Choosing the Right Dry Ridge System

A dry fix ridge system mechanically secures ridge tiles without relying on mortar as the fixing method. Depending on the product, a kit typically combines a ridge roll with unions, clamps, screws and other components required to form a secure ridge.

The right system depends on the roof covering, ridge tile, roof design and length required. Always check compatibility and the manufacturer’s installation instructions before ordering.

What Are the Benefits of Dry Fix Ridge?

Dry fixing avoids relying on mortar to secure ridge tiles. Mechanical components hold the ridge tiles in position while allowing the system to accommodate normal roof movement.

Depending on the product, other benefits can include:

• Mechanical fixing of ridge tiles
• Mortar-free installation
• Integrated ridge ventilation
• Weather-resistant ridge detailing
• Reduced maintenance associated with failing mortar
• Faster installation in suitable conditions

Performance and ventilation provision vary between systems, so compare the individual specifications before choosing.

Which Dry Ridge Kit Do I Need?

Start by checking compatibility with your roof covering and ridge tiles.

Some systems are designed as universal solutions for a range of concrete tiles and slates, while others have more specific applications. You should also check whether the kit is intended for ridge use only or can form part of a compatible hip installation.

Before ordering, consider:

• Roof covering
• Ridge tile type
• Roof pitch
• Total ridge length
• Kit length
• Ventilation requirements
• Components included
• Manufacturer compatibility

Checking these details first helps avoid buying a system that does not suit the roof.

What Length Ridge Kit Do I Need?

eRoofing stocks options in several lengths, including 3m, 6m and 10m kits.

Measure the complete ridge length before ordering and check the usable coverage provided by the individual system. For longer ridges, multiple kits may be required.

Do not assume the nominal roll length always equals the exact finished coverage without checking the manufacturer’s installation guidance.

Dry Ridge and Roof Ventilation

Many systems incorporate ventilation along the ridge as part of their design. This can help provide high-level ventilation where required by the roof construction.

However, ventilation performance varies between products. The ventilation strategy should be considered as part of the complete roof design rather than assuming every kit provides the same airflow.

Check the manufacturer’s stated ventilation performance and installation requirements for the chosen system.

Dry Ridge, BS 5534 and BS 8612

Current roofing standards require ridge and hip tiles to be securely mechanically fixed rather than relying on mortar alone.

BS 8612 sets performance requirements for dry-fixed ridge, hip and verge systems used with slating and tiling. When selecting a system for a project where compliance is required, check the manufacturer’s current certification and technical documentation.
