Abstract
A two part pre-fabricated drip edge. The drip edge comprises a front plate 14 secured to an L-shaped back plate 10. The front surface of the front plate carries an adhesive to adhere a finish material on to the surface. The front plate preferably extends beyond the corner of the backplate. The edge of the drip may have a groove 16 to receive a complementary groove on an adjacent drip edge to secure the adjacent drips together. The plates are preferably metallic. The finish material preferably comprises a layer of green mineral stones so that the edge blends in with the roofing felt used on the roof. In use the drip edge is attached to the edge of a flat roof to prevent damage to the edge of the roof through damp.
Description
A Drip The present invention relates a product for use as a rainwater drip at the edge of flat roof structure, commonly known in the trade simply as a "drip".
When renewing or constructing a flat roof of a building, it is usual practice for the roofer to install green mineral drips which consist of mineralised felt cut to size before being turned over a strip of hardboard using a heat gun to adhere the felt to the hardboard.
Use of this conventional method can lead to a number of problems on site. The degree of skill required to form neat, straight drips is very high primarily as it requires the use of a torch gun to heat the felt. It is very easy to overheat the felt and spoil the finish of the facing edge as the bitumen melts. Excessive heat can also lead to scorching of the facia board, particularly when the board is made from white PVC or the like.
Moreover, the method is a time consuming process as it firstly requires cutting the felt to length and then fixing it to the edge of the roof. The hardboard sftips would also need to be fixed and the felt heated and turned over onto the roof. Furthermore, the hardboard is usually thin and, as such, will follow the contours of any uneven edges to the roof.
This can lead to an undesirable wavy finish.
The present invention seeks to alleviate the aforementioned problems with the conventional method of installing a drip by providing a drip which is pre-fabricated off site and which is capable of being mechanically fixed to a new or existing timber decking without the need to use hardboard strips or cut felt. Furthermore the invention provides a drip which can provide an unblemished, perfectly straight finish, irrespective of the evenness of the roof edge to which it is fixed. The finish surface of the drip can be designed to match the finish of the felt, for example, a green mineralised stone finish could be applied to the facing edge of the drip during the production process.
The drip aids functionality by eliminating a time consuming process whilst enabling the drip to be fitted by a semi-skilled operative. Furthermore a reduction in the use of a naked flame is always advantageous from a health and safety perspective.
According to one aspect of the invention, there is provided a pre-fabricated drip for subsequent attachment to a flat roof of a building, the drip comprising a front plate secured to an L-shaped back plate, the front surface of the front plate carrying an adhesive to adhere a finish material on to the surface.
Preferably the front plate is made from metal. Preferably still the back plate is also made from metal. Preferably the finish material comprises a layer of green mineral stones.
Preferably the front plate is secured to the back plate so to extend beyond the corner of the back plate.
Preferably at least one edge of the drip is formed with a groove to receive a grove of a neighbouring drip to secure the drips together.
One embodiment of the present invention will now be described by way of example with reference to the accompanying figures in which Figure 1 is a perspective view of a drip constructed in accordance with the present invention; Figure 2 is a plan view of the drip; Figure 3 is a schematic view illustrating a front elevation of the drip; and Figure 4 is a schematic sectional view of one end of the drip.
Referring first to Figure 1, a drip constructed in accordance with the invention comprises an L-shaped metallic back plate 10 having a front surface 12 to which is secured, by for example spot welding, a metallic front plate 14.
The front plate 14 carries an adhesive to adhere a "finish material" to the front plate. By "finish material" it is meant a material that provides a finish to the front plate that conforms to the appearance desired by the user. For example, commonly it would be expected that the finish material is formed of, or otherwise takes the appearance of, a layer of green mineral stone such that the front plate blends in to the roofing felt.
In use, the facing edge will overhang into the guttering of the building.
As can be seen in figures 1 and 4, the front plate 14 extends beyond the corner of the back plate 10. This is primarily to accommodate different thicknesses of roof felt.
As can be seen in figures 1 and 2, each front corner of the back plate 10 has a groove 16 (it will be appreciated that only one corner is shown in the figures). The grooves 16 allow adjacent back plates 10 to be pushed, and then secured, together such that the apparatus and method can be utilised for any length of roofing by simply adding further drips. Each drip could, of course, be manufactured to a desired length.
It will be appreciated that the foregoing is merely an example of an embodiment and just some examples of its use. The skilled reader will readily understand that modifications can be made thereto without departing from the true scope of the invention.
