Ridge with tileline ridgeroll ventilation

This system is suitable for all Dreadnought ridge tiles except capped angle ridges and is quick and easy to install.   It is now mandatory, with the introduction of the new British Standard BS 5534,  to mechanically fix all ridge tiles whether they are used on the ridge or or the hip line.  The ridgeroll product comes in 6m boxes and consists of a corrugated grey coated aluminium roll which is laid out centrally on the ridge and temporarily fixed with double-sided adhesive tape. The ridge tiles are then laid over the top securing the roll in place leaving 10mm joints between each ridge. A cleat is then placed over the joint between the ridge tiles and screwed down into the ridge board.

For ornamental ridges, a butterfly clip is used to attach on to the ridge tiles and provide a fixing that can be screwed into the roof timber
