Metal roofs have become increasingly popular among homeowners, especially now that they are available in a much wider range of styles and finishes than in the past. Not only are they more flexible, attractive and affordable, but they also have energy-efficient properties that make them a great choice for hot climates. The surface temperature of a metal roof can be very high in hot climates, but not as high as shingles. While unpainted metal can reach 145 degrees in summer, black asphalt shingles can reach 168 degrees.
Metal roofs coated with thermoreflective paint can feel up to 42% colder than unpainted metal roofs. In addition to being able to withstand higher temperatures, metal roofs present a large number of advantages for their owners. They are naturally resistant to termites and pests, and because metal roofs reflect water, roof leaks are rare. The layer of reflective paint that is applied will also prevent rust.
Reapplying it every few years is pretty much the only maintenance a metal roof will require to maintain a like-new appearance. Metal roofs are available in a variety of colors and modern styles that reproduce any type of roof, such as clay shingles, slate and shingles, to name a few. Homeowners have the flexibility to create the curb appeal they want. A metal roof acts as an insulator and naturally reflects the sun's UV radiation, keeping your home cooler in summer and warmer in winter.
You can increase its reflective properties by painting a metal cover in a light color, such as white. On the other hand, asphalt shingles and many other roofing materials absorb energy from the sun, making your home warmer and increasing your energy bills. Depending on the material, traditional roofs usually have a lifespan of 15 to 30 years. However, a metal roof can last 40 to 50 years or more before needing to be replaced. If you combine a metal roof with a few insulating layers, you get a very well sealed and cool house. Not only do metal roofs keep your home warm during the winter, but they also keep you cool during hot summers.
If your metal roof is located directly above an uncontrolled temperature room, such as an attic, insulation and ventilation will be a very important step in ensuring that heat does not build up in an enclosed space. Most metal roofs are treated with Energy Star finishes, which, when combined with paler colors, can cause surface temperatures to be up to 50 degrees lower than shingles. Lower cooling costs are just one of the benefits of choosing to invest in a quality metal roof over shingles and other older materials. Another benefit of proper insulation is that it will prevent the metal roof from becoming too loud during heavy rain, hail, or other inclement weather. Therefore, strong winds generally cannot easily tear off a metal roof, no matter how light it seems. Another advantage of having a metal roof is that it has a low weight compared to other materials. When considering the different advantages that can be obtained from metal roofs, it may seem like a definite choice when it comes to choosing the best type of roof for warm climates.
Whether you're building a new home or replacing your current roof, be sure to consider metal roofs as an option.
