The old wet verge system needs periodic maintenance of the mortar bedding. Traditionally mortar was used to keep out water and pests, such as small animals or birds. Although this is a more cheaper and practical, mortar is not very durable and, over time the mortar will crumble and crack due to the changeable weather of our climate and also natural movement of the property. When the mortar cracks this causes problems with the rain getting in, also birds are known to penetrate the mortar and make themselves a nice spot for nesting. Birds can also bring other pests into the roofing area causing havoc. Therefore, regular checking of the mortar is essential to avoid problems. Mortar may not be an easy fix, as scaffolding may need to be erected and the job is time consuming so it may not be cost effective in the long run.
The new Dry verge systems help avoid the defects of cracking and crumbling mortar and the pests and bird problems associated with it, as well as the need for regular maintenance of the mortar bedding.
