🏠 How Does Roof Soft Washing Work?
A lot of homeowners don’t realize that properly cleaning a roof doesn’t involve high-pressure washing!
These photos show the process of soft washing a roof covered in moss and algae.
We apply a specialized cleaning solution using very low pressure, allowing it to soak into the moss, algae, and other organic growth. The solution kills the growth without the need for damaging high pressure.
The important part? We let the solution do the work!
As you can see in the second photo, the moss has already started changing color after treatment. We don’t need to scrape or blast it off. Once treated, the dead moss will gradually loosen and wash away naturally with rain and weather over time.
We also typically return within a couple of weeks to check on the roof and see how the treatment is progressing. This allows us to make sure everything is working as expected and determine if any areas need additional attention.
Roof soft washing is a process, not always an instant transformation. Our priority is getting the job done properly while protecting your shingles!
