Roof Moss Treatment, Done Right

Moss loves a North Idaho roof. Shade, moisture, and long wet seasons let it spread across north-facing slopes and along the shaded edges of almost every home. Left alone, it lifts shingles, holds water against the roof deck, and takes years off the life of your roof. It's also the first thing an inspector or buyer notices.

The wrong fix does more damage than the moss. Pressure washing a roof strips the protective granules off asphalt shingles, and scraping tears them. We treat instead: a professional moss and algae treatment is applied at low pressure, the moss dies, and over the following weeks rain and wind shed it off naturally. The roof comes clean without anything abrasive ever touching it.

What We Clean

  • Asphalt & architectural shingle roofs
  • Metal roofs
  • Composite & synthetic shake
  • Concrete & clay tile
  • North-facing & shaded slopes
  • Heavy debris removal before treatment
  • Gutter clean-out add-on
  • Annual maintenance treatments
How It Works

Our Roof Moss Treatment Process

Straightforward, thorough, and the same every time.

01

Inspect the roof

We look at moss coverage, roof type, and condition, and remove heavy debris and clumps by hand where needed.

02

Protect the surroundings

Landscaping is pre-wet and downspouts are managed so runoff doesn't reach your plants.

03

Apply the treatment

The treatment goes on at low pressure and begins killing moss, algae, and lichen immediately.

04

Let the weather finish

Dead moss loosens and sheds off with normal rain and wind over the following weeks. No scraping, no pressure.

What Customers Say

Reviews From Real Jobs

Straight from customers across North Idaho and the Inland Northwest.

★★★★★

“I opened my gym business in an abandoned auto shop, and the floors were covered with decades of soot and grease. Joey pressure washed the entire floor of the gym and got the concrete incredibly clean. The space had a terrible smell, and after he was done, it was completely gone. I couldn’t recommend Joey enough for pressure washing, window cleaning or any other outdoor job.”

Questions

Roof Moss Treatment FAQ

The questions we hear most. Don't see yours? Call or text and ask.

Will you pressure wash my roof?

No — and you shouldn't let anyone do it. High pressure strips the granules that protect asphalt shingles from UV and water. Treatment gets the same result without the damage.

How long until the moss is gone?

It starts dying within days and typically sheds off over the next several weeks with rain and wind. Heavier growth can take a full season to fully clear.

Is the treatment safe for my roof and my plants?

Yes. It's applied at low pressure and is safe for shingle and metal roofs. We protect landscaping before and after application.

How often should I treat my roof?

An annual treatment keeps moss from ever getting established again. Once a roof is clean, maintenance treatments are quick and inexpensive compared to the first one.
