Danelaw® offers a variety of solutions that are cost effective and time-saving, providing a range of dry ridge systems that can also be used for the hips.
Current requirements and demands now for mechanically fixed ridge and hip tiles are met with Dry Fix Ventilated Ridge systems, the default option to mortar bedded methods, providing secure fixing against worst of the weather as well as ventilation to the roof. The Danelaw® CON6+ dry ridge system meets the brief and can be used for the hips and ridges of the roof with a 15-year guarantee. The addition of the CLAY6+ dry ridge and hip system has been designed to suit all commonly available clay and baby ridge tiles. The final solution Hambleside Danelaw offer is the MONO6+ dry ridge system, which is compatible with most mono ridge tile profiles.
Hambleside Danelaw have been developing and manufacturing dry fix solutions since the late 1990s, focusing on creating products that are high quality and cost effective. To learn more about the dry fix products that Hambleside Danelaw offer, please refer to our Back to Basics article on the topic.

The stainless steel ridge batten straps supplied with the kit are the simplest and most convenient way of securing multiple battens at the ridge on trussed rafter roofs, and may also be used on traditionally cut roofs that incorporate ridge boards or ridge trees. These straps are used in the load testing required under the BS 8612 dry fix Standard for ridge fixing to demonstrate compliance.
Straps are generally not required on the hips, however the hip battens and any hip packer battens must be screwed to the roof structure and not nailed.
We also have a range of fixing kits available depending on the application – download the datasheet here
Yes, however it will be necessary to trim the jointing gasket length to suit the baby ridge and the roll will require a ‘tuck’ under the tile to reduce the effective and visible width of the Rollflex strip.
Yes, the jointing gasket is uniquely designed to facilitate this. It requires drilling the capping section of the ridge tile to receive the main fixing screw and snipping off the side of the ‘T’ tabs on the side of the gasket. A detail showing this is available upon request.
Yes, in some situations it can however it is dependent on the ability to be able to securely fix the ridge tile. The supporting timber below the ridge tile may need to be increased in height to allow this fixing and an extra piece of flashing material may be required, subject to detail, at the bottom of the vertical side of the tile.
The system is designed to be used at the minimum pitch that is recommended for the slates and tiles that are being used. In low pitch applications, it may be necessary to build the ridge battens or ridge tree higher to accept the stainless steel screw supplied with the kit.
This is generally not a limitation of the kit, unless deeply profiled tiles are being used at very steep roof pitches.
Because there is no mortar packing to compensate, it is important with all dry fix ridge and hip applications that the ridge or hip tile is chosen for compatibility with the roof pitch and the external roof covering slate or tile. The edge of the ridge or hip tile should sit on the corrugated metal strip.
The centre strip is a polypropylene fabric perforated to meet BS 5250 ventilation requirements with a corrugated aluminium edge strip to suit all profile tile requirements. This also contains a wider and thicker butyl adhesive strip than is offered with many other systems.
Like all products, ‘there are a range of quality and function available to purchase’. The quality, function, durability and usability of the components can all vary, and some kits may not be truly universal or been fully tested to the recently introduced British Standard for dry fixed ridge, hip and verge products.
Many costs of producing these kits and getting them to market can be similar, therefore small increases in cost can deliver a much better product.
