MOSS ISN'T DIRT. TREAT THE GROWTH.

Roof moss removal on Salt Spring Island is not about scraping or blasting. Moss is a living organism that anchors to shingles and thrives in the island's wet, shaded conditions. The correct approach treats the organism and lets it release naturally.

DON'T SCRUB IT.

TREAT IT.

Scrubbing moss off a roof removes the visible growth but leaves root structures behind and damages the shingle surface. Wire brushes tear granules off asphalt shingles. High-pressure washing forces water under shingles and into the roof structure.

Treatment targets the moss at the biological level. The organism dies, its bond to the surface weakens, and natural weathering lifts the dead growth away over the following weeks and months.

WHAT WE DON'T DO

  • No aggressive roof scrubbing
  • No scraping with metal tools
  • No wire brushes on shingles
  • No high-pressure roof washing
  • No one-size-fits-all approach

THE TREATMENT PROCESS

IDENTIFY. TREAT. DIE-OFF. RELEASE.

The moss is identified and the roof surface assessed. Treatment is applied at low pressure with the correct concentration for the growth type and roof material. The moss dies over the following days and weeks.

Lighter growth can progressively release through subsequent weather exposure. Established moss progressively weakens, loosens, and releases. Heavier treated growth may progressively break down and can require more time or follow-up. No exact timeline is promised because every roof and every growth pattern is different.

SALT SPRING CONDITIONS

Properties with heavy tree cover, north-facing roof sections, or coastal exposure tend to see faster moss establishment. Shaded roof sections can stay damp longer, creating ideal conditions for moss anchoring.

Tree-covered properties may accumulate organic debris — needles, leaves, branches — that retains moisture and feeds biological growth. The assessment considers these factors before any treatment is applied.

RAINWATER COLLECTION

TELL US BEFORE TREATMENT.

Properties on Salt Spring Island that use roof runoff for rainwater collection require that information to be identified during assessment so the treatment plan can account for the collection system and applicable product or manufacturer requirements.

Do not assume treatment chemistry is safe for potable-water systems without specific verification. Do not follow universal tank-disconnection or reconnection timing unless supported by the specific product instructions and treatment protocol.
