Abstract

Claims (43)

1. A roofing system comprising:

a roofing substrate; and

at least two roofing membranes,

wherein the at least two roofing membranes are located on the roofing substrate;

wherein the at least two roofing membranes are partially overlapping, so as to form an overlapping portion;

wherein each of the at least two roofing membranes independently comprises:

30% to 90% by weight of a crosslinked polymer,

wherein the crosslinked polymer comprises at least one of a polysiloxane, a silyl-terminated polymer, or any combination thereof;

1% to 30% by weight of a silicone fluid; and

1% to 15% by weight of a boron-containing compound,

wherein the boron-containing compound comprises at least one of a boric acid, a boronic acid, a pyroboric acid, a boronate ester, a borate ester, a borosiloxane oligomer, a borosiloxane polymer, a boric anhydride, a boride, or any combination thereof.

2. The roofing system of claim 1 , wherein the roofing substrate comprises at least one of a roof deck, an underlayment, or any combination thereof.

3. The roofing system of claim 1 , wherein the at least two roofing membranes are directly adhered to each other in the overlapping portion.

4. The roofing system of claim 1 , wherein an adhesive is not located between the at least two roofing membranes in the overlapping portion.

5. The roofing system of claim 1 , wherein the at least two roofing membranes are not heat welded together in the overlapping portion.

6. The roofing system of claim 1 , wherein at least one of the at least two roofing membranes is a liquid applied roofing membrane.

7. The roofing system of claim 1 , wherein at least one of the at least two roofing membranes is a roofing accessory.

8. A roofing system comprising:

a roofing substrate; and

at least three roofing membranes,

wherein the at least three roofing membranes are located on the roofing substrate;

wherein the at least three roofing membranes are partially overlapping, so as to form an overlapping portion;

wherein each of the at least three roofing membranes independently comprises:

30% to 90% by weight of a crosslinked polymer,

wherein the crosslinked polymer comprises at least one of a polysiloxane, a silyl-terminated polymer, or any combination thereof;

1% to 30% by weight of a silicone fluid; and

1% to 15% by weight of a boron-containing compound,

wherein the boron-containing compound comprises at least one of a boric acid, a boronic acid, a pyroboric acid, a boronate ester, a borate ester, a borosiloxane oligomer, a borosiloxane polymer, a boric anhydride, a boride, or any combination thereof.

9. The roofing system of claim 8 , wherein the roofing substrate comprises at least one of a roof deck, an underlayment, or any combination thereof.

10. The roofing system of claim 8 , wherein the at least three roofing membranes are directly adhered to each other in the overlapping portion.

11. The roofing system of claim 8 , wherein an adhesive is not located between the at least three roofing membranes in the overlapping portion.

12. The roofing system of claim 8 , wherein the at least three roofing membranes are not heat welded to each other in the overlapping portion.

13. A method of installation comprising:

obtaining at least two roofing membranes,

wherein each of the at least two roofing membranes independently comprises:

30% to 90% by weight of a crosslinked polymer,

wherein the crosslinked polymer comprises at least one of a polysiloxane, a silyl-terminated polymer, or any combination thereof;

1% to 30% by weight of a silicone fluid; and

1% to 15% by weight of a boron-containing compound,

wherein the boron-containing compound comprises at least one of a boric acid, a boronic acid, a pyroboric acid, a boronate ester, a borate ester, a borosiloxane oligomer, a borosiloxane polymer, a boric anhydride, a boride, or any combination thereof;

installing the at least two roofing membranes on a roofing substrate, such that the at least two roofing membranes are partially overlapping in an overlapping portion; and

adhering the at least two roofing membranes to each other in the overlapping portion.

14. The method of claim 13 , wherein the adhering does not comprise heat welding the at least two roofing membranes to each other; wherein the adhering does not comprise adhering the at least two roofing membranes to each other with an adhesive.
