Description

1 242057' Ridge Tile Roof Ventilation System and Fixing The present

invention relates to methods and apparatus for fixing and or ventilating a tiled roof in the region of the ridge.

It is known to secure ridge tiles to a pitched roof by the use of a ridge batten. The ridge batten is secured along the apex of a series of roof trusses by a number of spaced apart metal straps, each strap being secured over the ridge batten and to either side of a respective truss. Adjacent ridge tiles are slightly separated and held down by a plastic member which is nailed to the ridge batten between the ridge tiles.

It is further known to provide a vent for the roof space via such a ridge tile fixing arrangement. Typically vent strips are located between the lateral edges of a series of ridge tiles, and the upper surface of the top row of roof tiles.

Several problems are associated with this prior arrangement. Typically the ridge tile fixing and ventilation system is supplied to a builder as a kit of parts. The builder must bend a metal hoop to fit the angle of the roof trusses, and then secure each hoop to the roof rafters to hold the ridge batten in place. Once the ridge batten is in situ the vents must be placed on the pitched roof tiles and a ridge tile located thereon to prevent the vents from sliding down the pitched roof. The ridge tile is then fixed to the ridge batten by nailing through the plastic member into the ridge batten. The ridge batten has poor sideways stability because it is located on the apex of the trusses, and it is difficult to ensure tight fixing of the straps. Furthermore the ridge batten is poorly supported between adjacent trusses and thus flexes during nailing, which often results in an insecure fixing.

What is required is an improved ridge tile fixing and ventilation system.

According to a first aspect of the invention there is provided a ridge tile fixing kit comprising a ridge clip and a weather strip, the ridge clip being an unitary item comprising a body having two opposed legs connected thereto, each leg being bendable with respect to the body and having a waist for trapping the clip between adjacent roof battens in use, and the body including an upstanding receiving portion on one side adapted to receive an elongate fixing of a ridge tile; and the weather strip comprising a flexible planar member for covering the gap between and beneath adjacent ridge tiles, and an upstanding limb adapted to pass between adjacent ridge tiles and having opposite projections adapted to extend over adjacent ridge tiles; the limb also having a passage adapted to receive an elongate fixing for the receiving portion of said clip.

Such a kit permits secure fixing of ridge tiles without mortar. The legs of the ridge clip are secured over the apex of a roof truss, or between adjacent roof trusses, and held in place by the uppermost roof tile batten on each side of the ridge, or by an additional batten on each side placed above the uppermost roof tile batten. The legs are preferably flexible to permit the clip to be twisted into place after the battens are fixed. The waist is preferably sized to suit standard battens so as to give an adequately tight fit. Since the uppermost battens are fixed to the sides of the truss rather than the apex, they have greater stability. Furthermore fixing is conventional, by for example nails, and the

straps of the prior art are avoided.

In the preferred embodiment the ridge tile clip is moulded of plastic, and the legs are connected to the body by a living hinge. Preferably an upstanding receiving portion of different height is provided on either side of the body, so that by bending the legs into the opposite direction, the height of the receiving portion can be selected to suit two different heights of ridge tile.

The or each receiving portion preferably comprises a tubular portion adapted to receive a fixing screw. In the case of opposite receiving portions, both may be tubular and have a single aligned through hole for a fixing screw. Other elongate fixing means are possible provided that sufficient engagement gives a secure fixing; a cylindrical fixing with external teeth may for example be pressed axially into place.

In the preferred embodiment the weather strip is also moulded of plastics, the planar member being relatively thin so as to be conformable to the contour of any suitable ridge tile. Preferably the planar member overlaps the ridge tile edge on each side by 10 mm or more.

The upstanding limb preferably comprises a plurality of spaced fingers so as to improve flexibility of the planar member whilst defining a separation gap between adjacent ridge tiles.

On the outer side, in use, the planar member preferably defines one or more longitudinally extending low walls on either side, the ridge tiles sitting in use on said walls, and the walls defining a run-off channel for water passing between adjacent ridge tiles. In the preferred embodiment two spaced walls are provided on either side of the upstanding limb.

At the midpoint of the limb, a fixing passage is provided for alignment with the receiving portion of one of said ridge clips. The passage is preferably of sufficient size to permit elongate fixing to pass therethrough with clearance.

In the preferred embodiment, the limb includes opposite projections on either side of said fixing passage. In use the planar member and projections engage on either side of each adjacent ridge tile so as to sandwich the edge in use, and to hold the planar member in intimate contact with the inside of the ridge tiles by virtue of the inherent resilience thereof.

