What is a Dry Verge System?

A dry verge system is a roofing accessory used to cover and protect the edges of roof tiles on gable ends (the sloping sides of a roof). Unlike traditional methods that use mortar to secure roof tiles, a dry verge system involves using specially designed plastic or metal caps that clip or screw onto the edges of the roof tiles.

Benefits of a Dry Verge System

1. Durability and Longevity:

   • Dry verge systems are more durable than mortar, which can crack and deteriorate over time due to weather conditions. The plastic or metal materials used in dry verge systems are resistant to UV radiation, frost, and rain, ensuring long-term protection.

2. Low Maintenance:

   • Once installed, dry verge systems require little to no maintenance, unlike mortar, which may need regular checks and repairs. This makes them a more cost-effective solution in the long run.

3. Improved Weather Protection:

   • Dry verge systems provide a tight seal against wind, rain, and snow, reducing the risk of water ingress and wind uplift. This helps prevent damage to the roof structure and interior of the building.

4. Enhanced Aesthetic Appeal:

   • Dry verge caps give a neat and uniform appearance to the roofline, which can enhance the overall curb appeal of a property. They come in various colours to match the roof tiles or shingles.

5. Easy Installation:

   • The installation process for a dry verge system is relatively straightforward and can be done in various weather conditions. This reduces installation time and labour costs compared to traditional mortar bedding.

6. Prevents Pest Infestation:

   • The secure fitting of dry verge systems helps block entry points for birds, insects, and rodents, which might otherwise find their way into the roof space through gaps in the mortar.

7. Compliance with Building Regulations:

   • Many building regulations now recommend or even require the use of dry verge systems because of their superior performance in preventing roof edge damage and ensuring a longer lifespan of the roofing system.

Overall, a dry verge system is a modern and effective solution for protecting and enhancing the edges of a roof, offering significant benefits over traditional mortar-based methods.
