Description

This invention relates to a verge capping system for pitched roofs.

The invention provides a verge cap for an edge of a pitched roof of overlapping tiles the verge cap comprising, a tapered channel section member having a base and convergent side walls to receive between them a marginal portion of tiles at the roof edge with one of the side walls overlapping the tiles and the other underlying the tiles, and complementary detent means at opposed ends of the verge cap to inter15 lock the tapered end of the verge cap within the divergent end of an adjacent verge cap and the divergent end of the verge cap around a tapered end of an adjacent verge cap.

The complementary detent means may comprise a resilient tongue projecting downwardly and outwardly from the lower side wall of the verge cap and an abutment on the inner face of the lower side wall of the verge cap so that when the convergent end of one verge cap is inserted in the divergent end of another verge cap, the resilient tongue on the convergent end snaps past and lodges against the abutment to resist separation of the verge caps.

In one arrangement the abutment may comprise an upturned lip on the end of the side wall.

A further upturned lip may also be provided along the free side edge of the side wall adjacent said divergent end of the verge cap to prevent the tongue disengaging from the side wall laterally.

The upper side wall of the verge cap may be formed with a down-turned flange extending part way towards the opposite side wall to close the gap between the upper side wall and upper side wall of a further verge cap telescopically engaging in that verge cap. -2Guide means are preferably provided at the outer side of the convergent and divergent ends of the verge cap to guide a convergent end of the verge cap into the divergent end of the other verge cap moving outwardly with respect to the convergent end of the verge cap.

The guide means may comprise an upstanding fin on the upper side of the convergent end of the verge cap adjacent the base thereof and a guide wall extending along the under side of the upper side wall at the divergent end of the verge cap and spaced from the base of the verge cap to receive the upstanding fin on the convergent end of an adjacent verge cap between the guide wall and base on the verge cap and thereby prevent lateral movement between the adjacent verge caps.

In the case where the upper side wall of the verge cap has a downturned flange at the divergent end therof, the flange is preferably formed with a slot through which the upstanding fin on an adjacent verge cap can pass to engage between the guide wall and base of the verge cap.

Preferably the verge cap comprises sealing means extending lengthwise of one side wall of the tapered channel section member to seal with the upper surface of a tile.

Also according to the present invention there is provided a verge capping system comprising a plurality of interengagable verge caps as hereinbefore defined.

The verge capping system preferably comprises an end stop for attachment to the pitched roof for closing the divergent end of the lowermost verge cap and securing same to the pitched roof structure.

Preferably, the end stop is provided with a resilient tongue which is adapted to snap past and lodge against the abutment of the lowermost verge cap. -3In a modified verge cap, the resilient tongue is formed with a depending locating tab adapted to engage in a slot at the divergent end of an adjacent verge cap to assist relative location of the two Interengaging verge caps.

The verge capping system is preferably such that, in the assembled condition, the locating tab of a verge cap extends through the slot of an adjacent verge cap and is visible to indicate the secure assembly of the verge caps together.

Preferably, the locating tab is push releasable from the slot to assist disengagement of the resilient tongue from the abutment at the divergent end of the other verge cap.

Preferably, a strengthening rib is provided on the base of each verge cap at a location at which it is to be butted by the convergent end of an engaging verge cap to prevent non-interengagement of the detent means (resilient tongue/abutment, locating tab/slot).

Preferably, a plurality of spaced strengthening ribs are provided on the base.

A modified end stop for use with the modified verge cap preferably has a locating tab on its resilient tongue for engaging in the slot at the divergent end of the lowermost verge cap.

The verge capping system preferably comprises a ridge end cloak unit for closing the upper end of the verge capping system at the roof apex and comprising a closure plate for concealing the end of the roof apex, and upper and lower flanges for overlying and underlying respectively the upper and lower side walls of the uppermost verge cap at each side of the roof apex.

Preferably, the upper flange of the ridge end cloak unit has a sealing means extending lengthwise to engage the upper surfaces of the upper side walls of the two uppermost verge caps.

Preferably, the sealing means is a resilient sealing strip having a plurality of downwardly projecting ridges.

Preferably, the lower flange has at its edge remote from the closure -4plate a flange between which and the closure plate the convergent end of the respective uppermost verge cap is laterally located.

Preferably, the lower flange of the ridge end cloak unit, at each end, has a slot adjacent the closure wall to receive the location tab of the resilient tongue of the respective uppermost verge cap.

Referring firstly to Fig. 1 of the drawings, there is shown part of the building having a gable end 20 and a pitched roof 21 having a covering of interlocking roofing tiles 22. The tiles engage over wooden roofing battens 23 supported on rafters (not shown) in conventional manner.

