If you have a gable roof and live in an older style property, the chances are that you have a ‘wet verge’. The ‘verge’ refers to the outer ends of your roof above the gable end (the wall above which two verges meet). Traditionally, these areas at the edge of your roof are fixed with mortar in order to prevent water ingress and pests such as birds nesting in your roof. Roofs rendered with mortar for these purposes are what we refer to as ‘wet verges’.


The mortar does the job it’s built for; it stops pests getting into your roof and will stop water leaking through too. The real problem with mortar lies in its durability. Mortar naturally deteriorates over time due to weathering caused by facing the elements and the natural movement within a building structure, which can dislodge the mortar. This leads to cracks in the mortar which can lead to the problems it’s meant to prevent. It can also leave your home looking quite unsightly.

Mortar is an old way of doing this job, ‘Dry fixing’ is an increasingly popular roofing option which allows for the weather and pest-proofing of your roof without the need for mortar.

Dry verge system roofing makes use of interlocking caps that fit over the edge of your roof tiles, and offers an effective and, more importantly, durable alternative to wet verges.
