Some embodiments of the present technology may encompass roofing membranes. The roofing membranes may include a waterproof membrane having a top major surface. The roofing membranes may include a first liner having a top surface and a bottom surface. The bottom surface of the first liner may be removably coupled with the top major surface of the waterproof membrane. The first liner may have a first color. The roofing membranes may include a second liner having a top surface and a bottom surface. A bottom surface of the second liner may be coupled with the top surface of the first liner. The second liner may have a second color that is different than the first color.

The system of the present invention is used for detecting and locating leaks in a roofing envelope that includes an insulation package. The system includes at least two contacts disposed within the roofing envelope, where at least one contact is active and at least one is passive. The active contact is capable of emitting an electric signal of a known voltage, and the passive contact is capable of reading voltage at the location of the passive contact. All contacts are in electrical communication with a computer.

A system, method and apparatus for detecting moisture leaks in roofs and for providing a visual alert regarding such leaks, and which does not require puncturing or compromise of the roof membrane, comprises a dual part moisture detection and indicator system which comprises a wicking sensor, a wicking portion, a non-electronic trigger portion below the membrane, which is enabled to receive a non-electronic signal from the wicking portion and a non-electronic indicator portion above the membrane which is enabled to receive a non-electronic signal from the trigger portion and to thereafter produce a notification of a leak.

A system and method for managing maintenance and repair of a commercial building roof that creates an access event log each time a roof location is accessed and precipitation event log is created each time precipitation occurs at the roof location to narrow the search for access events possibly resulting in roof damage causing a roof leak. A centralized computing system accessible by remote computing devices at each rooftop location is accessed to create an access event log when personnel access the roof. The computing system collects weather data for each rooftop location based on the global position coordinates for the rooftop location. Upon discovery of a roof leak, a system query will identify access events occurring since the latest precipitation event after which no leaks were reported to identify a list of potential causes for the roof damage. The system and method may also be used to consolidate roof maintenance, inspection, and repair to improve asset management.

An apparatus, system and method for detecting defects in building structures is provided. The apparatus includes a detector operable to determine an indication of the defect; and a transmitter operable to wirelessly transmit the indication from the apparatus to a central controller. The system includes the detection unit; a locator operable to determine the location of the detection unit; and a memory for storing the indication and the location in association with each other. The memory may be part of a central controller in wireless communication with the detection unit. The apparatus or central controller may include a processor operable to determine from a plurality of measurements performed by the detection unit a resultant measurement vector indicating a direction from the detection unit toward the defect. The detection unit may be operable to autonomously change its location. A display showing resultant measurement vectors at various locations can be produced.

Gypsum panels, methods for their manufacture, and systems and methods for monitoring environmental conditions with such panels are provided herein. The panels include a gypsum core having a first surface and an opposed second surface, a first facer material associated with the first surface of the gypsum core, and an environmental sensor assembly associated with the gypsum panel and configured to detect an environmental condition of the gypsum panel and wirelessly communicate data on the environmental condition to a reader.

An intelligent roof drain system includes a roof drain surrounded by a drain plate. A water seepage detection module is disposed proximate the drain plate. The water seepage detection module includes water seepage detection sensors and circuitry and an antenna system to inductively receive power and communicate water seepage data. A roofing membrane is disposed over the water seepage detection module. A monitoring module that includes control circuitry, power supply circuitry, water level detection circuitry, communications interface circuitry, and an antenna system to inductively supply power to and communicate with the water seepage detection module is disposed proximate the water seepage detection module such that the antenna systems align. The intelligent roof drain system can detect water seepage under the roofing membrane and standing water proximate the roof drain and communicate such events to a gateway and/or building management system.
