Roof Coatings Phoenix Benefits of Commercial Cool Roofing Systems
If you live in a desert climate, you know the importance of relying on energy to save you from the heat in the summer. You will also be familiar with the large figures on the energy bills as well. Most city spaces and structures in the desert are surfaces which absorb the heat due to their color and material and create what is called the Urban Heat Island effect. Add that to the lack of vegetation and the heat gain will just multiply. This results in a drain on energy reserves. If you’re in the process of constructing a new building or considering a re-roof for your business you might want to ask yourself the question as to what’s the best cool roofing system you need in order to maximize your energy savings for both your location, and your weather and climate in all seasons of the year. A cool roof system will reflect the UV and infrared back into the atmosphere, causing a negligible heat gain. There are several different approaches to get to this effect, of which we talk about below.
Applying a reflective solar coating to your already existing surface is a cost effective and simple option from Roof Coatings Phoenix, it can also reduce roof surface temperatures as much as 50-70 degrees as can be seen in the photo’s above. You can find the data on many products that do this online through simple searches. Like 90% of the US, if you have a darker colored roof, then the peak heat of the sun is contributing to more than double the energy needed. Try and utilize cool roofing products that have Solar Reflective Index (SRI) values of 100 or greater, this can be achieved by knowing the percentages of reflectivity and emissivity of the top layer of the roofing materials. Reflective surfaces can accumulate dirt though, which reduces the benefits substantially so try and select roofing materials that are resistant to dirt pick up and that are self cleaning when it rains. This will maximize the benefits of your cool roofing system and provide you with most payback with lower utility bills.
Inherently cool roofs
White reflective roofs can reflect as much as 80-90% of the sun’s rays back into the atmosphere with high reflectance, and also prevent radiation gain. Compare it to the 6-26% reflection of the traditional asphalt roof, and the benefit becomes very clear declares Roof Coatings Phoenix.
Many countries have experimented with different strategies to help when it comes to having a “green” commercial roof, and not in the manner of color, either. Insulated layers combined with plants and drainage can work with a wind barrier to create the components of a green roof. The benefits of having such a green commerical roof are manifold – you will improve your air quality, create excellent insulation from the elements, cool your environment and have a thriving and unique ecosystem within your business. Governments across the world are now offering benefits to business owners as well as homeowners who have cool green commercial roofing systems, not only to help save energy costs and demands but to also prevent from further damaging the environment. Roof Coatings Phoenix says even though green roofs are unique they can have higher costs associated with those systems due to structural requirements due to plant growth and the need for watering.
