What is a Dry Verge?
A dry verge is a mortar-less roofing system used at the roof's edge, specifically on the verge (the junction between the roof surface and the gable end of the building). Dry verge systems are typically made of plastic, are easy to install, and provide a neat, durable, and weatherproof finish to the edges of a roof.
Contrary to traditional methods using mortar, dry verge systems do not deteriorate with weather exposure, making them a highly efficient roofing solution. Their durable construction and ease of installation make them a popular choice for homeowners in Ireland.
The Advantages of Using a Dry Verge
A dry verge offers several advantages when it comes to fitting it to an existing roof. These benefits include:
- Improved aesthetics: A dry verge provides a clean and neat finish to the edges of the roof, enhancing the property's overall appearance.
- Enhanced durability: By protecting the edges of the roof, a dry verge helps prevent any damage caused by exposure to weather elements and reduces the risk of water ingress.
- Reduced maintenance: With a dry verge, there is less need for regular maintenance as it provides a secure barrier, eliminating the need for repointing or rebedding mortar.
- Easier installation: Installing a dry verge is a straightforward process that can be carried out quickly and efficiently, saving time and effort compared to traditional mortar methods.
- Long-lasting performance: Dry verges are designed to withstand harsh weather conditions and have a longer lifespan than mortar alternatives, ensuring long-term protection for your roof.
Additionally, it's worth noting that dry verges are available in different colours and styles, allowing you to choose an option that complements the existing aesthetics of your property. So not only do they offer practical benefits, but they also provide an opportunity to enhance the visual appeal of your home with ease.
How to Fit Dry Verge?
Fitting a dry verge to an existing roof requires precision and expertise. To help you with this, we have created a step-by-step guide on how to fit dry verge seamlessly.
1. Preparation is key: Before starting the installation process, ensure you have all the necessary tools and materials ready. This includes dry verge units, fixing screws, a cordless drill, measuring tape, and a ladder for access.
2. Remove any existing mortar: Start by removing any old mortar or bedding from the edges of the roof tiles. This will provide a clean surface for fitting the dry verge units.
3. Install the first unit: Begin at one end of the roof edge and place the first dry verge unit. Make sure it aligns perfectly with the edge of the roof tiles. Use a cordless drill to secure it firmly in place with fixing screws.
4. Continue fitting: Proceed along the roof edge, attaching each subsequent dry verge unit in the same manner as before. Ensure each unit is positioned accurately and securely fastened to prevent movement or water ingress.
5. Finishing touches: Once all the dry verge units are installed, check for gaps between them and make any necessary adjustments for a seamless appearance. Finally, inspect your work to ensure everything is secure and visually appealing.
In addition to these steps, choosing high-quality dry verge units that are compatible with your specific roof type is essential. Proper maintenance and regular inspections can also prolong the lifespan of your dry verge system.
By following these guidelines, you can effectively fit dry verge to your existing roof while maintaining its integrity and enhancing its overall aesthetic appeal.
Installing Underlay
Underlay is an essential component when it comes to fitting dry verge to an existing roof. It provides a protective layer that helps prevent any moisture or water infiltration, ensuring the longevity of your roof.
Here is a step-by-step guide on how to install the underlay:
- Begin by measuring the length and width of the area where the underlay will be installed. This will help you determine the correct amount of underlay needed for your project.
- Clean the roof surface thoroughly, removing any debris or dirt that may be present. Ensure that the surface is dry before proceeding with the installation.
- Roll out the underlay, starting at one corner of the roof and working your way across. Make sure to overlap each row of underlay by a minimum of 100mm (4 inches) to provide maximum protection against moisture.
- Secure the underlay in place using roofing nails or staples. Place them approximately 150mm (6 inches) apart along each edge, ensuring a secure and tight fit.
- Trim any excess underlay using a sharp utility knife, making sure to follow the shape of the roof accurately. This will provide a neat and tidy finish.
- Once you have completed installing the underlay, it is crucial to check for any visible gaps or loose sections. Make adjustments and reattach as needed to ensure full coverage and protection.
Remember, taking care of small details like installing underlay can make a significant difference in prolonging the life of your roof and enhancing its overall efficiency.
Fitting the Batten End Caps and Eaves Closure Units
Fitting the batten end caps and eaves closure units is an essential step in installing dry verge on an existing roof. By following these steps, you can ensure your roofing project's secure and professional finish.
- Align the batten end caps with the edge of the verge trim on both roof sides. Use screws or nails to fix them securely in place.
- Next, attach the eaves closure units to the underside of the verge trim at each end of the roof. Ensure they are positioned correctly and tightly secured using appropriate fasteners.
- Once the batten end caps and eaves closure units are in position, check for gaps or spaces between them and make any necessary adjustments to ensure a tight fit.
- To further secure the installation, apply a generous amount of adhesive sealant along the top edges of the batten end caps and eaves closure units.
- After applying the sealant, press firmly on all sections to create a strong bond between the dry verge components and prevent water ingress.
- Finally, visually inspect your work to ensure everything is aligned properly and all fixings are secure before moving on to other areas of your roofing project.
