Adhesive projection points for roofing elements

Abstract

A roofing element such as a concrete tile is provided that includes a body portion extending between a head end and a nose end. The body portion includes a lower surface, an upper surface, and a protrusion that is disposed substantially adjacent the nose end and extends downwardly from the lower surface. The protrusion is disposed on the lower surface such that when a nose end of a second roofing element is installed vertically above a head end of a first roofing element and overlapping by at least 3 inches, the protrusion of the second roofing element is positioned substantially above an aperture defined in the head end of the first roofing element. The protrusion reduces a distance between the aperture of the first roofing element and the nose end of the second roofing element, which increases the likelihood that the adhesive will securely join the first roofing element with the second roofing element.

Description

BACKGROUND[0001]1. Field of the Disclosure[0002]The disclosure relates to an improvement in the design of roofing elements, and more particularly to roof tiles having a projecting structure on the underside of a tile that provides an improved connection between tiles when secured together with adhesives.[0003]2. Related Art[0004]In the installation of concrete roofing elements, such as field tiles and trim tiles, a nose end of a second course tile is positioned to overlap a head end of a first course tile to cover one or more apertures in the head end of the first course tile. The apertures in the head end of the tiles receive fasteners such as nails or screws, for securing the tiles to the roof surface, and the overlap of the nose end of the second course tile over the head end of the first course tile discourages rain and debris from leaking through the apertures. For example, when installing field tiles, a second field tile is installed as part of a second horizontal course of fi...
