DESCRIPTION OF THE PREFERRED EMBODIMENT

[0014] A ridge protection system 10 is shown in FIG. 1 that is attached to an existing roof 12. The existing roof 12 has a ridge vent 14, which is attached to the roof 12 along the peak 13. The peak 13 terminates at a gable end surface 15. The roof 12 has a shingled surface 16 that is sloped away from the peak 13. The ridge vent 14 overlays the peak 13 and has an upper surface 18 that is spaced from the shingled surface 16. The upper surface 18 is typically shingled similarly to the shingled surface 16. It is contemplated that the upper surface 18 is defined as the upper surface of the ridge vent 14 and there is a shingled surface over the top. The upper surface 18 terminates at lateral edges 20 and terminal edges 22. The ridge vent 14 has a perimeter edge defined by the lateral edges 20 and terminal edges 22. As shown in FIG. 2, the portions of the upper surface 18, particularly near the lateral edges 20, are parallel or nearly parallel to the shingled surface 16. The lateral edges 20 are spaced from the shingled surface 16 to provide an airgap 24 where air can flow to maintain desired attic environmental conditions. Ridge vents 14 are commonly made from plastics or other materials that simplify transportation and installation but may not be durable or impervious to pests, such as rodents, birds, or other invasive and destructive animal. It is common but not required that the roof 12, ridge vent 14, and nearby shingled surface is symmetrical about the peak 13. One side of the roof 12 is a first side and the other side of the roof 12 is a second side.

[0015] The system 10 affixes to the roof 12 as shown in the FIGS. 1-3. The system 10 has an edge barrier 30, formed from perforated or expanded durable material, such as metal. The durable material has some resilient properties but can be bent and formed. It is commonly coated to prevent or reduce corrosion. The perforations 29 allow air, moisture, and liquids to pass through but block items that are larger than the perforations. The system 10 is affixed to the roof 12 using self-sealing fasteners 32. The edge barrier 30 is formed from a single flat sheet with a lower lateral edge 34 and an upper lateral edge 36. The edge barrier 30 has terminal edges 31. A lower planar portion 38 is aligned with a lower plane 39 and extends between the lower lateral edge 34 and a lower bend 40. Located between the lower bend 40 and an upper bend 42 is an offset portion 44, which is aligned with an offset plane 45. Located between the upper bend 42 and the upper lateral edge 36 is an upper planar portion 46 located on an upper plane 47. The width of the upper planar portion 46 is larger than the lower planar portion 38. The larger width of the upper planar portion 46 allows the edge barrier 30 to be set away from the lateral edge 20 while still providing sufficient overlap to the upper surface 18.

[0016] When installed, the edge barrier 30, particularly the lower planar portion 38, is affixed to the roof 12 and aligned to be coplanar or mostly coplanar to the shingled surface 16. The offset portion 44 has a width defined by the distance between the lower bend 40 and the upper bend 42. The width of the offset portion 44 corresponds with a tangent distance 28 between the shingled surface 16 and one of the lateral edges 20 of the ridge vent 14. The tangent distance 28 is represented by the distance measured perpendicularly from the shingled surface 16, shown in FIG. 3. The width of the offset portion 44 may be greater than the tangent distance 28.

[0017] The edge barrier 30 is shown in an uninstalled state in FIG. 5. As uninstalled, the lower bend 40 is obliquely angled with respect to the offset portion 44 and the lower planar portion 38, and the upper bend 42 is obliquely angled with respect to the offset portion 44 and the upper planar portion 46. As shown in FIG. 4, the upper lateral edge 36 is closer to the lower plane 39 than the upper bend before installation. After installation, the upper lateral edge 36 is moved away from the lower plane 39 and provides biased contact to the upper surface 18. It is contemplated that the biased contact is on the underlying ridge vent 14 with the upper surface 18 covered by shingles. In this state the shingles on the ridge vent would overlay the upper planar portion 46. In the installed state, as shown in FIG. 9, the lower plane 39 is more parallel to the upper plane 47.

[0018] The system 10 includes end caps 50, 52, depending on the installation of the ridge vent 14. The flush end cap 50 is shown in FIG. 6 and the set-back end cap 52 is shown in FIG. 7. If the ridge vent terminal edge 22 is aligned with the gable end surface 15 of the roof 12, as shown in FIG. 1, the flush end cap 50 is used. If the ridge vent terminal edge 22 is located short of the gable end surface 15, set-back end cap 52 is used. Flush end cap 50 has a vertical portion 54 that meets an overlaying portion 56 at a bend 58. To match the pitch and peak of the roof 12 and ridge vent 14, the vertical portion 54 may be cut 51 and overlaid, shown in FIG. 6. The flush end cap 50 is commonly press-formed by the installer to conform the end cap 50 to the roof peak curvature. Press-forming involves the user pressing down on terminal ends of the end cap 50 to permanently bend it. A set-back end cap 52 is formed by taking a portion of the edge barrier 30 and forming it to match the peak 13 of the roof 12. The offset portion 44 is also referred to as the vertical portion for the set-back end cap 52. The upper planar portion 46 of the set-back end cap 52 is also referred to as an overlaying portion. If the roof 12 is steep, the installer may add cuts 53 through the lower planar portion 38 and offset portion 44. The set-back end cap 52 is commonly press-formed by the installer to conform the end cap 52 to the roof peak curvature. This allows the upper planar portion 46 to match the curvature of the upper surface 18. As with the edge barrier 30, the lower planar portion 38 is affixed to the shingled surface 16 with fasteners 32. The installation with the terminal edge 22 of the ridge vent 14 being set back from the gable end surface 15 is shown in FIG. 2.

