Dry Verge and Dry Ridge Roofing Systems
A verge refers to the junction between the roof and the gable end of the building.
A gable refers to the wall that infills between two opposite roof slopes and usually finishes in a triangular shape. The traditional way of finishing the roof at a gable wall is to use mortar.
Traditionally this detail includes a layer of plain tiles, slates or fibre cement board to assist in the weatherproofing. Unfortunately all too often this type of verge is poorly installed, leading to eventual water ingress.
When using dry fix 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.
Dry verge roofing combined with dry ridge systems remove the need for regular maintenance of the roof.
Over time, mortar can be damage by the natural movement of the building/roof. The wind and rain also help in penetrating the mortar and causing it to crack, crumble and eventually fall out which will cause brickwork and tiles to loosen.
When this occurs, repairs can be quite costly as scaffold access is often required. By eliminating mortar from the roof you can virtually eliminate any such maintenance. Allowing the natural movement within a roof structure to take place without damaging the ridge and hip fixings. This provides the means to 'mechanically' fix ridges and hip tiles, greatly reducing the risk of storm damage.
Dry Ridge systems come in a variety of designs but offer a similar level of performance. They are designed to secure the ridge tiles which are located at the apex of a roof.
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.
Dry Verge & Dry Ridge Systems, when properly fitted, will last longer and require very little maintenance than the mortar fixtures.
