Different Options for Cool Roofing

Many property owners and managers throughout the entire country are looking to ensure their property is more Eco-friendly and sustainable. Because of this, it is creating a lot of different and new challenges as well as opportunities for construction professionals across the board.

The top available energy-efficient materials are usually chosen based on how many either hot or cool days are expected to impact the building itself. Scientists use the outdoor temperature of 65-degrees as a temperature that would require no heating nor cooling for optimal comfort. Therefore, that is the temperature that is used. The fact is, one of the things that can play an integral component in the comfort of the building and the performance of the systems is the roof. There are three distinct options to choose from for contractors looking to maximize cooling days including insulation levels, reflectivity, and vegetative surfaces.

The property owners that are located in climates that feature more cooling days than heating days will usually opt for a reflective surface over one that absorbs heat. These are usually referred to as cool roofs and they have to either meet or exceed the minimum solar reflectance and thermal emittance rating systems that are set forth by the local, county, and/or state’s respective building codes and the government’s energy laws. These cool roof systems are typically listed by the Cool Roof Rating Council. This is a program that helps to regulate the various methods of testing to ensure the accurate and unbiased evaluation of cool roofs.

As of the current moment, there are products such as JM PVC, JM PVC SD, and other SBS and Bur membranes that are listed in the directory. You can check it out here:

Vegetative Commercial RoofingThis is another option that you could conceivably consider. This is a roof that tends to be able to absorb water. Therefore, it can help to minimize a building’s energy expenditure from the very beginning. When this type of roof is properly installed and when it is working, it can help to provide ample protection to the surface o the roof from potentially harmful UV ray exposure. This can end up drastically increasing the overall lifespan of the roof. Along with this, it can even better deal with the storm water runoff that roofs experience and it might even eliminate it completely. These various elements can help to reduce any thermal heat that is absorbed from the sun’s rays and it can end up reducing urban heating issues by effectively increasing the albedo absorption rate. This is the portion of the solar energy that is reflected without getting absorbed. Find out more here:

It’s important to keep in mind that these roofs are likely to add more weight to the roof. Because of this, you want to ensure that the current structure is capable of withstanding the excess weight prior to even considering it. While it does have higher upfront costs and it does require more maintenance, a lot of roofing professionals and the entire industry have learned to understand the many benefits it offers.

A vegetative roofs’ albedo and performance in reflectivity aren’t negatively impacted by the various other factors that typically negatively impact cool roofs. Along with this, cool roofs don’t offer any benefits that help improve longevity or the management of storm water. Because of this, there seems to be a lot more increasing demand for this roofing option due to its flexibility to be used in varying climates.

Insulation has become a very important component of ensuring a roof is energy efficient. Adding various additional layers of insulation to a roofing system is something that can effectively lower energy loss and thereby reducing energy costs. This is due to the fact that there is less heat that is moving through the system. When the insulation is properly installed, it can even prevent energy transfer from buildings and the various occupants inside of it.

The science is easy to understand: heat travels and it always looks to flow from warm to cold. That is until the temperature difference is no longer applicable. Thus, the more insulation, the less heat will be able to escape during the colder days throughout the year and the less heat will enter the building on the warmer days. Each of these things can improve overall energy efficiency and savings.

Roofing contractors should always be following the best practices within the industry. This includes using the recommended R-value for whatever region they operate according to the Internal Energy Conservation Code (IECC). This code provides as much as two ways to determine a property’s insulation requirements. It does so with regional codes in specific tables or by adhering to the American Society for Heating, Refrigerating, and Air-Conditioning Engineers Inc. Standard 90.1.

The absolute first decision any building owner or manager must make when they are looking to maximize energy savings should start at the very top. You can choose between a reflective or vegetative surface with the ability to add even more insulation to either. Now is the time for every roofing contractor to capitalize on the abundance of interest and the increasing demand for cool roof options by getting even more educated on the various systems and their benefits.
