Roof Washing in Nassau, NY

If your roof has black streaks, green growth, or moss building up in valleys and shaded sections, you are not alone in Nassau. Between tree cover and damp pockets, organic growth shows up fast and makes a roof look older than it is.

We use a roof-safe soft wash process. The cleaning does the work, not pressure, so you get a clean roof without stripping granules or forcing water where it does not belong.

Nassau Roof Washing Built for Mossy Valleys, Shade Lines, and Black Streaks

In Nassau, organic growth shows up fast because tree cover and damp pockets keep roof faces wet longer after rain. Black streaks (algae) usually spread down from ridge lines, and moss builds up in valleys and roof transitions where leaves sit and hold moisture. We clean roofs using a low-pressure approach based on soft wash so shingles and roof components are treated without high-pressure impact.

Our Roof Washing Process

1) Roof inspection and jobsite protection

We confirm roofing material, pitch, access, and staining severity. We protect landscaping and plan runoff control. Common prep questions are covered on FAQs.

2) Soft wash treatment

We apply a roof-safe cleaning solution using low pressure to treat algae, moss, and lichen so we are not relying on aggressive pressure to “blast” stains off shingles.

3) Controlled rinse and final check

We rinse carefully and verify consistent results across roof faces, valleys, flashing lines, and shaded sections, then complete a final check of the property. See recent work on our work.