Each end of the weather strip may further include a relatively thin flap adapted to protrude beyond the lateral ridge tile edges. Such a flap may for example be the same width as the planar member and extend for about 20 mm with a thickness typically 50% or less of the thickness of the planar member; this kind of flap ensures improved seating on roof tiles or roof tile ventilators, and may provide improved draught sealing.

According to a second aspect of the present invention there is provided a ventilator for a tiled roof and adapted for fitment between a roof tile and a ridge tile, the ventilator comprising two arms substantially at right angles and defining a ventilation aperture therethrough from an outer opening at the free end of one arm to an inner opening at an end of the other arm, the ventilator being adapted to lie in use along the top edge of a roof tile such that said one arm is over the outer face of the roof tile and is adapted to support a ridge tile, and said other arm is over the adjacent end of the roof tile and in contact with said end over the entire length thereof.

In this specification by tiled roof we mean a roof covered with tiles, slates, shingles or the like.

A ventilator so arranged can be placed along the top edge of the top row of roof tiles on a pitched roof and by virtue of the other arm will not slide down the pitched roof whilst ridge tiles are fixed. Preferably the ventilation aperture is defined by a row of channels defined by depending walls aligned generally perpendicular to the other arm. Such channels are typically 5 mm x 7 mm and have a length of 70 mm or more. Such a ventilator allows ventilation without ingress of rain for a range of roof pitches.

Preferably the ventilation aperture is defined at least in part by an open channel. In a preferred embodiment the open side of the channel is adjacent the outer face of a roof tile wherein the channel is closed in use on all sides by placing the ventilator on a tile.

An open channel is somewhat easier to mould in plastic. A plurality of parallel open channels are preferred.

In one embodiment the ventilation aperture opens at the free end of the other arm. In another embodiment the ventilation aperture opens substantially at the intersection of the two arms. In a preferred embodiment, the open channel faces down in use, and vents to the inside through the upper surface adjacent the intersection of the arms.

In another embodiment, the ventilation aperture is preferably substantially straight.

The ventilator may be a long strip adapted to lie over several adjacent roof tiles in use.

Alternatively the ventilator may be short whereby more than one ventilator is used to overlie several adjacent roof tiles in use.

The ventilator may be provided with a connector at a side edge thereof for connection with an adjacent ventilator. Such connection of adjacent ventilators is preferably adapted to accommodate lateral expansion due to heat and thus to prevent distortion.

An upper surface of said one arm, which is over the outer face of a roof tile in use, may be provided with one or more upstanding ribs to support a ridge tile, the ribs extending in use in the direction of the ridge.

Preferably a plurality of such ribs are spaced apart on the upper surface of said arm. The portions may be spaced lengthwise andlor widthwise along the surface of the arm.

Spacing in a widthwise manner adapts the ventilator to different sizes of ridge tiles.

The said other arm of the ventilator which is adapted to lie over an adjacent end of a roof tile may include a planar extension along the length thereof. The extension permits the ventilator to be used with curved tiles, and provides support across the width of the tile whilst blocking the inevitable opening between the upper curved surface of a roof tile and the straight lower edge of a ridge tile.

Preferably the ventilator has a line of weakness along the length thereof to permit the extension to be removed by snapping or tearing in case of use with flat roof tiles.

The ventilator may further include a plurality of equal length fingers depending from said other arm wherein the fingers are bendable and adapted to conform to roof tiles in use. The fingers conform to the surface of curved tiles and block the inevitable opening between the upper curved surface of the roof tile and the ventilator which might be accessible by small creatures.

A ventilator according to the invention permits the internal roof space to be vented, or the space between the pitched roof tiles and a membrane to be vented or the ridge tile space to be vented. To vent the roof space an end of the membrane is secured between the ventilator and the pitched roof tiles so that outside air can communicate through the ventilation aperture with the roof space. To vent the space between the pitched roof tiles and the membrane the membrane is laid over the apex of the roof trusses.

According to a third aspect of the present invention there is provided a clip for fixing a ridge tile, the clip being a unitary item comprising a body having two opposed legs connected thereto, each leg being bendable and having a waist for trapping the clip between adjacent roof battens in use, the body further including an upstanding receiving portion on one side adapted to receive an elongate fixing of a ridge tile.

As noted above such a clip can be used to fix a ridge tile to a roof whereby the legs are hinged downwards into a first condition such that the receiving portion extends in an opposite upward direction. The elongate fixing is then located in the receiving portion to secure a ridge tile in place. Furthermore the legs can be hinged into the opposite direction whereby the receiving portion is on the same side. The height of the receiving portion relative to the body is thus selectable to suit different heights of ridge tile.