These steps will help you successfully fit batten end caps and eaves closure units as part of your dry verge installation process, providing a neat appearance and protection against water damage and leaks.
Battening the Verge
To properly fit dry verge to an existing roof, it is essential to consider the process of battening. This involves creating a solid foundation for the dry verge system to be securely installed.
Here are some key aspects to consider when battening the verge:
- The first step is to ensure that the existing roof has a sufficient batten in place. A batten is a horizontal strip of wood or metal that supports and stabilises the roof tiles or slates.
- The batten should be securely fixed to the rafters, ensuring it is level and straight. This will provide a sturdy base for the dry verge system and prevent any movement or instability.
- It is important to use treated battens resistant to decay and rot, as these will provide long-lasting support for the dry verge system.
- The spacing between each batten should be consistent, typically around 600mm apart. This will ensure proper support and help distribute the weight evenly across the roof.
- When fixing the battens, using stainless steel nails or screws suitable for outdoor use is recommended. This will prevent corrosion and maintain the integrity of the battens over time.
- Finally, it is crucial to check that all battens are properly secured and aligned before fitting the dry verge system. Any loose or misaligned battens should be adjusted or replaced to guarantee a strong foundation.
By following these guidelines and taking care during the process of battening, you can ensure a successful installation of dry verge onto your existing roof structure.
Securing the Starter Verge
Securing the Starter Verge is crucial to fitting a dry verge to an existing roof. This ensures stability and prevents water penetration or damage. Here's a step-by-step guide on how to securely install the starter verge for your roof:
- Assess the condition of your roof and ensure it is clean and free from any debris. Remove any loose mortar or tiles that may hinder the installation process.
- Next, measure and cut the starter verge to the required length using appropriate tools such as a saw or tin snips. It should be long enough to cover the entire length of the roof edge.
- Once you have prepared the starter verge, position it at the bottom edge of the roof, ensuring it aligns perfectly with the eave of the roof.
- Securely fix the starter verge by using screws or nails at regular intervals along its length. Make sure to choose screws or nails that are suitable for outdoor use and can withstand weather conditions.
- To provide additional support, apply a bead of adhesive along the underside of the starter verge before fixing it to the roof edge. This will help create a strong bond between the verge and the roof surface.
- After securing the starter verge, check for any gaps or irregularities. Fill these gaps using suitable fillers or sealants to ensure a watertight seal.
- Finally, inspect your work to ensure that all fixings are secure and that there are no visible gaps or loose sections. This will guarantee that your dry verge system is properly installed and ready to protect your roof for years.
Following these steps, you can successfully secure the starter verge while fitting the dry verge to an existing roof. Remember to always prioritise safety and seek professional advice if needed.
Connecting the Dry Verge Pieces
Connecting the Dry Verge Pieces is an essential step in fitting the dry verge to an existing roof. This process ensures your roof's stability and durability while providing a neat and professional finish.
Here is a 5-step guide to help you connect the dry verge pieces:
1. Position the first dry verge piece:
Start by positioning the first dry verge piece at one end of the roof edge. It should be flush with the fascia board and the top of the gable end brickwork.
2. Secure the first piece:
Use screws or nails to secure the first piece in place. Ensure they are properly fixed into the fascia board and the gable end brickwork for maximum stability.
3. Connect subsequent pieces:
Align the next dry verge piece with the first one, ensuring that they overlap slightly. Secure it in place using screws or nails, just like before. Repeat this process for all remaining dry verge pieces, working your way along the roof edge.
4. Mitre corner joints:
When you reach a corner, you may need to mitre-cut the dry verge pieces to achieve a clean and seamless joint. This involves cutting each piece at a 45-degree angle to fit together neatly at a right angle.
5. Seal and finish:
Once all the dry verge pieces are connected, use a sealant or adhesive recommended by the manufacturer to create a watertight seal between each joint. This will further enhance their durability and protect against water ingress.
Following these steps, you can successfully connect dry verge pieces and ensure a secure and attractive finish for your existing roof.
When connecting dry verge pieces, it's important to note that each manufacturer may have specific instructions or variations in their installation process. Therefore, always refer to their guidelines or consult a professional if needed.
Fitting a dry verge to an existing roof adds aesthetic appeal and provides long-lasting protection against weather elements such as wind, rain, and snow. Now you can confidently undertake this project and enhance your roof's overall appearance and functionality.

Reducing Damp and Mildew in the Roof Space
Dampness and mildew in the roof space can lead to serious issues if not addressed promptly. To ensure a dry and healthy environment, follow these six steps:
- Inspect the roof space for any signs of moisture or dampness. Look for water stains, sagging insulation, or musty odours.
- Identify the source of the dampness. It could be a leaking roof, damaged gutters, or poor ventilation. Addressing the root cause is essential to prevent further damage.
- Repair any leaks or damage to the roof immediately. Replace missing or broken tiles, fix cracks in the chimney, and seal any gaps around vents or pipes.
- Improve roof ventilation by installing vents or fans. Proper air circulation will help reduce moisture build-up and prevent condensation.
