Abstract

A roofing product 24 locatable at the lower part of a tiled roof, the roof having a lowermost course of standard tiles mounted to a lowermost batten 16 and a course of shorter eaves tiles beneath the lowermost course of standard tiles, the product including a locating part 28 profiled to enable mounting on or adjacent a lowermost batten, and a mounting part 42 to mount an eaves tile beneath the lowermost course of standard tiles. The locating part may be an upwardly or downwardly open channel 36. A retaining lip 40 along the edge of the channel opening may retain the batten in the channel. The mounting part may have spaced upper and lower members 44, 68, the upper member being flexible so it can be urged apart from the lower member to receive the upper end of the eaves tile. The lower member may provide a channel 64 for receiving a nib of the eaves tile. The lower member may be flexible to allow the eaves tile to be mounted at a required inclination. A hinge or pivotal area 54 may permit the upper member to pivotally move towards or away from the lower member.

Description

Roofing Product

This invention concerns a roofing product, and particularly a roofing product for use with double lap tiles.

Plain roof tiles, i.e. those without any connecting formations to adjacent tiles, such as slate tiles and a wide range of other material tiles, have to be laid as double lap, with under each layer of tiles another offset layer so that a tile is provided beneath each interface beneath adjacent tiles. At the first and last courses of tiles a shorter eaves tile must be fitted so that the underlying tile layer finishes flush with the above course of tiles.

In shallow pitched roofs the bottom batten which holds the eaves tiles in place, may sometimes be fitted such that its lowest point sits below the top of the fascia board. This can lead to the roofing underlay being inclined upwards towards the fascia at the bottom of the roof line. This configuration can lead to ponding of water on the underlay. This can lead to water ingress.

According to a first aspect of the invention there is provided a roofing product locatable at the lower part of a tiled roof which roof includes a lowermost course of standard tiles mounted to a lowermost batten, with a course of shorter eaves tiles provided beneath the lowermost course of standard tiles, the product comprising a locating part and a mounting part, the locating part being profiled to enable the product to be mounted to the lowermost batten or to be mounted adjacent to the lowermost batten, with the mounting part being profiled to mount an eaves tile beneath the lowermost course of standard tiles.

The product may be elongate and extendible transversely in use across a roof to mount a plurality of eaves tiles.

The product may have a constant cross-section, and may be formed by extrusion.

The locating part may be profiled to enable direct mounting to a roof adjacent to a lowermost batten.

Alternatively, the locating part may be profiled to engage with a lowermost batten.

In one configuration the locating part locates beneath a lowermost batten. The locating part may be in the form of an upwardly open channel to receive a batten.

In a further configuration the locating part locates on top of a lowermost batten. The locating part may be in the form of a downwardly open channel to locate over a batten.

A retaining formation may be provided to retain a batten in the channel, and the retaining formation may comprise a lip running along an edge of the channel opening.

The mounting part may include spaced upper and lower members which face each other and define a space therebetween which can receive the upper end of an eaves tile.

The upper member may be flexible such that the upper and lower members can be urged apart to receive the upper end of an eaves tile, and in a relaxed condition the upper member will urge the eaves tile against the lower member.

A hinge or pivotal area may be provided to permit the upper member to pivotally move towards or away from the lower member.

Formations may be provided on an upper side of the upper member which are engageable in use against the underside of a lowermost course of standard tiles such that the standard tiles urge the upper member against an eaves tile located between the upper and lower members.

The upper and lower members may be profiled to provide a lead in of increased size between the upper and lower members, to facilitate location of the upper end of an eaves tile between the upper and lower members.

The lower member may provide a channel to receive a nib of an eaves tile.

A retaining formation may be provided to retain a nib in the channel, and the retaining formation may comprise a lip running along an edge of the channel opening.

The lower member may be flexible to allow the eaves tile to be mounted at a required inclination.

Fig. 1 shows part of a conventional roofing assembly 10 with standard plain roof tiles 12 arranged in a double lap formation. As can be seen this assembly 10 is relatively shallow. As is conventional shorter eaves tiles 14 are provided at the lower end of the assembly 10, mounted on the lowermost batten 16, which eaves tiles 14 terminate substantially flush with the standard tiles 12 thereabove, to direct water into the gutter 18. As this roofing assembly 10 is relatively shallow, the lowest edge of the lowermost batten 16 is below the top of the fascia board 20. The roofing underlay 22 extends beneath the battens 16 and onto the top of the fascia board 20. As the lowermost part of the lowermost batten is below the top of the fascia board, the underlay 22 between the lowermost batten 16 and fascia board 20 extends gently uphill. This can lead to pooling of water thereon which will tend to lead to water ingress.

