Luckily nowadays, there are plenty of low-tech and low-cost remedies to keep the extra heat at bay.

Beyond its charm, growing a roof garden or “green roof” has a practical value. The greenery with all the soil, grass, and plants help shade the building from direct sunlight. It helps both in reducing heat loss and heat absorption, making it a perfect choice for houses in either hot or cold climates.

Furthermore, green roofs help minimize what has been referred to as the “heat island effect.” This is when the temperature in urban areas increases due to the sun baking the asphalt and metal surfaces.

Though this type of roofing is certainly not that popular, there has been a growing trend among environmentally-conscious homeowners living in hot-weather regions.

Keep in mind that before going for a roof garden, you ensure that your roof is waterproofed to avoid any water from seeping through your interior, damaging your home’s structure.

2. Play with Paint

You can also reduce the heat gain in your roof by turning it into a reflective surface.

You might want to consider painting the concrete surface of your roof with cool paint colors. Lighter colors provide good thermal insulation. They help reflect the sun’s rays, keeping your indoor home cool.

Installing white ceramic or porcelain tiles is also an excellent choice if you want a more permanent solution to deal with the heat.
