Cap flashing device

摘要

A cap flashing device for overlapping and joining two upper-end pieces of valley flashing within two valleys on a main roof is provided. An adjoining roof forms the two valleys where it meets the main roof. The device comprises a sheet of material having top and bottom surfaces and a raised triangular portion in the material and extending above the material. The triangular portion has a pair of sides in an angled relation to the remaining portion of the material with the remaining portion remaining substantially planar. Upon positioning the material upon the roof, the triangular portion is positioned over the adjoining roof and the remaining portion of the material overlapping and joining the upper end pieces of the flashing thereby inhibiting leakage in either of the valleys with the entire material in complete direct contact with the main roof with the sides being free from any folds or tucks.

1. A cap flashing device for overlapping and joining two upper-end pieces of valley flashing within two valleys on a main roof, an adjoining roof forming the two valleys where the adjoining roof meets the main roof, a valley flashing ridge formed in the valley flashing, the cap flashing device comprising:
a sheet of material having a top surface and a bottom surface, a first edge, a second edge opposite the first edge, a third edge between the first edge and the second edge, and a fourth edge opposite the third edge; and a raised triangular portion formed in a portion of the sheet of material and extending above the top surface, the raised triangular portion having a pair of sides in an angled relation to the remaining portion of the sheet of material, the raised triangular portion defining a first vertex point positioned at the first edge, a second vertex point positioned at the first edge, a third vertex point being the apex of the raised triangular portion positioned at the first edge and in between the first vertex point and the second vertex point, and a fourth vertex point positioned at some point short of the second edge; a planar portion being substantially the portion of the sheet of material remaining beyond the raised triangular portion; a first V-notch formed continuously from the first vertex point to the fourth vertex point being substantially triangular in shape with a first raised side abutting the planar portion, a second raised side abutting the raised triangular portion, the first raised side and the second raised side meeting to form an apex above the planar portion and below the raised triangular portion, the apex when proximate to the fourth vertex point diminishing to meet the fourth vertex point, with no bottom side present so as to receive the valley flashing ridge; a second V-notch formed continuously from the second vertex point to the fourth vertex point being substantially triangular in shape with a first raised side abutting the planar portion, a second raised side abutting the raised triangular portion, the first raised side and the second raised side meeting to form an apex above the planar portion and below the raised triangular portion, the apex when proximate to the fourth vertex point diminishing to meet the fourth vertex point, with no bottom side present so as to receive the valley flashing ridge; wherein upon positioning the bottom surface of the sheet of material upon the roof, the raised triangular portion is positioned over the adjoining roof, the first V-notch and the second V-notch is positioned over the valley flashing ridges, and the planar portion is positioned over the main roof thereby inhibiting leakage in either of the two valleys of the roof, the bottom surface of the sheet of material in complete direct contact with the main roof and the adjoining roof.
