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 interface with the ridges and the tiles can be handled in two ways.
The first method uses plastic inserts following the shape of the tiles, the second uses an adhesive roll which is corrugated and stuck down to the tile surface. Whilst the 'roll' systems are the most affordable, the profile system looks the best and offers an edge when it comes to longevity.
