Designed on a site-specific basis, ColorGard controls snow migration while maintaining the clean colorful appearance of the roof with perfect color and finish matching. ColorGard is the only snow retention system that can be guaranteed for total system performance and exact color match for the life of the roof! Punched ColorGard is slotted every 4.00" on center for seams that are spaced accordingly, i.e. divisible by 4.00".
