Things are changing however. Over the past 10 years we have seen new houses in the upper price range sprouting parapets as part of the gentrification of styles.

In addition, the gable walls and, in some instances, the party walls between the houses, have started to project above the line of the adjacent roof. It all looks very attractive but, unfortunately, these walls all need careful attention to detail to avoid future problems.

A normal house wall is only subjected to the weather from one side. With a parapet wall, however, it is exposed to rain, sun and frost from both sides.

So what? Well, brickwork constantly expands and contracts. This is caused by temperature and moisture. The surface temperature of an outside wall can vary from as high as 30 degrees plus to as low as minus 5.
