FIELD OF THE INVENTION [0001] The present invention relates to a flashing suitable for flashing, for example but not limited to, the roof of a building. BACKGROUND [0002] Many forms of flashing are known. Traditionally flashings were formed from sheets of lead and were conformed on site to shapes required. Lead is both heavy and expensive and requires a lot of labour. It is also difficult to have it satisfactorily retain a painted surface. [0003] Other methods of flashing a roof, such as a ridge of a roof with ridge caps or tiles requires pointing or rendering in the form of cement or mortar, which over time breaks down and cannot move with the expansion and contraction of the building. The application and maintenance of such constructions is time consuming and expensive and may account for a large percentage cost of the final roof structure. [0004] The present invention recognises the prospect of providing lightweight roof flashings that are versatile as to their use (even though they may be pre-shaped for convenience) and demand little in the way of skill in their use. It is to this that the present invention is directed. [0005] I have determined that an effective conformable region of a flashing structure can be prepared by associating a conformable yet shape retaining layer having a mesh, perforate or other "open" character (e.g.; partially expanded sheet aluminium of a "mesh" character) using an appropriate adhesive bonding with a flexible weathering layer and thereafter relying on a tack retaining adhesive surface (whether simply "show through" adhesive or adhesive in addition) for associating such a conformable region to a surface of a region to be flashed. [0006] There are instances however where it is desirable to have part of a roof flashing underlying a ridge cap, tile or member. Nevertheless there is a need, since it is the transition of a roof (whether a ridge, valley or other transition) that is to be flashed, for there to be continuity in the weathering surface. Other instances exist where no ridge cap, tile or member is utilised and the flashing therefore forms the complete ridgeline. [0007] The object of the present invention is to provide a roof flashing for a ridge, valley or otherwise that goes someway to meeting the above desiderata, or at least provides the public with a useful choice. BRIEF DESCRIPTION OF THE INVENTION [0008] In one aspect the present invention may be said to broadly consist in a roof flashing for or suitable for flashing a "ridgeline", said flashing comprising or including: [0009] a) a "ridge" overlying region to overlie the actual or phantom "ridge" to be flashed, [0010] b) a first flanking region extending from the ridge overlying region, and [0011] c) a second flanking region extending from the ridge overlying region, [0012] wherein the ridge overlying region is conformed to a three dimensional form and/or is conformable to a three dimensional form, [0013] and wherein the first and second flanking regions extend from the ridge overlying region so as to flank the actual or phantom "ridge" to be flashed by the flashing, [0014] and wherein the flashing is at least in part laminated so as to have a weathering surface of one or more material(s) and having in at least one of the flanking regions at least a partial underlying support of the weathering material(s). [0015] In one embodiment each of the flanking regions has at least a partial underlying support of the weathering material(s). [0016] Preferably said first and second flanking regions depend from a first zone of articulation immediately adjacent said ridge overlying region. [0017] Preferably at least one of the flanking regions is at least conformed to a three dimensional form, is conformable to a retained or retainable three dimensional form or has a distal extremity greater in extent than the proximal extent of that flanking region to said ridge overlying region. [0018] Preferably the roof flashing includes preferably by removal of a release sheet or release sheets to reveal an adhesive or other tack providing surface to allow at least part of at least one of the flanking regions to be adhesively attached to a support surface e.g. of a roofing material to be flashed. [0019] In some options one or more materials e.g. as a laminate, provide the ridge overlying region whilst in other forms the ridge overlying region can be at least in part, primarily or wholly of the one or more material(s) providing a weathering surface notwithstanding the fact that the flashing is at least in part laminated (e.g. whether solely in one or both of the flanking regions or otherwise). [0020] Preferably the distal ends of one or each of said first and second flanking regions distal from said "ridge" overlying region is conformed into a three dimensional region to allow (by conformity or material thus made available) association with undulating or otherwise three dimensional roofing materials, to be flashed, flanking said "ridge" or "ridgeline". [0021] Preferably said three dimensional region is at least in part held in its three dimensional form by said partial underlying support. Continue reading...
