Abstract

A shingle, a method of making it, and a roof embodying the shingle is provided, in which an exterior surface of the shingle is provided with an attached reinforcement layer through which fasteners may be applied when the shingle is applied to a roof.

First claim

What is claimed is:

1. A first laminated shingle having front and rear exterior surfaces and being comprised of shingle material, with the shingle having a width defined by upper and lower edges and a length defined by right and left edges, the shingle comprising:
(a) a base layer of mat having front and rear surfaces;
(b) a coating of asphaltic material on both front and rear surfaces of the mat;
(c) coatings of granular material on said both front and rear surfaces of the mat, which, together with said base layer of the mat and said coating of asphaltic material comprise a first thickness layer;
(d) a longitudinal fastening zone between right and left shingle edges, generally intermediate said upper and lower edges;
(e) an at least partially externally visible generally longitudinal reinforcement second thickness layer of a substantially thinner dimension than said first thickness layer; said reinforcement second thickness layer being provided on an exterior surface of said shingle and extending at least substantially between right and left edges of the shingle;
(f) said reinforcement second thickness layer being at least partially lower than the fastening zone, toward the lower edge of the shingle or at least partially into the fastening zone toward the upper edge of the shingle; and
(g) when paired with a second shingle, and oriented adjacent the second like shingle in an opposite direction, and bundled with similarly oriented shingles into a stack, a total thickness of the stack will be substantially the same throughout the stack, so the stack of shingles is substantially flat.

2. A plurality of shingles according to claim 1 , wherein the shingles are stacked and bundled, and the stack is flat.

3. A laminated shingle according to claim 1 , wherein the stack has a constant number of mat layers throughout the stack, such that the total thickness of the stack is substantially the same throughout the stack and the stack of shingles is substantially flat.

4. A laminated shingle according to claim 1 , wherein a relative orientation of the shingle and the second shingle in the stack prevents the stack from bowing, such that the total thickness of the stack is substantially the same throughout the stack and the stack of shingles is substantially flat.

5. A laminated shingle according to claim 1 , wherein the weather-facing surfaces of the shingle and the second shingle are oriented in the same manner in the stack.
