This disclosure generally relates to seals for roof penetrations, such as sealing adaptors for vents on buildings with metal or non-metal roofs. The roof vent adaptor can provide a generally liquid-tight seal around the roof vent to inhibit or prevent water intrusion into the building.
Roof penetrations are openings in a building's roof, typically to provide access for a system of the building. For example, some roof penetrations allow wires to be routed into the interior of the building to provide electrical power for the building. Some roof penetrations are for vents to allow airflow into or out of the building.
Roof penetrations can be problematic because they can be susceptible to leakage, such as by water or ambient air leaking through the roof penetration. This can result in damage to the building, costly maintenance, a reduction in the building's insulating efficiency, and/or a decrease in comfort for the building's occupants. Accordingly, proper sealing of a roof penetration is desirable.
Certain types of roofs, such as shingle style roofs, typically have a generally planar surface. This can facilitate sealing a roof penetration in such a roof, by allowing a flat seal to flushly engage with the generally planar roof surface of the roof. However, some roofs typically have a generally non-planar surface. For example, corrugated metal roofs may have a generally non-planar surface. Sealing roof penetrations in roofs with a generally non-planar surface can be difficult, ineffective, and/or time consuming because a flat seal may not mate flushly with the surface of the roof, which can allow gaps to remain between portions of the roof and the seal. Nevertheless, it is still desirable to be able to easily, effectively, and quickly seal off penetrations even in roofs with a generally non-planar surface, such as corrugated metal roofs.
This disclosure describes various roof vent adaptors that address at least one of the aforementioned issues, or other issues. In some embodiments, the roof vent adaptor includes a sealing member, such as a sheet of rubber. In some embodiments, the roof vent adaptor includes an outer securing band and/or an inner securing band, such as strips of metal around the outer and/or inner peripheries of the sealing member. In various embodiments, fasteners (e.g., screws) can be passed through the securing bands and secured to the roof. This can compress the sealing member between the roof surface and the securing bands, thereby providing a generally liquid-tight seal around the roof vent to inhibit or prevent water intrusion into the building. In various embodiments, the securing bands can distribute the pressure of the fasteners, which can reduce localized areas of high compression force, increase or strengthen the seal between the sealing member and the roof surface, and/or reduce the chance of the fasteners ripping or otherwise damaging the sealing member.
In certain implementations, the roof vent adaptor is configured to be placed over the roof vent. For example, the roof vent adaptor can be configured to be placed over the roof vent in a direction generally perpendicular to the roof surface. This can be helpful in applications where the roof vent is being newly installed, such as in new construction. In some implementations, the sealing member is substantially uniform, does not include a radially-extending opening, and/or is not configured to be expanded circumferentially (e.g., to wrap around a roof vent).
In certain variants, the roof vent adaptor is configured to be wrapped around the roof vent. For example, the roof vent adaptor can be configured to be mated with the roof vent in a direction generally parallel to the roof surface. This can be helpful in applications where the roof vent is already present, such as when retrofitting an existing roof vent. In some embodiments, the sealing member comprises an opening that extends radially between the aperture and the outer periphery of the sealing member. The opening can expand to enable the roof vent adaptor to be expanded circumferentially. The roof vent adaptor can then be wrapped around the roof vent and contracted circumferentially to engage with the roof vent.
Neither the preceding summary nor the following detailed description purports to limit or define the scope of protection. The scope of protection is defined by the claims.
Various embodiments disclosed herein are described below with reference to the accompanying drawings. The illustrated embodiments are intended to illustrate, but not to limit the scope of this disclosure. Various features of the different disclosed embodiments can be combined to form further embodiments, which are part of this disclosure.
Various improved roof vent adaptors are disclosed. The embodiments disclosed below are described in the context of a roof vent adaptor for sealing a vent in a metal roof, due to particular utility in that context. However, the inventions disclosed herein can also be applied to other types of roofs (e.g., wood, shingle, tar, or otherwise) and for sealing other types of penetrations or apertures (e.g., electrical conduits, drains, structural members, or otherwise). The roof vent adaptors can be configured for use on roofs that are pitched, such as gabled roofs, or non-pitched, such as flat roofs. Some embodiments are configured for use in non-roofing applications. For example, certain embodiments are configured to seal penetrations or apertures in walls, such as exterior walls with masonry or siding.
