Re-pointing

Re-pointing addresses the visible mortar joints between individual ridge caps along the apex and hips of a tile roof. Over the years, the original sand-cement pointing mortar dries out, shrinks, and cracks due to constant thermal expansion and contraction, rain exposure, and UV degradation. Once these joints crack, water can penetrate into the roof space beneath the ridge line — a common but often undetected source of roof leaks. Modern re-pointing uses flexible polymer-modified compounds rather than traditional sand-cement mortar. Products such as Dulux Acratex Flexpoint are specifically designed to accommodate the ongoing thermal movement of the ridge caps without cracking. The flexible compound is applied with a caulking gun or trowel into the cleaned-out joints, and it cures to form a durable, elastic seal that moves with the tiles rather than cracking away from them. In Gippsland, re-pointing is one of the most frequently performed roof maintenance tasks, particularly on homes built from the 1960s to 1990s when cement tile roofs were standard. Town & Country Roofing includes re-pointing as a standard component of every roof restoration, and it can also be performed as a standalone service for roofs that are otherwise in good condition but have deteriorated pointing. Re-pointing is always paired with re-bedding, as there is little value in re-pointing over failed bedding mortar.
