Roofs are proving to be one of the most effective shields from the high cost of energy that's needed to keep our homes comfortable. In the past, roofs may simply have been a way to keep out the rain. However, studies have shown that they also play a critical role in the overall energy efficiency of the house.
However, not all roofs perform the same when it comes to energy savings. Some types of residential roofing are more effective at regulating internal temperatures. What are some of the best options in the market today?
Slate tiles have been used on roofs for hundreds of years. This is because slate is a cool roofing material that's quite effective at keeping temperatures in the house cool even in regions with hot climates. The aesthetics of the material are also a key selling point, and many people even prefer the look of slate tiles as they wear.
However, it costs quite a bit to install slate tiles due to their weight and low availability in certain regions.
Clay tiles offer an alternative solution for those who can't go for slate tiles. These tiles can even be colored to mimic the look of slate. The light color of basic clay tiles means that they don't retain so much heat. The tiles are also modeled into shapes that are easy to install and allow for easy circulation of air and drainage of water.
Just like slate, the weight of clay tiles should be considered, and standard houses can't support this weight without reinforcement. Some tiles can also snap in very cold weather.
Metal roofs are an excellent option for both hot and cold weather. In cold weather, metal can stand up to heavy snow and strong winds. The material also prevents the formation of dangerous icicles, and heating cables can be easily installed.
In areas with hot weather, metal roofs can be installed with reflective coatings that will reduce the amount of heat entering the house.
Cement tiles offer an affordable option to slate and clay tiles, although they still cost more than asphalt shingles. The weight of the concrete makes it highly weather resistant, enabling it to withstand snow and keep out heat. These tiles are even more effective when they're dyed using cool colors. These tiles are also highly durable with some examples surviving for well over 100 years.
