Definitions

  • the present invention provides a natural stone ridge configured for mechanical fixation to an apex of a roof structure.
  • the present invention also provides a natural stone ridge configured to provide ventilation to a roof space of a roof structure.
  • Roofs are predominantly triangular shaped timber structures with resemblance to a tent or pyramid that sit on the top of a building so as to direct rainwater and snow water away from the building. These structures are covered with a variety of resilient weather proof roof coverings in various forms such as stone, slates, clay and concrete so as to remain waterproof.
  • a roof When installed, a roof has an arrangement of flat sides that lean together.
  • a roof structure typically, there are two different aspects of a roof structures.
  • a first aspect of a roof structure is for example a tent shaped roof as shown in Figure 1 which has two sides that lean together at the upper horizontal edge called a ridge.
  • a second aspect of a roof structure is a pyramid shaped roof as shown in Figure 2 which has four sides that lean together at the angular side edges called hips.
  • Stone has been used in roofing for many hundreds of years, the stone slates are usually formed from sedimentary shale that can be split and then shaped into relatively flat layers.
  • Figures 3 and 4 illustrate roofing formed from stone slates (C) laid onto timber supports of a roof structure (D) to form a resilient roof covering.
  • Ridge tiles (E) are placed at the very top of the roof structure so as to cover the intersection between the different flat plains of the roof.
  • the ridge tiles can be made in several different angles, sizes and colours.
  • Figures 3 and 4 illustrate the use of ridge tiles on two slightly different aspects of a roof.
  • Figure 3 shows a tent shaped roof in which the upper point at which two opposite sides converge is called the apex (marked with "X" in Figure 1 ).
  • Figure 3 illustrates a traditional method of cement bedding a ridge.
  • the ridge tile (E) is an angular piece of stone (having a 90-degree cross-section, forming an upside down 'V') and is set in position over the junction between the two opposite sides at the apex.
  • Cement (F) is used to secure the ridge tile in position, thus forming a weatherproof seal and completing the roof installation.
  • the pyramid shaped roof (as shown in Figure 2 ) is formed when two adjacent sides of a roof meet externally and as a result the junction is a compound angle, and the plane of the junction is shallower.
  • These side ridge junctions are known as a hip ridge and hip ridge tiles and are used to seal this junction typically forms an angle of around 120 degrees.
  • the traditional aspect of the installed stone roof has an extremely desirable aesthetic and, in many areas where these types of roofs are prevalent, the use of traditional stone is required under local authority planning regulations. Angular ridge tiles are however typically hewed from a solid piece of stone. This can be extremely laborious and expensive.
  • roof ventilation systems exist that utilise metal brackets that are mechanically fixed to the roof frame. These brackets are used to fix and locate a ridge runner batten (i.e. a standard length of roofing timber running along the apex of the roof line and directly below the ridge) to which the ridge tiles are mechanically fixed.
  • a ridge runner batten i.e. a standard length of roofing timber running along the apex of the roof line and directly below the ridge
  • preformed plastic joining brackets that are placed onto the end of each tile prior to installation. These joining brackets enable each ridge tile to abut the previous ridge tile whilst at the same time sealing the join and holding the tiles in place.
  • FIG. 4 illustrates the passage of moist air that is drawn through a modern, vented ridge as described above.
  • ridge ventilation systems for use with conventional ridge tiles, for example with concrete or clay ridge tiles, which allow a small gap around the edge of the ridge tiles to enable free movement of air below the ridge tile that carries away moisture.
  • United States patent application number US 2012/0096782 discloses a ridge ventilation system that includes a plurality of ridge vent sections configured to be arranged end-to-end along the ridge of a roof covering a vent slot.
  • Each ridge vent section has an elongated longitudinally flexible top panel with a central portion. Edge portions terminates at extreme edges of the top panel and ventilation grids extend beneath and along the edge portions spaced from extreme edges thereof. The space between the extreme edges of the top panel and the ventilation grids forms or defines an overhang configured to receive edges of shingles in a course of shingles installed next to the vent section and to inhibit the edges of the shingles from rising up.
  • WO-A-97/21007 discloses a roofing ridge (or hip) installation which includes a roof under structure with a pair of outwardly sloping walls which form an inverted V-shaped ridge.
  • a support panel is mounted on each of the walls with the lower end of each support panel optionally terminating in an upwardly facing channel. Tiles such as slates are mounted in each channel.
  • a pressure applying assembly forces the base end of the panels inwards and a cap spans across and covers the upper ends of the panels and assembly.
  • US 2020/048909 discloses another ridge system with a pair of stone slates overlaying a flexible liner.
  • a ridge mounting and ventilation system comprising: at least a pair of flat natural stone slates bonded one to another along their mitred edges to define a ridge, characterised in that the ridge overlays a rigid waterproof backing formed by a glass-reinforced polyester (GRP) liner; and at least one spacer is located at or adjacent each lower edge of the slates to space the lower edge from a surface on which the slates rest to define an opening for ventilating the apex of an installed roof structure.
