Your guide to using RoofTec chemicals for specific exterior cleaning applications.
Critical Steps to Prevent Risks and Ensure Satisfied Customers
- Before cleaning, test each product on a hidden area of the surface to be cleaned.
- Inspect all areas to be cleaned, taking note of any stained wood (doors or decks), cameras, electrical outlets, solar panels, lights, and fans. Protect as necessary. Also, be careful to prevent runoff into koi fish ponds. Communicate with customers about any existing damage, oxidation, old paint, or pre-existing dead plants before starting the job.
- Apply pre-cleaning fresh water rinse to any plants that may get overspray or run off and that may be damaged by cleaning solutions. Saturate gutter runoff ground areas with fresh water.
- Always use the appropriate personal protection equipment, including a respirator, goggles, and protective clothing.
- Completely cover the roof with a cleaning solution from the gutter line to the peak of the roof and walls from the ground to the gutter line. After 10 minutes, apply more solution to any areas of heavy organic growth still visible.
- After cleaning, use fresh water to rinse any plants that may have come in contact with the cleaning solution.
