Abstract
A roofing system has metal shingles that have formed side lap features that are configured to facilitate alignment of adjacent side lapped metal shingles of a shingle installation along a roofing structure and that couple the metal shingles together and form seals along their side lapped peripheral edges. The metal shingles also can have alignment features that cooperate to align shingles in one course with shingles in a next lower course within their headlap regions.
Claims18
A roof structure, comprising:
- a substrate;
- and
- a plurality of metal roofing shingles positioned over the substrate, wherein each of the metal roofing shingles comprises:
- a body having a plurality of peripheral edges;
- wherein the plurality of peripheral edges of the body include a forward edge, a rear edge, and side edges;
- and
- at least one headlap feature defined along the rear edge of the body;
- wherein the body includes a main body portion defined between the forward edge and the at least one headlap feature;
- wherein each side edge comprises a substantially flat side lap region that is part of the body and extends substantially along an entire length of each side edge;
- wherein the main body portion includes an upper surface that extends between the side edges of the body and is continuously planar from one side edge to an opposite side edge and across the side lap region of each side edge;
- wherein the plurality of metal roofing shingles are configured to be installed along the substrate in courses of the metal roofing shingles with at least one side lap region of one or more metal roofing shingles of a same horizontally extending course of the metal roofing shingles overlapping and lying substantially flat against a side lap region of an adjacent metal roofing shingle in the same horizontally extending course of the metal roofing shingles, and with an upper surface of the at least one side lap region remaining exposed to elements;
- and
- wherein the forward edges of the one or more metal roofing shingles are configured to overlap rear edges of the metal roofing shingles in a lower course of the metal roofing shingles when installed along the substrate to connect the one or more metal roofing shingles to the metal roofing shingles of the lower course of the metal roofing shingles.

A roof structure, comprising:
- a substrate;
- an underlayment positioned along the substrate;
- and
- a plurality of metal roofing shingles positioned over the underlayment;
- wherein each of the metal roofing shingles comprises:
- a body having a forward edge, a rear edge, and side edges;
- headlap alignment features defined along the forward and rear edges of the body;
- and
- side lap regions defined substantially along an entire length of each of the side edges;
- wherein the body includes a main body portion defined between the headlap alignment features of the metal roofing shingle;
- wherein the side lap regions are substantially flat and are part of the body;
- wherein the main body portion includes an upper surface that extends between the side edges of the body and is continuously planar from one side edge to an opposite side edge and across the side lap region of each side edge;
- and
- wherein the side lap regions of the metal roofing shingles are each configured to overlap and lie substantially flat against a side lap region of an adjacent metal roofing shingle when the headlap alignment features of the metal roofing shingles of a higher course of the metal roofing shingles and a lower course of the metal roofing shingles are coupled together;
- wherein the metal roofing shingles of the plurality of metal roofing shingles are configured to be installed along the substrate in a plurality of courses of roofing shingles with a side lap region of one or more of the metal roofing shingles of a same horizontally extending course of the metal roofing shingles overlapping and lying substantially flat against a side lap region of a horizontally adjacent metal roofing shingle in the same horizontally extending course of the metal roofing shingles, and with an upper surface of the side lap region of each of the one or more metal roofing shingles remaining exposed to elements;
- and
- wherein the headlap alignment features defined along the forward edges of the one or more metal roofing shingles are configured to engage with corresponding headlap alignment features defined along the rear edges of the metal roofing shingles in a lower course of the metal roofing shingles when installed along the substrate to connect the one or more metal roofing shingles to the metal roofing shingles of the lower course of the metal roofing shingles.