Certain embodiments of the roof vent adaptors are configured for use with corrugated roofs. Examples of a corrugated roof 100 with roof vent penetrations are shown in
An example of a roof vent adaptor 210 is illustrated in
As shown, the roof vent adaptor 210 can comprise a sealing member 212. The sealing member 212 can be configured to be placed on the roof surface and around the penetration. For example, the sealing member 212 can be placed over and/or around a roof vent. As shown, the sealing member 212 can have a generally flat shape. In certain configurations, the sealing member 212 is made of rubber. In some variants, the sealing member 212 is made of plastic or metal (e.g., aluminum). In some implementations, the sealing member 212 is generally uniform and/or generally continuous in a circumferential direction. For example, as shown, some embodiments do not include a radially-extending gap.
The sealing member 212 can have an aperture 214. The aperture 214 can be configured to receive a certain size and/or shape of vent therethrough. In some embodiments, the aperture 214 is sized and/or shaped to approximately correspond to the outside shape and/or size of the roof vent. For example, as shown, the aperture 214 can be generally rectangular and/or generally square in shape, which can correspond to a generally rectangular and/or generally square vent. In some variants, the aperture 214 is generally circular or generally elliptical in shape, which can correspond to a generally circular or generally elliptical vent. As illustrated in
As illustrated, the sealing member 212 can include an inner border 218 that bounds the aperture 214. Moreover, the sealing member 212 can include an outer border 220 around the outer periphery. Typically, the length of the outer border 220 is greater than the length of the inner border 218. For example, the ratio of the length of the outer border 220 to the length of the inner border 218 can be at least about: 1.7, 1.8, 1.9, 2.0, 2.1, 2.2, ratios between the aforementioned values, or other ratios. As illustrated, in some embodiments, the shape of the inner and outer borders 218, 220 are the same, such as both being generally rectangular and/or square. In some variants, the shape of the inner and outer borders 218, 220 are different, such as the inner border 218 having a generally circular shape and the outer border 220 having a generally rectangular shape, or vice versa. In some embodiments, the inside and/or outside border 218, 220 is generally rectangular (e.g., square), circular, elliptical, triangular, pentagonal, hexagonal, octagonal, diamond-shaped, or other shapes. In certain implementations, the inside and/or outside border 218, 220 is a regular shape. In some variants, the inside and/or outside border 218, 220 is an irregular shape.
In some embodiments, the sealing member 212 includes features to aid in sealing and/or coupling with the roof surface. For example, as shown in
The sealing member 212 can be configured to flex. This can aid the sealing member 212 in conforming to the shape of the surface of the roof and/or the outer peripheral shape of the vent. In some embodiments, the sealing member 212 is configured to flex in the plane of the roof surface and/or perpendicular to the plane of the roof surface. In some embodiments, the sealing member 212 includes a flexible feature, such as at least one gusset 222. As shown in
The roof vent adaptor 210 can include features to aid in securing and/or sealing the roof vent adaptor 210 to the roof surface. For example, the roof vent adaptor 210 can include an inner securing band 224 and/or an outer securing band 226. The securing bands 224, 226 can comprise strips of a material that is harder than the securing member. In some embodiments, the securing bands 224, 226 comprise plastic or metal, such as aluminum. In some embodiments, the securing bands 224, 226 can be generally annular. As used herein, the term “annular” has its normal meaning, such as describing a ring-like shape. The term “annular” can include circular shapes and non-circular shapes. For example, in some embodiments, the securing bands 224, 226 comprise generally rectangular annular shapes (see
As shown in
As also illustrated in
Another embodiment of a roof vent adaptor 310 is illustrated in
As shown in
In some embodiments, the roof vent adaptor 310 has an aperture (not shown). The roof vent adaptor 310 can have an inner border along the aperture and an outer border 320 on an outer periphery. In certain embodiments, the length of the outer border 320 is substantially greater than the length of the inner border 318. For example, the ratio of the length of the outer border 320 to the length of the inner border can be at least about: 6.0, 6.5, 7.0, 7.5, 8.0, 8.5, 9.0, ratios between the aforementioned ratios, or other ratios. In some embodiments, the inside and/or outside border 318, 320 is generally rectangular (e.g., square), circular, elliptical, triangular, pentagonal, hexagonal, octagonal, diamond-shaped, or other shapes. In certain implementations, the inside and/or outside border 318, 320 is a regular shape. In some variants, the inside and/or outside border 318, 320 is an irregular shape.
