How We Do It
Roof Cleaning done the right way
Moss holds moisture against your roof and can lift shingles over time. Dark streaks are usually algae feeding on the roofing material. Both are common across South King County's tree-covered neighborhoods.
We use low-pressure methods designed for roofs — never high pressure on shingles — so your roof gets clean without unnecessary wear.
Common Questions
Roof Cleaning questions
Do you pressure wash roofs?
No. High pressure can damage shingles, so we clean roofs with low-pressure methods.
How often should a roof be cleaned?
It depends on shade and tree cover. Many Western Washington roofs benefit from a cleaning every one to three years.
