Cedar Shake Roof Cleaning & Restoration
Cedar shake and cedar shingle roofs are one of Long Island's most distinctive architectural features — especially across the Hamptons, North Shore estates, and older Suffolk County neighborhoods. They're also one of the most misunderstood when it comes to cleaning.
Never pressure wash a cedar roof. High pressure splits the shakes, strips the natural oils, and accelerates the very decay you're trying to prevent. H2Only uses a purpose-built low-pressure soft wash system — under 100 PSI — with biodegradable detergents formulated for wood surfaces.
We kill moss, lichen, algae, and mildew at the root without touching the cedar fiber structure. After cleaning, we apply a cedar-safe biocide treatment to inhibit regrowth. A well-maintained cedar roof lasts 30–50 years — a neglected one may need replacement in 15–20.
