Methods and systems for analyzing an integrity of a roof covering are presented. An airflow may be directed over one or more shingles or other discontinuous roof covering materials by an airflow unit. A respective lift for each of the discontinuous roof covering materials may then be observed by an imaging unit, and an overall roof integrity rating may then be generated by the one or more processors based on the respective lift of the discontinuous roof covering materials.

A roofing system and method, which includes elongate rain diverting devices for directing rainwater and snowmelt away from an underlying sheet material and roof deck, is provided. The system includes roofing tiles having strips of hook and loop fasteners (H&L strips) adhered to both faces. The rain diverting devices have an H&L strip adhered along a lower edge of both faces. As each new row of tiles is installed on the roof deck, the device is applied over an upper portion of the tiles, extending over and onto the sheet material above the tiles, and across the roof deck. As additional rows of tiles are installed, each device is releasably attached to underlying and overlying tiles by way of the H&L strips adhered to both the tiles and the device. The devices also allow for single lap tiling (less weight on roof deck) and for use of shorter tiles (saving material cost).

A system includes a plurality of photovoltaic modules, each having a mat with an edge and a spacer with an edge, the edge of the mat being attached to the edge of the spacer. The spacer includes a plurality of support members and a solar module mounted to the support members. Each of the support members includes a ledge. The solar module and the ledge form a space therebetween. The space is sized and shaped to receive an edge of a solar module of another of the photovoltaic modules. The spacer of one of the photovoltaic modules overlays the mat of another of the photovoltaic modules.

Methods and systems for analyzing an integrity of a roof covering are presented. One or more roof sections of a structure may be identified with one or more processors. An airflow may then be directed over one or more shingles or other discontinuous roof covering materials of the roof section by an airflow unit. A respective lift for each of the shingles may then be observed by an imaging unit. An adhesion score may then be determined for each of the one or more shingles using the one or more processors. This adhesion score may be based on the respective lift. An overall roof integrity rating may then be generated by the one or more processors, based on the one or more adhesion scores. The overall roof integrity rating may then be provided by the one or more processors to a user of a computing device.

A system includes a photovoltaic module having photovoltaic cells, each having a width, and a roofing shingle having an exposure zone and a headlap zone. A plurality of slots extends from the exposure zone to the headlap zone and define tooth portions. A first one of the tooth portions has a first side defined by a first slot and a second side defined by a second slot adjacent to the first slot. The first tooth portion has a first width that is the photovoltaic cell width multiplied by a first positive integer. A second tooth portion has a first side defined by a third slot and a second side defined by a fourth slot adjacent to the third slot. The second tooth portion has a second width that is the photovoltaic cell width multiplied by a second positive integer different than the first positive integer.
