- Zinc strips are "usually considered the long-term solution," according to the University of Washington's Miller Library, which quotes Oregon State University Extension.
- Copper gutters: OSU Extension warns not to use zinc sulfate if your roof has copper gutters, downspouts or flashing, because zinc corrodes copper.