The tiles 22 project over the gable ends of the building and a barge board 24 is mounted on the gable end underneath the projecting edges of the tiles. Each projecting tile edge has a verge cap 25 of the verge capping system of the present invention enclosing the edge of the tile to prevent ingress of moisture and the verge caps interlock one with another to provide a weatherproof finish to the roof. A verge cap will now be described in greater detail with reference to Figs. 2 and 3.

The verge cap 25 is of tapered channel section form having a tapered base wall 26 and upper and lower side walls 27, 28 which converge from end 26A to end 26B of the base wall 26. At the end 26B of the base wall 26 the side walls 27, 28 are joined by an integral end wall 29.

At the wider end 26A of the base wall 26, the upper side wall 27 has a down-turned flange 30 extending a short distance downwardly from the upper side wall 27 with a slot 31 formed between the flange 30 and the adjacent base.wall 26. As best seen in Fig. 3, a guide wall 32 extends from the flange 30 adjacent the slot 31 parallel to the base wall 26.

At the convergent end 26B of the verge cap, the upper side wall 27 is formed with an upstanding fin 33 of similar depth and width to the slot 31. The convergent end 26B of one verge cap 25 is inserted in the divergent end of the adjacent verge cap 25 with the fin 33 on the convergent end 26B passing through the slot 31 to engage between the guide wall 32 and adjacent part of the base wall 26 to lock the verge caps 25 laterally together. -6At the divergent end 26A of the verge cap 25 the lower side wall 28 is formed with a lip 34 extending across the end of the wall and partway along the adjacent free edge of the wall. At the convergent end 26B of the verge cap, the lower side wall 28 is formed on the underside with a downwardly angled resilient tongue 35 which snaps over the lip 34 when the convergent end 26B of one verge cap is inserted into the divergent end 26A of another verge cap to hold the verge caps together.

The underside of the upper side wall 27 is formed with a rubber sealing strip 36 having three upstanding ridges 37 to engage the upper surface of the roof tile over which the verge cap extends and thereby form a seal with the tile to prevent ingress of moisture into the verge cap. Adjacent to the convergent end 26B of the verge cap 25, the base wall 26 is formed with a vertical series of horizontally extending ventilation slots 38 and, to one side of the series of slots 38, a series of vertically spaced holes 39 to provide potential openings for a nail or screw for attaching the base wall 26 to a wooden batten 23 behind the base wall 26 according to the location of the batten.

An end stop 40 (see Fig. 1) is provided to engage in and support the divergent end 26A of the lowermost verge cap 25. The end stop 40 comprises an upstanding wall 41 to engage in the open divergent end 26A of the verge cap member 25. The wall 41 has a downwardly extending resilient tongue 42 corresponding to resilient tongue 35 on the verge cap 25 to snap over the lip 34 when the verge cap is located over the end stop 40. The upper end of the wall 41 has an upwardly inclined part 43 formed along the edge remote from the barge board 24 with an upstanding fin 44 corresponding to the fin 33 oh a verge cap to extend through the slot 31 at the end of the verge cap and engage between the guide wall 32 and the base wall 26. A side flange 45 normal to the wall 41 has holes 46 to permit the end stop 40 to be nailed or screwed to the barge board 24. Thus the end stop 40 locates and holds the divergent end 26A of the verge cap in position in addition to closing same.

The verge cap member of Figs. 4 and 5 is essentially the same as that of Figs. 2 and 3 and consequently like parts are referred to by the same reference numerals with the prefix A, the ends being designated -726A1 and 26B1.

Referring to Figs. 4 and 5 a first difference between the verge cap member 25A of this embodiment and that of the embodiment of Figs. 2 and 3 is that a slot 47 is formed in the lower side wall 28A of the verge cap adjacent to the tapered side wall 26A at the lip end 24A of the lower side wall 28A. In this embodiment the lip 24A is in two parts, one part extending from the base wall 26A and the other part extending along the free edge of the lower side wall 28A, the two parts being separated by a gap 48 at the corner of the lower side wall 28A remote from the base wall 26A. The gap 48 is for drainage purposes.

The slot 47 is adapted to accept a tab 49 on the underside of a downwardly angled resilient tongue 35A of another verge cap, the tab 49 being to one side of the tongue 35A and extending along the tongue 35A from the free end of the latter.

