Devices, systems and methods for providing a retrofit and repair technique and device for asphalt shingle roof coverings or roofing systems that exhibit premature adhesive tab seal failures. A device can have a handle at one end and a blade tip end at the other end has the blade tip inserted under a shingle to be repaired. The device can dispense a row of dabs at a selected location under roof shingle(s). The dispenser can dispense a row of individual dabs by a volume container. Alternatively, the dispenser can have a roll with a plurality of rows of pre-made dabs of adhesive on removable type paper. Once the blade tip end of the tool device is inserted between upper and lower shingles, the dabs are dispensed by removing the release paper, and the device is pulled out with the release tape is wound up, advancing the adhesive cylinders. Next, the worker can press down on the upper shingle. Additional embodiments can include adhesive adapters having dispensing heads that attach to ends of caulking tubes on caulking guns, or to caulking gun cartridges, and the like.

Devices configured to operate on an angled surface (e.g., a roof), and associated systems and methods are disclosed herein. In some embodiments, representative systems include an apparatus with a body assembly, an arm assembly coupled to the body assembly, and a material handling assembly coupled to the arm assembly. The body assembly can include a body frame, and a plurality of positioning assemblies coupleable to cables and configured to position and/or orient the body frame on the surface. The arm assembly includes a proximal end portion rotatably coupled to the body portion and a distal end portion opposite the proximal end portion. The material handling assembly is coupled to the distal end portion of the arm assembly and is configured to carry a surface material to be positioned on the angled surface.

This invention provides fall protection systems comprising a suspension fabric, supported by a grid-work of longitudinal and lateral bands, in metal building construction. The fall protection system uses safety clips to attach lateral bands to intermediate purlins, and also provides novel attachments of the lateral bands to eaves and ridges whereby the respective eave and/or the ridge absorbs an enhanced portion of the force of impact when an object falls onto the fall protection system. The invention further provides methods of installing such systems, and buildings embodying such systems.

The invention provides for a roofing membrane tensioner 10 having a base 102 with a hook 36 for catching the edge 22 of an underlying surface 20, a membrane connector 108, and a means for moving the membrane connector towards the edge by applying force inwardly 24 from the edge. The means for moving the membrane connector towards the edge can be a lever 104 operated substantially in the same plane as the underlying surface. The force can be applied at least 50 cm from the edge. The base can have a flat side and a hook side. The base can also have a mount 110 for connecting the lever. The mount can be the fulcrum 110 for the lever. The invention also provides for a method for tensioning a roof membrane 40 towards an edge 22 of a roof surface 20 by securing a preceding tab 41 of the roof membrane to the roof surface, hooking a slidable base 102 having a fulcrum 110 for an attached lever 104 to the edge, connecting a membrane connector 108 between a subsequent tab of the roof membrane and the lever on one side of the fulcrum, and tensioning the roof membrane by applying inwardly 24 directed effort to the lever on the other side of the fulcrum. The invention also provides for a roof membrane tensioning system 10 having a mounting means for positioning and adjusting a base 102 on a roof 20, a membrane connector 108, and a membrane tensioning mechanism for tightening the membrane towards an edge of a roof by applying force inwardly 24 from the edge 22.

Systems/techniques are provided for facilitating vertical seam sealing devices for metal roofs. In various embodiments, a device can comprise a frame having a handle. In various aspects, the device can comprise one or more carriage guides extending downward from the frame and configured to mate with a vertical seam of a metal roof. In various instances, pushing or pulling on the handle while the one or more carriage guides are mated with the vertical seam can cause the frame to ride along the vertical seam. In various cases, the device can comprise a set of rollers coupled to the frame and configured to dispense sealing material onto the vertical seam as the frame rides along the vertical seam.
