Dry Ridge

Dry Ridge systems come in a variety of designs but offer a similar level of performance. 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.

Dry Verge

Dry Verge

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, ie 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.

A dry verge system will also reduce the risk of wind damage, water penetration and will stop small animals getting into the roof space.

Dry Verge

The ever changeable weather takes its toll on the mortar based roof verges.

The mortar secures the gable tiles.  Over time, the weather causes the mortar to crack and crumble and requires regular maintenance. Birds also take advantage, nesting or shielding in the verges which causes more damage and they may access the roof space. 

Dry verge systems have proved extremely popular and many properties have the new reliable dry verge installed to replace the older mortar type fixings.

Dry verge offers more protection, it's weatherproof, more secure, keeps birds and other things from gaining access to the roof space and is a cost effective alternative to mortar that avoids all the long term maintenance problems.

Use of mortar

Whilst mortar certainly does the job, there are a number of disadvantages it is worth being aware of.

First, mortar has a limited lifespan and requires regular maintenance because it will deteriorate in time through natural weathering.

Secondly mortar is susceptible to cracking because of the natural movement within the building structure, particularly where the roof passes over solid masonry walls. Once this happens, the ridges, hips or verges can become dislodged by high winds, and will be susceptible to water ingress.  We do provide a repair service for roof verges and re-bed ridge tiles and re-mortar.  We also install dry verge and dry ridge systems which have many advantages over the mortar systems.
