Dry Ridge & Dry Verge System Installation
Mortar-bedded ridge tiles are no longer compliant under BS 5534 and tend to lift in Chiltern winds. Dry ridge fixes it mechanically — the only spec we'll quote on a reroof.

- BS 5534 compliant fixings
- Replaces failing mortar ridge
- Continuous high-level ventilation
- Plain tile, profiled tile & slate compatible
- Manley & Klober systems
- Dry verge to match
What changed in BS 5534
Since 2015, ridge tiles must be mechanically fixed — mortar alone is no longer compliant. Roofs reroofed before then are coming up for ridge work now, and dry ridge is the only spec that meets the standard.
How a dry ridge actually works
A breather roll seats over the ridge tile join, a continuous batten sits along the apex, and each ridge tile is mechanically fixed with a stainless screw and gasket clamp — plus the high-level ventilation BS 5250 now requires.
FAQs
Can I retrofit dry ridge without a full reroof?+
Yes — we strip the existing mortar ridge tiles, fit the dry ridge system underneath and reuse the original tiles if sound. Typically £900–£1,800 for a semi.
Does dry ridge look different from outside?+
No — the ridge tiles look the same from ground level. Only difference is a small gap line under the tile where ventilation enters.
