Roof Cleaning BC
Done Right. Built to Last.
BC's wet climate is the #1 enemy of asphalt shingles. Moss, algae, and debris trap moisture and accelerate aging. Our soft-wash roof cleaning combined with GoNano nanotechnology doesn't just clean your roof — it restores and protects it for up to 15 years.
The BC Problem
Why BC roofs get dirty faster than anywhere else
The Lower Mainland averages 1,150mm of rain per year. That constant moisture, combined with tree cover and mild temperatures, creates the perfect environment for moss, algae, lichen, and black streaks to colonize your roof — often within 2–3 years of installation.
- Moss roots lift shingles and allow water infiltration
- Algae causes black streaking and accelerates UV degradation
- Lichen is the hardest to remove and causes permanent staining
- Debris buildup traps moisture and causes premature granule loss
- Untreated roofs in BC can fail 5–10 years early

Roof Cleaning BC — FAQ
How much does roof cleaning cost in BC?
Roof cleaning in BC typically ranges from $300–$800 depending on roof size and condition. NanoShieldBC offers free inspections so you get an accurate quote before any work begins.
How often should I clean my roof in BC?
In BC's wet climate, most roofs benefit from cleaning every 2–3 years. Homes under heavy tree cover may need annual attention to prevent moss and algae buildup.
Is soft wash or pressure washing better for roofs?
Soft wash is always recommended for asphalt shingles. High-pressure washing strips granules and voids manufacturer warranties. We use low-pressure soft wash combined with GoNano treatment for lasting results.

Yes — removing moss, algae, and debris prevents moisture retention and biological damage. Combined with GoNano nanotechnology treatment, you can add up to 15 years to your roof's lifespan.
