Abstract
In an embodiment, a method includes applying a liquid plural component polymer to a sloped roof to form a protective surface that inhibits moisture seepage to the roof sheathing. In some embodiments, the plural component polymer may be a polyurea compound having a hardening time that is less than approximately 10 minutes. In some embodiments, one or more of the components may be aerated prior to application to the roof substrate. In some embodiments, one or more polystyrene panels may be affixed to the sloped roof prior to application of the liquid plural component polymer. Other embodiments are described and claimed.

A method comprising:
- aerating a polymer liquid comprising polyurea, with an aeration agent to produce an aerated polymer liquid that includes a plurality of cavity regions that are devoid of polyurea within an interior of the aerated polymer liquid;
- applying the aerated polymer liquid as a first membrane layer to a roof substrate of a roof, the roof substrate having a slope and a lateral extent, wherein the applied aerated polymer liquid solidifies to form a first membrane layer that is sloped and has a proximal surface that adheres to the roof substrate over the lateral extent of the roof substrate, wherein a thickness of the first membrane layer is generally uniform over the lateral extent of the roof substrate;
- and
- subsequent to applying the first membrane layer to the roof substrate, applying a second membrane layer comprising a plural component polymer, to the first membrane layer to produce a coated roof.
An apparatus comprising:
- a coating comprising:
- a first membrane layer comprising polyurea applied in a liquid state to a roof substrate having a slope and a lateral extent, wherein the first membrane layer is sloped and has a proximal surface that adheres, upon solidifying, to the roof substrate over the lateral extent of the roof substrate, wherein a thickness of the first membrane layer is generally uniform over the lateral extent of the roof substrate, and wherein the first membrane layer includes a plurality of cavity regions that are devoid of polyurea within an interior portion of the layer;
- and
- a second membrane layer comprising a plural component polymer applied to the first membrane layer.
An apparatus comprising:
- a roof substrate having a slope and a lateral extent;
- a first membrane layer that adheres to the roof substrate upon solidification after application to the roof substrate in a liquid state, wherein the first membrane layer comprises a proximal surface that adheres to the roof substrate over the lateral extent of the roof substrate, wherein the first membrane layer has a thickness that is generally uniform over the lateral extent of the roof substrate, wherein the first membrane layer comprises polyurea, and wherein the first membrane layer includes a plurality of cavity regions that are devoid of polyurea within an interior of the first membrane layer;
- and
- a second membrane layer comprising a plural component polymer applied as a liquid to the first membrane layer, wherein the second membrane layer adheres, upon solidification of the plural component polymer, to the distal surface of the first membrane layer.
