How to Hire the Right Professional
When hiring a roof cleaning company, you can verify their standards by looking for specific credentials:
HSE Registration:
Ensure the biocide they use (such as PureSeal BioClear Pro or Bac50) has an HSE approval number.
Proper Training:
Professional cleaners should hold a Certificate of Competence (e.g., PA1 and PA6 certifications) for safely applying professional pesticides and biocides.
