The fact is that it doesn’t; it doesn’t make house hotter. It doesn’t make house hotter. But it does. Not always.
Roofs aren’t usually the issue, more often than not, the humidity is. This is a fairly common problem in the Southeast, and the humidity in the region is often directly related to the amount of rainfall. High temperature and humidity levels rise with rainfall, but low temperatures cause less humidity. So the more you have, the less humidity you can have.
I’m sure a majority of you are tired of hearing me say this, but it’s true. I’m sure you’ve heard this one before. Houses in the Southeast are often “hotter” than houses in the Midwest. This is mostly due to the humidity. I’ll explain. The average Southeast house has a roof covering 90% of its roof surface, in the Midwest it would only cover 70%.
When the humidity falls, so does the temperature. Less humidity means less heat and more cool air. So the closer you can get the house to your body, the lower the heat and the lower the cool air level.
This is true. In the winter, the Southeast is often hotter than the Midwest. In the summer, the Midwest is often hotter than the Southeast. In the fall, the Southeast is usually hotter than the Midwest. In the spring, the Midwest is usually hotter than the Southeast. And in the fall, the Southeast is usually hotter than the Midwest. I can’t say I have a huge problem with this. Just make sure you have a good air conditioning system in your house.
Another reason for not having air conditioning in your home is that most people don’t. And if they do, they don’t do it in the summer or fall, because they just want to live in a house. If you do have air conditioning in your house, you should be able to lower the temperature in your house by keeping the airflow going through the vents and increasing the cool air level.
I think I have a good solution for high heat and humidity in the summer, especially in the fall. In my case, I install a system similar to what the original poster suggested. The idea is to install a dehumidifier in the kitchen. I use a small hand pump in the kitchen (like this one here) and fill the air with water and ice cubes. This creates a cool moist air flow that helps to lower the heat in my house.
I guess the question is why not? This post is just a quick primer of how to lower the heat in your house to lower the temperature. For the most part of the year I keep my house in constant summer mode with an air conditioner. This keeps my house from getting too hot and keeps it’s cool by the way.
Roofs don’t actually do much good, because they don’t actually reduce the amount of heat trapped by your house. In fact, they may actually increase your heat. What they do is create a positive pressure where there is none, which causes the air to move faster through the roof and thus to reduce the heat in your house. But in addition to the heat reduction that comes from the roof, they also create a positive pressure on the outside of your house.
The cool thing about the positive pressure that the roof creates is that it creates a cool breeze which keeps the air moving through the roof. This is a great trick for cooling your house as long as you don’t have any windows. As you open up the shade for the cool breeze to enter the house, then you will have more heat escaping through your windows.
