    Roof Treatment

    Generally the garage has nothing on top of it so it is directly exposed to the sunlight which can make it hot quicker than the rest of the house. There are several treatments that can be done in order to cool it down. One of the basic treatments is to coat the outer part of the roof with white paint. The heat absorption will automatically reduce. Similarly, you can also get insulating tiles installed on the outer part of the roof to stop the heat from entering the garage. It will cost a touch more but it is a long term solution.
