Description

2340145 DRY VERGE SYSTEMS The present invention relates to improved dry

verge trims which protect the roof verge on a building, particularly on a gable end, from wind driven rain penetration and can be retrofitted to a variety of roof types or fitted during construction of new buildings.

lt is known traditionally to fill the tile batten void between the verge undercloaking and the tiles with cement based mortar, This method has a number of known drawbacks including: the method being time consuming and labour intensive; the mortar adhesion to the verge tiles being poor and therefore high winds may create sufficient suction to displace the verge tiles; and the mortar being prone to cracking which reduces its performance and is unsightly.

Alternatively plastics dry fix verge systems exist. However these known systems have a number of drawbacks:

1. Most must be fitted to the tile battens before the laying of tiles on new -roofs or by first removing tiles from existing roofs to reveal the battens.

2. Those few suitable for fitting to existing roofs without removing tiles have fitting screws exposed which are unsightly and prone to rust.

3. The known systems are limited to a particular type or thickness of roof tile.

4. The known systems have no provision to conceal wiring.

2 The object of the present invention is to provide a dry verge system which can be retrofitted to an existing roof verge to provide the weatherproofing and tile security benefits of a dry verge system without having to remove the existing tiles at the verge or the existing mortar in the tile batten void.

The system is to be equally suited for use in new buildings during construction.

The present invention also intends to provide a dry verge system which is suitable for a number of different types of roof tile.

Accordingly the present invention provides a dry verge system for use between roof tiles or slates of a building and an adjacent portion of the building comprising a component having connected first and a second portions wherein the first portion is adapted to be secured to the adjacent portion of the building and the second portion comprises at least two sides of which a first side is adapted to extend across part of top faces of the roof tiles or slates and a second side depends therefrom and the components create a joint between the tiles or slates and the building to prevent water penetration.

The first portion preferably comprises means for securing it to the portion of the building, for example holes through which screws can pass.

The first portion being secured to a portion of the building enables the 25 system to be installed on existing roofs rather than between wall and batten before the tiles or slates are laid.

Preferably the first portion is secured to an existing b arge board of the building. Alternatively it may be secured directly to the brickwork or to a spacer panel or fascia board or any other suitable portion of the building.

3 The position of the first portion may be adjusted to correspond with the depth of the tiles or slates and battens. This allows a variety of types of tiles or slates to be accommodated, Preferably the second portion further comprises a third side extending inwardly from the second side and meeting with the first portion, Most preferably the second portion is substantially C-shaped. The use of a C- shaped second portion means that any wind driven rain which passes between the first side and the tiles or slates gathers in the base of the C-shaped portion and can drain down the channel created by the third side of the second portion into the eaves gutter.

The first side of the second portion is preferably flexible and at rest is at an acute angle to the second side so that it exerts some pressure on the tiles or slates when in position in use substantially at right angles to the second side, which helps it to maintain its position.

In a first aspect of the present invention the first and second portions may be connected by being formed integrally with each other.

The first portion may be provided with means, such as an enclosed or partially enclosed channel, to carry and conceal wires and cables. Alternatively the second portion may be provided with means, such as a channel in the third side thereof, to conceal wires and cables.

The component may be provided with means to receive an elongate bracing portion which also acts to conceal the fixing of the first portion to the building.

4 The end of the first portion distant from the second portion is preferably provided with an upturned lip and the third side of the second portion is preferably provided with a channel. The bracing portion is preferably held in position between the lip and the channel, concealing the fixings of 5 the first portion.

The bracing portion adds strength and rigidity to the system by acting as a brace between the first and second portions of the component. The bracing portion may include any number of decorative finishes to enhance the appearance of the final product.

The presence of the bracing portion also creates a channel between the bracing portion and the first portion of the component which can be used as a concealed cable or wire run, for example, for television antennas telephones, security lighting and the like. The bracing portion also conceals and weatherproofs the fixings.

Alternatively a barge board may be secured to the building such that it overlies the first portion of the component thus concealing the fixing thereof and creating a brace for the second portion of the component.

In a second aspect of the present invention the first and second portions may be formed separately and then connected together, for example, by mechanically interengaging parts, securing means or bonding.

Preferably the first and second portions of the component co-operate by male-female co-operation.
