Benefits of Dry Fixing over Traditional Mortar

Over the years systems have been developed to do away with the need for Mortar (Cement) on Roofs. This is refered to as Dry Roofing or Dry Fixing. The areas on a roof that are usually fixed with using mortar are the verges (gables), ridges, hips and valleys. The most common dry fix products are manufactured using either aluminum. PVC, steel, screws or clamps.

Why avoid Mortar?

Mortar has been the traditional method for fixing roof systems such as verges, ridges and valleys for many years.

Disadvantages of Mortar on a roof:

• Time consuming for roofer during installation
• Limited lifespan
• Requires regular maintenance
• Will crack and fall out
• Leaves roof exposed after it falls out
• Doesn’t provide adequate protection against wind uplift
• Susceptible to water ingress and penetration

Why use a Dry Fix Method?

Regulations (BS5534) now state that all Verges, Ridges, Valleys and Hips must be fixed using at least one method of Mechanical or Dry Fixing. Dry Fixing has a huge number of advantages over traditional mortar.
