Ridge cap with asphaltic foam materials
A ridge cap includes a lower surface adapted to be placed in contact with a roof of a building, a weather protective upper surface, and first and second side sections connected to each other. The first side section is disposed at one side of a longitudinal axis and the second side section is disposed at the other side of the longitudinal axis. The ridge cap further includes an elastomeric strip and a metal strip. The elastomeric strip extends along the longitudinal axis and connects the first side section and the second side section to be of unitary construction with the first and second side sections. The metal strip backing extends along the longitudinal axis and supports the elastomeric strip.
1. A method of making a ridge cap with a first width, the method comprising:
providing a conveyor belt;
applying a granule layer to said conveyor belt;
placing an elastomeric strip with a second width over the granule layer;
placing a metal strip with a third width over the elastomeric strip, the third width being smaller than the first width and the second width;
providing a reaction mixture comprising an asphalt and a mold over the conveyer belt;
subjecting the reaction mixture to a reaction condition to form an asphaltic foam in the mold; and
curing the asphaltic foam, thereby forming a ridge cap.
2. The method of claim 1 , wherein the metal strip is attached to the elastomeric strip.
3. The method of claim 1 , further comprising placing a net over the elastomeric strip.
4. The method of claim 3 , wherein the net and the metal strip are bonded to each other before being placed over the elastomeric strip.
5. The method of claim 1 , wherein the metal strip is disposed in a channel formed along a bending axis of the ridge cap.
6. The method of claim 5 , wherein the channel is formed on the side of the ridge cap that is configured to contact a roof.
7. The method of claim 1 , wherein subjecting the reaction mixture comprises:
forming first and second side sections of the asphalt foam connected to each other by the elastomeric strip, wherein the first side section is disposed at one side of a longitudinal axis and the second side section is disposed at the other side of the longitudinal axis,
wherein the elastomeric strip and the metal strip together form a hinge about which the first and second side sections are pivotable with respect to each other.
8. The method of claim 7 , wherein the elastomeric strip and the metal strip connect the first and second side sections.
9. The method of claim 7 , wherein the metal strip is attached to the elastomeric strip.
10. The method of claim 1 , wherein the metal strip is coupled to the elastomeric strip with an intermediate layer therebetween.
11. The method of claim 1 , wherein the metal strip is of one selected from the group consisting of aluminum, brass, copper, tin and an alloy comprising at least one of aluminum, brass, copper and tin.
12. The method of claim 1 , wherein the elastomeric strip comprises a strip of modified asphalt.
13. The method of claim 1 , wherein the asphaltic foam is more rigid than the elastomeric strip.
14. The method of claim 1 , wherein the asphalt foam contacts and is coupled to the elastomeric strip.