In assembly therefore the tab 49 of one verge cap will engage in the slot 47 of the adjacent verge cap into which the convergent end-of the first mentioned verge cap extends. The purpose of this interengagement of the resilient tongue 35A with the lower side wall 28A is three-fold:(1) It improves location of one verge cap within another since any flexing of the lower side wall 28A which may disengage the resilient tongue 35A from the lip 24A will not affect the location of the tab 49 in the slot 47; The tab 49 is visible through the slot 47 when the verge caps are assembled on the roof and consequently the security of the verge capping system can be visually checked; and If it is ever necessary to dismantle the verge capping system the tabs 49 can be pushed upwards through the slots 47 to disengage the resilient tongues 35A from behind the lips 24A of overlapping adjacent verge caps. (2) (3) -8A second modification to the verge cap 25A is the provision of two ribs spaced along the length of the verge cap and integral with or connected to the base wall 26A between the upper and lower side walls 27A, 28A. These ribs 50 serve to strengthen the verge cap and also assist material flow during the process of injection moulding, i.e. during production of the capping member.

The rib 50 which is nearer the divergent open end 26A1 of the verge cap acts as a stop so that the adjacent verge cap locating into the open end 25A1 cannot be inserted too far in to prevent the location features, i.e. tab 49 and slot 47 and resilient tongue 35A and lip 24A, from engaging.

Referring now to Fig. 6 there is shown an alternative embodiment of end stop 40A which is essentially the same as the end stop 40 described with reference to Fig. 1. In this embodiment however the downwardly extending resilient tongue 42A is provided with a tab 51 which serves exactly the same purpose as the tab 49 on the resilient tongue 35A of each of the verge caps 25A i.e. it engages in the slot 47 in the lowermost verge cap of the verge capping system.

The verge capping system according to the present invention also includes a ridge end cloak unit.

The ridge end cloak units of Figs. 7 and 8 are the same save for their round and angled configurations. They are suitable for use with the verge caps of Figs. 2 and 3. Each is moulded from a convenient plastics material, for example unplasticised polyvinylchloride.

In the following description each component of the two ridge end cloak units the half round ridge end cloak unit (Fig. 7) will have the suffix A added to the reference numerals while the angle ridge end cloak unit (Fig. 8) will have the suffix B added to its reference numerals.

Each ridge end cloak unit comprises a flat plate of plastics material Ϊ 60A or 60B with two flanges namely, a top flange 61A or 61B and a bottom flange 62A or 62B. The top flange in each case is shaped to conform to the outside shape of the ridge tiles employed in the ridge assembly while the bottom flange in each case is designed to interface with the resilient tongues 35 on the two verge caps 25 at the top of -9the roof apex. The backplate 60A or 60B is provided with a central channel 63A or 63B and which is disposed vertically when the ridge end cloak units are in the assembled position. There is disposed.along this channel 63A or 63B a series of blind holes 64A or 64B for receiving securing nails or screws. This channel 63A or 63B is U-shaped in cross-section, i.e. it is open at the outer face of the ridge end cloak unit. The top flange 61A or 61B has under its leading edge a rubber seal 65A or 65B. The seal is formed of a convenient elastomer for example ethylpropylene-diamenemonomare/rubber and comprises three inwardly spaced lips 66A or 66B (Fig. 8) which run the full length of the flange 61A or 61B. The seal is preferably an extruded elastomeric section.

The bottom flange 62A pr 62B of each ridge end cloak unit is provided at its free edge with two upstanding flanges 67A or 67B parallel wih the flat plate 60A or 60B.

The ridge end cloak units of Figs. 9 and 10 are the same save for their round and angled configurations. Each is moulded from a convenient plastics material, for example unplasticised polyvinylchloride. They are suitable for use with the verge caps of Figs. 4 and 5.

In the following description each component of the two ridge end cloak units the half round ridge end cloak unit will have the suffix A added to the reference numerals while the angle ridge end cloak unit will have the suffix B added to its reference numerals.

Each ridge end cloak unit comprises a flat plate of plastics material 70A or 70B with two flanges namely, a top flange 71A or 71B and a bottom flange 72A or 72B. The top flange in each case is shaped to conform to the outside shape of the ridge tiles employed in the ridge assembly while the bottom flange in each case is designed to interface with the resilient tongues 35A on the two verge caps 25A at the top of the roof apex. The backplate 70A or 70B is provided with a central channel 73A or 73B (best seen in Fig. 9) and which is disposed vertically when the ridge end cloak units are in the assembled position. There is disposed along this channel 73A or 73B a series of blind holes 74A or 74B for receiving securing nails or screws. This -10channel 73A or 73B is U-shaped in cross-section. The top flange 71A or 71B has under its leading edge a rubber seal 75B (Fig. 10). This seal is concealed in the ridge end cloak unit of Fig. 9 since the latter is being viewed from its outer face. However in each case the seal is formed of a convenient elastomer for example ethyIpropylenediamenemonomare/rubber and comprises three inwardly spaced lips 76B (Fig. 10) which ruin the full length of the flange 71A or 71B. The seal is preferably an extruded elastomeric section.

