Abstract

Some embodiments of the present disclosure relate to a roofing system. In some embodiments, the roofing system comprises at least one steep slope roof substrate having a first region. In some embodiments, the first region comprises a plurality of shingles. In some embodiments, each of the plurality of shingles comprises at least one antimicrobial agent. In some embodiments, the at least one steep slope roof substrate also comprises a second region. In some embodiments, the second region comprises an antimicrobial scavenger layer that is configured to receive runoff from the first region of the steep slope roof substrate. In some embodiments, the runoff comprises an initial concentration of at least one antimicrobial agent and water. In some embodiments, the antimicrobial scavenger layer is configured to capture the at least one antimicrobial agent so as to reduce the initial concentration of the at least one antimicrobial agent in the runoff.

Claims (48)

1. A roofing system comprising:

a steep slope roof substrate;

a plurality of shingles above the steep slope roof substrate;

a treatment component above the steep slope roof substrate,

wherein the treatment component is downslope of the plurality of shingles and configured to receive runoff from the plurality of shingles,

wherein the runoff comprises:

water, and

at least one other component;

wherein the treatment component comprises a first layer and a second layer,

wherein the first layer is configured to allow the runoff to flow through the first layer to the second layer,

wherein the second layer comprises a treatment material configured to reduce a concentration of the at least one other component in the runoff; and

a water barrier material above the steep slope roof substrate,

wherein the treatment component is above the water barrier material.

2. The roofing system of claim 1 , wherein the at least one other component comprises at least one of a metal or a metal ion.

3. The roofing system of claim 1 , wherein the at least one other component comprises at least one of copper or a copper ion.

4. The roofing system of claim 1 , wherein the at least one other component comprises at least one of an algaecide, biocide, or fungicide.

5. The roofing system of claim 1 , wherein the treatment material is configured to capture the at least one other component.

6. The roofing system of claim 1 , wherein the plurality of shingles comprises at least a first shingle,

wherein the first shingle comprises the at least one other component.

7. The roofing system of claim 6 , wherein the first shingle comprises:

a polymer matrix,

wherein the at least one other component is within the polymer matrix.

8. The roofing system of claim 1 , wherein the treatment material is configured to capture the at least one other component via ion exchange, osmosis, filtration, absorption, chelation, or chemical binding.

9. The roofing system of claim 1 , wherein the treatment material comprises activated carbon.

10. The roofing system of claim 1 , wherein at least one shingle of the plurality of shingles is above the water barrier material.

11. A roofing system comprising:

a steep slope roof substrate;

a plurality of shingles above the steep slope roof substrate;

a treatment component above the steep slope roof substrate,

wherein the treatment component is downslope of the plurality of shingles and configured to receive runoff from the plurality of shingles,

wherein the runoff comprises:

water, and

at least one other component;

wherein the treatment component comprises a first layer and a second layer,

wherein the first layer is configured to allow the runoff to flow through a plurality of openings in the first layer, to the second layer,

wherein the second layer comprises a treatment material configured to reduce a concentration of the at least one other component in the runoff.

12. The roofing system of claim 11 , wherein the at least one other component comprises at least one of a metal or a metal ion.

13. The roofing system of claim 11 , wherein the at least one other component comprises at least one of copper or a copper ion.

14. The roofing system of claim 11 , wherein the at least one other component comprises at least one of an algaecide, biocide, or fungicide.

15. The roofing system of claim 11 , wherein the treatment material is configured to capture the at least one other component.

16. The roofing system of claim 11 , wherein the plurality of shingles comprises at least a first shingle,

wherein the first shingle comprises the at least one other component.

17. The roofing system of claim 16 , wherein the first shingle comprises:

a polymer matrix,

wherein the at least one other component is within the polymer matrix.

18. The roofing system of claim 11 , wherein the treatment material is configured to capture the at least one other component via ion exchange, osmosis, filtration, absorption, chelation, or chemical binding.

19. The roofing system of claim 11 , wherein the treatment material comprises activated carbon.

20. The roofing system of claim 11 , wherein at least one shingle of the plurality of shingles is above the water barrier material.
