Permanent Waterproof Roof Coating & Repair


The SANI-TRED® roof coating system offers numerous advantages. It can be applied in cold weather and exposed to rain or snow immediately after application. Once applied, the finished roof should last the life of the building without repairs, backed by a lifetime warranty. Additionally, our system eliminates the costs of removing the old flat roofing system, making it a cost-effective solution.

With SANI-TRED®, small areas of the flat roof can be repaired at a time, thanks to the "molecular welding" of the new-to-old roof materials. This allows for pay-as-you-go repairs with no schedule complications or disturbance to the occupants and contents of the building. Furthermore, waterproofing as you go prevents water damage to new roofing materials or the existing building during construction.

Our new flat roof surface can transform what was once useless space into a walk-on roof deck. SANI-TRED® coatings are designed to withstand heavy commercial foot traffic with no damage, and their uniform color makes it easy to identify and repair any damage that may occur. Our systems are completely waterproof, making standing water no problem, and their light color reflects sunlight, reducing heat absorption.

Unlike tar, which is weak and expands and shrinks with temperature changes, SANI-TRED®'s LRB/TAV mixture cures to a strong, solid, waterproof, adhesive rubber that does not change shape with temperature extremes. Additionally, any custom fitting requirements, scupper designs, or modifications are quick and easy with our products.

Our SANI-TRED® waterproof roof sealant products are truly unique and not just another acrylic latex. We offer roof/deck materials that are tough enough for heavy foot or vehicle traffic, and our systems can be applied to pitched, galvanized, painted steel roofs, nail head sealing, corrosion protection, and repair. With our flat commercial roofing systems, you get monolithic (one-piece) sealing, regardless of the multitude of mechanical through deck vents or fittings.

Permaflex, LRB (Liquid Rubber Base) and TAV (Thickening Activator)



Permaflex is the top coat that seals metal, plywood, concrete and other types of roofing surfaces. It’s also functions as a first priming coat when using LRB (Liquid Rubber Base) and TAV (Thickening Activator). The priming coat fills holes & voids in the substrate.


These two waterproof roof sealer products work together to patch and profile any joints, seams, cracks, holes or rough areas. Products are packaged separately because different mixes are required for different applications. We provide all the tools you need to take on any roofing project.
