## Price

$300-$1,200 standard home, treatment. reconciles Seattle-area published averages ($309-$406, range $260-$454) with the broader Western Washington professional-cleaning range ($450-$1,200) — not Tacoma-exclusive data but directly applicable to this region; steep or heavily-mossed roofs run higher.

## What's included

- Hand and soft-brush moss removal — never a pressure washer, which strips the protective granule layer and can drive water under tabs
- Algae/moss treatment application to slow regrowth
- Gutter clearing of moss debris as part of the same visit
- An honest assessment of whether the roof underneath is still sound or already needs replacement
- A recommended treatment interval sized to the specific lot's tree cover and shade
- Special care around original wood-shingle roofs on North Slope and Stadium District homes, where removal method matters even more
- Written price before work starts
- A day-rate option for larger or heavily-mossed roofs, quoted honestly rather than a flat per-square number stretched to fit

## Process

01. **Assess the roof** - We check how far moss has progressed and whether it's purely cosmetic or has already lifted shingles or shakes.
02. **Gentle removal** - Hand and soft-brush removal, never a pressure washer, plus treatment application to slow regrowth.
03. **Gutter clearing** - Moss debris cleared from gutters in the same visit so it doesn't wash back onto the roof.
04. **Interval recommendation** - We recommend a treatment interval based on your specific lot's tree cover and shade, not a blanket citywide schedule.

## When it's needed

- Visible moss growth on north-facing or heavily shaded roof sections
- Shingles or shakes lifting where moss has grown underneath
- Green or black algae streaking on shingle surfaces
- Gutters filling with moss debris
- Heavy tree canopy shading a significant portion of the roof, common in North Slope and Proctor District
- A roof that hasn't been treated in several rainy seasons

## FAQ

**Why not just pressure wash the moss off?**

Pressure washing strips the protective granule layer off shingles and can drive water up under tabs or shakes — it does more long-term harm than the moss itself. Gentle hand and brush removal plus treatment is the standard manufacturers actually recommend.

**Should I treat the moss or just replace the roof?**

If the material underneath is still structurally sound, treatment is usually the better spend. If a large share of the roof already shows deck damage from years of moss, replacement stops you from paying for repeated treatments on a failing roof. See our comparison guide.

**How fast does moss actually damage a roof in Tacoma's climate?**

See our dedicated guide — it depends on shade, roof pitch, and material, but moss trapped against shingle or shake for multiple rainy seasons can meaningfully shorten service life.
