Metal roofing shingle, metal roofing shingle system, and method of installing

Abstract

The present invention is directed to a metal roofing shingle system comprising universal flashing installed as either a ridge cap, hip flashing, or valley flashing and including non-visible double-flanged interlock joints that extend beneath the underside surface of the flashing, the interlock joints are adapted to couple with metal shingles; each metal shingle having a planar segment, a first longitudinal edge segment opposite a second longitudinal edge segment that includes a non-visible double-flanged interlock joint that extends beneath the bottom surface of the shingle, and a first transverse edge segment opposite a second transverse edge segment that includes a non-visible double-flanged compression joint that extends beneath the bottom surface of the shingle; and shingle shaping tools.

Description

FIELD OF THE INVENTION[0001]The present invention is directed to a sheet metal roofing system for installation on a pitched roof beginning at the ridge and ending at the eave, and in particular, it is directed to a sheet metal roofing system that includes a) metal shingles with self-sealing, non-visible interlock joints that provide watertight connections between adjacent shingles without the application of sealant materials, b) universal flashing that includes non-visible interlocking joints adapted to couple with the metal shingles when the universal flashing member is installed as either a ridge cap, hip flashing, or valley flashing, and c) shingle shaping tools that reshape edges of the metal shingles; the combination non-visible interlocking joints, reshaped shingle edges, and an applied paint system providing a sheet metal roofing system having the appearance of slate shingles, terracotta tiles, or like roofing materials.[0002]Water penetration between adjacent metal shingles ...

AI Technical Summary

Benefits of technology

[0011]In still another embodiment, the universal flashing member is installed inverted as valley flashing along the angle where two different roof sections intersect, the inverted interlock joints coupling with intersecting metal roofing shingles to prevent both water and wind damage.

[0013]It is still another object of the present invention to provide a metal roofing shingle with unexposed, interlocking compression joints that provide a watertight connection between adjacent shingles without the application of gaskets, or applied beads of caulk, or like materials.

[0015]It is still another object of the present invention to provide a lightweight sheet metal roofing system that suitable for installation over existing asphalt roofing shingles.

Problems solved by technology

Water penetration between adjacent metal shingles is a well known problem in the art.

Such water problems are most severe in roofs having a moderate pitch, for example between about a 2 in 12 and 4 in 12 roof pitch.

The shallower the pitch, the greater the potential for a roof leak.

Roof leaks can occur by capillary action, among other reasons, and such water penetration is both difficult to detect and difficult to prevent.

Such exposed joints between shingles are pelted with rain, sleet, and snow and are prone to water penetration.
