Professional roof washing removing algae and black streaks from asphalt shingles

Our Services

Professional Roof Washing

Remove black streaks, algae, moss, and lichen from your roof without voiding your warranty or damaging shingles.

Those dark black streaks on your roof aren't just ugly — they're a living organism called Gloeocapsa magma, a type of algae that feeds on the limestone filler in asphalt shingles. Left untreated, algae, moss, and lichen break down your shingles, trap moisture, and shorten your roof's lifespan by years. Our professional roof washing service uses the ARMA-recommended soft wash method to safely eliminate organic growth and restore your roof's appearance without a single shingle of damage.

What Roof Washing Removes

From black algae streaks to moss and lichen — we eliminate every type of organic growth safely.

Black Streak Removal

Eliminate Gloeocapsa magma algae — the cause of those dark streaks — from asphalt shingles safely and completely.

Moss & Lichen Treatment

Kill and remove moss and lichen that trap moisture and cause shingle deterioration and rot.

Warranty-Safe Method

We use the ARMA-recommended low-pressure soft wash technique — no high-pressure blasting that voids manufacturer warranties.

Long-Lasting Results

Our biodegradable treatments kill growth at the root, keeping your roof cleaner for 2–4 years after a single treatment.

Why We Never High-Pressure Wash Roofs

High-pressure washing strips the protective granules from asphalt shingles, voids manufacturer warranties, and can force water under shingles causing leaks. The Asphalt Roofing Manufacturers Association (ARMA) recommends low-pressure soft washing — and that's exactly what we use on every roof we clean.

Our Roof Washing Process

Safe, methodical, and thorough — every time.

1

Roof Inspection

We assess the type and extent of growth, shingle condition, and any areas needing special attention before we begin.

2

Landscape Protection

We pre-wet all surrounding plants, shrubs, and landscaping to protect them from cleaning solution runoff.

3

Soft Wash Treatment

Our biodegradable cleaning solution is applied at low pressure, penetrating and killing algae, moss, and lichen at the root.

4

Rinse & Final Check

We rinse the roof and surrounding areas thoroughly and inspect every section to confirm complete removal.
