ROOF VERGES
THE ROLE OF A ROOF VERGE
A verge is the section of a pitched roof where the tiles or slates meet the gable end. It’s a key part of the roofline that helps protect against wind uplift and rainwater penetration while providing a clean, secure edge. Over time, this area can become one of the most vulnerable points on a roof due to its constant exposure to the weather.
At Rogers Roofing, we replace and repair both cement verges and dry verge systems, making sure each installation suits the roof type and tile profile. Our work ensures the verge not only looks neat and professional but also performs as intended for years to come.
DRY VERGE SYSTEMS
Modern dry verge systems have become the preferred choice for many homeowners due to their strength, clean appearance and low maintenance. Unlike traditional mortar verges, which can crack and loosen over time, dry verge units are mechanically fixed, providing a secure edge that resists movement and weathering.
We exclusively install Klober dry verge systems, including the Uni Click and Continuous Dry Verge ranges. These products are designed with resistance to UV in mind, helping the colour and finish stay consistent for years without fading or brittleness. They offer a professional, long-lasting finish that works with a wide range of roof coverings. Klober’s systems meet BS 5534 and BS 8612 standards and are built to handle the challenges of wind, rain and temperature changes without the need for regular maintenance.
The Uni Click system is known for its interlocking design, which ensures a consistent fit along the roofline and helps to prevent gaps where water or pests could enter. The Continuous Dry Verge system provides a sleek, uninterrupted finish with strong mechanical fixing, ideal for homeowners looking for a discreet, modern appearance.
Dry verge systems also provide additional ventilation and eliminate the common issues caused by cracked or missing mortar, giving you a long-lasting and tidy roof edge that doesn’t need ongoing upkeep.
DRY VERGE INSTALLATION PROCESS
For every dry verge installation, we strip the roof tiles back around three rafters and remove the existing battens. A new run of breathable membrane is then laid to the verge area to improve weather protection and ventilation.
We then re-batten the roof using battens that meet current building standards, ensuring they are evenly spaced and securely fixed. The breathable membrane is wrapped around and over the verge edge, creating a small upstand that helps prevent water from tracking back beneath the tiles. This simple detail is key to keeping the roof edge watertight and directing any moisture away from the structure.
Once the base is prepared, the roof is re-tiled, replacing any damaged tiles, and the Klober dry verge system is installed. Each unit is fixed mechanically for a neat, secure finish that resists movement and provides long-term protection from wind and rain.
CEMENT VERGE REPLACEMENTS
While dry verge systems are now standard on most new roofs, many older properties were built with cement verges. These can last for years if installed correctly, but exposure to the elements eventually causes mortar to crack, loosen or fall away. When this happens, it can leave the edge of the roof exposed to wind and rain, leading to water ingress and broken tiles.
At Rogers Roofing, we carry out full cement verge replacements as well as localised repairs where appropriate. Damaged mortar is removed, and the verge is re-bedded using a strong, weather-resistant mix. We always ensure proper overlap and alignment with the roof covering, creating a neat, uniform finish that restores both appearance and performance.
In some cases, homeowners choose to replace their existing cement verges with a modern dry verge system for a more durable, maintenance-free solution. We’re always happy to advise on the most suitable option depending on the roof type, age of the property and desired finish.
CEMENT VERGE INSTALLATION PROCESS
When carrying out a cement verge replacement, we first remove the existing mortar and any loose or damaged verge tiles. The undercloak beneath is then replaced to provide a solid base for the new verge. It supports the mortar between the undercloak and the tile, ensuring a clean, strong edge that resists movement and water ingress.
For this type of work, the existing battens and breathable membrane are inspected and only replaced if required or at the customer’s request. This approach avoids unnecessary disruption while ensuring all materials remain sound and fully functional. Once the base is prepared, the verge tiles are carefully re-bedded using Remix Roof Tile Bedding Mortar, which provides a consistent colour and mix for a uniform, durable finish.
The completed verge is neatly pointed and shaped to provide a clean, professional appearance while sealing the roof edge against wind and rain.
WHY A PROPERLY FITTED VERGE MATTERS
A well-fitted verge protects against wind uplift, driving rain and pest entry, helping to maintain the overall performance of the roof. Poorly installed or incompatible verge systems can lead to water ingress, staining and long-term structural damage. By using the correct materials and installation methods, we ensure every verge we fit performs exactly as it should, offering both reliability and a smart, tidy finish.
