Jones's Property Maintenance...

Removed all the old ridge tiles and cleaned the ridge removing all the old mortar.

Replaced with the dry ridge system, which is much more durable and cost effective in the long term.


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.

The dry ridge roofing system does not need the mortar, it is a mechanically fixed system which is much more durable, is stronger and requires little maintenance.



Dry Verge Systems

Jones's Property Maintenance...

Installs dry verge systems help avoid these defects and the need for periodic maintenance of the mortar bedding. For many tiles, special 'cloaked verge' tiles are available which neatly close the gap at the verge.

Alternatively plastic dry verge systems are available which suit most tiles. These are available in single units, i.e. one piece per tile course, or in continuous lengths. These are attractive and highly functional ways to improving the overall appearance of your roof. The systems are easy-to-use and provide a neat, secure and mortar-less finish at roof verges.

Dry Fix Benefits

Dry fix systems allows for the natural movement within a roof structure to take place without damaging the ridge and hip fixings.

It provides the means to 'mechanically' fix ridges and hip tiles, greatly reducing the risk of storm damage.

A channel is fitted inside the ridge to allow for any rain to be dispersed back to the roof.

Weather proof and waterproof

Extremely durable

Provides discreet roof space ventilation at the ridge and hip which helps control harmful condensation in the roof space.

Allows the roofer to complete the work safe in the knowledge that rain will not cause mortar to stain the roof or frost to damage the mortar before it has had chance to properly set.

More cost effective than the mortar system.  

The cost of dry fix v mortar

This is not any easy question to answer as there are many systems on the market, plus a large proportion of the cost of both mortar bedding and dry systems is in the labour.  As a general rule the cost of the dry system per linear metre of ridge or hip will be slightly more than the cost of mortar.


However, while the cost of repairing the mortar is cheaper in the short term, the dry roofing is much more durable in the long term.  Mortar needs checking and replacing regularly while the dry fix systems will last for years.
