods for each material to ensure maximum restoration without risk.

Oxidation is the chalky white residue that forms on vinyl and painted aluminum surfaces.

Many companies avoid it because improper cleaning causes streaking and surface damage.

OxyVanta uses a controlled chemical process to safely lift oxidation and restore color clarity.

Concrete and pavers trap organic growth and staining.

We treat:

• Mold
• Algae
• Rust staining
• Organic discoloration

Our method penetrates porous surfaces to remove buildup rather than simply blasting the top layer.

Yes — when professionally formulated and applied.

High pressure can:

• Strip granules from shingles
• Force water under siding
• Crack stucco
• Damage painted finishes

Soft washing treats the cause — not just the surface.

Most residential roof treatments last 2–5 years depending on environment, shade, and moisture exposure.

Siding and surface treatments typically maintain appearance for 1–3 years.

Every home is different — but the transformation is often dramatic.
