Is Dry Verge better than mortar?
The most obvious advantage is durability, the plastic verge caps should last you a minimum of 10 years and require very little maintenance in comparison with sand/cement mortar. In effect you won’t need to worry about your roof leaking in or any pesky birds, bees or wasps nesting in your roof!

Since the introduction of BS 5534, dry ridge is now a building control requirement for all new roofs, meaning any new roof must have a dry ridge system unless the building is a listed building or is within a conservation area. However, repairs to existing roofs are excluded.
The advantages of a dry ridge system are as follows:
Your ridges won’t blow off – Dry ridges (when installed correctly) will not blow off under normal conditions, massively reducing the risk of storm damage. This is one of the main reasons it became a building code requirement. No more ridge plates flying on the ground, your car, your conservatory or, more importantly, your loved ones after high winds.
Maintenance – Unlike mortar there is nothing to maintain, a dry ridge system effectively leaves your ridges maintenance free.
Ventilation – The dry ridge provides discreet ventilation of the roof space and helps prevent harmful condensation.
Movement – Believe it or not, roofs move. This can happen through vibration (near main roads or train tracks) or through natural expansion and contraction. The dry ridge allows all kinds of movements. Your roof is built on a timber structure that is constantly flexing and moving, a dry ridge system allows this without cracking and degrading traditional sand/cement surfaces.
Different types of dry ridge systems
Dry Ridge comes in two types, although similar to each other they may have their own specific attachment systems. As time goes by so does the technology we use and good dry fix ridge kits are now available that work for both ridges and ridges. This is called a universal dry-first system.
How does a dry verge system work?
Dry verge systems, or dry-fixing, is a roofing system that involves caps or verges that interlock, clipping over the edge of the roof tiles, protecting the tiles, keeping them secured and preventing water and pests from entering the roof space.

What is a rim?
A roof edge is the part of the roof where the tiles end, where the roof meets the gable. Traditionally, a roof edge is attached with mortar to create a waterproof and weatherproof finish.
What is a dry edge?
Dry edge systems or dry fastening are roofing systems that use caps or edges that interlock and snap over the edge of the roof tiles, protecting the tiles, securing them and preventing water and pests from entering the roof space.
Why choose a dry edge system?
Traditionally, roof edges, the outer ends of the roof at the gable ends, are attached with mortar – known as wet verge. This is done to prevent critters and water from entering your roof surface. The problem with a wet edge trim is that grout is not very durable – thermal movement and expansion can cause cracks in the grout, and weather can also contribute to grout deterioration over time. This means that wet banquet systems require a high level of maintenance, such as B. repointing, to ensure that they are functional.
A dry shoulder system offers the same protection as a wet shoulder system, but with a number of advantages.
Dry banquet systems are typically made from plastic, which offers a longer lifespan and also requires less maintenance. Additionally, plastic dry edges can give your home a consistent, clean, and attractive finish, which helps increase potential resale value.
Dry banquet systems can be purchased with built-in vents that allow ventilation into the roof space. This helps reduce the occurrence of dampness and mold in the roof, as well as the amount of warm air and moisture in the attic.
How to customize a dry banquet
The simple installation process is another benefit of dry edge systems. Due to differences in designs and manufacturers, each dry edge system may have slightly different installation procedures, so we always recommend following the manufacturer’s instructions. However, we’ve created a quick guide below to outline the steps required to customize a dry banquet.
Step 1:
Install underlay if required and ensure all battens extend 20-40mm beyond the gable wall or vestibule – they must extend the same length to create a straight and even line. If the battens are rotten or showing signs of wear, the alternative is to fit a batten strip along the verge instead.
Step 2:
Attach the batten end clips to the end of each batten. This creates a safe place where you can attach the verge elements.
Step 3:
Install the eaves unit over the first tile. This prevents pests and water from entering the roof but also serves as a secure unit for the eaves clips to attach to.
Step 4:
Attach the eaves unit to the verge using the screws provided. This can also be attached to the panel with the L-shaped clip.
Step 5:
In some cases the verge units are suitable for both left and right hand verges – in this case simply remove the tab to make the verge suitable for the side you are working on. If not, just make sure you have the correct verge unit for the site you are working on.
Secure the first verge unit over the eaves unit and then slide along until the end is flush with the edge of the roof tile. When this is done, nail the top of the verge assembly into the batten end clip.
Step 6:
Place the second verge element in the slots of the first (if the product has slots). If you are working on a “Flex” dry edge system, open up the edge unit and slide it onto the end of the first verge unit, making sure the end of the shoulder lines up with the end of the end and nail the top into the Latte end clip.
Step 7:
Repeat this process on each side of the gable until you reach the peak of the roof.
Step 8:
Terminate the dry verge system with an end cap or block end using the screws provided or using the method shown in the manufacturer’s instructions.
How much does a dry strip cost?
When renovating an existing roof, it can be difficult to decide between a repointing mortar or the use of plastic dry edge caps. Dry edge capping is a bit more expensive than repointing in general, but the benefits it offers are worth the cost. Dry verge caps cost more but last much longer. They are manufactured to be durable and stand the test of high speed winds whereas grout requires regular maintenance and checking to ensure it is still in place.

