A dry ridge system is the method of mechanically fixing ridge tiles to the ridge of a roof without the use of mortar.  The unions secure the tiles together with a small expansion gap while the clamps are placed between tiles and screwed down into ridge board or batten. This provides a windproof fixing that will ensure no tiles come loose over time, accounting for natural expansion, contraction or any other type of roof movement. Fitting a dry fix system can be done regardless of what the weather is doing at the time. Once fully installed, the top of the roof will look very similar from street level to how it would if bonded with mortar. However, unlike mortar bonded ridge tiles, a dry ridge system should not require regular (and often unsafe) trips up to the roof to assess and maintain loose or missing ridge tiles.
