Roof Soft Washing · Richmond, BC
Roof Soft Washing in Richmond: how it works
Soft washing cleans a roof with low pressure water and a cleaning solution, rather than a hard blast. It is often chosen for moss, algae and dark streaks because it is gentler on shingles. Not every roof suits it, and the solution must be managed carefully. Independent providers do the work and set their own prices. We pass enquiries to them.
When to act
When roof soft washing is worth a call.
- Dark streaks or stains running down the roof
- Moss and algae spread across several slopes
- Roof looks dirty but the shingles are still sound
- You want a cleaner look without scraping everything by hand
- A past cleaning used high pressure and you want a gentler way
What to expect
What good roof soft washing looks like.
Soft washing generally means low pressure rinsing combined with a cleaning solution that kills moss and algae. Lower pressure reduces the risk of stripping granules.
The solution matters. The BC government's roof moss factsheet says products must be approved for roofs in Canada and carry a registration number, and that bleach and soap can harm aquatic life if they reach storm drains.
Heavy moss often still needs to be brushed or scraped first. Soft washing alone may leave thick growth in place until it dies and loosens.
Ask the provider about plant protection, rinsing, and how runoff is kept out of drains. Richmond's Pollution Prevention and Clean-up Bylaw No. 8475 generally prohibits polluting substances entering storm drains.

FAQ
Roof Soft Washing questions.
Is soft washing safer than pressure washing for roofs?
Generally yes. Low pressure is less likely to strip granules or push water under shingles. The roof's age and condition still matter, so ask the provider to assess yours.
Will soft washing affect my roof warranty or insurance?
It can depend on the roof maker's terms. Check your roofing warranty and ask your insurer if you are unsure. Ask the provider what method they will use and keep the quote.
Does soft washing remove all the moss at once?
Not always. Thick moss may need brushing first, and treated moss can take weeks to die and loosen. Ask the provider what result to expect.