Dry Verge Installation
Following changes to the British Standard Code of Practice for slate and roofing tiles, perimeter roofing tiles are now required to be double fastened. A dry edge is a great solution that not only conforms to BS 5534 but also provides a mortar free edge and secondary mechanical fixing for perimeter tiles.
Dry verge systems are easy to install and because they are ambidextrous, they can be field adjusted to fit the left or right edge of a roof. This means only one rim is required instead of two.
Dry edges typically come in packs of 10 which contain everything you need to secure them in place including batten end clips and stainless steel nails. In this blog we will guide you step by step through the installation of dry edges.
What you need:
document
tile slats
batten end clips
eaves closing unit
First end cap
Step One – Pinning the dry edge
Install the pad according to the manufacturer’s instructions. Extend the tile battens 45mm beyond the house parapet, brickwork or gable ladder – ensure all battens protrude equally to ensure a straight verge line.
Step Two – Attach the batten end clips
Install the batten end clips with the supplied nails. The batten end clip should be attached to the end of each tile batten to provide a secure attachment for the verge members.
Step Three – Attach the eaves fastener
The eaves finishing element is to be fitted over the first brick in the course of the eaves. This closure unit prevents birds and water from entering the roof and provides the mounting location for the eaves clip. Once installed, attach the verge board with the supplied screws through the appropriate holes in the eaves unit. It is possible to attach the eaves edge to the parapet with the supplied L-clip.
Step 4 – Prepare the Rapid Verand units
Depending on whether you need the right or left side of the roof, snap in the appropriate tab as marked. Clamp the first unit over the eaves unit and slide towards the ridge until the end is flush with the end of the roof tile. Secure the head of the quick verge unit into the batten end clip attached to the first batten and nail it through the most appropriate hole using the fasteners provided.
Step Five – Laying the Dry Shoulder
Place the second rapid feed assembly into the top and bottom slots of the first assembly. Push it in until you are sure the top and bottom legs are properly snapped in towards the ridge until the tail is flush with the roof tile. Attach the head of the second quick verge to the batten end cleat as in the step above and continue in this manner until the length of the verge reaches the ridge.
Step Six – The Top Course
Attach a ridge comb to the top of the ultimate quick verge unit, this comb will prevent birds and insects from entering the roof. Slide the Ultimate Fast Hard Shoulder Unit back in the direction of travel until the end of the unit meets the end of the roof tile.
Step Seven – Completion
Repeat these steps to create the shoulder on the other side of the ridge, making sure the ridge combs are attached to the last shoulder units. Make sure this is done correctly and that they interlock properly at the crown. Finish the ridge with either a ridge end cap or a block end ridge.
Matching dry edge to old roof
If you are attaching your Dryedge to an existing building you will need to remove any old underclock and engine bedding prior to attachment. A batten can then be installed running from the eaves to the ridge to provide a base for attaching the units.

Fitting Instructions for Continuous Dry Verge
Pre-Installation Requirements for Continuous Dry Shoulder Type S (Slate)
Ensure all health and safety guidelines are followed.
Fascia Expert Continuous Dry Banking Type S is suitable for most applications and building types including residential, commercial and industrial.
Installation Procedure for Type S (Slate) Continuous Dry Strip
Roof battens need to be fixed to the required slate thickness, however the batten ends are not yet fixed to allow the slate verge 60mm flange to be fitted under the batten which is the simplest type of fitting.
The ends of the battens are then securely fixed by nailing them through the batten and verge into the timber rafter.
The slate verge profile is then at an angle made in this way so that the top flange will clamp onto any thickness of slate, from 5/6mm general slate to 12/13mm natural slate.
To open the outside of the slate verge, a temporary batten is inserted between the batten layers, which is pushed against the inside of the slate verge and nailed there. This opens the profile of the verge to a vertical position.
The slates are fastened in place in the usual manner, with the outside edge of the slate being fastened against the inside edge of the shoulder strip.
This will hold the edge in the vertical position and this process continues up the edge of the roof in the usual way.
Continuous Slate Dry Verge achieves a professional finish on any type of sale that is used.
Pre-Installation Requirements for Type D Continuous Dry Edge Strip (Tile)
Ensure all health and safety guidelines are followed.
Fascia Expert Continuous Dry Banking Type D is suitable for most applications and building types including residential, commercial and industrial.
Installation Procedure for Type S (Slate) Continuous Dry Strip
Fascia Experts Continuous Dry Banking should be cut to the required length to allow a plumb cut at the ridge and approximately 150mm longer than the rafter. The horizontal flange is cut away to allow fitting over the felt pad on the eaves.
The slats are laid against the lip of the dry shoulder’s water channel which are then nailed into position directly through the shoulder’s horizontal fin.
The nails are fastened through the batten as well as through the verge in the wooden rafter.
A close-up of the installed roof battens shows their position at the lip of the drainage channel.
Once all the battens are in place and the dry edge is secure, the roof is ready for tiling.
The roof tiles are fitted as usual, taking care to insert the verge stones fully into the continuous dry verge where the top flange will hold them securely in place.
At the eaves, the verge should be cut square and flush with the bottom tile.
Rainwater can run off directly into the rain gutter through the water gutter.
The built-in, continuous drying rim provides a professional finish. This applies to any roof tile or slate used.
The completed roof provides full continuous coverage against water ingress and added strength against wind damage by firmly attaching the end tiles.
