Roof Washing in Rensselaer, NY

Black streaks, green growth, and moss buildup are common in Rensselaer, especially on shaded roof sections and north-facing slopes. A proper roof wash cleans it up without blasting granules off your shingles.

We use a soft wash process designed for roofs. The cleaning does the work, not high pressure. You get a cleaner roof, stronger curb appeal, and a result that lasts.

Rensselaer Roof Washing Built for Black Streaks, Valleys, and Moss-Prone Shade

In Rensselaer, black roof streaks and green growth are common on shaded roof faces and north-facing slopes. Valleys and roof transitions collect leaves and organic debris, which keeps shingles damp and feeds algae, moss, and lichen. 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.
