We have recently visited a property which is less than 10 years old to Survey in Caterham-on-the-Hill. We noted typical parapet wall detailing defects. Due to be lack of damp proof courses beneath the coping stones, there is deteriorating mortar and water penetration internally. Even modern houses can have poor detailing and defects manifesting themselves within a few years. Also if loose coping stones should fall this could cause damage to vehicles or worse if they hit somebody.
