The benefits of dry ridge and verge systems
This article outlines the benefits of dry ridge and verge systems and why changes in roofing technologies have helped storm proof your roof.
For many years the roofing industry has relied on mortar to bed ridge, valley, verge and hip tiles. However as you will read, mortar has many disadvantages and as technologies have developed, building regulations now require all hip and ridge tiles to be mechanically fixed using a dry fixing ventilating system.
The use of ‘dry ridge and verge systems’ obviate the need for mortar. Mortar is unreliable and liable to cracking, it requires regular maintenance, doesn’t provide sufficient protection to wind uplift and is very susceptible to water penetration. It also has difficulty bonding to the surface of fibre cement slates and this can lead to damage in storm conditions and premature failure at other times.
Therefore, dry fixing methods have been developed which are far more reliable and greatly reduce the risk of storm damage. The installation of dry systems tends to be much more efficient, and in turn this results in saving on labour costs.
Unlike mortar bedded systems, dry hip / ridge systems require very little maintenance. With many of these details being located in the most vulnerable areas of the roof, ensuring the system is fixed in the most efficient will offer the necessary protection.
‘Dry ridge and verge systems’ negate the need for high level ventilation tiles as the systems today are designed to provide levels of ventilation that wasn’t possible with traditional materials. This in turn results in allows for air circulation within the roof space mitigating the chances of condensation build up and all the consequences that has.
