What Is a Dry Verge?

A dry verge is a system used to secure roof tiles at the edge of a roof. It consists of a number of components, including verge boards, verge clips, and hip tiles. The system is designed to allow for movement in the roof structure, while still providing a secure fixing for the tiles.

Dry verges are most commonly used on pitched roofs, but can also be used on flat roofs. They are an alternative to traditional mortar bedding, which can be more time-consuming and difficult to install.

The Advantages of Using a Dry Verge?

Unlike traditional methods, which require the use of mortar or other adhesives, dry verge systems rely on interlocking components that are mechanically fastened to the roof. This provides a number of advantages, including ease of installation, improved durability, and enhanced resistance to wind and weathering.

In addition, dry verge systems can be used with a variety of tile types and profiles, making them an ideal solution for both new construction and retrofit projects. As a result, dry verge systems have become the preferred choice for many builders and roofers.

How To Fit Dry Verge?

Dry verge is easy to install and can be fitted onto most types of roofs. The first step is to measure the length of the eaves and then cut the dry verge to size.

1) Installing Underlay

Underlay is not needed in some instances but we would recommend installing it to help protect the verge from wind and weather damage.

Cut a strip of underlay to size and nail or staple it into place along the length of the eaves. Make sure that the underlay is overlapped by at least 75mm at each end.

If you are fitting dry verge to an existing roof then you will need to install some type of support system. This is usually done by nailing battens onto the roof and then attaching the dry verge to the battens.

The size of the batten will depend on the width of the verge but they should be no more than 400mm apart.

2) Fitting the Batten End Caps and Eaves Closure Units

Once the underlay has been fitted and the support system is in place you can start to fit the dry verge.

Start by fitting a batten end cap to each end of the roof. These are simply pushed into place ensuring that the flanges are pointing downwards.

Next, fit an eaves closure unit to each side of the roof. Again, these are simply pushed into place and screwed into place for extra security.

You may need to trim the ends of the battens to get a neat fit. Once the end caps and closure units are in place you can start fitting the dry verge units themselves.

3) Fitting the Verge Units

Check that the verge units you are installing are suitable for the type of roof you have. Simply clip the first unit into place on the end of the first batten.

Ensure that the flanges are pointing downwards and use screws to secure them in place. Repeat this process until all of the verge units are installed.

The next step is to install the hip end cap which will sit at either end of the row of verge units.

Once you have completed these steps, your dry verge system will be installed! If you have any questions or need assistance, please don’t hesitate to contact a professional roofer at Avoncraft Roofing Services. We’re always happy to help!
