What to do if it's hot at night when living on the rooftop

There are many families who live on the top floor. They feel very hot on summer nights. This is because the top floor is closest to the sky, so when the roof is heated by the sun, it makes the house very stuffy. At this time, just opening the windows for ventilation is useless, so you need to find a way to do some work on the roof, such as sprinkling water on the roof or planting some flowers and plants. Let’s take a look at what to do if it’s hot at night when living on the roof?

A layer of black sunshade cloth is spread above the roof. There is a certain distance between the sunshade and the roof. The sunshade cloth must be fixed firmly, otherwise it will be blown away by the wind.

The ceiling on the third floor does not need to be very gorgeous. The purpose of a suspended ceiling is to create a distance from the ceiling so that the room will not be very hot.

On the roof of the third floor, you can grow some flowers and plants, and also vegetables. You can get some soil and plant some plants. However, we need to see whether the roof can withstand the gravity of plants and soil.

Sprinkle water on the roof in the afternoon and evening to ensure that all surfaces are covered with water. The evaporation of water can carry heat. If you want it to be effective, you need a lot of water.

Build a heat-insulating layer on the roof so that the sun cannot directly hit the roof. This method has always been recognized by everyone, but the cost is not cheap, and the subsequent maintenance is also a problem. Moreover, once the insulation layer is completed, it will be impossible to walk on it.

Use materials such as steel plates to build a sunshade directly on the roof. This solves the insulation problem and allows people to walk under the sunshade. However, make sure the awning is secure. Awnings generally don’t cost a lot of money.

Precautions

First, the specific choice should be based on your actual situation.

1. Sprinkling water on the roof: Connect the installed faucet to the roof, spray it on the floor, and cover the entire floor to effectively remove the heat that penetrates into the room.

2. Laying an insulation layer: Air circulation can take away heat, so an insulation layer can be laid on the roof. When sunlight shines directly on the insulation layer, the increased temperature can be conducted away through the air between the roof and the insulation layer, preventing the top floor ceiling from heating up rapidly. This is a traditional and effective insulation method.

3. Build a sunshade: Since the laying of the insulation layer affects the residents' activities on the roof, and if the quality of the insulation layer is not good, it will be difficult to repair and affect the appearance. Therefore, sunshade insulation has become popular in recent years.

4. Install light-absorbing or light-reflecting devices: convert the sunlight hitting the roof into electrical energy or reflect it away. If conditions permit, you can install solar panels to generate electricity using sunlight. If it is not suitable to use solar energy, a mirror reflection array can be set up on the roof. Glass, thin stainless steel plates, tin foil plates, etc. are all good reflective materials.
