S5 Lifetime Warranty

S-5! offers two main warranties: a Lifetime Product Defect Warranty, covering defects in materials and workmanship, and a System Performance Warranty for the ColorGard® Snow Retention system, which is unique in the snow guard market and has a term of 30 years or the life of the roof, whichever comes first. The Product Defect Warranty has been extended to a lifetime term based on their long history of minimal claims and their products designed to outlast the roofs they are mounted on.
