Dry Fix is a method of mechanically fixing Ridge and Hip and Verge. As well as additional components such as valley troughs and bonding strips, which traditionally have been fixed with mortar. The majority of roofs in the UK are now completed using Dry Fix components, including new builds, re-roofing and refurbishment projects.
As a flexible solution, Dry Fix can be used with most concrete, slate and clay pitched roof products.
BS 5250 (The Control of Condensation in Buildings) outlines the requirements and specification of ventilation in the roofspace to control the build-up of possible condensation. This often happens during the drying out process (after completion of the building) or during periods of wide temperature movement. Ventilated dry ridge products provide a continuous air gap (to BS 5250), allowing for air movement within the roofspace and avoiding pockets of still, moist air, which might cause condensation to build up.
You can use Dry Fix components for the ridge, verge, hip, valley and bonding details.
Dry Fix meets the requirement of BS 8612 for performance, BS 5534 for mechanical fixing (Code of Practice for Slating and Tiling) and BS 5250 for roofspace ventilation (The Control of Condensation in Buildings). It is an established method of fixing and has been used for many years in the construction industry.
