Moss accumulation on shingles and tiles causes more long-term structural damage and underestimated issues a property can encounter. In moisture-rich climates, including the Lake Oswego, OR area, moss develops on roofs quickly — and without a proper removal and prevention program, it significantly damages roofing materials that leads to premature roof failure.
Mossaway Roof Moss Removal is a specialized exterior cleaning company working only on moss and lichen removal and prevention for properties throughout the country. Mossaway provides the biology-based removal approach that actually solve the moss problem.
Why Moss Is More Dangerous Than It Looks
Moss growing on shingles or tiles traps water against the surface below, accelerates shingle granule loss, gets under tile edges, and sets the stage for leaks and accelerated material breakdown.
Property owners in Lake Oswego, OR who can see any growth on their roof, prompt professional removal is essential — before damage compounds.
How Mossaway Removes Moss Safely
Our removal method uses soft wash technique paired with biological moss-killing chemistry rather than high-pressure washing, which causes surface damage and risks cracking tile or dislodging slate. Once the moss is treated and removed, our team places zinc or copper ridge strips along the ridge — these metals leach trace ions downward with rainfall that inhibits moss regrowth for years after installation.
