## Abstract

A roofing material including a substrate having a top face and a bottom face. The roofing material further includes a non-asphalt coating applied to the substrate and an asphalt layer covering at least a portion of the top face. The bottom face is asphalt-free, or substantially asphalt-free.

## Claims

### Claim 1

A roofing material, comprising:
a substrate having a top face and a bottom face;
a non-asphalt coating on the substrate;
an asphalt coating on at least a portion of the top face of the substrate, wherein substantially no asphalt is on the bottom face of the substrate;
a first portion of the substrate is unimpregnated with the non-asphalt coating such that the asphalt coating on the top face of the substrate impregnates the first portion; and
a layer of granules adhered to the asphalt coating.

### Claim 2 (depends on 1)

The roofing material of claim 1 wherein the substrate is at least partially impregnated with the non-asphalt coating.

### Claim 3 (depends on 2)

The roofing material of claim 2 wherein the substrate is at least partially impregnated with asphalt from the asphalt coating.

### Claim 4 (depends on 3)

The roofing material of claim 3 wherein the first portion is greater than 50% of the substrate.

### Claim 5 (depends on 1)

The roofing material of claim 1 wherein the non-asphalt coating forms a discrete layer on the bottom face of the substrate.

### Claim 6 (depends on 1)

The roofing material of claim 1 wherein the non-asphalt coating improves at least one shingle property of the group of tear resistance, tensile strength, nail pull resistance, wind resistance, fire resistance, shingle stiffness, cold curling resistance, masking ability, and shingle water shedding ability.

### Claim 7 (depends on 1)

The roofing material of claim 1 wherein the non-asphalt coating includes at least one of the group of calcium carbonate, viscosity modifiers, dispersants, biocides, acrylic resins, clays, wollastonite, and powdered resins.

### Claim 8 (depends on 1)

The roofing material of claim 1 wherein the roofing material is an asphalt roofing shingle.

### Claim 9

A method of manufacturing a roofing material, comprising:
applying a non-asphalt coating to a substrate having a top face and a bottom face;
coating the top face of the substrate with asphalt, wherein substantially no asphalt is coated on a bottom face;
selectively leaving a first portion of the substrate unimpregnated with non-asphalt coating such that the step of coating the top face of the substrate with asphalt results in impregnating the first portion with asphalt; and
applying a layer of granules on the asphalt.

### Claim 10 (depends on 9)

The method of claim 9 wherein the step of applying a non-asphalt coating includes at least partially impregnating the substrate with the non-asphalt coating.

### Claim 11 (depends on 9)

The method of claim 9 wherein the step of applying a non-asphalt coating includes forming a discrete layer of non-asphalt coating on the bottom face.
