Did I mention that the front parapet was badly crumbling<\/a>? If you wonder why, the answer is easy: bulk water infiltration into the masonry.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

The cornice roof (a copper sheet) was supposed to shed water away from the building. Not only did the cornice roof come apart at the seams, it had bent inwards, allowing water to pond right behind the edge. To \u201csolve\u201d that problem, a previous owner had punched small drain holes into the copper sheet, allowing ponding water to enter the cornice interior and the masonry behind.<\/p>\n\n\n\n

Some of that masonry had deteriorated so badly that someone put a layer of cement parging across it to prevent it from falling off. That, however, further aggravated the problem, because the cement parging trapped moisture and prevented the masonry from drying out.<\/p>\n\n\n\n
