| Method | Best For | Pros | Cons |
|---|---|---|---|
| Softwash | Algae, moss, lichens on asphalt and composite shingles | Low impact, effective for organic growth, less water pressure | Requires cleaning solution; longer dwell time |
| Bleach-Based Solution | Stubborn stains and moss | Powerful whitening and disinfecting effect | Can discolor or damage certain shingles; requires thorough rinsing |
| Vinegar Solution | Light staining, mildew on metal or mineral-based shingles | Safer for some surfaces; environmentally friendlier | Less effective on heavy staining |
| Pressure Washing | Heavy debris on sturdy, non-porous shingles | Fast, powerful cleaning | High risk of shingle damage if misused; not suitable for all roofs |
