Roofing panel system

Claim 2

A panel for a roofing system comprising an elongated and generally rectangular panel plate molded of a low density organic resin foam material, said panel having a relatively thick overlay exposure portion adjacent the butt end and a relatively thin under lay headlap portion adjacent the head end, said panel being tapered in thickness from the butt end of its exposure portion to the head end of the headlap portion and the width of the headlap portion being greater than the width of the exposure portion in overlap, an ornamental configuration formed on the exposure portion of said panel, a shoulder formed at the head end of the exposure portion at the junction with said headlap portion, and a plurality of water control grooves including a plurality of grooves extending from said shoulder to the butt end of said exposure portion, a plurality of grooves formed in the top surface of the headlap portion of said panel with each disposed to run from an intermediate terminus on said headlap portion to said shoulder, said shoulder having a plurality of water distributing grooves disposed in said headlap portion to run laterally across said panel adjacent said shoulder interconnecting the grooves formed in said headlap portion with the grooves in said exposure portion whereby water can run down the roof panel and then be distributed along said shoulder to further run down the panel through the grooves in said exposure portion, each of said lateral grooves extending for only a portion of the width of said panel and not interconnecting and not running to the edges of said panel whereby water can flow laterally across only a portion of said panel and not to the edges of said panel thereby preventing it from flowing along said shoulder to the gaps between the panels.

Claim 3

The roofing panel of claim 1 wherein the plurality of water control grooves are generally parallel and are disposed to permit water run down the fall line of the roof and the lateral water distributing grooves are each formed to distribute water from only approximately one-fourth to one-third of the water control grooves formed in said headlap portion.

Claim 4

The roofing panel of claim 1 wherein a sunlight and weather resistant coating is disposed on at least the exposure portion of the top surface of said panel.

Claim 5

The roofing panel of claim 1 wherein cutting guide lines are embossed on the back surface of said panel parallel to the vertical edges thereof dividing said panels into uniform sections for facilitating the uniform cutting thereof.

Claim 6

A panel for a roofing system comprising an elongated and generally rectangular panel plate molded of a low density organic resin foam material including, an overlay exposure portion defined at the lower edge by the butt end, said exposure portion upper surface having an ornamental configuration, an underlay headlap portion defined at the upper edge by the head end, and being wider in overlap than said exposure portion, a shoulder formed at the junction of the two portions on the head end of the exposure portion, said panel being tapered down from its butt end to its head end in cross-section thickness, a water control system including a plurality of substantially parallel water control grooves running from a terminus intermediate the top surface of the headlap portion to the shoulder of said panel, a plurality of substantially parallel grooves extending from said shoulder to the butt end of said exposure portion, a plurality of lateral water distributing grooves formed in said headlap portion adjacent said shoulder interconnecting the grooves formed in said headlap portion with the grooves in said exposure portion, said lateral water distributing grooves not interconnecting and not running to the edges of said panel and each being formed to distribute water from only one-fourth to one-third of the water control grooves formed in said headlap portion, a sunlight and weather resistant coating disposed on at least the exposure portion of said panel to protect said low density material from deterioration, and cutting marks embossed on the back surface of said panel plates parallel to the vertical edges thereof to divide the panels into uniform sections between said lateral water distributing grooves to both facilitate the uniform cutting thereof and to provide a means for vertical alignment of adjacent panels.

Claim 7

A panel for a roofing system comprising an elongated and generally rectangular panel plate molded of a low density organic resin foam material including, an overlay exposure portion defined at the lower edge by the butt end, said exposure portion upper surface having an ornamental configuration, an underlay headlap portion defined at the upper edge by the head end, and being wider in overlap than said exposure portion, a shoulder formed at the junction of the two portions on the head end of the exposure portion, said panel being tapered down from its butt end to its head end in cross-section thickness, a water control system including a plurality of substantially parallel water control grooves running from a terminus intermediate the top surface of the headlap portion to the shoulder of said panel, a plurality of substantially parallel grooves extending from said shoulder to the butt end of said exposure portion, a plurality of lateral water distributing grooves formed in said headlap portion adjacent said shoulder interconnecting the grooves formed in said headlap portion with the grooves in said exposure portion, said lateral water distributing grooves not interconnecting and not running to the edges of said panel and each being formed to distribute water from only one-fourth to one-third of the water control grooves formed in said headlap portion, a sunlight and weather resistant coating disposed on at least the exposure portion of said panel to protect said low density material from deterioration, and cutting marks embossed on the back surface of said panel plates parallel to the vertical edges thereof to divide the panels into uniform sections between said lateral water distributing grooves to both facilitate the uniform cutting thereof and to provide a means for vertical alignment of adjacent panels.
