5. The ventilation system component of claim 4 , wherein the rubber base material is a fire retardant.

6. The ventilation system component of claim 1 , wherein the elongated strip of air-permeable compressible nonwoven material is shaped as a coil for packaging.

7. The ventilation system component of claim 6 , further comprising:

an elongated paper strip in contact with the adhesive, wherein the elongated paper strip prevents the adhesive from adhering to an adjacent surface of the elongated strip of air-permeable compressible nonwoven material when the elongated strip of air-permeable compressible material is rolled into a coil for packaging.

8. The ventilation system component of claim 1 , wherein the plurality of fibers comprises polyester fibers and the polyester fibers are moisture resistant.

9. The ventilation system component of claim 1 , wherein the elongated strip of air-permeable compressible nonwoven material is a single-baffled-layer coated with a phenolic resin.

10. The ventilation system component of claim 1 , wherein the elongated strip of air-permeable compressible nonwoven material measures 10 feet by 3 inches by 1.5 inches.

11. A method of installing a ventilation system component, comprising:

applying an elongated strip of compressible air permeable nonwoven material to a major roof panel, the elongated strip of nonwoven material having a first side opposite a second side, each side having a substantially continuous planar surface and the strip having a substantially constant cross-section of the material from a top of the strip downward when the strip is not in use and one of the first side or the second side conforming to and in substantially continuous engagement with one or more irregularities on the surface of the major roof panel without having dedicated segments to engage the irregularities and the other of the first side or the second side in substantially continuous engagement with a minor roof panel when the strip is in use; and

attaching the minor roof panel to the major roof panel, wherein a portion of the minor roof panel is in contact with the elongated strip of nonwoven material.

12. The method of claim 11 , wherein applying the elongated strip of nonwoven material includes applying the elongated strip of nonwoven material at a location on the major roof panel that is slightly up slope from an edge of a minor roof panel when the minor roof panel is attached to the major roof panel.

13. The method of claim 11 , wherein the minor roof panel is a ridge cap, the method further comprising:

attaching the ridge cap to the major roof panel and a second major roof panel that is adjacent to the major roof panel.

14. The method of claim 11 , wherein the minor roof panel is a wall-cap, the method further comprising:

attaching the wall-cap to the major roof panel at a location on the major roof panel that is adjacent to a wall.

15. A method of installing a ventilation system component, comprising:

applying a first elongated strip of compressible air permeable nonwoven material to a minor roof panel; and

attaching the minor roof panel to a major roof panel, wherein a portion of the major roof panel is in contact with the first elongated strip, wherein the first elongated strip has a first side opposite a second side, each side having a substantially continuous planar surface and the strip having a substantially constant cross-section of the material from a top of the strip downward when the strip is not in use and one of the first side or the second side substantially conforms to and is in substantially continuous contact with one or more irregularities on the surface of the major roof panel without having dedicated segments to engage the irregularities and the other of the first side or the second side is in substantially continuous contact with the minor roof panel when the strip is in use.

16. The method of claim 15 , wherein the minor roof panel is a ridge cap, the method further comprising:

inverting the ridge cap;

applying the first elongated strip adjacent to a first edge of the ridge cap;

applying a second elongated strip of compressible, air permeable nonwoven material adjacent to a second edge of the ridge cap, said strip having a first side opposite a second side, each side having a substantially continuous planar surface and the strip having a substantially constant cross-section of the material from a top of the strip downward when the strip is not in use and one of the first side or the second side being conformable to and in substantially continuous contact with a second major roof panel and the other of the first side and the second side in substantially continuous contact with the ridge cap when the strip is in use; and

attaching the ridge cap to the major roof panel and to the second major roof panel that is adjacent to the major roof panel.

17. The method of claim 15 , wherein the minor roof panel is a wall-cap, the method further comprising:

inverting the wall-cap;

applying the first elongated strip adjacent to a first edge of the wall cap; and

attaching the wall-cap to the major roof panel at a location on the major roof panel that is adjacent to a wall.

18. The method of claim 15 , wherein the first elongated strip is applied to the minor roof panel adjacent to an edge of the minor roof panel, the edge of the minor roof panel being longer than a length of the first elongated strip, the method further comprising:

applying a second elongated strip of compressible air permeable nonwoven material to the minor roof panel adjacent to the edge of the minor roof panel, including butt-fitting the second elongated strip of nonwoven material to the first elongated strip, said strip having a first side opposite a second side, each side having a substantially continuous planar surface and the strip having a substantially constant cross-section of the material from a top of the strip downward when the strip is not in use and one of the first side or the second side being conformable to and in substantially continuous contact with the major roof panel and the other of the first side and the second side in substantially continuous contact with the minor roof panel when the strip is in use.

19. The method of claim 15 , wherein the first elongated strip is applied to the minor roof panel adjacent to an edge of the minor roof panel, the edge of the minor roof panel being shorter than a length of the first elongated strip, the method further comprising:

cutting the first elongated strip such that its length corresponds to a length of the edge of the minor roof panel.
