ROOF CLEANING IN SNOHOMISH & KING COUNTY

Top-Rated Roof Moss Removal & Cleaning

Moss and black streaks gone, the safe way, no high pressure.

THE PROBLEM

Roofs are the one surface you never want to blast with high pressure — it tears up the shingles. I use a careful brush and a moss-killing powder treatment instead.

WHAT’S INCLUDED

How I take moss off a roof without wrecking it

Roofs are where the wrong method costs you most. Here is exactly what I do.

Brush and powder, never pressure

High pressure strips shingle granules and takes years off a roof. I use a soft brush and moss-killing powder.

The moss keeps dying after I leave

The powder keeps working after I leave, through the next wet season.

Gutters cleared as I go

Everything brushed off the roof gets cleared out of the gutters, not left packed in.

Careful access

I work from the edge and ladder where I can, rather than walking a wet, mossy roof.

Landscaping covered

Anything under the drip line gets covered or rinsed so nothing sits on your plants.

Clean, not stripped

A roof that looks its age without the moss and streaking — not scoured back to bare shingle.

ROOF CLEANING QUESTIONS

Roof cleaning questions I get asked

Will pressure washing ruin my roof?

+

On asphalt shingles, yes — it blasts off the granules that protect the shingle. That is why I never pressure wash roofs.

How do you actually remove roof moss?

+

A soft brush lifts the bulk off, then a moss-killing powder treatment kills what is left in the seams and keeps working for months.

How often does a roof need doing around here?

+

Every two to four years here. North-facing slopes and anything under overhanging trees go first.

Will the moss come back?

+

Slowly. The powder treatment is what buys the time — without it you are only removing what you can see and leaving the roots.

Do you clean the gutters at the same time?

+

I clear what comes off the roof out of your gutters as part of the job. A full gutter clean is separate, and cheaper booked together.

Can you do a metal roof?

+

Yes, but differently — metal gets a soft wash. Brush and powder is for asphalt shingle only.

How much does roof moss removal cost?

+

Comes down to roof size, pitch, how much moss there is and access. Quotes are free, and I will tell you if it can wait a season.
