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! Unpunched ColorGard is the most versatile and easy to install when used with the S-5 VersaClip. The unpunched configuration works well with VersaBracket, and is the right choice when the roof is laid out with untrue seam width or when the seam width is not divisible by 4. If in any doubt, use unpunched.?
