About Us


ERSystems® specializes in roof coating restoration systems that extend the life of your existing roof while reducing energy use related to cooling your building.

ERSystems® (Elastomeric Roof Coatings), a brand of Holcim, is an international leader in cool roof coating technology and a strong supporter of sustainable and renewable building technologies. ERSystems’ highly reflective roof coatings are Energy Star certified, meet LEED requirements, and have been used to restore millions of square feet of metal, BUR, single-ply membrane, and foam roofing systems.

ERSystems® white reflective roof coatings can more than double the roof life expectancy at a fraction of the cost of re-roofing. Roof restoration is the process of changing an aged roof into a new or even better than new condition. Every roof system has weaknesses/limitations that may lead to roof failure. However, roof restoration addresses those issues by reinforcing the original weaknesses and limitations of the roof, repairing material inadequacies and failures resulting in leaks, and using a coating to protect the roof for longer performance life. When a roof is transformed into a new or better than new condition, it protects the roof surface from the natural degradation caused by the weather, which extends the life of the roof. Roof Restoration also limits the amount of roof waste being placed in our landfill.

ERSystems® offers a complete line of the supreme quality elastomeric roof coatings and systems – highly reflective coatings, sealants, and adhesives — each having the capability to stretch, bend, and twist as the building moves. ERSystems® was the first to develop roof restoration systems specifically designed for its particular application: Metal roofing and walls, Singly Ply Membranes, Asphalt roofing, Spray Polyurethane Foam, and masonry walls. Top sellers include H.E.R, SW, 300, 1000 Plus, and Polyurethane 300 System.
