The UnderShield product is designed as a water diversion system under normal weather and rain conditions; however it is not a waterproof roof system. Proper cleaning and flushing of debris by the property owner is important to allow the rain water to flow unobstructed to the exit point and to not create excess weight buildup on the surface of UnderShield. The System can temporarily experience minor drips. Occasional droplets on the underside also could result from normal condensation. Having a qualified professional install and follow the installation instructions carefully is necessary for best performance.
