Lichen Low Pressure Washing
Lichen Removal
Lichens on your roof can be a cosmetic blemish and a significant structural concern.
If you think you may have lichens on your roof, the professionals at Stewart
Painting are here to help. We perform a low pressure wash treatment to revive your
roof without damage, giving you the best results possible. The dying lichen will turn
from green to white indicating that the Lichen is dead. Overtime (6-12 months) as
the root system dies and dries up the Lichen will fall off. Streaks from dying lichen
will fade over time as lichen continues to dry up.
What Are Lichens?
Lichens are a living organism, a combination of algae and fungus. They come in
various sizes and forms, but lichens typically appear in white, light blue or green
coral-like spots on your roof.
Lichens latch onto your roof and deteriorate your shingles. They trap humidity that
accelerates wear and tear, and they can cause your roofing material to warp or
crack in cold weather.
Why Not High Pressure Wash?
Wood shingles: High pressure wash will also remove dead wood fibers which helps
protect the shingle from rapid aging. It can also scar the wood.
Asphalt shingles: High Pressure wash can remove the Lichen but also will remove
colored granules, leaving the black base of the asphalt shingle visible.
