Description

BACKGROUND

Field of the Disclosure

The present disclosure is directed generally to roofing materials and more particularly to synthetic roofing tiles.

Description of the Related Art

It is known in the shingle art that shingles that are applied to a roof are generally applied in courses, running up the slope of a roof, toward the apex or ridge of the roof. On a hip type roof, the shingles are similarly applied up the sloped surfaces toward the ridge of the roof and the singles meet at interfaces along hips and valleys.

In applying shingles to the different sloped surfaces of a roof, wherein those sloped surfaces meet at an apex and at hips, the various courses of shingles on each side of the apex are increasingly disposed up each slope, between the hips, until the apex or ridge of the roof is reached. At that point, it is desirable to provide a shingle that is a unitary structure that overlies a portion of each sloped surface of the roof along the hips and along the apex of the roof.

Synthetic ridge tiles are known in the art. These tiles can also be used along the hips of a hip type roof. However, these tiles are not suited for use as starter tiles for the hips of a hip type roof.

Accordingly, the roofing industry continues to need improvements in synthetic roofing tiles, particularly to synthetic roofing tiles that can be used as starter tiles for a hip of a hip type roof.

DETAILED DESCRIPTION

The following description is directed to synthetic roofing tiles, and particularly, to synthetic starter tiles configured to fit over angled roof interfaces, e.g., hip interfaces, valley interfaces, and ridge interfaces. The synthetic starter tiles can include exposed edges that are configured to approximate the shape of the outer perimeter of a roof on which the synthetic starter tiles are installed and the appearance of a natural stone tile that has been chipped during a shaping process. A typical synthetic ridge tile can be used as a starter tile for a hip, but a portion of the exposed edge will overhang the perimeter of the roof along the edge of the roof and can be unsightly or even cause rainwater to flow off of the roof in an odd manner and not enter a gutter installed at the edge of the roof. A synthetic ridge tile may be cut onsite by an installer to approximate the perimeter of the edge of the roof. However, such a cut tile may have an unsightly jagged edge in which the underside ribs of the tile are exposed. Further, such a cut tile may allow rainwater to blow, or wick, under the tile which can lead to damage to the underlying roof substrate.

Referring initially to FIG. 1 through FIG. 7, a first embodiment of a synthetic starter tile for an angled roof interface is illustrated and is generally designated 100. The synthetic starter tile 100 can include a generally non-planar body 102 having an overlap portion 104 and an exposed portion 106. The overlap portion 104 can include an overlap edge 108 and the exposed portion 106 can include an exposed edge 110.

In a particular aspect, the overlap portion 104 can include a length, L_OP, and the exposed portion 106 can also include a length, L_EP, and L_OP can be ≥L_EP. In particular, L_OP can be ≥1.25 L_EP, such as L_OP≥1.5 L_EP, L_OP≥1.75 L_EP, L_OP≥2.0 L_EP, or L_OP≥2.25 L_EP. Further, L_OP can be ≤3.0 L_EP, such as L_OP≤2.75 L_EP, or L_OP≤2.5 L_EP. In another aspect, L_OP can be within a range between and including any of the maximum and minimum values of L_OP described herein.

Further, the overlap portion 140, 142 of each side 132, 134 can include at least one anchor point 148 through which a fastener can be installed. As illustrated, the anchor points 148 may be located within the overlap portion 140, 142 of each side 132, 134 nearer to the overlap edge 108. In another aspect, described below, the anchor points 148 may be located within the overlap portion 140, 142 of each side 132, 134 nearer to the exposed portion

FIG. 8 also indicates that the body 802 of the synthetic starter tile 800 can include at least one anchor point 830 and the anchor point 830 can be located within the overlap portion 804 near the exposed portion 806. Accordingly, in certain aspects that utilize another tile, or a portion of another tile, beneath the synthetic starter tile 800, a fastener can be installed through the synthetic starter tile 800 and the other tile placed underneath the synthetic starter tile 800.

FIG. 9 shows that the underneath of the body 802 can include a solid perimeter edge portion 830 extending along the entirety of the exposed edge 810. FIG. 10 and FIG. 11 indicate that the body 802 can be thicker through the ridge than at the lateral edges 812, 814.

With the configuration described herein, the synthetic starter tile for an angled roof interface provides a starter tile that can be used, for example, on a hip interface or a valley interface. The starter tile includes an exposed portion having a textured surface finish along an exposed edge that approximates the appearance of a chipped slate tile. Further, the synthetic starter tile includes a solid perimeter edge portion along the bottom of the exposed edge that can effectively seal the underneath of the starter tile and prevent rain from wicking or blowing under the starter tile. Moreover, the exposed edge of the synthetic starter tile includes two angle portions that each form acute compound angles with respect to a longitudinal axis. After installation, the angled portions of the exposed edge can closely approximate the perimeter shape of the underlying roof structure on which the synthetic starter tile is disposed. As such, the synthetic starter tile for an angled roof interface can properly protect the underlying roof structure and properly direct rainwater from the roof into a gutter system. Moreover, while the synthetic starter tile is shown with a cross-section have a downward facing V-shape, it can be understood that the synthetic starter tile can be formed with an upward facing V-shape to fit into a valley interface instead of onto a hip interface. In such a case, the angle portions of the exposed edge can be angled to approximate the shape of the perimeter of the roof at the valley, e.g., in a direction that is generally opposite to the angled portions described herein.

A skilled artisan can recognize that there may be others applications that can utilize a synthetic starter tile for an angled roof interface having one or more of the characteristics described herein.
