·CL ROCK's roofing granules is manufactured through a high-temperature inorganic process. All the pigments, binder and additive used are inorganic materials to form ceramic coating which ensure that the product is durable, stain-resistant, and chemically stable.
·Choosing opaque and high hardness as raw stone, protecting the asphalt base from sunlight.
·The surface treatment design makes the granule combine more closely with the asphalt base. Excellent hydrophobic properties will protect asphalt base from rainwater intrusion.
·Color consistency from lot to lot is tracked throughout the entire process of production and delivery: formula-production-delivery.

·CL ROCK's copper roofing granules can effectively destroy the algae growing environment. They are specially designed in wet humid environmentns to solve the algae moss problem on the asphalt shingle.
·Copper roofing granules guarantees anti-algae performance for more than 10 years.
·Adding 4-10% of copper roofing granules to asphalt shingle based on wet level can achieve anti-algae effect.
·Copper granule can be designed to different color to match different shingle patterns.
·They have all the characteristics of ordinary roofing granules.
