Vents are disclosed for covering openings on roofs. The disclosed vents cover openings on metal roofs and prevent moisture and objects from entering the opening while allowing air to pass therethrough. The vents disclosed herein also prevent moisture from entering the building through openings that can be created when the vents are attached to a roof. The vents include a cap, a collar, and a flashing configured to contact the roof. The vents can also include a screen placed between the cap and the collar. The collar can have arms formed on an upper portion thereof to facilitate connection of the collar to the cap. Feet can be formed on a bottom portion of the collar. Once the vent is fully assembled, the feet can be positioned underneath the flashing and can be the main connection point of the vent to a roof. Due to the design of this assembly, fasteners pass through the feet providing a sound and secure attachment to the roof. The feet are then covered from moisture, rain, and/or snow by a flashing, and the flashing is then secured by screws or other fasteners passing through the reinforcement material and through the flashing itself which provides a weatherproof seal.

A flashing piece, having an outer portion, defining an opening and made of a first polymeric material and an inner portion, joined to the outer portion about the opening and extending across and covering the opening. The inner portion is made of a second polymeric material that is more flexible and elastic than the outer material and is in most places of a first thickness and further defines indented rings wherein the second polymeric material is thinner than the first thickness, thereby enabling an installer to begin and propagate a tear about an indented ring.

The present invention is a reliable and simple to install device for protecting of passages for utilities in roof structures from the entry of adverse effect outdoor weather elements. The device is composed of: a flexible tube component (FTC), a surface insertion tube component (SITC), a surface connection plate component (SCPC) and a SCPC-connecting paste component. FTC is composed of a hollow semi-flexible tube having one side unconnected and the other side firmly connected to the SITC, forming a continuous tube. The SITC is composed of a rigid hollow tube divided into two portions by the SCPC. The SCPS is composed of a perforated, rigid material, perpendicularly fixated to and around the SITC, In installing the device of the present invention, the SCPC-connecting paste component is smeared on the external surface of a roof structure surrounding the passage for utilities. The unconnected side of SITC is inserted into the passage for utilities till the SCPC is tightly pressed into the SCPC-connecting paste component. The SCP is pressed until the SCPC-connecting paste component oozes through the perforated plate of the SCPC. Upon drying and hardening of the SCPS connecting paste component, the SCPS is fixated and the device is stabilized. After the device is fixed and stabilized the FTC is stretched and bent in an approximately 180 degree angle so as to have the unconnected opening of the FTC approximately aligned in parallel with, and facing the external surface of, a roof structure surrounding of the passage for utilities. Either after the bending of FTC or prior to starting the installation of the device, utilities can be inserted through the FTC and SCPS.

A ventilation device is supported in at a ventilation opening in a fabric panel of a building in which the fabric panel is supported under tension across a frame. The device includes a lower frame and an intermediate frame with respective flanges that receive a perimeter edge of the fabric panel about the ventilation opening therebetween. A cover is joined to the frames so as to prevent precipitation entering the frame opening while providing exterior ventilation from the ventilation opening of the building through one or more exterior openings in the cover.

A roof mount assembly mounts a structure to a roof having 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.

A roof mounted diverting device for diverting a direction of flow of gas from a roof-penetrating pipe is provided. The roof-penetrating pipe has a central axis. The device includes a diverter having a lower opening and an upper opening, the upper opening having a central axis; and a seal having a seal opening, the seal opening being con figured to contact an outer surface of the roof-penetrating pipe and form a gas-tight seal with the roof-penetrating pipe. In an assembled state of the device, any of the gas that enters the diverter can only exit the diverter through the upper opening or through the roof-penetrating pipe, and the diverter is installable in multiple different positions, each of die different positions having a different included angle between the central axis of the upper opening and the central axis of the roof-penetrating pipe.

A sloped roof vent has a coated steel plate with a raised center and a gasket receiver is formed around a central hole. A structural body is crimped with a gasket in the receiver. The body has an outer wall extending downward over the receiver. A sloping wall extends inward and a vertical wall supports a second sloping wall with an inner rim. A damper staked to an axle covers the rim. Inserts keep the damper from chattering and fully closing. Wind walls prevent outer drafts from lifting the damper. Two fasteners attach caps to the outer wall. Lanced and pressed ledges on a push-in hose connector permanently engage windows on the inner rim of the structural body. A snap-in screen and a hose connector reducer complete a package.

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.
