Our IKO StormShield® Ice & Water Protector is a modified bitumen roll roofing product with a self-adhesive backing protected by a silicone-treated release sheet, which is easily removed during installation. StormShield consists of a resilient, non-woven glass fiber mat, which is permeated and coated with SBS modified bitumen and mineral surface. It is used for waterproofing under shingled roofs preventing water penetration due to ice dams or wind-driven rain. It can also be used as a flashing membrane around dormers, vent stacks, skylights and other roof-top structures or apertures, or around doors and windows.
