Dry Ridge Systems

At JAR Roofing Ltd we have over 25 years of experience in installing high quality, durable and weatherproof Fascias and Soffits.

Dry ridge refers to a method of mechanically fixing ridge tiles or hip ridge tiles to a roof without the use of traditional sand and cement mortar.

Dry ridge, rather than relying on mortar for a bond, instead employs a dry fix system that typically uses screws – often stainless steel – to attach clamps between the joints of every ridge tile, clamping them to the roof. Beneath these screws are waterproof unions that catch any small amount of direct rainfall and disperse it sideways back onto the roof itself.

The benefits of a dry ridge system are as follows.

Will not blow off

There are many things that can affect the lifespan or bond of mortar bonded ridge tiles. Dry ridge however (as long as it has been installed correctly) will not blow off under normal conditions, greatly reducing the risk from storm damage. No more ridge tiles landing on the floor, car or conservatory after high winds.


Unlike mortar there is nothing to maintain, mortar mixes will degrade over time, sometimes prematurely.


Dry ridge provides discreet ventilation of the roof space and helps to stop any harmful buildup of condensation, as described on my roof ventilation page.


Roofs can actually move through vibration (near main roads or train tracks) or through natural expansion and contraction. Dry ridge allows for all types of movement.
