Abstract

Some embodiments of the present disclosure relate to methods and roofing systems including a hybrid layered structure. In some embodiments, the hybrid layered layer structure, method, and system are used for waterproofing at least one steep slope roof substrate. In some embodiments, the at least one steep slope roof substrate at least one protruding member protruding from the at least one steep slope roof substrate. In some embodiments, the hybrid layered structure comprises a first coating layer, a roofing membrane, and a second coating layer.

First claim

The invention claimed is:

1. A method comprising:
obtaining a roofing membrane;
obtaining a liquid applied roofing formulation;
applying the liquid applied roofing formulation to
(a) at least one flashing area;
(b) a portion of at least one protruding member; and
(c) a portion of at least one steep slope roof substrate
so as to form a first coating layer,
wherein the at least one protruding member protrudes from the at least one steep slope roof substrate; and
wherein the at least one flashing area comprises an interface between the at least one steep slope roof substrate and the at least one protruding member; and

covering the first coating layer with a roofing membrane, so as to form a hybrid layered structure,
wherein the hybrid layered structure comprises:
the first coating layer; and
the roofing membrane; and

wherein the at least one steep slope roof substrate does not include any flashing other than the hybrid layered structure.

2. The method of claim 1 ,
wherein the at least one flashing area comprises:
a first flashing area;
and

a second flashing are;

wherein the at least one protruding member comprises:
a first protruding member, and
a second protruding member; and

wherein the method further comprises applying the liquid applied roofing formulation to:
(a) the second flashing area
(b) the second protruding member; and
(c) the portion of at least one steep slope roof substrate
so as to form a second coating layer; and

wherein the hybrid layered structure comprises:
the first coating layer;
the roofing membrane; and
the second coating layer.

3. The method of claim 1 , wherein the liquid applied roofing formulation comprises at least one resin.

4. The method of claim 3 , wherein the at least one resin is chosen from polysiloxane, polyurea, polyurethane, silane modified ether, silane modified ester, silane modified polyurethane, silane modified polyurea, epoxy resin, acrylic resin, polyacrylic resin, any precursor thereof, or any combination thereof.

5. The method of claim 3 , wherein the at least one resin is present in an amount ranging from 20% to 100% based on a total weight of the liquid applied roofing formulation.

6. The method of claim 1 , wherein the liquid applied roofing formulation has a viscosity ranging from 100 cP to 10 million cP at 25° C. measured using a Brookfield viscometer at 20 rpm.

7. The method of claim 2 , wherein the roofing membrane is disposed over the second coating layer.

8. A roofing system comprising:
at least one steep slope roof substrate,
at least one protruding member,
wherein the at least one protruding member protrudes from the at least one steep slope roof substrate;

at least one flashing area,
wherein the at least one flashing area comprises an interface between the at least one steep slope roof substrate and the at least one protruding member; and

a hybrid layered structure, wherein the hybrid layered structure comprises:
a first coating layer, wherein the first coating layer comprises
a liquid applied roofing formulation disposed over the at least one flashing area, a portion of the at least one protruding member, and a portion of the at least one steep slope roof substrate; and

a roofing membrane,
wherein the roofing membrane is disposed over the first coating layer wherein the at least one steep slope roof substrate does not include any flashing other than the hybrid layered structure.

9. The roofing system of claim 8 ,
wherein the at least one flashing area comprises:
a first flashing area;
and
a second flashing area;
and

wherein the at least one protruding member comprises:
a first protruding member, and
a second protruding member; and

wherein the roofing system further comprises a second coating layer, wherein the second coating layer is disposed over the second flashing area, a portion of the second flashing area, and the portion of the at least one steep slope roof substrate, and wherein the hybrid layered structure comprises:
the first coating layer;
the roofing membrane; and
the second coating layer.

10. The roofing system of claim 8 , wherein the roofing membrane is disposed over the second coating layer.

11. A method comprising:
obtaining a roofing membrane;
obtaining a liquid applied roofing formulation;
applying the liquid applied roofing formulation to
(a) at least one flashing area;
(b) a portion of at least one protruding member; and
(c) a portion of at least one steep slope roof substrate
so as to form a first coating layer,
wherein the at least one protruding member protrudes from the at least one steep slope roof substrate; and
wherein the at least one flashing area comprises an interface between the at least one steep slope roof substrate and the at least one protruding member; and

covering the first coating layer with a roofing membrane, so as to form a coated roofing membrane;
applying a second coating layer to the coated roofing membrane so as to form a hybrid layered structure,
wherein the hybrid layered structure comprises:
the first coating layer;
the second coating layer; and
the roofing membrane.
