Abstract
An elongate plastics strip includes first and second coplanar wings (2, 4) extending from opposing sides of an upright portion (6), where the upright portion is formed on one side with a resilient lip (8) which overlies one of the wings, such that in use, first and second wings underlie adjacent sections of roof covering (10, 12) and the resilient lip is biased into contact with an upper surface of the roof covering. Preferably the strip includes drainage channels (14, 16) extending along each side of the upright portion which may include longitudinal raised portions(18, 20), formed by a crease, running spaced from and parallel to the raised portion. Also the raised portions may be arranged to contact against a lower surface of a corrugated roof covering. In a further embodiment a resilient lip may be formed on each side of the upright portion (Figure 4) and the gap between the lip and its respective wing may differ in order to accommodate adjacent roof coverings of different thicknesses.
Description
2353051 Roofing Strip The present invention relates to a strip f or f
itting beneath the opposed edges of adjacent coplanar sections of roof covering.
It is commonplace for adjacent coplanar sections of roof covering to be formed from different materials. For example, in a terraced street, some houses may be provided with traditional slate roofs, whereas some houses may instead be provided with more modern roofs formed from corrugated tiles.
Where adjoining sections of roof covering are formed from the same material, it is a straightforward matter to combine those sections into a continuous, seamless covering. However, where the coverings of adjoining roof sections are formed from different materials, a gap is formed between the opposed edges of the two sections through which rainwater may run.
Furthermore, where the edge of one covering section is raised above that of its adjacent section, a gust of wind may drive rainwater or detritus under the protruding edge or, in an extreme case, lift the upstanding edge causing damage to the roof.
Hitherto, the above problems have been overcome by laying an elongate strip of plastics material beneath the opposed edges of two adjoining sections of roof covering, the gap between each section and the underlying surface of the strip being filled by a respective line of mortar or cement. A cha.nnel is thus formed between the two lines of filling material along which rainwater may drain.
However, it will be appreciated that such a process is extremely time consuming and, where the edge of one covering section is raised above that of its adjacent section, the filling material is clearly visible beneath the protruding edge. I I have now devised an arrangement which overcomes the above-mentioned limitations of existing roofing strips.
In accordance with the present invention, there is 2 provided an elongate plastics strip comprising f irst and second coplanar wings which extend from opposite sides of a longitudinally extending upright portion, the upright portion being formed on one side with a resilient lip which overlies one of the wings such that, with the f irst and second wings underlying respective sections of roof covering, the resilient lip is biased into contact with the upper surf ace of its underlying roof covering.
It will be appreciated that the upright portion will conceal any gap caused where the edge of one roof section is raised above the opposed edge of the other roof section, such as is typically found between a section of corrugated roof covering and a section of flat roof covering.
Also, with the strip fitted between a section of corrugated roof covering and a section of flat roof covering such that the resilient lip is biased into contact with the surface of the corrugated covering, the likelihood of the corrugated roof section being lifted by a gust of wind is reduced still further. 20 Furthermore, the strip also saves time normally spent in cutting consecutive tiles, slates, etc., to produce an even edge, as any unevenness along the edge of a roof covering may be concealed beneath the lip. Preferably respective drainage channels extend longitudinally along each side of the upright portion.
Preferably the drainage channels are formed between the upright portion and a longitudinally extending raised portion of each wing. Preferably each raised portion is formed by a crease in its respective wing.
Preferably one raised portion which lies on the same side of the strip as the lip, is arranged to form a catch against which a trough of a corrugated roof cover may abut to inhibit relative movement between that cover and the strip.
Preferably the lip extends firstly upwards from the top of the upright portion and then downwards towards its distal edge. Most preferably the lip extends outwards in an arc from the top of the upright portion. Preferably the lip is slightly upturned along its distal edge to enable the strip to be more easily fitted.
3 It has been f ound to be suf f icient f or a section of flat roof covering to abut its opposed surface of the upright portion to prevent that covering from being lifted by a gust of wind. However, respective resilient lips may be formed on 5 either side of the upright portion.
In this case, different sized gaps may be formed on either side of the strip, between the lips and their respective underlying wings, to accommodate adjacent roof coverings of different thicknesses.
Also in accordance with the present invention, there is provided a method for forming a roof, the method comprising the steps of providing an elongate plastics strip comprising first and second coplanar wings which extend from opposite sides of a longitudinally extending upright portion and installing the strip such that the first and second wings underlie respective coplanar sections of roof covering with the upright portion extending between the opposed edges of the two sections.
Further in accordance with the present invention, there is provided a roof comprising two coplanar sections of roof covering and an elongate plastics strip comprising first and second coplanar wings which extend from opposite sides of a longitudinally extending upright portion, the strip being arranged such that the upright portion extends between the opposed edges of the two sections of roof covering with each wing extending beneath a respective section or roof covering.
Embodiments of the present invention will now be described by way of examples only and with reference to the accompanying drawings, in which:
Figure 1 is an isometric view of a first embodiment of roofing strip in accordance with the present invention; Figure 2 is a vertical section through the strip of Figure 1, when fitted beneath the opposed edges of two adjacent roof sections of roof covering.
Figure 3 is an isometric view of a second embodiment of roofing strip; and Figure 4 is a vertical section through the strip of Figure 3, when fitted beneath the opposed edges of two adjacent roof sections.
Referring to Figure 1 of the drawings, an elongate, 4 extruded plastics roofing strip is shown comprising first and second coplanar wings 2,4 which extend in opposite directions from the bottom edge ides of a longitudinally extending upright portion 6.
The upright portion 6 is formed, along its upper edge, with a resilient arcuate lip 8 which overlies and is spaced from the underlying wing 2 such that, when the strip fitted is in place as shown in Figure 2, with first wing 2 underlying a corrugated tile 10 and the second wing 4 underlying a flat roofing slate 12, the resilient lip 8 is biased into contact with the upper surface of the corrugated tile 10 and thus prevents the tile from being lifted by a gust of wind.
Respective drainage channels 14,16 extend longitudinally along either side of the upright portion 6, between the upright portion and respective longitudinally extending creases 18, 2 0 in the wings 2, 4. The drainage channels 14,16 serve to remove any rainwater water which may leak down between the edges of the roof sections 2,4 and the upright portion 6. 20 When the strip is f itted in place, the crease 18 locates within a trough 22 of the corrugated tile 10 to inhibit relative movement between the tile and the strip. Each side of the strip is fastened at intervals along its length to respective batons e.g. 24,26 which are laid upon a sheet of felt material 28 and extend between rafters e.g. 30,32 on either side of an adjoining wall 34 between two houses.
Figure 3 illustrates a second embodiment of roofing strip in which resilient arcuate lips 8,36 extend from the top edge of the upright portion 6, to overlie the respective wings of the strip. The gap formed beneath the lip 36 is substantially less than that formed beneath the lip 8 to take into the account the difference in thicknesses between a corrugated tile 10 and a flat slate 12 when the strip is fitted in place as shown in Figure 4.
The roofing strips thus described are easily fitted in place to provide a secure and aesthetically pleasing interface between the opposed edges of two adjacent sections of roof covering.
