Roof Moss Myths Every Vancouver Homeowner Should Stop Believing

The Problem with Misinformation

If you live anywhere along the Lower Mainland, you’ve likely heard one of these lines:
“A little moss adds character.”
“You can just blast it off with a pressure washer.”
“The rain will take care of it.”
None of these are true—and believing them costs homeowners thousands of dollars each year.

The Real Cost

Moss doesn’t just sit on your roof; it traps moisture and lifts shingles. In damp areas like North Vancouver or Port Moody, that moisture seeps under flashing, rots decking, and shortens roof life by up to a decade. Insurance companies increasingly deny water-damage claims linked to moss neglect.

The Right Way to Handle Moss

Professional removal uses a dry-cleaning method followed by a biodegradable inhibitor that halts regrowth without damaging shingles. Clean Break’s crews use low-pressure systems and roof-safe access gear compliant with WorkSafeBC standards—no scraping, no torn granules, no risk.

When to Schedule Treatment

The ideal times are late spring and early fall. Treating once the roof is fully dry allows cleaning agents to work effectively, while a fall follow-up keeps growth from returning through winter’s humidity.

The Takeaway

Moss is not cosmetic; it’s structural. Preventative care every 12–18 months protects your home and your warranty.
