What ARMA Recommends
The Asphalt Roofing Manufacturers Association recommends a 50/50 mix of water and household bleach (sodium hypochlorite) applied at low pressure. Professional roof cleaners in Hialeah use concentrated SH with surfactants for more effective, longer-lasting results.
Professional-Grade Products
- 12.5% Sodium Hypochlorite: The industry standard, diluted to 1–3% for application. Kills Gloeocapsa magma algae on contact
- Cling-On surfactant: Helps cleaning solution adhere to shingle surfaces instead of running off
- Roof Wash soft wash blend: Pre-mixed professional solutions that include algaecide, surfactant, and rust inhibitor
DIY-Friendly Products
- Wet & Forget: No-rinse solution applied once and left to work over weeks. Safe but slow
- Spray & Forget: Similar to Wet & Forget with slightly stronger formula
- 30 SECONDS Outdoor Cleaner: Fast-acting for light staining, safe for shingles when diluted properly
Products to NEVER Use on Shingles
- TSP (trisodium phosphate): Can strip granules and is restricted in Miami-Dade County waterways
- Muriatic acid: Destroys shingles and kills landscaping
- Undiluted bleach: Too concentrated — damages shingles and kills plants
