Metal roofing has become increasingly popular in the last couple of decades and not just because of the sound it makes when it’s rained on! This is mostly due to the advancement of techniques and products. Most metal roofing is extremely durable, is very sustainable, and is an Energy Star rated product.
Although, not all metal roofing materials have an Energy Star rating, there are many color options that do. Energy Star rated roofing products look at two basic criteria; Solar Reflectivity (SR) and Solar Reflectance Index (SRI) to determine if a product can be Energy Star rated.
Solar reflectivity is the material’s ability to reflect the solar energy from the surface of the material. Solar reflectivity (SR) is shown in a numerical value of 0 to 1.0. An SR value of 1.0 means that 100% of the solar energy is reflected back into the atmosphere. Consequently, a value of 0 means that 100% of the solar energy was absorbed by the material. For a product to have an Energy Star Rating it must have an SR value of .25 initially and after 3 years it must be .15 for a steep pitch roof or .65 and .50 for a low pitch roof or often called a flat roof. As you might expect, the lighter colors have a better SR value than the darker metals.
The Solar Reflectance Index (SRI) is a roof’s ability to reject solar heat. This value is derived from using the materials SR value and its’s emissivity value, the material’s ability to release absorbed heat, in accordance with ASDM 1980 calculations. Simply meaning, it determines how much the heat increases on the surface of a material in direct sunlight. Black has an SRI value of 0 because it has poor emissivity and an SR value of only .05 while white has an SRI of 100 because its SR values are .80 and an emissivity of 90. For an Energy Star Rating, there must be an SRI value of at least 29 for a steep slope roof and 78 for a low slope roof.
Metal Roofing is extremely durable, holding up to harshest of storms and standing seam metal roofing can last 50 to 60 years. Most metal roofing products also qualify for a Class IV or Impact Resistant discounts from your insurance provider. However, be aware that discounts come at a price. Typically, a cosmetic waiver must be signed to obtain the discount. This simply means that if your roof is damaged in a hail storm it will not be covered unless there is penetration.
Metal roofing is nearly the most sustainable roofing materials available. Of course, durability and the long lifespan of the roof are leading factors, but also, metal roofing products are made with up to 98% recycled materials. With many attractive Energy Star rated colors, it is easy to see how a beautiful, long-lasting metal roof is a smart, sustainable choice for most homeowners.
There are several different applications for metal roofing that Waters Custom Roofing offer. Such as, standing seam, impressed metals, stone-coated steel roofing, and many more! With so many options how do you determine what’s best for you?
Standing seam metal roofing is probably the most beautiful of all metal roofs and has a very high-end look. It can be found in three different styles: smooth, ribbed and striated. While ribbed and striated options both add beautiful details, they both actually help to keep the panels from warping in the heat, also called oil canning. Oil canning happens when the metal panels heat up and begin to distort. Distortion is normal and temporary, but some homeowners find it to be unsightly. However, with ribbed and striated variations the oil canning is minimized.
Impressed metal roofing materials are designed to look like other roofing materials but with the strength of steel. You can find impressed metal in a slate, tile, and even wood shake look. Impressed metal roofing allows the same great styles of the other roofing materials but with the durability and longevity that metal provides.
Stone coated steel roofing is an impressed metal roofing material with an added stone coating to increase the durability. The added stone coating protects the materials from damages that might occur from debris on the roof to foot traffic during maintenance and inspections.
A copper roof is without a doubt one of the most beautiful roofing materials available in our opinion and, of course, one of the most expensive. It has all the benefits of steel roofing with the beauty of copper. It is durable, long-lasting and virtually maintenance-free. Copper naturally patinas over time which is both a pro and a con. Copper roofs are sometimes referred to as a “living roof”, meaning that the color will continually evolve. However, some people do not like how a copper roof’s color will change over time.
R-panel roofing is the basic corrugated metal roofing that you commonly see with barn roofs. It is an exposed fastener style of roof, which means it’s not the most reliable version of metal roofing. While the panel its self is very durable, the screws that hold it on are not. These screws are fitted with a rubber washer designed to seal the penetration when screwed down tightly. However, these rubber washers will degrade over time and will need to be replaced every 15-20 years, if they were properly installed.
We offer a wide range of different colors you can choose from for your metal roof. It’s important to remember, not all colors are Energy Star rated and whatever color you go with will be on your roof for the (hopefully) the next 15 to 20 years.
We strive to use the best quality products, materials, and installation techniques to provide you with 100% satisfaction. You’ll love your metal roof. If you have any questions, reach out to us and if you want to learn more about metal roofing, check out MRA.
