A roof mount assembly mounts a structure to a roof haying a rafter and a substrate supported by the rafter. The roof mount assembly includes a piece of flashing positioned on the substrate. The flashing includes a first surface, a second surface opposite the first surface and an aperture extending through the flashing. A fastener extends through the flashing aperture. A bracket is connected to the flashing via the fastener, and the bracket is sized to support at least one roof mounted structure on the roof. A seal is positioned between the flashing aperture and the fastener. The seal is sized to form a water-tight seal with the aperture to inhibit flow of fluid through the aperture. The seal includes a first portion and a second portion, in which the first portion is positioned to abut the flashing first surface and the second portion is positioned to extend through the aperture.

An anchor platform assembly for anchoring an object to a raised, generally flat roof-like structure, has an anchor baseplate having a top surface and a bottom surface, and an internally threaded blindbore extending at least partially from the top surface generally towards the bottom surface and fasteners for fastening an object to the anchor baseplate via its blindbore, and for fastening the anchor baseplate to a top surface of a roof-like structure. The assembly is especially intended for supporting, e.g., glass railings on balconies, terraces and flat roofs and for mounted solar panels on both flat and pitched roofs which provides strength and affords watertight performance.

A roof vent system includes an attic flange member for installing adjacent a roof sheathing inside an attic, a roof skirt coupled to the attic flange and installed on an exterior of a roof, and a roof transition duct having an exterior opening that permits the ingress and egress of air through the roof vent system. The roof transition duct is coupled to the roof skirt and defines an upper end of the roof vent system. A grill is positioned over the exterior opening.

The sealing device for construction comprises a duct and a linking member mounted around and rigidly connected to the duct, wherein the duct comprises: an axial main portion around which the linking member is mounted, a radial bead formed on the main portion and extending radially outwards, and a distal end portion extending the main portion radially outwards and which is axially facing the bead to form therebetween an outwardly radially open annular mounting slot, the distal end portion extending radially beyond the bead, the main portion, the distal end portion and the bead of the duct being made of one piece, the linking member being mounted in the mounting slot and gripped axially between the bead and the distal end portion of the duct.

Disclosed herein is a roof mount installation assembly. The roof mount installation assembly includes a roof mount, a flashing patch, and an adapter cap. The roof mount has a base and a threaded post. The flashing patch has an opening. The flashing patch is configured to surround the base. The opening is configured to allow the threaded post to extend therethrough. The adapter cap is configured to be removably mounted over the flashing patch. The adapter cap is configured to apply a force to the flashing patch for sealing the flashing patch around the roof mount.

A roof curb supported by an upstanding support curb to support various objects including, but not limited to, screens, architectural screens, catwalks, lighting, speakers, security apparatus, cameras, weather indicators, electronic devices, antennae, sound dampening materials, advertising, and security cages. The roof curb includes a top curb portion and two or more spaced, generally horizontal extending support members which then, in turn, support one or more objects such that no portion of the object(s) comes into contact with the underlying roof.

The present disclosure provides sealing devices and construction methods thereof. The sealing devices include a duct having a main axial portion, an intermediate annular portion facing the main axial portion, and an annular end portion facing the intermediate annular portion. The intermediate annular portion and the end annular portion are connected by an annular fold so as to form an axial annular mounting slot that is axially open opposite this annular fold. A connecting member comprises a radial plateau and, around a through-opening, an axial annular mounting portion. The axial annular mounting portion of the connection member is engaged and grasped in the axial mounting slot between the intermediate annular portion and the end annular portion of the duct.

A building including a roof and a rooftop mechanical unit, the rooftop mechanical unit being supported on top of the roof by at least a first roof curb and a second roof curb, a gap being provided between the roof curbs, each of the roof curbs being less than 15 feet in length; wind can blow snow through the gap and out the other side, which inhibits the buildup of a snowdrift which undesirably increases roof load.