Some embodiments do not include the aperture 314. As illustrated in
The roof vent adaptor 310 can be used with a variety of sizes and/or shapes of vents. In some embodiments, the sealing member 312 includes a convertible region 330. The convertible region 330 can be in the form of many different shapes and/or can be configured to be adapted to fit a wide variety of vent sizes and/or shapes. For example, in the embodiment shown, the convertible region 330 comprises a plurality of concentric generally rectangular (e.g., square) shapes. Some variants have other shapes, such as generally circular, elliptical, pentagonal, hexagonal, octagonal, diamond-shaped, or otherwise. As shown, in certain embodiments, the convertible region 330 extends radially inward, such as from a gusset 322. The convertible region 330 can include a plurality of convertible elements, such as strips 332. The strips 332 can be configured to be removed from the remainder of the sealing member 312, such as by being cut by a user. This can enable the user to adapt the convertible region 330 to the size and/or shape as needed for a particular use. In various embodiments, removal of a given strip 332 results in the strips that are radially inward of the given strip being removed also.
As an example, the embodiment shown includes a first set of strips 332A, 332B, 332C, and 332D, which are the radially outermost set of strips. To adapt the roof vent adaptor 310 to fit a roof vent having the size and/or shape of the outside periphery of the first set of strips, a user would cut or otherwise remove the strips 332A-332D, thereby adapting the size and/or shape of the aperture 314.
The embodiment shown also includes a second set of strips 332E, 332F, 332G, 332H, which are radially inward from the first set of strips. To adapt the roof vent adaptor 310 to fit a roof vent having the size and/or shape of the outside periphery of the second set of strips, a user would cut or otherwise remove the strips 332E-332H, thereby adapting the size and/or shape of the aperture 314. As shown, the various sets of strips (e.g., 332A-332D, 332E-332H, etc.) can each comprise an annular unit. In some embodiments, the annular units are concentric. For example, the second set of strips can be concentric with the first set of strips and/or other sets of strips.
As illustrated, in some embodiments, certain of the strips are longer than other of the strips. For example, the strips 332A, 332C can be longer than the strips 332B, 332D. As also shown, the ends of the shorter strips 332B, 332D can be received along the length of the longer strips 332A, 332C. The combination of longer and shorter strips 332 can enable the convertible region 330 to be readily converted to at least two different shapes. For example, some embodiments are configured such that removal of certain set of the strips 332 provides an aperture 314 of a first shape and removal of a different set of the strips 332 provides an aperture 314 of a second shape. In the embodiment shown, removal of the strips 332B and 332D would result in an aperture 314 with a generally rectangular shape, and removal of the strips 332A-332D would result in an aperture 314 with a generally square shape. As shown, certain strips can be generally perpendicular to other of the strips. For example, the strips 332A, 332C can be generally perpendicular to the strips 332B, 332D. In various embodiments, the adaptor is configured for use with at least two different roof vent shapes and/or sizes.
The sealing member 312 can include removal features 334. The removal features 334 can be configured to aid in removing a desired one or group of the strips 332 from the remainder of the sealing member 312. In some embodiments, the removal features 334 comprise scores, grooves, weakened areas, or the like. As shown, the removal features 334 can bound (e.g., surround) the strips, such as individually. Some embodiments include indicia, such as indications of size and/or shape. The indicia can be integral with (e.g., molded as a part of) or painted on the sealing member 312. This can aid a user in readily identifying which strips to remove to achieve a certain size and/or shape for the aperture 314.
Another embodiment of a roof vent adaptor 410 is shown in
As shown, the roof vent adaptor 410 can include a sealing member 412, such as a rubber sheet. The roof vent adaptor 410 can include an outer securing band 426, such as an annular metal strip. The outer securing band 326 can have various shapes, such as the shapes discussed above in connection with the securing band 226. In some implementations, the roof vent adaptor 410 is provided and/or used with a strip of material that is divided into segments, called termination strips, to form an inner securing band (not shown), as is discussed in more detail below. The securing bands can be positioned on top of the sealing member 412 and can receive fasteners (e.g., screws) therethrough.
As illustrated, the roof vent adaptor 410 can include a convertible region 430, which can be similar or identical to the convertible region 330. For example, the convertible region 430 can include strips 432 or other portions that are configured to be removed to enable a user to adapt the roof vent adaptor 410 to correspond with a plurality of vent shapes and/or sizes. The sealing member 412 can include removal features 434 to aid in removing a desired one or group of the strips 432 from the remainder of the sealing member 412. For example, as shown in
In some implementations, the roof vent adaptor 410 is generally non-uniform and/or generally discontinuous in a circumferential direction. For example, the roof vent adaptor 410 can have an expanding feature, such as a radially-extending channel 440. In some embodiments, the channel 440 is initially closed, such as the sealing member 412 extending through the channel 440. The channel 440 can be configured to open. For example, the channel 440 can comprise a discontinuity (e.g., a slit, split, gap, seam, perforations, etc.) that facilitate opening the channel 440. Opening the channel 440 can enable the roof vent adaptor 410 to be expanded circumferentially. This can allow the roof vent adaptor 410 to be wrapped around a roof vent. For example, the roof vent adaptor 410 can be configured to be mated with the roof vent radially and/or in a direction generally parallel to the roof surface. This can be helpful in applications where the roof vent is already installed, such as when retrofitting an existing roof vent.
