"ROOF RIDGE CAPPING SYSTEM"
A roof ridge capping svstem comprises a pair of elongate U-section members (6,7) nailed to rafters (1) either side of a roof ridge. Ridge tiles (16) rest on flanges (11) of the members and are held in place by straps (17) which form snap fits with portions on the ends of the flanges (11). Seals are provided under strape (17) which therefore not only locate ridge tiles but seal the joins. The U-shaped members have upstanding portions which locate the nibs of the top line of tiles (24).
"ROOF RIDGE CAPPING SYSTEM"
A roof ridge capping svstem comprises a pair of elongate U-section members (6,7) nailed to rafters (1) either side of a roof ridge. Ridge tiles (16) rest on flanges (11) of the members and are held in place by straps (17) which form snap fits with portions on the ends of the flanges (11). Seals are provided under strape (17) which therefore not only locate ridge tiles but seal the joins. The U-shaped members have upstanding portions which locate the nibs of the top line of tiles (24).
Description
This invention relates to the capping of roof ridges.
It is known to cap tiled roofs with ridge tiles of e.g. concrete or clay which are bedded with mortar onto the roof tiles. Such a system has certain disadvantages because of the quantity of mortar required, subsequent cracking due to settlement and the need for skilled labour. It is also known to employ ridge tiles which overlap, the complete assembly being nailed or otherwise secured to the roof with or without the use of mortar. This is still however somewhat labour intensive and time consuming~
In German Patent Application P28~6025.5 published as ~E-A-2846025 there is disclosed a system utilising a plastics ridge cap provided with flanges which can be nailed to roof battens, the flanges having means for locating the nibs of the top line of tiles on the roof.
While such an arrangement has considerable advantages it does not allow for the use of conven~ional ridge tiles where desired for reasons of economics or e.g. appearance.
It is an object of the present invention to provide a roof ridge capping system in which conventional ridge tiles can, if desired, be employed whilst permitting simple location of such tiles.
Accordingly the invention provides a roof ridge capping system comprising a pair of elongate members securable ; to a roof adjacent to and either side of a ridge thereon, a plurality of capping members positionable over the ridge of the roof to provide a cap therealong, and a plurality of locating elements adapted to pass over the capping members and interlocking with means provided on each of said elongate members whereby to hold said capping members in position.
Thus, whilst conventional capping members, e`.g. ridge tiles, can be employed, it is possible to locate them without the use of mortar. In a particularly preferred arrangement the locating elements serve not only to hold the ridge tiles in place, but to provide a weather proof joint between adjacent rid~e tiles. Thus, the ~o locating elements - which can for example be in the form of bands or straps of a suitable plastics material or a metal - are used in such a way as to bridge the adjacent ridge tiles. The undersurface of each element can, if required, be provided with a separate seal to extend between the element and the outer surfaces of the two ridge tiles. Such a seal is conveniently in the form of a flexible rubber or synthetic rubber strip preferably provided with ridges on the surface facing the the ridge tiles. The strip may be provided with a number of openings so as to engage over lugs projecting from the locating element, the lugs being relatively thin in the longitudinal direction of the ridge and I - 3 - ~ ~5~2 ~
extending between the two ad~acent ridge tiles. The lugs thus further assist in ensuring that the locating element is centrally positioned over the ridge tiles between the joint between two adjacent ridge tiles.
The locating elements may interlock with the elongate members in any desired fashion, but preferably form a snap fit. Thus each member may be formed with a longitudinally extending enlarged portion of e.g.
circular cross section, the locating elements having at either end an inwardly curved and preferably a C-shaped portion adapted to be resiliently engaged over the enlarged portions. The arrangement is preferably such that there can be relative rotation between the C-shaped portions and the enlarged member portions. This permits adjustment of the elongate member orientation to take into account varying roof pitches. The locating element will generally be pre-formed into the shape of an arc or the like, but should have a degree of resilience to account for varying conditions and to permit the engagement with the elongate member.
.
~ Preferably at least one of the elongate members is in ; ~ the form of a generally U-shaped member, one leg of which is in the form of a flange on which the bottom of a ridge tile is to rest, the flange being provided at its free end with the enlarged portion to engage with the locating elements. The other leg is adapted to be secured to a roof rafter by means of nails or the like passing through suitabIe apertures.
The said other leg may be provided with a longitudinally extending abutment facing the said one leg, over which the nib of a tile can be located in the manner disclosed in German Patent Application P2846025.5 aEorementioned. In ~3 5$2~9 general, for a duo-pitch roof, both elongate members will be of this type, although for a mono pitch roof only one will be so formed.
