At least one collar member (11, 12, 13, 14) of the second underroof collar comprises a reduced amount of collar material compared to the corresponding collar member of the first underroof collar.

A packed flashing assembly (1) for use with a group of roof windows comprising at least two roof windows mounted adjacent to each other in a sloped roof structure (3) is disclosed. The flashing assembly comprises a first set (I) of flashing members including one top flashing member (11), one bottom flashing member (12), and two side flashing members (13, 14) contained in a first packaging element (4), and a second set (II) of flashing members including one middle gutter flashing member (15, 19) and two other flashing members (11, 12; 13, 14) contained in a second packaging element. When mounting the flashing assembly at least three flashing members of the first set are mounted at a first roof window, and at least one flashing member of the first set is mounted at a second roof window, and the second set is mounted at the second roof window.

This invention presents a wall mounted receiver to accommodate insulated or non-insulated pipes and at least one inlet or portal for at least one pipe conduit or wiring per portal and with a high degree of flexibility and unique mechanical connection security; this receiver is arranged to receive the piping from any directional angle with a unique flexible inlet capability; without limitation, this receiver is for use with refrigeration or air conditioning equipment and related connections, such as insulated pipes, non-insulated pipes, condensation piping, conduit and wiring. The receiver can be mounted to different wall surface types without the assistance of a wall bracket; can also be fit into tight space service areas depending on refrigeration equipment requirements; can be installed in new construction applications; and can also upgrade existing installations without the need to cut the existing piping.

A sealing member for use between a flashing member and a roofing material is made of a compressible material and with slits and/or weakening sections extending into the sealing member from the exterior surface towards the interior surface, each slit and/or weakening section extending from one side surface to the other side surface. In one embodiment the slits and/or weakening sections extend in parallel planes, each plane being substantially parallel to the height direction and extending at an angle of 15-75 degrees to the length direction of the sealing member, preferably an angle of 45 degrees. In use the sealing member is arranged on a flashing member and a roofing material is arranged to rest on the sealing member and compress one or more sections of the sealing member. If the sealing member includes weakening sections, at least one of these is at least partially broken when the sealing member is compressed.

A flashing assembly comprising a top flashing arrangement, a roof element system comprising such a flashing assembly, and a method of manufacturing a flashing assembly. In the flashing assembly (11), a top flashing arrangement comprises at least one pair of an inner top flashing element (111) and an outer top flashing element (112), and each inner top flashing element (111) and the associated outer top flashing element (112) are configured to be interconnected in a telescopic joint (115).

A lateral intermediate flashing element (100) for connecting lateral longitudinal flashing elements (200; 300) for flashing roof elements positioned adjacent each other at different altitudes along a slanted roof, comprises a longitudinal portion (110) with a generally L-shaped cross-section with a first leg (101) and a second leg (102), said second leg (102) comprising a slit-shaped pocket (105) with an opening towards a distal edge portion, the longitudinal portion (110) having an upper longitudinal end (120) and a lower longitudinal end (121), a width of the longitudinal portion (110) of the second leg (102) being smaller at the lower longitudinal end (121) than such width of the longitudinal portion (110) at the upper longitudinal end (120).

The present subject matter provides apparatus for connecting a roof assembly to a membrane using at least one backer rod connected to the membrane, including: counterflashing disposed about the perimeter of the roof assembly, the counterflashing including a plurality of grips configured to receive and engage the at least one backer rod in contact with the membrane, so as to hold the membrane securely in position and maintain a weather seal at a desired flashing height of the membrane. In various examples, the roof assembly includes a roof hatch, window, or other fenestration unit. In various examples, the present subject matter provides a hatch attached to a wall for sealing an opening. In various examples, the present subject matter provides a method for operating a roof assembly for connection to a roof membrane.

Various roof vent adaptors are disclosed. The roof vent adaptors can be used to seal penetrations on buildings, such as vent penetrations on metal or non-metal roofs. In various embodiments, the roof vent adaptor includes a sealing member, an outer securing unit and an inner securing unit. The roof vent adaptor can be secured to the roof to provide a generally liquid-tight seal around the roof vent, thereby inhibiting or preventing water intrusion into the building.

A connector arrangement for a flashing assembly for use in a roof window arrangement is disclosed. It comprises a base connector element, an elevation element and a top connector element. Both connector elements have a gutter in their exterior side, and the gutter is open at one end so that water can drain out of it. An attachment section on the interior side of the base connector element is configured for being attached to a bracket used for connecting a roof window to a load-bearing structure, and the elevation element supports the top connector element so that it is positioned above the base connector element. In the mounted state the second end of the top connector element is arranged above the gutter of the base connector element and their length directions extend substantially in parallel to each other. A method for weather proofing a roof window arrangement is also disclosed.
