US4594819A — Roof flashing for use with roof planking

Claim 1

Independent Claim 314 words

Roof flashing installed on Roof Planking of the type which will form a weather-proof seal at roof valleys which comprises: first and second lengths of roofing board each having an upper surface, a lower surface, a front longitudinal edge and an angled intersecting edge, each board having its upper surface at a slight angle with respect to its lower surface; first and second flashing elements each element having a first flat, roof-engaging surface abutting the upper surface of said one of said lengths of roofing board at the intersecting edge thereof each of said elements having: an integrally formed, downwardly-directed flange portion along one edge of said flat, roof-engaging surface and normal to said surface sand flange portion abutting said front edge of each of the roofing boards; an upwardly directed elongated wall portion integrally formed with said flat, roof-engaging surface and at an edge adjacent said downwardly projecting flange portion and said wall portion lying along said intersecting edge of each of said roofing boards, the upper edge of said upwardly directed wall portion is parallel to an imaginary straight line intersecting the front longitudinal edges of adjacent boards and the upwardly directed wall portion of one flashing element abutting the upwardly directed wall portion of the other flashing element, the downward edge of said wall portion extending upwardly a distance sufficient to contact the generally U-shaped attaching element; an upwardly directed reinforcing wall integrally formed with said flat roof engaging surface at the edge of the flashing element which is opposite the upwardly directed elongated wall portion, said reinforcing wall extending from about said downwardly-directed flange along a majority of the length of edge of the flashing element but terminating at a point removed from the other adjacent edge of the flashing element; and a generally U-shaped attaching element frictionally affixed over the intersection of the two upwardly directed elongated wall portions.

Claim 2

Dependent Claim 314 words

Roof flashing installed on Roof Planking of the type which will form a weather-proof seal at roof valleys which comprises: first and second lengths of roofing board each having an upper surface, a lower surface, a front longitudinal edge and an angled intersecting edge, each board having its upper surface at a slight angle with respect to its lower surface; first and second flashing elements each element having a first flat, roof-engaging surface abutting the upper surface of said one of said lengths of roofing board at the intersecting edge thereof each of said elements having: an integrally formed, downwardly-directed flange portion along one edge of said flat, roof-engaging surface and normal to said surface sand flange portion abutting said front edge of each of the roofing boards; an upwardly directed elongated wall portion integrally formed with said flat, roof-engaging surface and at an edge adjacent said downwardly projecting flange portion and said wall portion lying along said intersecting edge of each of said roofing boards, the upper edge of said upwardly directed wall portion is parallel to an imaginary straight line intersecting the front longitudinal edges of adjacent boards and the upwardly directed wall portion of one flashing element abutting the upwardly directed wall portion of the other flashing element, the downward edge of said wall portion extending upwardly a distance sufficient to contact the generally U-shaped attaching element; an upwardly directed reinforcing wall integrally formed with said flat roof engaging surface at the edge of the flashing element which is opposite the upwardly directed elongated wall portion, said reinforcing wall extending from about said downwardly-directed flange along a majority of the length of edge of the flashing element but terminating at a point removed from the other adjacent edge of the flashing element; and a generally U-shaped attaching element frictionally affixed over the intersection of the two upwardly directed elongated wall portions.

Claim 3

Dependent Claim 27 words

The flashing assembly of claim 1 wherein the downwardly directed flange of each element of roof flashing is provided with openings for the receipt of fastening means.

Claim 4

Dependent Claim 43 words

The flashing assembly of claim 1 wherein said generally U-shaped attaching element has an elongated pair of bead means which are urged together by a spring-like effect for retaining and sealing said elongated U-shaped attaching element to the upwardly directed elongated wall portions.

Claim 5

Dependent Claim 48 words

The roof flashing assembly of claim 1 wherein each of the upwardly directed elongated wall portions extend a sufficient amount toward the direction of the edge having the downwardly directed flange as to allow the upwardly directed elongated wall portions to have an overlaping contact with one another.