According to a fourth aspect of the present invention there is provided a sealing strip for bridging adjacent ridge tiles comprising a planar member for covering the gap between adjacent tiles and a limb insertable in the gap, the limb comprising a plurality of spaced fingers whereby the planar member is bendable and adapted to conform to the profile of adjacent roof tiles in use.

As noted above, the fingers of the strip permit the planar member to conform to the shape of the curved tiles. The strip may be adapted to the interior or exterior surface of the ridge tiles but in a preferred embodiment is on the inside so as to be substantially invisible from the outside. The free end of the limb preferably includes oppositely directed projections adapted with the planar member to sandwich the edge of a ridge tile in use. This arrangement holds the ridge tile and strip in intimate contact.

According to a fifth aspect of the present invention there is provided a comb comprising a first arm and a second arm substantially at right angles thereto, the second arm having a plurality of equal length fingers depending therefrom wherein the fingers are bendable and adapted to conform to the outer profile of roof tiles in use.

A comb so arranged permits the fingers to conform to the surface of curved tiles and block the inevitable opening between the upper curved surface of the roof tile and the ventilator which might be accessible by small creatures.

Preferably the first arm of comb is adapted to be connected to the ventilator mentioned above on the underside thereof. Connecting the comb to the ventilator avoid loss of parts and may be particularly useful for a roofer when assembling the comb and ventilator on a roof. The connection may be separable, for example by releasable clip.

The inner face of the first arm may have a foam pad to abut an end of a roof tile and to provide a seal therewith in use.

The comb may include a third arm substantially at right angles to the first arm and parallel to the second arm, this third arm being adapted to engage an upper edge of a roof tile so as to retain the comb in position.

According to a sixth aspect of the invention there is provided a ridge ventilation kit for a roof and comprising the ventilator mentioned above and a weather strip for substantially sealing the gap between adjacent ridge tiles, the weather strip having in part an H section whose free ends are adapted to closely engage the inner and outer surfaces of adjacent ridge tiles, and whose bar is adapted to receive elongate fixings for through attachment to a roof substructure. The substructure may comprise roof timbers or the clip mentioned above.

In an alternative embodiment there is provided a ridge ventilation kit for a roof and comprising the ventilator mentioned above and a weather strip for substantially sealing the gap between adjacent ridge tiles, the weather strip having a substantially T section comprising a stem and a base, the stem having a free end with an out turned hand on each side to engage the outer surface of adjacent ridge tiles, the stem being adapted to engage the edges of adjacent ridge tiles over substantially the entire edges thereof, and the base adapted to closely engage the inner surfaces of adjacent ridge tiles over substantially the entire ends thereof, the stem being adapted to receive an elongate fixing for through attachment to a roof substructure, typically a roof timber or a clip attached with respect to a truss.

A kit so arranged permits the weather strip to be attached to any suitable roof timber, for example an additional horizontal batten fixed on each side above the top tile fixing batten. Such a batten is readily available on a building site and eliminates the requirement for special roof timbers or fixings.

The stem or the bar may have a plurality of preformed holes for said elongate fixings, each hole closed by a piercable membrane. This arrangement permits a roofer to select the most suitable hole for fixing the ridge tile and further provides a guide for passage of the fixing through the stem or bar.

The stem may be provided with a plurality of hands to engage the outer surface of adjacent ridge tiles.

In a preferred embodiment the weather strip is provided with slits or cuts to permit the weather strip to conform to the shape of adjacent ridge tiles.

Preferably the weather strip is provided with a seal to engage the inner surface of a ridge tile in use. Such a seal inhibits against water ingress.

Advantageously the weather strip may be provided with a plurality of seals. The seals may form a channel for rain water to run onto a roof tile. Preferably the channel has a relatively rigid wall adapted to engage on the inner surface of a ridge tile.

The kit may further include a comb as substantially described above wherein the comb is adapted to nest with the ventilator.

Fig. 19 is a general arrangement drawing of the ventilation and fixing components.

Figures 1, 2 and 3 show one side of a ridge the fixing and ventilation system, according to the present invention. Referring to Figure 1 there is shown a perspective view from above and to one side of a ridge tile ventilation and fixing system, generally designated 10. In Figure 1 a conventional roof truss 12 is shown to which is attached a conventional roof batten 14 which is used to support and fix roof tiles 16 in a conventional manner. A ventilator 18 having a substantially L-shaped hollow section is placed along the top edge of the roof tiles 16. The ventilator has a number of air passageways (not shown) between the free ends of the L-shaped section permitting the roof to be ventilated. The ventilator 18 does not require fixings to locate it in situ because one arm 20 of the L-shaped section is located over the top edge of the roof tiles 16.

