Anti-hail roofing system
View Patent ↗A section of a roof covering system, such as a shingle, having a flat base with planar top surface; and a plurality of fins disposed on the planar top surface at an essentially orthogonal angle to the planar top surfaces, forming a plurality of valleys between the fins, thereby forming a plurality of protrusions and recesses to damage, disintegrate and redirect hailstones which are incident upon the portion of the roof covering system.
1. A section of a roof covering system comprising:
a base portion having a substantially planar top surface; and
a plurality of fins disposed on the planar top surface at an essentially orthogonal angle to the planar top surfaces, the fins having a first height, wherein each fin has a rigid-material top shape configured to destruct, or redirect, or both destruct and redirect hailstones;
wherein the plurality of fins form a plurality of valleys therebetween, the valleys having a first width, thereby forming a plurality of protrusions and recesses configured to damage, disintegrate and redirect hailstones which are incident upon the portion of the roof covering system.
2. The section of a roof covering system as set forth in claim 1 wherein the base portion is provided with a nail zone free of the plurality of fins.
3. The section of a roof covering system as set forth in claim 2 wherein each of the plurality of fins comprises an upper edge shape adjacent to the nail zone, and wherein the fin upper edges are formed to capture a lower edge of a next-course section of roof covering to prevent wind lift.
4. The section of a roof covering system as set forth in claim 1 wherein the first height of the fins corresponds to a pre-determined maximum hailstone size.
5. The section of a roof covering system as set forth in claim 4 wherein the pre-determined maximum hailstone size is determined according to a geographical historical hailstone range.
6. The section of a roof covering system as set forth in claim 1 wherein the first width between the fins corresponds to a pre-determined maximum hailstone size.
7. The section of a roof covering system as set forth in claim 6 wherein the pre-determined maximum hailstone size is determined according to a geographical historical hailstone range.
8. The section of a roof covering system as set forth in claim 1 wherein the plurality of fins comprise two or more different heights.
9. The section of a roof covering system as set forth in claim 1 the plurality of fins.
10. The section of a roof covering system as set forth in claim 1 wherein the plurality of fins comprise a top edge of each fin, and where each top edge is provided with a contour for enhancing destruction and/or redirecting of incident hailstones.
