Roof Tiles/Slates
Our roof tiles and slates cleaning products include effective roof cleaning biocides. They clean and treat clay, concrete tiles, and slate surfaces. Our formulations remove dirt, algae, lichen, and environmental contaminants. These stain removers restore the appearance of your clients’ roofs without causing damage.
Clay tiles are less porous than concrete. As a result, residual protection may not last as long on clay surfaces. Environmental factors, such as weather exposure and surrounding foliage, can also affect treatment longevity.
For optimal results, when using PureSeal cleaning products, remove moss completely before applying any treatment. HSE regulations classify moss as a plant. Removing moss allows treatments to penetrate the roof surface effectively. This maximises their protective benefits.
PureSeal’s roof tiles and slates cleaning products include HSE licensed biocides. They provide professionals a safe and powerful way to clean roofs. Always follow product guidelines closely and use proper PPE for safety. Consider options that allow you to apply and leave for ease of use.
