Dry Ridge

 Dry Ridge systems come in a variety of designs but offer a similar level of performance.

When using dry ridge systems the mortar joints between ridge tiles are replaced by plastic inserts, known as unions, that create the visual appearance of a mortar joint but have a hidden weather proofing system that carries away the water.

 

The next significant component of a dry ridge system sits between the ridges and the tiles of the roof slope. This part of the system usually includes a ventilated strip that ensures moisture laden air is vented from under the tiles

The edges of the roof where it meets the gable is called the 'verge'.

Traditional 'wet' verges

Traditionally the tiles where, and still are, mortared to prevent the wind and rain from lifting the tiles and allowing the rain to penetrate the roof space, which may cause problems with dampness and possibly tile movement.

Mortar verges

The downside to this is that they need maintenance - the weather will eventually cause the mortar to crack and crumble.  Birds or small animals may also gain access to the roof space which again brings problems to the householder. 

 Dry verge systems help avoid these defects and the need for periodic maintenance of the mortar bedding. For many tiles, special 'cloaked verge' tiles are available which neatly close the gap at the verge. Alternatively plastic dry verge systems are available which suit most tiles.

 

These are available in single units, i.e. one piece per tile course, or in continuous lengths. These are attractive and highly functional ways to improving the overall appearance of your roof. The systems are easy-to-use and provide a neat, secure and mortar-less finish at roof verges.

 


A dry verge system will also reduce the risk of wind damage, water penetration and will stop small animals getting into the roof space.

 

Dry verge systems also allow for the natural movement of the building, which the mortar type does not.
