The roof flashing can include a collar, a base, a foot, and a longitudinal opening. The collar can have a conical shape, and the base can have a top edge and a bottom edge such that the top edge of the base is coupled to a bottom edge of the collar. The foot can be coupled to the bottom edge of the base and extend outwardly from the bottom edge of the base. The longitudinal opening can extend from an apex of the collar to an edge of the foot and can include first, second, and third sections. A width of the longitudinal opening can increase when first and second edges of the opening are pulled away from each other. ## Claims ### Claim 1 A roof flashing comprising: a collar, the collar having a conical shape with an apex and a bottom edge; a base, the base having a top edge and a bottom edge, the top edge of the base coupled to the bottom edge of the collar; a foot coupled to the bottom edge of the base and extending outwardly from the bottom edge of the base; and a longitudinal opening extending from the apex of the collar to an edge of the foot, wherein the longitudinal opening includes first, second, and third sections, wherein the first section of the longitudinal opening traverses a portion of the collar from the apex to the bottom edge of the collar at a point where the bottom edge of the collar is coupled to the top edge of the base, wherein the second section of the longitudinal opening traverses a portion of the base from the top edge of the base to the bottom edge of the base at a point where the bottom edge of the base is coupled to the foot, wherein the third section of the longitudinal opening traverses a portion of the foot from the point where the bottom edge of the base is coupled to the foot to the edge of the foot, and wherein the longitudinal opening has first and second edges such that when the first and second edges are pulled away from each other a width of the longitudinal opening increases to enable the roof flashing to be installable around a pipe which is not capable of receiving the roof flashing over a top thereof. ### Claim 2 (depends on 1) The roof flashing of claim 1 wherein at least one of the collar, the base, and the foot is made of elastomeric material. ### Claim 3 (depends on 2) The roof flashing of claim 2 wherein the at least one of the collar, the base, and the foot includes a reinforcement material for reinforcing the elastomeric material. ### Claim 4 (depends on 3) The roof flashing of claim 3 wherein the reinforcement material is embedded in the elastomeric material. ### Claim 5 (depends on 1) The roof flashing of claim 1 wherein at least one of the collar, the base, and the foot includes a reinforcement material. ### Claim 6 (depends on 5) The roof flashing of claim 5 wherein the reinforcement material is embedded in the at least one of the collar, the base, and the foot. ### Claim 7 (depends on 1) The roof flashing of claim 1 wherein the foot is substantially rectangular. ### Claim 8 A roof flashing comprising: a collar, the collar having a conical shape with an apex and a bottom edge; a base, the base having a top edge and a bottom edge, the top edge of the base coupled to the bottom edge of the collar; a foot coupled to the bottom edge of the base and extending outwardly from the bottom edge of the base; and a longitudinal opening extending from the apex of the collar to an edge of the foot, wherein the longitudinal opening includes first, second, and third sections, wherein the first section of the longitudinal opening traverses a portion of the collar from the apex to the bottom edge of the collar at a point where the bottom edge of the collar is coupled to the top edge of the base, wherein the second section of the longitudinal opening traverses a portion of the base from the top edge of the base to the bottom edge of the base at a point where the bottom edge of the base is coupled to the foot, wherein the third section of the longitudinal opening traverses a portion of the foot from the point where the bottom edge of the base is coupled to the foot to the edge of the foot, wherein the longitudinal opening has first and second edges such that when the first and second edges are pulled away from each other a width of the longitudinal opening increases to enable the roof flashing to be installable around a pipe which is not capable of receiving the roof flashing over a top thereof, and wherein the foot is associated with a reinforcement material. ### Claim 9 (depends on 8) The roof flashing of claim 8 wherein the reinforcement material is embedded in the foot.
