Energy efficiency is a very important requirement that modern roofing materials need to fulfil – the level of energy savings offered by modern roofs is an important aspect not only for allowing the roof owner to save on the energy necessary for heating and cooling the building interior, but also for protecting our natural environment and for reducing the environmental impact of the building. Here are a few important details provided by experienced roofing company Houston TX contractors about the energy efficiency offered by different roofing materials.
Clay and Cement Tiles
Clay and cement are great insulators, the roofing tiles made from these two materials also being great, energy efficient solutions. The roofing tiles made from clay or cement provide a great thermal barrier between the building interior and the exterior, thus minimizing the amount of energy needed for heating the building interior in winter and for cooling it in summer.
The special construction of clay and cement tiles as well as the specialized installation techniques make sure that tile roofs are efficiently ventilated, too, which prevents the roof from heating excessively in harsh sunshine and from transferring any excessive heat towards the building interior.
When you think of a metal sheet that is exposed to harsh sunshine, you probably come to the conclusion that metal is a material with excellent conductive abilities, therefore not great for roofs. While the metal sheets used for making your car’s hood certainly heat up in the sun, the sheets used for roofs use special alloys and they are also treated with reflective coatings that enhance the material’s energy efficiency, making it one of the best materials in terms of energy preservation.
These roofs are made from polyurethane foam sprayed from cans and they provide not only excellent protection from the elements, including rain and wind, but superior energy-efficiency as well. Sprayed-on roofs need to be covered with a special coating that protects it from the sun’s UV rays and that reflect the sun’s heat as well, so spray roofs are among the coolest roofs available today.
Also called living roofing, these modern roofs are very thick and they are covered in vegetation. The special construction of green roofs prevents any heat exchange between the building interior and the world outside the green roof, making the solution not only attractive, but very economical in terms of energy usage as well.
Ways to Increase the Energy Efficiency of Your Roof, Whatever Material It Is Made from
If you already have a roof on your building, you can improve its energy-efficiency by adding insulation right under it. Roofing insulation comes in many types and forms, some come in the form of blankets that can pe laid on the attic floor, others are sprayed or applied into frames, but they all decrease the amount of energy needed for maintaining the temperatures inside the building at comfortable levels.
The color of your roof is also important – light colored roofs reflect heat, so they are great for hot climate areas, while dark roofs absorb heat, making them suitable for colder regions.