End caps are preferably provided for capping the ends of the ridge.
An end cap may be in *he form of a plate of any desired shape to give the cor-rect outward appearance, provided with a peripheral flange which lies over the end ridge tile to secure the end of the ridge tile and also to provide weather-ing. The plate may be secured to the elongate member by means of screws or like ; fasteners. In a particularly advantageous arrangement an enlarged portion for engagement with the locating elements has a bore extending therethrough in which such a screw or the like may engage. The inner surface of the bore may be of castellated cross section to assist in grlpping the screw. The outer surface of the plate may be provided with markings simulating tile slips used in conventional ridge capping.
The ridge capping system above described can be used in combination with a verge system of the general type disclosed in German Patent Application P2846275.1 published as DE-A-2846275 and in particular with the improved verge member disclosed in PCT Patent Application PCT/GB80/00205, dated 28th November 1980 (Publication No. W081/01583, Marley Tile A.G.) claiming priority from United Kingdom Patent Application 8024lO3 and 7940986. In such an arrangement 20 the elongate member of the ridge system is provided at its free end with a longitudinally ex~ending slot so that a box-like verge member can be slid onto the member with its upper end securely located and supported. The ridge system end cap will then cover not only the ridge tiles and elongate members but also the upper end of the verge member. Tongues on the verge member overlie the end cap to assist in location.
.. ~, The various components can all be made from a suitable plastics material or a metal by any convenient moulding technique. The elongate members are preferably extruded in continuous lengths. As with the systems disclosed in German Patent ~pplication P2846025.5, filler units rnay be employed to improve the weathering of tiles where such are located in the U-shaped elongate members. Such filler units could be made of a dense explanded plastics foam, contoured to the shape of the tiles, or be other units of the type disclosed in German Patent Application P2846025.5O
An embodiment of the invention will now be described by way of example and with reference to the accompanying drawings, in which:-Fig. 1 is a perspective view of part of the ridg-e of a roof, embodying a capping system in accordance with the invention.

Referring now to the drawings, the roof shown includes wooden rafters 1 and 2 meeting at the ridge and joined together in a conventional fashion with a plate 3.
To the rafters are secured wooden tile battens 4 and 5, again in a conventional fashion with e.g. nails. Roofing felt, not shown, will generally be held in place by the batten nails. Either side of the ridge is secured an elongate member, 6,7, by means of nails 8, passing through slots 9 into the rafters 1 and 2.
As shown in Fig. 3, each member is of U-section being of extruded plastics material. Each member has a ~ottom flange 10, having the apertures 9, and a top flange 11. The bottom flange 10 is provided with an upwardly projecting por-tion 12 of ramp-like formation, having an inwardly directed face 13. The outermost end of the top flange 11 is provided with an enlarged portion 14 of circular cross section, provided with a castellated bore 15 along its length.
Conventional ridge tiles 16 are placed along the ridge with their lower edges resting on upper 1anges 11 of members 6 and 7. The ridge tiles are held in place by means of locating straps 17 provided at the joins between two adjacent ridge tiles. The straps are of a flexible plastics material. At each end of a strap 17 is provided an inwardly curved portion 18 adapted to snap over the portions 14 on flanges 11. Thus straps 17 pass over the ridge tiles and hold them down. Along the centre line of the strap 17 are provided lugs 19 which pass between the two adjacent ridge tiles to ensure that strap 17 is centrally positioned. There are also provided flanges 20 which pass between the ridge tiles but also define C-shaped members with portion 18 so as to assist in locating straps 17 on portions 14 of flanges 11. The arrangement is such I - 7 - ~ g that members 6 and 7 can rotate with respect to straps 17, about the axes of portions 14, to permit roofs of different pitches to be accommodated.
Lugs 19 also serve to locate a seal 21, positioned between a strap 17 and ridge tiles 16, the lugs passing throuqh apertures 22 in the seal. The lower face of the seal - which can be of any suitable rubber or synthetic rubber, is provided with ridges 23 which assist in sealing.
The roof is provided with conventional roof tiles 24 having nibs 25. The next to uppermost line of tiles have their nibs located over battens 4 and 5 in the conventional manner. The uppermost line of tiles, however, extend into the U-sha~ed members 6 and 7 and have their nibs located over portions 12, resting against faces 13. This is effected simply, by pushing the tiles upwardly, as shown in the direction of arrow A on the lefthand side of ~ig. 2. The U-shaped members provided weathering of the upper ends of the top line -20 of tiles and the dimensions are preferably such that the upper flanges 11 bear down on the upper faces of the tiles. Resiliency of members 6 and 7 permits this, and of course permits insertion of the tiles as described above.