Also shown in Figure 1 is a fixing arrangement for a ridge tile 22. The fixing arrangement is provided by a further roof batten 24 which is located above the arm 20 of the ventilator 18. The roof batten 24 is of a conventional kind and in this embodiment is identical to the batten 14. The ridge tile 22 is placed onto the ventilator 18 and a weather strip 26 is located on the curved end thereof. A subsequent ridge tile 27 is abutted against the strip 26 thereby providing a seal between the two ridge tiles 22, 27. The ridge tiles 22, 27 are fixed in place by a fixing such as a nail 28 which is pierced through the strip 26 and received in the batten 24, which is as rigidly located as any other roof batten.

Referring to Figures 2 and 3 there are shown side views of the system of Fig. 1 according to alternative arrangements for ventilating the roof In Figure 2 a roof membrane 30 is shown between the roof truss 12 and the roof battens 14. A free end 32 of the membrane 30 overlaps the apex. In this arrangement the space 34 between the tiles 16 and the membrane 30 is vented to the outside. It may be necessary to fix the battens onto timber strips nailed on the upper surface of the truss so as to sandwich the membrane; this arrangement ensures that the space under flat tiles is ventilated from top to bottom.

In Figure 3 the free end 32 is placed between the ventilator 18 and the top row of roof tiles 16. In this arrangement the roof space 36 is vented to the outside.

In Figure 4 the arrangement for fixing the ridge tiles 22, 27 to the further roof battens 24 is shown. The gasket 26 is adapted to permit the nails 28 to be passed therethrough and to be received in the further battens 24. The roof tiles and ventilator are omitted for reasons of clarity.

Figures 5, 6 and 7 refer to the weather strip or gasket 26. In Figure 5 an end view of the gasket 26 is shown sealing two ridge tiles 22, 27. The nail 28 is shown passing through the gasket 26. In Figure 6 the gasket 26 is shown to comprise of segments 38 to permit the gasket 26 to be bent in the shape of a curve as shown to conform to the shape of a ridge tile 22, 27. Bending of the gasket 26 is facilitated the segments 38 which are separated by spaces 40 as shown in Figure 7. The gasket may be further provided with pre-formed holes (not shown) of the seal to accept nails 28. The holes are preferably closed by a thin membrane which is adapted to be pierced by a nail 28. In this manner a plurality of pre-formed holes can be provided and the roofer can select the most appropriate hole to facilitate fixing to the further ridge batten 24.

Now referring to Figure 8 there is shown a perspective view from above and to one side of a ventilator 18 shown in Figure 1. The ventilator 18 has a substantially L-shaped section. A shown in Figure 8 the free ends of the L-shaped section are provided with an air communication path 42. The ventilator 18 is shown with an optional extension 44 for use with curved tiles. The appendage 44 is provided with a line of weakness 48 to permit it to be removed by, for example, snapping.

In Figure 9 the appendage 44 is shown in use with curved tiles 46. An option comb 50 of the ventilator 18 is also shown to prevent birds entering the space between a curved tile 46 and the ventilator 18.

Figure 10 shows an alternative arrangement for the weather strip 26 shown in Figure 7, generally designated 60. In Figure 10 the weather strip 60 has an inner part 62 and an outer cover 64. The outer cover 64 is provided with elongate holes 66 to receive fixings (not shown). The inner part 62 has channels 68 for rain water. In use, the cover 64 is adapted to engage the inner part 62 by way of curved edges 70 of the cover 64. The cover 64 permits the weather strip 60 to be pre-formed prior to fitment to a ridge tile.

The channels 68 are adapted to engage an inner surface of the ridge tiles and prevent water ingress. Rain water entering the weather strip 60 runs off onto roof tiles via the channels 68.

Figure 11 is a perspective view from above and to one side of an alternative embodiment to the ventilator of Figure 8, generally designated 80. The ventilator 80 has a generally L-shaped section comprising two arms 82, 84. The arm 82 substantially comprises a thin plate and is adapted to lie over an end of a roof tile. The arm 84 is adapted to lie over an outer face of a roof tile and includes a series of channels which extend from the free end 86 of the arm 84 to the intersection 88 of the anus 82, 84. In this manner the channels are substantially straight. The ventilator 80 is of such a length to overlie one or a few tiles and is provided with a connector 90 at an end of the ventilator 80 to connect the ventilator 80 to an adjacent ventilator. The arm 84 has an upper surface 91 in use which has three rows of ridges 92, 94, 96 to support an edge of a ridge tile. In Figure 11 each ridge 92, 94, 96 comprises a series of spaced apart ridges.

