The number one litigated construction trade in the nation is roofing and waterproofing. Now with the emergence of vegetated roofing as a more commonplace commercial application, the potential liabilities have been exacerbated through the installation of overburden on roofing/waterproofing materials. The use of water tests and thermal imaging on these covered and constantly moist conditions are no longer effective methods in determining the location of a roof leak or breach.rnrn Leak Detection is the answer to minimizing your exposure to potential building damage, reduced employee productivity and provides the peace of mind that if you have a leak that it will be resolved in a quick and efficient manner. We offer both reactive and proactive systems that will pin point any leak as close as to 2” from the source. We recommend leak detection solutions to all of our blue and vegetative roofing clients. Additionally, it is a standard requirement to receive any Hanging Gardens blue or vegetative roofing warranty. We too understand the necessity to limit our own liabilities.Request Specifications

Previously utilized to promote evaporative cooling prior to the age of air conditioning, Blue roofing is experiencing a renaissance that once again utilizes roofs as open-air cisterns for rainwater collection. These systems offer a tremendous amount of water could that can be stored on a building’s roof, given the right waterproof membrane and structural loading capacity. Water weighs 62.4lbs per cubic foot. Most cities require that the first inch of rainfall be mitigated on site, which translates to 5.2lbs per inch of depth per square foot on a roof’s surface. Our blue roofs designs have an average depth of 2-4 inches. In addition, we ensure that every blue roof design has multiple fail-safes. This is accomplished through our leak detection systems (link to leak detection), raised scuppers which act as overflows once the roof has reached peak capacity, as well as state-of-the-art roof drains which “flush” the entire blue roof through WIFI technology. Our systems provide volume stormwater mitigation through cost effective performance products and design.
