Dry Ridge Roofing in Hull

Why mortar on the ridge eventually lets go

Traditionally, the ridge tiles along the top of a roof and the tiles at the verges were bedded in sand and cement. Mortar does not move with the roof. Over years of frost, sun and wind it cracks, comes away in chunks and leaves the ridge tiles loose, which is a common reason for them lifting in a storm. A dry ridge system takes that weak point out of the roof.

Instead of mortar, each ridge tile is clipped or screwed down to a ridge batten, over a roll of breathable material that seals the joint against rain. Dry verge works the same way at the gable edge, with interlocking caps fixed to the ends of the tile battens. Nothing relies on bedding, so there is no mortar to repoint and far less to work loose in high wind.

Dry ridge is the right call when the mortar has failed along most of the ridge, when the roof is being re-tiled, or when you are tired of patching the same joints. The ridge roll also lets air escape from the top of the roof space, which helps with ventilation. We confirm the system suits your tiles before quoting, because not every older tile profile takes one.
