If you are in the market for a cool roof to save you money in energy bills and to do your part in helping the environment, there are many options out there for you. Here are just a few products that are likely to grant you the best energy savings possible, while offering the greatest protection for your home or building.
If you own a flat roof, you are provided with convenient energy saving resources. Flat roofing membranes, unlike tar and gravel roofs, are reflective and are designed to save you energy and money. A flat roof membrane's high reflectivity will help to reduce the amount of energy required to cool a building and keep it cool throughout the hottest points of the year. This decreased amount of energy consumption causes a lower amount of pollution to be generated back into the atmosphere and directly contributes to a cooler and cleaner environment, all while you save a little money. Some roofing membranes that are energy efficient include:
TPO is an extremely relfective roofing membrane. Versico's TPO membranes carry the Energy Star rating, and succeeded in exceeding the guidelines to meet that rating. TPO is solar reflective and has a thermal emmitance level of.8 to.9, depending on the color. Versico's TPO is also listed as a CRRC (Cool Roof Rating Council) certified product. This TPO is also 100% recyclable, as well as made from safe materials that do not harm the environment. If you are looking for a roof that will naturally cut down your energy bill, and also succeed in helping the environment, TPO is for you.
EPDM is a truly sustainable product. It is diverse enough to fit the needs of virtually all of the different climates and building structures. For example, if a membrane is not thick enough in a cold climate zone, it will almost immediately result in higher energy output and costs for the property owner. However, EPDM is able to work with different climates to create an energy efficient roof for you an any location. Though EPDM lacks the reflectivity of TPO, it makes up for it in thermal performance. In fact, a recent study performed by the Department of Energy and the EPDM Roofing Association showed that ballast and paver systems (such as EPDM roofing) can save as much energy as a reflective or "cool" roofs.
If you are looking for a way to push your roof over the top in energy savings, TOPCOAT is for you. It is a roofing membrane designed to be sprayed over current roofs, whether it is a single-ply membrane or a metal roof. It holds the Energy Star rating for its solar reflectivity. It has the similar effect of TPO: it decreases the overall building temperature through it's solar reflectivity and thermal emmitance. In fact, TOPCOAT can save you up to 50% of your roof's original cost through energy savings. It also protects seams and joints from wide temperature changes that can negatively effect roofing performance.
Even pitched roofs are following the global trend of energy efficient building products. Since most pitched roofs are residential, they have the potential to save your family from spending money on unneccessary energy bills, while still helping your house look good. They also qualify for a tax credit of up to $1500. Two examples of these cool shingles are:
- GAF's Timberline Cool Series
- CertainTeed's Landmark Solaris
GAF Timberline has introduced the Cool Series shingle in hopes of reducing attic temperatures, and thus reducing energy costs and usage. They are designed with a greater reflectance than tradtional shingles that helps to minimize the amount of heat leaking from your roof into your home. This shingle saves it's residents an average of 7-15% of total cooling costs each year. In warmer climates, cooling cost savings may be greater throughout the entire year. These shingles are based off of the design of the #1 archetectural shingle in America, giving your home the beautiful look you want.
Certainteed Roofing has also come out with a 'cool' shingle: Landmark Solaris. This shingle contains advanced color granules that reflect the sun. This succeeds in reducing the overall roof temperature by up to 20% in the summer, saving you money and energy. Landmark Solaris is rated by the Cool Roof Rating Council, qualifies for credits and points in LEED, NAHB, and other green programs, and meets the ENERGY STAR standards for solar reflectance and thermal emission. However, perhaps the best feature of this shingle is it's beauty. It doesn't look like a cool shingle, but rather it is a beautiful architectural shingle that would look great on any home.
While these products are just a sample of the green products across America, they have been proven to be among the best and most popular choices. Take into consideration the look of the material, as well as the ability to protect your roof in your climate before choosing a product.
