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.
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.
