1. Grow a roof gardenOne of the best ways to keep the roof cool is by growing your own rooftop garden with green grass and potted plants. The green roof shades the building from direct sunlight while the mud within the potted plants and the lawn absorbs most of the heat that hits the roof. Before going for a roof garden, make sure that the roof is properly waterproofed so as to prevent any type of water seepage through the external walls or roof slab, which may cause damage to the building.
In this example the outdoor tiles are laid at an angle to create a dynamic-looking set of pathways within the green lawn.Note: There is more tile wastage in creating organic, curved or angular floor designs in comparison to straight-line floor designs.
