All gable ends have a weak point between the tiles and the top of the wall. This is called the verge and it has conventionally been mortared. These mortared verges are now becoming obsolete because they pose 2 long term problems:
a)  As mortar is a porous material and subject to expansion through freeze/thaw action, mortared verges deteriorate and crack, and require regular maintenance.
b)  The pieces of timber that tiles fix onto have their ends located in this mortar. With the mortar being regularly damp these timber lath ends nearly always become rotten.

The answer to this problem is to invest in having a dry verge system installed, which principally involves specialist UPVC caps being fitted around the edge tiles and providing a waterproof seal to this vulnerable part of the roof. If fitted correctly, this will give you an attractive finish which will need no further maintenance.

Installation the Aquaseal Way

Unfortunately, dry verge has become one of the favourite crafts of rogue traders, who may travel the streets posting cheap prices through your letterbox. This has resulted in a great deal of dry verge systems throughout the UK being inadequately fixed, and subject to movement or being completely blown off during high winds.

At Aquaseal, we realise fully that the correct fixing of this system is all important. We use a unique timber lath system to fix the verge to give the installation maximum strength, which may be fixed inside the verge, underneath the cloaking, or onto the bargeboards underneath, depending on the particular dimensions of your verge as all are slightly different. Our installation will also include splicing any rotten tiling battens, and taking care of any rotted felt. All our dry verge installations carry a rock solid guarantee, and are available in either tile grey or brown.