The bottom flange of each ridge end cloak unit is provided with two upstanding flanges or ribs 77A or 77B (again best seen in Fig. 10) and two slots 78B (Fig. 10), not seen in Fig. 9, parallel with the ribs 77A or 77B and disposed adjacent the plates 70A or 70B. These two slots are adapted to accept the locating tabs 49 of the resilient tongues 35A (see Fig. 5) of the upper verge caps 25A.

Having described the structural features of the verge capping system, the method of capping the verge of a tiled roof will now be described with reference to Figs, 1 to 3, 7 and 8 and 11 and 12.

A first horizontal row of tiles 22 is laid at the eave of the roof on batten 23 provided and the tiles are nailed to the batten. A verge cap 25 is positioned on the tile with the edge of the tile lying between the end wall 29 and flange 30 of the verge cap. The end stop 40 is located into the divergent end of the verge cap and its nail hole 46 position on the barge board 24 is marked. The verge cap 25 is then removed and the end stop 40 is nailed into position. The end tile is then located into position in the verge cap and the two are offered up to the end stop 40 by positioning in a slightly higher position of the roof and sliding down the roof until the fin 44 on the end stop 40 locates in the end of the verge cap and the resilient tongue 43 has snapped past the lip 24 on the lower side wall 28 of the verge cap. Downward pressure is then applied to the top of the verge cap to hold the seal 36 on the upper side wall 27 of the verge cap firmly in engagement with the upper surface of the tile and a standard roofing nail is driven into whichever of the hole 39 in the base wall 26 of the verge cap is disposed opposite a wooden batten 23 of the roof to fix the base member 26 securely to the roof structure. The next horizontal -11row or course of tiles is laid on the roof and the end tile is located in a further verge cap 25 and located immediately above its final position on the roof and slid down to engage the divergent end 26A of the verge cap over the convergent end 26B of the closely mounted verge cap so that the resilient tongue 35 on the convergent end 26B of the closely mounted verge cap so that the resilient tongue 35 on the convergent end 26B snaps past the lip 24 on the end of the divergent end 26A of the other verge cap and the fin 33 on the convergent end 26B engages through the slot 31 in a divergent end of the verge cap between the guide wall 32 and base wall 26. The newly positioned verge cap is then pressed downwardly to engage the seal 36 on the upper side wall 27 of the verge cap with the upper surface of the tile edge enclosed within the verge cap and the base wall 26 of the verge cap is nailed to the wooden batten 23 as before. This procedure is repeated for each course of tiles up the roof until the roof is fully tiled.

The ridge end cloak unit is then fitted to the roof with all the roof tiles assembled together with all the verge caps members as hereinbefore described and with all the ridge tiles 80 assembled.

The ridge end cloak unit is offered up to the apex of the roof i.e. to the ridge end so that the bottom flange 62A or 62B locates under the two resilient tongues 35 on the top verge caps 25.

By lifting the ridge end cloak unit against the spring pressure of these resilient tongues 35 the top flange 61A or 61B is located on the end of the adjacent ridge tile 80 so that the seal 65A or 65B engages firmly on the outer surface of the ridge tile 80. The bottom of the backplate 60A or 60B of the verge cloak unit is now pushed inwardly towards the ridge so that the two resilient tongues 35 on the verge caps engage the bottom flange 62A or 62B of the ridge end cloak unit between the backplate 60A or 60B and the flanges 67A or 67B.

The position of the ridge tree batten 81, for example is gauged by the workman and the appropriate nail hole 64A or 64B is punctured with a nail or screw which is driven into the end of the ridge tree batten 81 until a sealing washer 82 on the nail 83 is firmly clamped under the head of the latter. -12With the verge caps of Figs. 4 and 5 and the ridge end cloak units of Figs. 9 and 10, in addition to the above assembly procedure, it will be manifest that the tabs 49 of the resilient tongues 35A engage in the slots 78A or 78B. Similarly with the end stops (Fig. 6), the tab 51 will engage in the slot 47 as aforesaid.

It will be understood that water is excluded from the verge of the roof by means of the rubber sealing strip 36 or 36A on the undersides of the verge caps which engage the upper surfaces of the tiles. Water is further excluded from entry into the front of the verge caps by means of the transverse wall 29 or 29A at the convergent end of the verge cap and at the divergent end of the verge cap by the down-turned flange 30 or 30A on the upper end wall which closes the gap between the upper wall of the divergent end of the verge cap and the upper wall of the further verge cap projecting into the first (see Fig. 11).

Water is excluded from entry into the ridge end cloak unit by the sealing strip 65A or 65B (75A or 75B). .
