You can, but you should not. High pressure strips the granules off shingles, forces water under them and can void your roof warranty.
What pros do instead: soft wash
Soft washing uses low pressure plus a cleaning mix that kills the algae, mold and mildew causing those black streaks. It is gentler and the results last longer.
Signs your roof needs cleaning
- Black streaks (algae)
- Green moss patches
- Dark, dirty spots on the north side
