Dry Verge Systems

Fitting a dry verge system is a simple way for homeowners to secure the roof tiles along the edge (or verge) of their roof. In contrast to traditional wet verge systems using mortar, a dry verge made from plastic is durable, easy to install and requires minimal maintenance. Roof verges are designed primarily to prevent both pests and water getting into your roof space. Dry verge systems are vastly superior for these purposes, as the UPVC or GRP material is totally waterproof, and will not deteriorate over time like mortar.

We work with a number of leading manufacturers to offer our customers with a brilliant range of dry verge systems. These include dry verge caps and units from brands such as Envirotile, Tapco, Britmet and Ariel Plastics. Each of these manufacturers is renowned for their commitment to quality and continuing innovation. Thanks to their use of modern UPVC and GRP plastics, their products for dry verges are both incredibly reliable and lightweight, making them simple to install for homeowners and tradespeople alike.

To ensure that your new dry verge matches the appearance of your current roof tiles, we supply dry verge systems in a wide variety of colours and finishes. So no matter the finish you’re looking for, your dry verge will provide a clean, attractive finish that blends in perfectly with your home.

Dry Verge Materials

UPVC Dry Verge Roofing Systems

UPVC is the most common material used in dry verge systems today. UPVC helps to provide a secure, watertight finish to your roof verges. These systems can be installed on roofs with most types of tile, including concrete, clay interlocking and plain roof tiles. UPVC dry verges are most commonly used for continuous dry verge systems.

GRP Dry Verge Roofing Systems

GRP or Glass Reinforced Plastic dry verges share many of the advantages of UPVC systems. Choosing GRP, you’ll achieve a wonderfully clean, modern finish to your roofline that will be watertight and stand the test of time with minimal maintenance. The primary advantage of GRP over UPVC is its added strength, making it a good option for homes more exposed to extreme weather conditions.

Types of Dry Verge System

Continuous

Available in both UPVC and GRP, continuous dry verge systems allow for easy installation as the units are simple to interlock together, forming a single continuous unit which protects the roof space. These systems are shaped to fit together perfectly along your roofline, giving you a perfect waterproof seal when installed correctly. Available in a number of profiles and finishes, continuous dry verge systems are an ideal finishing touch to your roof.

Individual

We also provide individual dry verge units which provide many of the same benefits as continuous systems. These individual units offer the same reliability, durability, easy installation and low maintenance across their lifespan. The key difference is that rather than fitting along the entire verge as a single, continuous unit, individual dry verge systems are sectional, designed for one course of tiles.

What is a Dry Verge?

Dry verge systems are an incredibly popular alternative to traditional wet verge systems, using innovative modern plastics instead of mortar. These new materials not only do the job better, but they have very few of the disadvantages of mortar. UPVC and GRP plastics are 100% waterproof and will repel any pests trying to invade your roof space. They also do not experience thermal movement, and therefore won’t suffer cracks. Dry verge systems are very light and easy for homeowners to install and require virtually zero maintenance. In contrast, mortar verges are highly susceptible to damage and wear over time, requiring maintenance and repointing.

How Much Do Dry Verges Cost?

If you’re refurbishing an existing roof, it could be cheaper to repoint the mortar instead of replacing it with a dry verge system. However, when you consider future maintenance costs in terms of time and money, dry verges win every time. Once installed, all they’ll need is a quick once-over and a clean to remove any debris to keep them in top condition for years.

How Much Should A Dry Verge Overhang?

The exact amount of overhang required depends on the materials used in your roof tiles, roof battens and so on. A dry verge shouldn’t hang more than 40mm over the side however, as this can make the verges more susceptible to being damaged by high winds. We’d recommend an overhang of roughly 25-30mm, however you should always consult the manufacturer’s recommendations to be certain.

How Do You Fit a Dry Verge?

Just how simple they are for anyone to install, whether they’re a professional or a handy homeowner is one of the many benefits of dry verge systems. Of course, each system will be slightly different so you should always follow instructions from the manufacturer, but below you’ll find a handy guide outlining the main steps.

Inspect the tiling battens to make sure they aren’t rotting or damaged. If they are, you could fit a batten strip along the verge.
If required, install the underlay and ensure that the battens extend beyond the gable wall evenly by between 20 and 40 millimetres.
Fix batten end clips to each batten to add a secure place to fix each verge unit.
Fit the eaves closure unit over the first tile. This will help to act as a secure unit for eaves clips.
Now, fit the eaves closure unit onto the barge board or fascia board.
Clip the first verge unit over the eaves closure unit, and slide it along until it lines up with the edge of the roof tile. Then, nail the top of the unit onto the batten end clip.
Position the second verge unit so it can clip or slot into the first, nailing the top of this second unit onto the batten end clip.
Repeat the above until you’ve reached the apex of your roof.
Finish off the system using an end cap or block end.
Enjoy the clean, modern finish you’ve just given your roof!
