Sansin Roof-Tec

Protective Treatment for Cedar and Pine Shake & Shingle Roofs

Sansin Roof-Tec is a penetrating water-borne treatment designed to dramatically extend the life of cedar and pine shake or shingle roofs. It hydrates wood with deep-penetrating resins that reduce warping, shrinking, and checking while providing superior UV and water resistance. Available in Naturals, Translucent, Saturated, Ultra Saturated, and Solid Hide color options, Roof-Tec enhances the character of wood while protecting it from the harshest elements.

Roof-Tec is specially formulated for wood roof applications, offering a breathable, eco-friendly finish that is both highly water-repellent and UV-resistant. Its monolithic bonding system creates a molecular-level connection with wood fibers, reducing structural degradation and surface erosion.
