Sikalastic RoofPro Systems

Reinforced Liquid-Applied Roofing and Waterproofing Solutions

Sika USASikalastic RoofPro systems with MTC (Moisture-Triggered Chemistry) incorporate a unique technology that allows the material to use atmospheric moisture to trigger the curing process. This means the waterproofing membranes are capable of curing in a wide range of conditions including extreme temperature ranges and humidity variations. Moisture-triggered chemistry provides Sikalastic RoofPro systems with increased tolerance to substrate and incidental moisture at time of application. Sikalastic RoofPro systems are waterproof shortly after application, providing protection against sudden rainstorms and adverse weather conditions. Due to its unique moisture-triggered chemistry, Sikalastic RoofPro systems offer installation advantages that other liquid-applied systems cannot match:

  • Unlike typical polyurethane systems, Sikalastic RoofPro systems do not release CO2 during the curing process, which can cause outgassing and bubbling.
  • Unlike typical polymethyl methacrylate and other multi- component systems, Sikalastic RoofPro systems are more applicator-friendly in temperature extremes, particularly hot weather.
  • Unlike typical hot-applied rubberized systems, Sikalastic RoofPro systems do not require a separate UV-resistant protection layer, and do not utilize separate sheet rubber flashing materials.


Sikalastic RoofPro membranes are single-component resins, which eliminates the labor costs, inconvenience and potential error involved in mixing multiple components. Single-component technology eliminates incomplete curing and variations in membrane performance that can occur if proper mixing ratios of multiple components are not maintained. In addition, working time is greatly extended, minimizing material waste due to cured, but not applied, material.