As shown in the cross-sectional view of
As discussed in more detail below, the channel 440 can be configured to engage with a closure unit (see
A method of using a roof vent adaptor is illustrated in
In some embodiments, the method includes obtaining a roof vent adaptor, such as the adaptor 210 described above. The method can include selecting the roof vent adaptor having an aperture that substantially corresponds to the size and/or shape of the roof vent. In some embodiments, the roof vent adaptor includes a sealing member and inner and outer securing bands.
In some embodiments, the method includes placing the roof vent adaptor over the roof vent so that the vent extends through the aperture. For example, the roof vent adaptor can be placed over the top of the vent and moved downward, such as toward the roof surface and/or in a direction generally perpendicular to the roof surface.

As previously mentioned, the convertible regions described herein can be in the form of many different shapes and/or can be configured to be adapted to fit a wide variety of vents. For example, in certain embodiments a convertible region 530 comprises a plurality of generally rectangular (e.g., square) concentric shapes. Some variants have other shapes, such as the generally circular concentric shapes shown in
In certain implementations, the convertible region comprises a non-concentric series of shapes and/or irregular shapes. For example, as shown in
Terms of orientation used herein, such as “top,” “bottom,” “horizontal,” “vertical,” “longitudinal,” “lateral,” and “end” are used in the context of the illustrated embodiments. However, this disclosure should not be limited to the illustrated orientation. Other orientations are possible and are within the scope of this disclosure.
Terms relating to circular shapes as used herein, such as diameter or radius, should be understood not to require perfect circular structures, but rather should be applied to any suitable structure with a cross-sectional region that can be measured from side-to-side. Terms relating to shapes generally, such as “circular” or “cylindrical” or “semi-circular” or “semi-cylindrical” or any related or similar terms, are not required to conform strictly to the mathematical definitions of circles or cylinders or other structures, but can encompass structures that are reasonably close approximations.
Conditional language, such as “can,” “could,” “might,” or “may,” unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain embodiments include or do not include, certain features, elements, and/or steps. Thus, such conditional language is not generally intended to imply that features, elements, and/or steps are in any way required for one or more embodiments.
Conjunctive language, such as the phrase “at least one of X, Y, and Z,” unless specifically stated otherwise, is otherwise understood with the context as used in general to convey that an item, term, etc. may be either X, Y, or Z. Thus, such conjunctive language is not generally intended to imply that certain embodiments require the presence of at least one of X, at least one of Y, and at least one of Z.
The terms “approximately,” “about,” and “substantially” as used herein represent an amount close to the stated amount that still performs a desired function or achieves a desired result. For example, in some embodiments, as the context may dictate, the terms “approximately”, “about”, and “substantially” may refer to an amount that is within less than or equal to 10% of the stated amount. The term “generally” as used herein represents a value, amount, or characteristic that predominantly includes or tends toward a particular value, amount, or characteristic. For example, in certain embodiments, as the context may dictate, the term “generally parallel” can refer to something that departs from exactly parallel by less than or equal to 20 degrees and the term “generally perpendicular” can refer to something that departs from exactly perpendicular by less than or equal to 20 degrees.
Unless otherwise stated, articles such as “a” or “an” should generally be interpreted to include one or more described items. Accordingly, phrases such as “a device configured to” are intended to include one or more recited devices. Such one or more recited devices can also be collectively configured to carry out the stated recitations. For example, “a device configured to carry out recitations A, B, and C” can include a first device configured to carry out recitation A working in conjunction with a second device configured to carry out recitations B and C.
The terms “comprising,” “including,” “having,” and the like are synonymous and are used inclusively, in an open-ended fashion, and do not exclude additional elements, features, acts, operations, and so forth. Likewise, the terms “some,” “certain,” and the like are synonymous and are used in an open-ended fashion. Also, the term “or” is used in its inclusive sense (and not in its exclusive sense) so that when used, for example, to connect a list of elements, the term “or” means one, some, or all of the elements in the list.
Overall, the language of the claims is to be interpreted broadly based on the language employed in the claims. The language of the claims is not to be limited to the non-exclusive embodiments and examples that are illustrated and described in this disclosure, or that are discussed during the prosecution of the application.