[0019] The end caps 50, 52 are shown as a separate component, but it is contemplated that the edge barrier 30 is curved around to form the end cap or a portion of the end cap. It is contemplated that the edge barrier 30 is bent to form the end cap portion, and then curved again to continue along the opposite side of the ridge vent 14. In this event, the top surface 46 would be cut to allow the edge barrier 30 to curve around.

[0020] An optional top barrier 60 may be installed that overlays the upper surface 18 of the ridge vent 14. The top barrier 60 has a perimeter made up of opposing lateral edges 62 and end edges 64. In the uninstalled state, the top barrier 60 may be curved or flat. As installed, it closely conforms to the upper surface 18. In FIG. 3, a section view of an example installation is shown with the top barrier 60 shown. FIGS. 3 and 3a are separated by a break line 70, with the left side of the break line 70 showing the top barrier 60 installed (FIG. 3). The break line 70 is imaginary and only to demonstrate alternative installations in a single view. The right side of the break line 70 shows the installation of the system 10 without the optional top barrier 60 (FIG. 3a). In an installation a top barrier 60, the lateral edges 62 would be adjacent the lateral edges 20 of the ridge vent 14. If the optional top barrier 60 is used, when the edge barrier 30 is installed, the upper lateral edge 36 is in biased contact with the optional top barrier 60. The perimeter of the top barrier 60 is retained by the edge barriers 30 and end caps 50, 52.

[0021] As installed, the upper lateral edge 36 of the edge barrier 30 applies a biasing force to the upper surface 18 of the ridge vent 14. Further, the additional width of the upper planar portion 46 allows the edge barrier 30 to be installed with the upper bend 42 spaced from the lateral edge 20, shown in FIG. 3. This allows airflow through the part of the upper planar portion 46 in addition to the offset portion 44. If the optional top barrier 60 is installed (as is shown on the left side of FIG. 3, the upper lateral edge 36 of the edge barrier 30 applies biasing force to portions of the top barrier 60 to retain it and maintain contact with the upper surface 18.

[0022] To install the system 10, any damaged or missing components on the roof 12 or ridge vent 14 are repaired or replaced. Optionally, the top barrier 60 is installed with lateral edges 62 being located next to lateral edges 20 of the ridge vent 14. The top barrier 60 will overlay the entire upper surface 18 and extend to the terminal edges 22. Next, the edge barriers 30 are positioned with the terminal edge 31 aligned with the terminal edge 22 of the existing ridge vent 14. The lateral edge 20 located between the upper bend 42 and upper lateral edge 36. Fasteners 32 are driven through the lower planar portion 38, through the shingled surface 16 and into the roof structure, such as roof decking 17. The edge barriers 30 are installed with terminal edges 31 aligned with terminal edges 22 of the ridge vent 14. Multiple edge barriers 30 may be installed to cover the entire lateral edge 20 of the ridge vent 14. Edge barriers 30 are installed over both lateral edges 20, as shown in the FIGS. 1-3. Once all of the edge barriers 30 are installed, the installer will choose which end cap 50, 52 is more appropriate. The flush end cap 50 is selected if the terminal edge 22 is aligned with the gable end surface 15, as is shown in FIG. 1. The installer will trim the length and add cuts 51 through the vertical portion 54 to bend or curve the overlaying portion to conform to the upper surface 18. The length is chosen to align terminal ends of the flush end cap 50 are aligned or nearly aligned with the lateral edges 20 of the ridge vent 14. The installer then uses fasteners 32 through the gable end surface 15. For the set-back end cap 52, the installer may add cuts 53 through the lower planar portion 38 and offset portion 44 to conform the upper planar portion 46 to match the curvature or profile of the upper surface 18. As with the edge barriers 30, fasteners 32 are driven through the lower planar portion 38 through the shingled surface 16 and into the roof decking 17. Ends of the end caps 50, 52 may be bent to be interlocked with the terminal ends of the edge barriers 30. Once installed, the system 10 will overlay the entire perimeter of the ridge vent 14.
