Dry Roof Systems
Today's roofs need to be weatherproof, look good and provide adequate ventilation. This system provides minimal on-going maintenance but maximum durability and long life.
Dry fix roofing is the term used to describe the mechanical fixing of the roof perimeter at the ridge, hip and verge without the use of mortar.
Traditional mortar bedding is still the most widely used fixing method in England and Wales. However, the increased incidence of storms over the last few years has clearly highlighted the unreliability of mortar. the gradual switch to dry fix roofing in Britain looks set to gather great momentum and considering all of the advantages, it is not difficult to see why.
Why use Dry Fix Roof Systems?
The roof is the most exposed part of any building. Using mortar to secure vulnerable areas of the roof, such as the verge and ridge, will inevitably lead to future maintenance. Differential movement causes the mortar to crack and no reliance should be placed on its tensile strength. The action of frost and rain will exploit the development of hairline cracks caused by these movements.
In contrast, because dry fixing is mechanically fixed:
- It is safe and secure, and offers better resistance to wind uplift and water penetration
- Dry fix products can be installed in damp and frosty conditions
- It is highly cost effective and has a more consistent appearance with no long term maintenance problems and costs associated to mortar bedding'
