Why Should I Build Replace Or Restore A Parapet Roof
With storm season approaching in Brisbane, parapet roofs are a great option due to their ability to catch debris and prevent damage from loose tiles falling from your roof. It also makes it easier to clean your roof after rain or a storm, as debris will have collected towards the lowest point of the slope.
Parapet roofs can also prevent damage from high pressure winds. When wind blows against a building it produces vortices at the roof edges that create huge pressure differences at roof perimeters that can suck roofs off buildings. A parapet roof, however, can guard you against hazards like these by reducing the pressure from these winds.
