Why Moss Is Hard on Your Roof

Moss holds water against your shingles like a sponge, lifts their edges, and sends debris straight into your gutters. Left alone it shortens the life of your roof, and a roof replaced early is one of the most expensive repairs a homeowner can face.

Our Roof Moss Treatment

We remove heavy moss by hand with soft tools, then apply a moss-killing treatment at low pressure. Whatever is left dies off and washes away with the rain over the following weeks. Black streaks from algae are lifted with a gentle soft wash, never a pressure washer.

Gutters Cleared When We're Done

Moss that comes off the roof ends up in the gutters. We clear the gutters and flush the downspouts after every roof treatment so water keeps moving away from your home.

FAQ

Common Questions

Do you pressure wash roofs?

No. High pressure can strip granules and lift shingles. We use hand removal and a low-pressure treatment instead.

How long until the moss is gone?

Heavy moss comes off the day we visit. The treatment kills what remains, and it continues to wash away with the rain over the next few weeks.

How often should I treat my roof?

Most Kootenay roofs benefit from a moss treatment every one to two years, especially on shaded or north-facing slopes.

Is the treatment safe for my gardens?

Yes. We pre-wet and protect landscaping below the roofline and rinse it after treatment.
