Dry Ridge Roofing across Greater London

On many older roofs the ridge tiles are held on by mortar alone. Over time, frost, movement and weather crack the bedding, ridge tiles loosen, and in strong winds they can lift off entirely. Water also finds its way in through the gaps. A dry ridge system replaces that mortar with a mechanical fixing: each ridge tile is screwed or clipped down to a continuous ridge batten or a fixing bracket, and a weatherproof roll seals the joint underneath. The ridge stays firmly in place and does not need repointing.

BS 5534, the British Standard for slating and tiling, was revised in 2014 to require ridge and hip tiles to be mechanically fixed, with mortar no longer relied on alone. Dry systems are one of the most common ways of meeting that standard, and many include ventilation at the ridge to help the roof space breathe. Ashlar Roofing fits dry ridge and dry hip systems on tiled and slate roofs, along with dry verge units on gable edges where the old mortar verge has failed, on new roofs and existing ones.
