Hi The cost can vary due to a couple of issues. 1. Does the over-hang of the tile need to be adjusted to accommodate the dry verge? 2. Are the batten ends sound and free from rot so that they can be fixed properly? 3. Is the old mortar and under cloak to be removed? (dry verge are often fitted by screwing or hammering straight into the old mortar on the gable. AVOID THIS!!) As a rough estimate, on a straight forward installation with all mortar removed and units fitted to battens, for the 22 dry-verge i would charge around £250 - £300. Accurate prices are hard because of factors such as conservatories below and things. Hope this helps and good luck. Matt
