Kill the streaks. Save the shingles.

    Roof cleaning that extends your shingles' lifespan.

    Those black streaks aren't dirt — they're algae eating your shingles. I use the ARMA-approved soft wash method to kill the growth, restore the color, and buy back years of roof life.

    What's included

    • Asphalt shingle cleaning (black streak removal)
    • Metal and tile roof cleaning
    • Moss and lichen treatment
    • Algae and mildew kill with biodegradable solution
    • Gutter and downspout rinse
    • Adjacent landscaping protection

    Best for

    • Roofs with visible black streaks or staining
    • Homes under tree canopy or near water
    • Pre-sale curb appeal prep
    • Insurance or HOA inspection prep
    • Roofs 5+ years old that have never been cleaned
    • Homeowners considering premature roof replacement
    The Process

    How it works

    Straightforward. No hidden fees, no bait-and-switch.

    01

    Roof Assessment

    I inspect the shingle condition, flashing, and any fragile areas before determining the right approach and detergent dilution.

    02

    Soft Wash Application

    Low-pressure application of the industry-standard algae-killing solution. No walking on shingles, no high-pressure damage.

    03

    Rinse + Runoff Control

    Gentle rinse moves dead organic matter into the gutter system. I pre-rinse and monitor landscaping so runoff doesn't harm plants.

    Never let anyone pressure-wash your roof. High pressure tears the granules off asphalt shingles and voids most manufacturer warranties. The ARMA (Asphalt Roofing Manufacturers Association) recommends soft washing — that's what I do. Kill the algae, protect the warranty.