As can be seen in Fig. 1, tiles 24 are profiled and to take this into account filler units 26 of expanded plastics foam are provided to ensure complete weathering. Alternativcly, plastics inscrts of U-section could bc use~, one leg being contoured a~ its frec end ~0 match the surface of the tile. The other leg is longer and is trapped behind the upper end of the tile.

At the end of the roof ridge, an end cap 27 is employed.
This end cap has an upper, peripheral flange 28 to locate and weather the last ridge tile on the roof.
The cap 27 is secured by means of screws such as screw 29 (Fig.9) passing through aperture 30 into S castellated bores 15 of members 6 and 7. The end cap has a lower flange 31 to complete weathering and to improve the appearance from underneath r and markings 32 and 33 to simulate tile slips used in conventional ridge systems.
~ 10~ As shown in Figs. 8 and 9, at the end of the roof the ; ridge system interlocks with a verge system described more fully in the PCT ~pplication aforesaid of even date herewith. The verge system consists of box-like verge members 34 which telescopically engage down the verge of the roof. Each member has a channel 35 to receive the edge of a tile ancl provide weathering.
As can be seen, the upper ends of verge men~ers 34 are located behind end cap 27. Each verge member has an end face 36 and to account for this, bottom flànges lO of members 6 and 7 are pro~ided with 510ts 37 to receive the faces, this serving also to locate -the upper ends of verge members 34. Theso slots aro rormed by sawin~ at the point of installation.
embers 34 are provided with portion 38 and 39 to simulate the appearance of a conventional tiled roof, these portions also assisting in the telescopic engagement of two adjacent verge members. The ends of portions 38 and 39 are respectively formed as tongues, 40 and 41 which extend outside cap 27. Thus the verge members are slotted onto the cap 27 as well as onto the flanges 10.
There is thus provided a complete ridge capping and verge system which requires less labour than conventional systems, provides good weathering, and yet simulates the appearance of a conventional roofO

To the rafters are secured wooden tile battens 4 and 5, again in a conventional fashion with e.g. nails. Roofing felt, not shown, will generally be held in place by the batten nails. Either side of the ridge is secured an elongate member, 6,7, by means of nails 8, passing through slots 9 into the rafters 1 and 2.
As shown in Fig. 3, each member is of U-section being of extruded plastics material. Each member has a ~ottom flange 10, having the apertures 9, and a top flange 11. The bottom flange 10 is provided with an upwardly projecting por-tion 12 of ramp-like formation, having an inwardly directed face 13. The outermost end of the top flange 11 is provided with an enlarged portion 14 of circular cross section, provided with a castellated bore 15 along its length.
Conventional ridge tiles 16 are placed along the ridge with their lower edges resting on upper 1anges 11 of members 6 and 7. The ridge tiles are held in place by means of locating straps 17 provided at the joins between two adjacent ridge tiles. The straps are of a flexible plastics material. At each end of a strap 17 is provided an inwardly curved portion 18 adapted to snap over the portions 14 on flanges 11. Thus straps 17 pass over the ridge tiles and hold them down. Along the centre line of the strap 17 are provided lugs 19 which pass between the two adjacent ridge tiles to ensure that strap 17 is centrally positioned. There are also provided flanges 20 which pass between the ridge tiles but also define C-shaped members with portion 18 so as to assist in locating straps 17 on portions 14 of flanges 11. The arrangement is such I - 7 - ~ g that members 6 and 7 can rotate with respect to straps 17, about the axes of portions 14, to permit roofs of different pitches to be accommodated.
Lugs 19 also serve to locate a seal 21, positioned between a strap 17 and ridge tiles 16, the lugs passing throuqh apertures 22 in the seal. The lower face of the seal - which can be of any suitable rubber or synthetic rubber, is provided with ridges 23 which assist in sealing.
The roof is provided with conventional roof tiles 24 having nibs 25. The next to uppermost line of tiles have their nibs located over battens 4 and 5 in the conventional manner. The uppermost line of tiles, however, extend into the U-sha~ed members 6 and 7 and have their nibs located over portions 12, resting against faces 13. This is effected simply, by pushing the tiles upwardly, as shown in the direction of arrow A on the lefthand side of ~ig. 2. The U-shaped members provided weathering of the upper ends of the top line -20 of tiles and the dimensions are preferably such that the upper flanges 11 bear down on the upper faces of the tiles.
