Dry ridge system over traditional mortar

A mechanical fixed ridge system, commonly referred to as a dry ridge system, is a method of securing the ridge tiles (the tiles that run along the peak of the roof) without using traditional mortar. Instead, the system uses clips, screws, and other mechanical fasteners to secure the ridge tiles in place.

Benefits of a Dry Ridge System

1. Durability and Longevity:

   • Dry ridge systems are much more durable than mortar-based ridge systems. Mortar can crack, crumble, and eventually fail due to weather exposure, leading to potential water ingress and damage. A dry ridge system, on the other hand, is designed to withstand harsh weather conditions, including strong winds and heavy rainfall.

2. Low Maintenance:

   • Once installed, dry ridge systems require very little maintenance. Since there is no mortar to deteriorate, there's no need for periodic repairs or replacements that are often necessary with traditional ridge tiles.

3. Improved Ventilation:

   • Many dry ridge systems are designed to incorporate roof ventilation. This helps prevent the build-up of condensation within the roof space, which can lead to dampness, mould, and timber decay. Adequate ventilation is essential for maintaining the health of the roof structure.

4. Ease of Installation:

   • Dry ridge systems are easier and quicker to install compared to traditional mortar-bedded ridges. They can be installed in various weather conditions, which reduces the risk of delays during construction or repair. The system involves fixing a ridge roll along the ridge line, then securing the ridge tiles with clips and screws.

5. Weather Resistance:

   • The mechanical fixings used in dry ridge systems provide a secure and consistent hold, making them highly resistant to wind uplift and storm damage. This is particularly important in regions prone to severe weather.

6. Compliance with Building Regulations:

   • In many areas, building regulations have become stricter, requiring more secure and weather-resistant methods of fixing roof components. Dry ridge systems often meet or exceed these regulatory requirements, ensuring compliance and improving the overall safety of the roof.

7. Enhanced Aesthetic:

   • Dry ridge systems offer a neat, uniform appearance along the ridge line. They are available in various colours and finishes to match or complement the roof tiles, enhancing the overall look of the roof.

8. Pest Prevention:

   • The secure fitting of dry ridge systems helps prevent pests, such as birds or rodents, from entering the roof space, which can be a common problem with deteriorating mortar.

How a Dry Ridge System Works

1. Ridge Roll:

   • A flexible ridge roll is installed along the ridge, providing a base for the ridge tiles and allowing for ventilation.

2. Mechanical Fixings:

   • Ridge tiles are secured using clips or clamps and stainless steel screws that are fastened into a ridge batten beneath the tiles. This ensures that each tile is firmly attached and aligned.

3. Tile End Caps:

   • End caps are used to finish the ends of the ridge, ensuring a tidy and weatherproof seal.

Overall, a dry ridge system offers a modern, durable, and maintenance-free solution for securing ridge tiles, providing significant advantages over traditional mortar-based systems.
