Abstract: A roofing system includes a first group of hook fasteners, a second group of hook fasteners, and a roof covering. The first group of hook fasteners is configured to be attached to a first sloped plane of a roof, and the second group of hook fasteners is configured to be attached to a second sloped plane of the roof. The roof covering has a bottom surface, and the bottom surface of the roof covering includes a plurality of loop fasteners that are configured to engage with at least one of the first group of hook fasteners or the second group of hook fasteners. When the plurality of loop fasteners are engaged with the first group of hook fasteners, the roof covering is resisted from moving in a first direction and not resisted from moving in a second direction that is opposite the first direction. When the plurality of loop fasteners are engaged with the second group of hook fasteners, the roof covering is resisted from moving in the second direction and not resisted from moving in the first direction.

Abstract: A mold for manufacturing a corner-shaped simulated stone product has a mold cavity configured to imprint a stone texture on at least a first side face and a front face of the corner-shaped product. The mold also provides a back face with a desirable molded interior angle. The mold cavity can have a flexible edge around a perimeter of the mold cavity to impart a textured surface to a second side face of the corner-shaped product.

Abstract: An apparatus for manufacturing simulated stone products is provided. The apparatus includes a mold having mold cavities. The mold cavities have a first section and a second section that intersect to form a cavity angle. A hopper is configured to introduce castable material into the mold. The hopper and the mold are moveable with respect to each other, enabling them to be selectively engaged with each other. The hopper includes a first funnel wall configured to contact the top of the first mold cavity and to introduce castable material into the top opening of the first section. The hopper has a second funnel wall configured to contact the second section and act as a barrier to close the top opening of the second section of the mold cavity.
