Dry Systems

What is dry roofing?

Dry roofing is the method of mechanically fixing products and systems to the roof perimeter without the use of sand and cement mortar. The many advantages of dry roofing highlight why it has been well established in Scotland for some time and now leading the way throughout the rest of the UK and Ireland. Dry Roofing is much more advantageous than the older system of using mortar as a fixing solution.  We still do roof verge repairs and re-bed ridge tiles using mortar but dry roofing products are more secure, weatherproof, longer lasting and help keep birds and other creatures from gaining access to the roofspace where they may cause other problems.

All our dry roofing systems come with a guarantee.

Traditional mortar bedding is quickly becoming a thing of the past, with dry roofing replacing it as the norm for multiple applications above the roofline from ridge and hip systems to valley trough installation.

The move towards dry fix products has been accelerated by the large percentage of claims in relation to mortar and its potential to fail, even on new buildings. Mortar has a limited lifespan and requires maintenance as it will deteriorate in time through natural weathering. It is also susceptible to cracking because of the natural movement in the building structure and shrinkage. This can leave the ridge & hip tiles and verges vulnerable to the elements, which can then become dislodged by high winds and strong winds causing additional damage and water ingress and costly internal damage.

Our tried-and-tested Roll-Out Dry Ridge solution is a mechanically fitted system which securely fixes the ridge tiles onto a roof, protecting them from wind up-lift and rain penetration.


The number of storms battering the UK every year is increasing - and with this there's a growing revalation of the unreliability of using mortar to secure vulnerable areas of the roof such as the verge of the roof.

Here at JBK Roofing Services, we can fit a Fast Fit Dry Verge System has been designed to provide an extremely cost effective alternative that avoids all of the long term maintenance problems - and costs - associated with mortar bedding.

Why not upgrade from older roof products like cement, to UPVC Strong Plastic ridge and verge systems.

There are many benefits to upgrading, one of the major reasons is to prevent the ingress of pests and birds into the loft space.

We do provide a roof verge repair service and also re-bed or replace ridge tiles. Roof verges and ridge tiles do need more maintenance than the new dry roofing systems.  The weather takes a toll on the mortar which secures the ridge tiles and protects the edge of the roof (verge).  Over time, the mortar will crack, and crumble allowing the ridge tiles to loosen; birds also take advantage of crumbling mortar and nest or gain access to the roof space.  This also allows the rain water access the roof space, which again will cause damage.

New Dry Systems, Ridge and Verge, replacements will cut down the costs of future repairs.
