When softwashing a roof, should you scrape moss from the roof, or not? This is a question we are frequently asked. And there are varying points of view about the best way to softwash moss on a roof.
So we thought to clarify the situation in light of our experience.
Ben, who always goes to great lengths to explore all the possible options when softwashing a roof, has found this from his experience:
Remove large moss balls from the roof prior to softwashing, by using a Benz Professional Roof Moss Scraper. It’s best to remove all moss from low pitched roofs situated in sheltered or shady locations. Steep pitched roofs are more forgiving of less thorough scraping.
In general, spray-only treatment – with any softwash chemical – of roof moss is never completely satisfactory. Pre-scraping prior to treating with Benz Bio Cleanze has proved to be the most effective approach.
Ben also experimented with spraying moss with highly concentrated Lightning Cleanze.
This approach quickly turned the moss into a mush that somehow he had to remove.
The problem was that rain washed the mush into gutters, downpipes and drains. And therefore could potentially cause serious, hard to remove blockages.
Removing the mush by hand, prior to it entering the drainage system, turned out to be messy, difficult and highly unpleasant.
If you try this approach, remember that there could be some active sodium hypochlorite remaining in the mush, so stringent H&S precautions, including appropriate PPE, should be seriously considered and implemented.

When soft washing it's vitally important to protect surrounding building materials. e.g. lead flashing. And not to create "clean streaks" – from overspray and run-off – on surfaces that are not part of your contract.

It's a free resource for people wanting to learn about the soft washing industry, to expand an existing business, or build a new business.
Soft washing reduces, or even eliminates, the need to use high-pressure washing.
Instead, once the build up of algae, lichen, fungus, moss and mould – the root causes of properties looking "dirty" – has been treated, the natural "self-cleansing" of sun, rain and wind removes the surface residue through time.
By educating the cleaning trade and public about soft washing we are helping develop an industry that offers sustainable treatments to clean and maintain exterior hard surfaces.
