Roof refurbishment is increasingly more important in today’s construction world as a sustainable way of extending an existing roof’s lifespan. Buildings are typically built with a design that is intended to have a 50-year life. The roofs on the buildings will most likely need maintenance or refurbishment at certain stages throughout this lifetime to ensure continuous protection against water ingress and other climate-related exposures. One of the biggest advantages of liquid applied membranes is that the existing roof does not need to be torn off to be revived. 

Sika liquid applied membranes, Sikalastic RoofPro or Sikalastic RoofCoat, are applied directly over the existing roof surface. An inspection to ensure the substrate’s integrity, a proper cleaning and appropriate primer and the roof can be given a new life with a warranty. The choice is yours to either use the RoofPro system fully reinforced, or ProTect or RoofCoat systems locally reinforced as needed.
