Before hiring someone for roof moss treatment, ask these three questions:
❓ Licensed by the Oregon Department of Agriculture for roof moss control?
❓ Insured to perform roof work?
❓ Using roof-safe treatment methods?
Why ask?
Many homeowners don't realize that roof moss treatment is regulated in Oregon. Licensing helps ensure the applicator has met Oregon's requirements and understands how to safely perform roof moss treatment.
At Suds Doctor:
✅ Oregon Department of Agriculture licensed for roof moss control
✅ Fully insured for roof work
✅ Professional roof-safe treatment methods
✅ No high-pressure roof washing for moss control
Every roof is different.
Not every roof with moss needs the same solution. The right approach depends on how much moss is present and the condition of the roof. That's why we start with an honest assessment instead of recommending the same service for every roof.
We believe homeowners should have the information they need to make an informed decision, no matter who they hire.
