About

Citra-Shield was developed over 18 years ago in Southwest Florida. At the time our cleaning company was pressure washing roofs and exterior surfaces to remove stains caused by biological growth. While pressure washing worked well, we would run into a myriad of issues cause by high pressure cleaning. Not only were we using a lot of water, we found that the exterior algae, mildew and fungus would return after a cleaning & treatment. Upon investigation we learned that these stain causing fungus were actually alive and had taken root in the surface. And while pressure cleaning removed the surface  stains, the water actually promoted more growth. Just like watering your plants. We learned that many companies were using harsh chemicals and phosphates (Bleach/Chlorine) to treat these stains, however these treatment were voiding roofing warranties and many times fading the color of the exterior surface.
