Description

FIELD OF THE INVENTION

[0001] This invention relates to a method and assembly for preventing the production of windborne debris from a surface of an object, particularly a roof surface, having roof gravel, under the influence of gale-force winds; and to a method of making said assembly.BACKGROUND TO THE INVENTION

[0002] Reference is made to the seminal article by Minor, Joseph E., Journal of Wind Engineering and Industrial Aerodynamics, 53, (1994), 207-227, entitled “Windborne Debris and the Building Envelope”, for the damaging effects of windborne debris, particularly, roof gravel, in gale-force winds, particularly hurricanes.

[0003] The above reference reported field surveys of typical built-up roofs having conventional “tar and gravel” surfaces that established the average roof gravel size to be 0.6 g., and an average large size to be 5 g.

[0004] While the problem of addressing the damaging effects of flying debris, including roof gravel, on buildings and mobile houses, has been describe...
