Abstract

Silicone roofing materials are provided. A roofing material comprises at least one of a plurality of particles, a silicone coating, a substrate, an adhesive layer, a release liner, or any combination thereof. The substrate is located between the silicone coating and the adhesive layer. The adhesive layer is located between the substrate and the release liner. The release liner covers at least a portion of the adhesive layer. The plurality of particles covers at least a portion of a surface of the silicone coating. Each of the plurality of particles has a surface. When the roofing material is installed on a roofing substrate, at least a portion of the surface of the plurality of particles is exposed to an environment. Related systems and related methods are also provided.

First claim

What is claimed is:

wherein at least a portion of the second surface of the silicone roofing membrane contacts at least a portion of the first surface of the silicone roofing membrane;
wherein at least a portion of the second surface of the silicone roofing membrane is an outer surface of the roll;

wherein the silicone roofing membrane comprises:
a plurality of particles;
a silicone coating;
a substrate;
an adhesive layer; and
a release liner;
wherein the substrate comprises at least one of a mesh, a fabric, a scrim, a woven, a non-woven, or any combination thereof;
wherein the substrate is located between the silicone coating and the adhesive layer,
 wherein the silicone coating covers the entirety of a surface of the substrate;
 wherein the silicone coating directly contacts the surface of the substrate;
wherein the adhesive layer is located between the substrate and the release liner;
wherein the release liner covers at least a portion of the adhesive layer;
wherein the plurality of particles covers at least a portion of a surface of the silicone coating;
 wherein each of the plurality of particles has a surface,
 wherein, when the silicone roofing membrane is installed on a roofing substrate, at least a portion of the surface of the plurality of particles is exposed to an environment;
wherein the first surface of the silicone roofing membrane is the surface of the silicone coating;
wherein the second surface of the silicone roofing membrane is a surface of the release liner.

2 . The roll of claim 1 , wherein, when the silicone roofing membrane is installed on a roofing substrate, at least a portion of the surface of the silicone coating is exposed to the environment.

3 . The roll of claim 1 , wherein, when the silicone roofing membrane is installed on a roofing substrate,
1% to 99% of the surface of the plurality of particles is exposed to the environment; and 1% to 99% of the surface of the silicone coating is exposed to the environment.

4 . The roll of claim 1 , wherein the plurality of particles directly contacts the surface of the silicone coating.

5 . The roll of claim 1 , wherein the plurality of particles is embedded in the surface of the silicone coating.

6 . The roll of claim 1 , wherein the plurality of particles covers 50% to 99% of the surface of the silicone coating.

7 . The roll of claim 1 , wherein the plurality of particles comprises at least one of a sand, a polymer fiber, a glass fiber, a glass bead, a recycled granule, a polymeric granule, a mineral granule, a water-soluble granule, a polymeric powder, or any combination thereof.

8 . The roll of claim 1 , wherein the silicone coating comprises at least one of a polysiloxane, a silyl-terminated polymer, or any combination thereof.

9 . A roofing system comprising:
a roofing substrate; and a silicone roofing membrane,
wherein the silicone roofing membrane is located on the roofing substrate;
wherein the silicone roofing membrane comprises:
a plurality of particles;
a silicone coating;
a substrate; and
an adhesive layer;
wherein the substrate comprises at least one of a mesh, a fabric, a scrim, a woven, a non-woven, or any combination thereof;
wherein the substrate is located between the silicone coating and the adhesive layer,
 wherein the silicone coating covers the entirety of a surface of the substrate;
 wherein the silicone coating directly contacts the surface of the substrate;
wherein the adhesive layer is located between the substrate and the roofing substrate;
wherein the adhesive layer adheres the silicone roofing membrane to the roofing substrate;
wherein the plurality of particles covers at least a portion of a surface of the silicone coating;
 wherein each of the plurality of particles has a surface,
 wherein at least a portion of the surface of the plurality of particles is exposed to an environment.

10 . The roofing system of claim 9 , wherein at least a portion of the surface of the silicone coating is exposed to the environment.

11 . The roofing system of claim 9 , wherein the plurality of particles directly contacts the surface of the silicone coating.

12 . The roofing system of claim 9 , wherein the plurality of particles is embedded in the surface of the silicone coating.

13 . The roofing system of claim 9 , wherein the plurality of particles comprises at least one of a sand, a polymer fiber, a glass fiber, a glass bead, a recycled granule, a polymeric granule, a mineral granule, a water-soluble granule, a polymeric powder, or any combination thereof.

14 . The roofing system of claim 9 , wherein the silicone coating comprises at least one of a polysiloxane, a silyl-terminated polymer, or any combination thereof.

15 . A method of installation comprising:
obtaining a roll of a silicone roofing membrane,
wherein the silicone roofing membrane has a first surface and a second surface opposite the first surface,
wherein at least a portion of the second surface of the silicone roofing membrane contacts at least a portion of the first surface of the silicone roofing membrane;
wherein at least a portion of the second surface of the silicone roofing membrane is an outer surface of the roll;

wherein the silicone roofing membrane comprises:
a plurality of particles;
a silicone coating;
a substrate;
an adhesive layer; and
a release liner;
wherein the substrate comprises at least one of a mesh, a fabric, a scrim, a woven, a non-woven, or any combination thereof;
wherein the substrate is located between the silicone coating and the adhesive layer,
 wherein the silicone coating covers the entirety of a surface of the substrate;
 wherein the silicone coating directly contacts the surface of the substrate;
wherein the adhesive layer is located between the substrate and the release liner;
wherein the release liner covers at least a portion of the adhesive layer;
wherein the plurality of particles covers at least a portion of a surface of the silicone coating;
 wherein each of the plurality of particles has a surface;