In Figure 12 there is shown a partial perspective view from below and to one side of the ventilator 80 shown in Fig 11. Figure 12 illustrates the open channels 98 which are closed in use by placing the ventilator 80 on a tile.

Now turning to Figure 13 there is shown a perspective view from above and to one side of an alternative embodiment to the weather strip of Figure 10, and generally indicated 100. The weather strip 100 has substantially a T-shaped cross section comprising a stem 102 for location between adjacent ridge tiles, and a base 104 adapted for contact with inner surfaces of adjacent roof tiles. The stem 102 is provided with a single hole 106 to receive a fixing (not shown) for securing the weather strip 100 in place. The stem 102 is provided with a two hands 108, 110 adapted for contact with outer surfaces of adjacent ridge tiles. The stem has slits 112 to permit the weather strip 100 to conform to the internal shape of adjacent ridge tiles. The base 104 has an outer seal 114 and an inner seal 116 to seal the weather strip 100 to adjacent ridge tiles and thereby inhibit water ingress. Rain water entering the weather strip 100 runs off onto roof tiles via the channels 118, 120. Optionally thin end flaps 119 are provided to extend from the ridge tile over the adjacent roof tiles. These flaps improve sealing against ingress of wind driven water.

Figure 14 shows a perspective view from above and to one side of an alternative comb to the comb of Figure 9. The comb 130 is adapted to nest with a ventilator 80 in a manner illustrated in Figure 15. In Figure 14 the comb 130 comprises two arms 132, 134 substantially at right angles. The comb 130 is conveniently adapted to clip to the ventilator 80 via the arm 134 to avoid loss of parts. The inner face of the first arm 132 is provided with a foam pad 136 to abut an end of a roof tile to provide a seal therewith.

The free end of arm 134 has a series of equal length fingers 138 which are adapted to bend inward in the manner indicated at 140 thereby permitting fingers 138 to remain in contact with curved roof tiles. A tear line 139 permits separation of the portion carrying the fingers in cases where they are not required. The remaining portion can be used in either orientation to seal the top edge or the top end of a roof tile by virtue of the foam pad 136.

In Figure 15 the fingers 138 are shown bent inward to remain in contact with a tile 142.

The foam pad 136 is shown abutting the end of the tile 142. Ridge 92 is also shown supporting an edge of a ridge tile 144.

Now referring to Figure 16 there is shown a perspective view from above and to one side of a clip 160 for fixing a ridge tile. The clip 160 is a unitary moulded item comprising a body 162 having two legs 164, 166 connected thereto with respective living hinges 168, 170. The body 162 has a first receiving portion 172 and a second receiving portion 174 whereby the first receiving portion 172 is longer than the second receiving portion 174. The receiving portions 172, 174 are provided with a common through hole 176 for a fixing.

Figure 17 shows a perspective view from above and to one side of the clip 160 of Figure 16 with the legs 164, 166 hinged into a first condition such that the first receiving portion 172 extends in an opposite direction to the legs 164, 166. The clip 160 can also be bent into a second condition (not shown) such that the legs 164, 166 are hinged in the opposite direction whereby the second receiving portion 174 extends in an opposite direction to the legs 164, 166 in the second condition. Each leg 164, 166 is provided with a respective waist 165, 167.

Figure 18 shows a side view of a fixing system using the clip 160 of Figure 16. Figure 18 shows a truss 178 having two battens 180, 182 fixed thereto. The clip 160 is shown trapped in position via the waist 165, 167between the two battens 180, 182 so that the receiving portion 172 can receive a fixing 184 to secure a ridge tile 186. The clip 160 is bent and twisted into position between the two battens 180, 182 so that either the first receiving portion 172, or the second receiving portion 174 is uppermost. In this manner the clip 160 provides for a degree of adjustment whereby either the first condition or the second condition of the clip 160 is chosen. A degree of adjustment is therefore provided by the clip 160 whereby one of the receiving portions 172, 174 is selected for the fixing 184. The clip can also be placed on a truss so that the legs 164, 166 lie on either side thereof.

It will be appreciated that the specific embodiments are examples of the invention, and that variations are possible within the scope of this application.

Fig. 19 shows a general arrangement of all the components described herein. A roof truss 12 has battens 14 supporting tiles 16. Further battens 180,182 are adapted to engage a ridge clip 160 to which a weather strip 100 is attached by an elongate fixing 184 with waster 185. A ventilator 80 and comb 130 nest below the ridge and against the uppermost edge of the roof tile.