Figs. 2-6 show a first roofing product 24 usable at the lower edge of a roofing assembly 26 which is similar to that shown in Fig. 1. The product 24 is in the form of an extruded profiled strip of constant cross-sectional shape. The product 24 has a locating part 28 comprising a strip 30 with first and second upstanding side walls 32,34 extending upwardly from edges of the strip 30 to define an upwardly open first channel 36. The first upstanding side wall 32 to the left as shown in Figs. 2 and 3, is shorter than the second upstanding side wall 34. The second upstanding side wall 34 is of a height approximately equivalent to the thickness of a roof batten 38. A lip 40 is provided on the top of the second side wall 34 pointing back towards the first side wall 32.

A mounting part 42 is provided extending from the opposite side of the second upstanding side wall to the locating part channel 36. The mounting part 42 includes an upper member 44 which curves from the top of the second upstanding side wall 34 and provides a web 46 which is inclined gently downwardly. Three upstanding ridges 48, 50, 52 are provided on the top of the upper member 44, with a one of the ridges 52 provided at the far end of the upper member 44. A hinge point 54 is provided in the underside of the upper member 44 as it curves from the top of the second upstanding side wall 34.

A ledge 56 extends gently downwardly from the second upstanding side wall 34 towards a lower end thereof. The ledge 56 terminates in a third side wall 58 which connects to a strip 60 which terminates in a fourth upstanding side wall 62, with the third and fourth side walls 58,62 and strip 60 defining an upwardly open second channel 64. An inwardly facing lip 66 is provided on the top of the fourth side wall 62.

A lower member 68 extends from the top of the fourth side wall 62 and is inclined gently downwardly, and has an edge 70 of reduced thickness. The upper and lower members 44,68 define a space therebetween with the outer ridge 52 and edge 70 defining a lead in into the space between the upper and lower members 44,68.

In use as shown for instance in Fig. 6 the lowermost batten 16 as shown in Fig. 1 which mounts eaves tiles 14, is omitted. The first product 24 is mounted on the next lowest batten 72. This batten 72 is located in the first channel 36 and will be retained therein by the lip 40. The batten 72 and the first product 24 with the batten 72 mounted in the first channel 36, can be mounted to a roof in a usual manner, and generally by nailing.

The mounting part 42 permits eaves tiles 14 to be mounted thereto as shown. The lead in provided by the upper and lower members 44, 68 permits an eaves tile 14 to be slotted in until the nib 74 therein locates in the second channel 64 as shown for instance in Fig. 5. The lip 66 will tend to retain the nib 74 in the second channel 64, and also permit the nib 74 to pivot for different pitches of roof. The ledge 56 will prevent rotation of the tiles.

Once the eaves tiles 14 are in place, the upper member 44 will tend to flex downwardly to retain the eaves tiles 14 in place. Furthermore, in practice the eaves tiles 14 will generally be located in position first and then the standard tiles 12 mounted proceeding up along the roof. Once the next most standard tile 12 is mounted to the batten 72, this tile 12 will tend to engage via the ridges 48,50,52 against the upper member 44 to prevent the eaves tiles 14 from coming out of the product 24, and particularly the nibs 74 will be retained in the second channel 64.

Figs. 7 to 9 show a second product 76 which is similar in many respects to the first product 24 and has similar upper and lower members 44,68. In this instance the locating part 78 is in the form of a downwardly facing channel 80, with a strip 82 extending from the top of the second upstanding side wall 84 and leading to a shorter downwardly extending side wall 86. The downwardly facing channel 80 can be mounted on a batten 72 as shown in Figs. 8 and 9, and can be mounted thereto by any suitable means such as nailing.

Fig. 10 shows a third product 90 which is similar to the first and second roofing products 24, 76 and includes a similar mounting part 92 shown diagrammatically here. In the third product 90 no separate locating part is provided, rather the product 90 is attached directly to the roof by a nail 94. The nail may be hammered through the strip 96 of the mounting part 92, or preformed mounting holes may be provided in the strip. As shown the third roofing product 90 can be mounted adjacent to what is now the lowermost roof batten 72. With the third roofing product 90 no changes to a conventional roof will be required other than omitting what would conventionally be the lowermost batten.

There are thus described building products which permit eaves tiles to be mounted to, or adjacent to, what is conventionally the one from lowest batten. This enables the roofing underlay to still extend at a downward inclination to the fascia board, as shown for example in Figs. 6 and 7. The building products are of relatively conventional configuration and can thus be readily manufactured by extrusion and located in position as described above in a conventional manner. Eaves tiles can readily be mounted onto the products and securely held thereby, and particularly once the next layer of standard roofing tiles have been mounted on the roof.

Various modifications may be made without departing from the scope of the invention. For instance, the channels may be differently formed. Different features may be provided for retaining the battens and/or nibs in position as appropriate.

Whilst endeavouring in the foregoing specification to draw attention to those features of the invention believed to be of particular importance it should be understood that the Applicant claims protection in respect of any patentable feature or combination of features hereinbefore referred to and/or 5 shown in the drawings whether or not particular emphasis has been placed thereon.
