If you live in a hot climate, then you should at least consider how the various materials you use in your home will contribute to keeping your home cool. Nowhere is this more important with your roof, which takes the constant assault of the sun's rays all day long. One solution for keeping your roof cool is to use clay tile roofing.
What Type of Clay Tiles Should You Use?
There are a lot of different shapes of clay tiles. If you really want to keep your home cool, you need to go with S-shaped clay tiles. Every S-shaped tile will have a valley and a ridge just as would be the case if you laid an S over on its side. As it turns out, the ridge is the most important feature when it comes to keeping your home cool.
How Clay Tiles Keep Your Home Cool
The first thing you should look for in clay tiles is whether they have a reflective coating or not. If they do have a reflective coating, it will deflect some of the sun's energy away from your home before it has a chance to contribute to heat gain in your home. On the other hand, whether your tiles have a reflective coating or not, they will heat up, and this is where the shape of your tiles becomes critical.
As your tiles heat up, the heat from the tiles will settle into the channel between the ridge in your tile and the roof deck. The hot air will then rise up your roof and escape through a special vent in the ridge line. The problem with roofing that lays flat against your roof is that there is nowhere for the heat to go, so it transfers through the decking into the interior of your home. S-shaped clay tiles correct this problem by giving heat an exit strategy.
Clay tiles do not look at home on any roof, so they might not be the right choice for every home. They are also brittle, so you need to be careful about walking on them, and you need to prevent limbs and other objects from falling on them. That being said, if you are looking for a low-tech way to help keep your home cool, clay tiles definitely fit the bill. Thus, they are a great choice for hot climates that do not see a lot of adverse weather.Share
