Our system for metal roofs completely seals and waterproofs seams, vents, and fastening devices. The fluid applied, 100% acrylic waterproofing membrane forms a thoroughly watertight, flexible and monolithic barrier against any water penetration. Polyester embedded with fluid applied waterproofing materials provides lasting protection, summer and winter. This seam sealing technique prevents water from entering seams and joints and prevents wintertime expansion of these areas due to freezing water.
