Dry fix is a method of mechanically fixing roof ridges, hips, verges and valleys while avoiding the use of mortar. Dry fix products can be used on pitched roof products such as concrete, slate and clay.
They are suitable for both new builds and refurbishment projects. Eliminating the need for bonding agents, such as mortar, components are fitted with a mortar free method and mechanical fixing application, which can be joined directly to the roof structure.
HOW DOES DRY FIX APPLY TO OUR RIDGE KIT?
Dry fix ridge systems involve covering the roof batten with a breathable ridge roll. Our ridge roll is manufactured in-house from a polypropylene hydrophobic mesh that allows the roof to breathe whilst repelling water. A pumped butyl self-adhesive strip then allows for a secure adhesion to the tile or slate. One by one, the ridge tiles are then installed over the ventilation ridge roll to secure it in place and are laid across the apex of the roof using plastic unions, ratchet clips, screws and nails. The system conforms to British standards and creates a neat and aesthetically pleasing ridge line.
HOW DOES DRY FIX APPLY TO OUR HIP KIT?
Ridge and hip tiles run across the peak of the roof, providing the perfect clean finish to a roof, so it is important that they are installed securely. The dry hip and ridge system simply involves fixing ridge tiles to a roof without sand or cement mortar, but instead with screws and ratchet clips, which fix each ridge tile to the roof. To be used in conjunction with our Ridge Kits, our Hip Kits contain everything you need to fit a 6m hip.
HOW DOES DRY FIX APPLY TO OUR VERGE SYSTEM?
Dry fix systems solve the problem of mortar failure but will only work well if the components are reliable and high quality. Our verge units and ridge caps are manufactured in-house from polypropylene for superior flexibility and ease of installation. Badly designed verge units can often prevent water from draining away from the walls, resulting in failures including staining to gable ends of buildings. Our verge units are designed to conform with BS 8612, so you can be confident that they provide a reliable, high-quality solution to ensure weathertightness and durability in pitched roofs. Our durable plastic verge units and ridge caps require very little maintenance in comparison with mortar whilst eliminating leaking roofs and infestation from animals & insects .
THE BENEFITS OF DRY FIX
For many years, mortar has been the traditional method for fixing roof systems such as verges, hips and ridges. Regulations (BS 5534) now state that these must now be fixed using at least one method of mechanical or dry fixing. So what are the disadvantages & advantages of dry fixing versus traditional mortar:
