Green Roofing top of page It is no secret that taking steps to become more energy efficient and green in your day-to-day life can go a long way toward saving money in the long run, while making a positive impact on the environment. Energy efficient roofing is a great way to dramatically reduce the amount of energy your household uses, significantly lowering your utility bills. While purchasing an energy efficient roof for your home is an investment, the cost is made up for in just a few years with money saved in reduced utility bills. Zenith Roofing professionals can help you design your roof for energy efficiency by the following methods:
  • Radiant Barrier – When heat from the sun reaches your roof, it is either reflected or emitted. Reflective products reflect the heat away from the house before it enters. A radiant barrier is a method to prevent heat transfer. Heat is always transferred from the hotter area to the cooler area. Ceiling insulation and other products are used in the radiant barrier process.
  • Ventilation – Ventilation is achieved by:
    • Static Vents – Flat vents with no power usually placed near the top of the roof.
    • Ridge Vents – Appear as a raised ridge when viewed from the ground. They allow hotter air to rise out through the highest place on the roof.
    • Wind Turbines – Vents with a top that spins when the wind blows. The fins are designed to suck air out of the attic. This method works great when it’s windy, but not as well on a hot day with little wind.
    • Power Turbines – Vents with a motorized fan. These have a thermostat set at a specific temperature. When the attic reaches that temperature, the fans turn on. This works great on hot days.
    • Soffit Vents – Vents in the soffit are crucial for the ventilation system. For the roof vents to work, the air removed must be replaced. Without soffit vents, the air is replaced by air from other roof vents. Soffit vents allow the hotter air at the top of the attic to be removed while cooler air from lower is pulled in.
    • Gable Vents – These vents are usually louver style in the side of the house near the roof, but not on the roof.
  • Roofing Material Selection and Color – Cool Roofing is a common phrase for products in certain colors to prevent heat buildup. Manufacturers have developed products that even in darker colors are more efficient than previous versions of those colors. When selecting products and colors, ask about the Cool Roofing status of the products.
  • Insulation
    • Attic Above Ceiling – Most houses in Texas have insulation on the ceiling. This is usually a loose layed product that is blown in or a rolled product. Over time, it gets stepped on or moved around. This should be checked for hot spots or missing areas.
    • Under Deck – Many buildings install insulation to the underside of the deck. Depending on the house design, this can make the attic a cooled space.
    • Above Deck – This is common on commercial buildings, but seldom on houses. Nailbase insulation is a product that uses high R-value polyisocyanurate insulation with plywood or OSB to create an insulated roof system.
