Shingle with reinforcement layer

A laminated shingle having front and rear exterior surfaces and being comprised of at least two layers of shingle material, one being an anterior layer and the other being a posterior layer, with the posterior layer having front and rear surfaces, a width defined by upper and lower edges and a length defined by right and left edges, the posterior layer 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 thereto, which, together with said base layer of 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;
• and 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 adhered to an exterior surface of said shingle and extending at least substantially between right and left edges of the shingle;
• and
• said reinforcement layer extending at least partially lower than the fastening zone or at least partially into the fastening zone.

A method of making a laminated shingle having front and rear exterior surfaces and having at least two layers of shingle material, one being an anterior layer and the other being a posterior layer, with the posterior layer having front and rear surfaces, a width defined by upper and lower edges and a length defined by right and left edges, comprising making a posterior layer by the steps of:

• (a) providing a base layer of mat having front and rear surfaces;
• (b) providing a coating of asphaltic material on both said front and rear surfaces of the mat;
• (c) providing coatings of granular material on the asphaltic material on said both front and rear surfaces;
• so that the structures of clauses (a), (b) and (c) comprise a first thickness layer;
• (d) providing a longitudinal fastening zone between right and left shingle edges, generally intermediate said upper and lower shingle edges;
• providing an at least partially externally visible generally longitudinal reinforcement second thickness layer of a substantially thinner dimension than said first thickness layer;
• and adhering the reinforcing layer to an exterior surface of the shingle, against the outer surface of the granular material on the surface thereof, extending at least substantially between right and left edges of the shingle;
• having the reinforcement layer extend at least partially lower than the fastening zone or at least partially into the fastening zone;
• whereby
• fasteners applied through the fastening zone will pass through the reinforcement layer.
