Lightweight composite roofing tiles

A molded composite roofing tile with a front and a back, a top and bottom, and opposite outer sides;

• the tile comprising:
• a) an image section with (1) a plurality of tile or shingle images having (i) bottom edges that establish the bottom of the image section, and (ii) outer sides that establish opposite outer sides of the image section, and (2) a visually distinct divider extending adjacent each of the Images;
• b) the back of said image section having (1) support surfaces at said datum plane, and (2) spaced, non-straight reinforcing ribs extending rearwardly to no further than said datum plane;
• wherein each of the ribs are comprised of a plurality of angularly related line segments and no one rib configuration repeats;
• c) a head lap with (1) an upper waterlock along the top of the image section, the upper waterlock being configured to resist flow of water over the top thereof and for controlled water flow therefrom, (2) laterally spaced fastener-receiving formations, and (3) fastener supports extending rearwardly to said datum plane;
• d) a side water lock along one of said outer sides of the image section;
• and
• e) a side overlap facing rearwardly along the other of said outer sides of the image section, the side overlap being configured for positioning into the side waterlock of an adjacent tile when installed onto a roof.

A molded composite roofing tile with a front and a back, a top and bottom, and opposite outer sides;

• the tile comprising:
• a) an image section with (1) a plurality a tile or shingle images having (a) backsides raised from a datum plane (b) a substantially constant front-to-back thickness, (c) bottom edges that establish the bottom of the image section, and (d) outer sides that establish opposite outer sides of the image section, and (2) a visually distinct divider extending adjacent each of the images from proximate the top of the images to proximate but above the bottom edges;
• b) the back of said image section having (1) support surfaces at said datum plane, and (2) spaced, non-straight reinforcing ribs extending rearwardly to no further than said datum plane;
• wherein each of the ribs are comprised of a plurality of angularly related line segments and no one rib configuration repeats;
• c) a head lap with (1) an upper waterlock along the top of the image section, the upper waterlock having (a) a shelf extending along the length thereof, (b) an uninterrupted upper dam to resist flow of water over the top of the shelf, (c) an uninterrupted side dam to resist flow of water out one side of the shelf, the opposite side of the shelf being open for outflow of water from the shelf, and (d) an interrupted lower dam for controlled flow of water out the bottom of the shelf toward the image section therebelow, (2) laterally spaced fastener-receiving formations proximate the lower dam, the fastener-receiving formations having pre-formed tapered fastener openings and being raised from the shelf to resist water flow into said openings, and (3) fastener supports extending from the back of the shelf to said datum plane;
• d) a side water lock along one of said outer sides of the image section, the side waterlock having a forwardly facing channel substantially along the length thereof from the open side of the shelf to proximate but above the bottom of the image section;
• and
• e) a side overlap facing rearwardly along the other of said outer sides of the image section, the side overlap being configured for side-to-side adjustable positioning into the side waterlock channel of an adjacent tile when installed onto a roof, the channel and side overlap further having complimentary profiles to establish side-to-side self-centering between adjacent installed tiles.
