Roofing materials

a technology of roofing and materials, applied in the direction of roads, traffic signals, transportation and packaging, etc., can solve the problems of increasing the cooling cost of the roofed structure, exposing the softened layer to foot traffic damage, and affecting so as to improve the reflectivity and improve the reflectivity of the roof and/or siding

Benefits of technology

The present invention relates to a method of making roofing and siding materials with improved reflectivity. The invention is applicable to all types of roofing and siding materials, including shingles, cap sheet roll roofing, and built-up roofing systems. The invention involves adding a layer of granular material to the surface of the roofing and siding materials, which helps to increase the reflectivity of the materials and reduce the temperature of the roof surface. This can provide benefits such as improved insulation, reduced cooling costs, and increased fire rating. The granular material can be embedded in the bituminous composition or applied to the surface of the roofing material while it is still warm and softened. The invention can be used with various types of roofing and siding materials, including shingles, cap sheet roll roofing, and built-up roofing systems.

Problems solved by technology

Such asphalt surfaces absorb radiation, thereby resulting in increased temperature which can result in thermal degradation of the roofing system and / or increase the cooling costs of the roofed structure.
In warmer regions, the bitumen- or asphalt-based layer can be heated to temperatures that significantly soften the bitumen- or asphalt-based water-resistant layer, thereby exposing the softened layer to damage by foot traffic, as well as damage to an individual's shoes.
As a result of these undesirable consequences of bitumen- or asphalt-based roofing coatings, a layer of granules is typically applied to the surface of the bitumen- or asphalt-based layer.

Embodiment Construction

[0050] Referring now to the drawings wherein the showings are for the purpose of illustrating a preferred embodiment of the invention only and not for the purpose of limiting same, FIG. 1 illustrates a prior art roofing system 10. The roofing system 10 is secured to a roof, roof substrate (e.g., base sheets), or subroof R by any suitable arrangement. The roofing system 10 is a shingle that includes a bitumen- or asphalt-based material 12, 15, a reinforcement material 14 therebetween, and layer of granules 16. The reinforcement material 14 is typically a felt or fiberglass material that is commonly used in the art. The reinforcement material 14 is shown as being fully embedded in the bitumen- or asphalt-based material 12. The granules 16 are illustrated as being partially embedded and secured in the bitumen- or asphalt-based material 12. The granules are typical granules used in roofing materials. The granules are generally derived from a mineral base rock such as greenstone, greysto...
