Dry Ridge Systems Across Bucks, Berks & Herts

Older mortar-bedded ridges may rely on the mortar bed; other installations also use mechanical fixings. Mortar is strong when new, but sun, frost and roof movement gradually weaken it. That is why mortar ridges eventually need repointing or rebedding.

A dry ridge system replaces the mortar with a mechanical fixing. A timber ridge batten is fixed along the top of the roof on adjustable brackets. A breathable roll is laid over the batten and dressed onto the tiles either side. Each ridge tile is then screwed or clipped to the batten, with union clips at the joints to keep them aligned and sealed.

Because there is no mortar to crack, maintenance is lower. The breathable roll also allows air to move through the top of the roof, helping to reduce condensation in the loft. Dry ridge systems are now widely used on new roofs and are a common upgrade when an existing mortar ridge has failed.

Components must suit your tile profile, so we check this during the inspection and explain exactly what will be fitted before any work starts.

Dry ridge is not always the right answer. On some period properties, a traditional mortar finish suits the look of the house better, and where tiles are an unusual profile, compatible components may be limited. We weigh these points up with you during the inspection.

When fitted during a full roof replacement, dry ridge integrates with the new membrane and battens. When fitted to an existing roof, we lift the old ridge, clean off the mortar, and reuse sound ridge tiles where possible to keep the finish consistent with the rest of the roof.
