Dry Ridge Roofing vs Mortar

Posted on 05 July, 2021

In the ever-changing modern world, it’s a well-known fact that all good things must come to an end.  Technology gets smarter, procedures get faster and innovation becomes groundbreaking. New techniques pave the way for a better, more efficient future and this is no different when it comes to the world of roofing.  In August 2014, new regulations stipulated that all roofs had to be fully compliant with the new BS5534 code of practice, coming into full effect as of February 2015, giving current builds a 6-month breather.  This involved changes to batten selection, fixings and amongst other things deemed mortar alone to be an insufficient way of fixing ridges and hips, these must now be mechanically fixed.  This is where dry ridge roofing comes in.

What is Dry Ridge Roofing

In a nutshell, dry ridge roofing is the process of mechanically fixing (with screws or other fasteners) ridge tiles to a roof without the use of mortar.  Over the last few years, roofing techniques have most definitely evolved for the greater good. This new method of dry ridge roofing has been proven to be more resilient in extreme weather conditions which appear to be on the up in the UK, according to the increased number of weather-related insurance claims resulting in mortar damage.

So how does dry ridge roofing work?  Well, this way the tiles are screwed directly onto specially treated timber which runs the full length of the ridge tree, therefore acting as an enforcement to the original mainframe.  A waterproof membrane is then laid, followed by the new tiles, which are then fixed in place with stainless steel connectors for added protection. For more information, see our guide on dry verge installation.

Dry Ridge Roofing vs Mortar 

Traditional mortar roofing involves mixing sand, cement and water in the perfect ratio to create an adhesive to fix the roof tiles in place.  This, of course, leaves people wide open to less than honest roofers shall we say, using a weaker mixture, which of course reduces the lifespan of the roof tiles.  This is not possible with dry ridge roofing as the tiles are all fixed in the same way, therefore once they are in place, they are there to stay. Some old school roofers may argue that the new tiles may become brittle in time, however, there is no evidence to support this.  Whereas with all the will in the world it’s inevitable that mortar will naturally weather and break away not to mention become porous, causing it to swell and ultimately crack, not ideal when the weather turns and the wind gets underneath.

Benefits of Dry Ridge Roofing

It’s safe to say that traditional mortar will soon become a thing of the past, but with the benefits of dry ridge roofing far outweighing those of mortar, we can’t say we are complaining!  Some of these benefits include:

  • Maintenance-free for an estimated 50 years (following installation from approved companies)
  • It’s long term cost-effective as there will be minimal repairs required if any.
  • No need to be repointed, saving time and money.
  • Its fuss-free installation makes it quicker and easier than mortar when following the appropriate guidelines.
  • It gives a much neater finish, therefore, more aesthetically pleasing.
  • A breathable membrane below the tiles means less damage caused by condensation or water retention.
  • It’s been tried and tested in many conditions and can withstand high wind speeds up to 100mph. 
  • It can be installed in all weathers and is UV stabilised.
