The Benefits and Drawbacks of Metal Roofs

temp-post-image






If you're in need of roof replacement in Dallas, deciding what type of roof material makes sense for your home or property can be overwhelming at best. There are number of terrific choices such as wood, slate, metal, asphalt, even clay and concrete tile. For instance, one of the most popular non-asphalt roof types is metal roofing. But how do you know if metal roofing is right for you and your home? Today we’ll discuss the benefits and drawbacks of metal roofing to help you make the most informed decision possible!






What are the Benefits of Metal Roofing?



Life Expectancy. Properly installed by a Dallas roofing expert, a metal roof should last as long as the home or property, sealing out water, outlasting high winds, and casting off snow quickly and easily. Metal is fire resistant, as well as resistant to mildew, and bugs. Most Dallas roofing contractors back their products with a 20 to 50 year warranty while paint finishes commonly have a 30-year limited warranty.



Weight. Compared to many other Dallas roofing materials, including tile, metal roofing is quite lightweight. Most varieties run from 50 to 150 pounds per square. Because of metal roofing’s light weight, you can often save on engineering and building the supporting structure. In some instances, some types of metal roofing can be applied on top of existing roof structures without the need for tear-off.



Installation Speed and Ease. Many metal roofing materials come in panels spanning 12- to 36-inches in width. An experienced, competent, Dallas roofing contractor can install a metal roof system quickly and effectively. This can be especially handy if your roof has been damaged or torn-off and a storm is on the way. Through ease of installation, shortening the process by a day or two is not out of the realm of possibility. As a result, there can also be a significant reduction in labor costs.



Fire Resistance. As metal roofing systems are noncombustible, they commonly carry a Class A fire rating (the most fire-resistant rating available). However, if your metal roof is installed over an existing roofing system, that can lower the class rating depending on the material it is being installed over.



Heat Conduction. Metal can be effective at reflecting heat radiating from the sun, dramatically reducing midday heat gain. This translates into a significant reduction in energy costs related to cooling your home. Though the metal material itself is low in R-value (insulation capability), metal roofing can be applied over rigid-foam insulation that has higher R-values. Additionally, many metal roofing systems employ a dead-air space between the metal and roof deck to improve overall energy efficiency of the system.



Maximum Shedding of rain and Snow. If you live in a climate that experiences consistently heavy snowfalls or rainy weather, metal roofing can be advantageous because it is virtually impervious to rain and snow. And because the surfaces are hard and slick, it effectively sheds snow and rain. Since most metal roofing systems are darker in color, it conducts heat more quickly, helping to further melt snowfall.



What are the Drawbacks of Metal Roofing





Though there are several benefits to metal roofing, it’s also important to understand some the drawbacks in order to make a fully informed decision about whether metal roofing is right for you an your property:



Cost. Perhaps the largest ‘con’ is the initial cost. You can expect to pay roughly from $150 to $600 per square. Due to metal roofing’s long-term durability, the idea is that you save the difference (and in fact more) if you stay in the house for a lengthy period of time. You also save on seasonal maintenance. If you plan to move in a few years, you’re far less likely to reap the return on investment a metal roof affords.



Noise. In a rainstorm or hailstorm, living underneath some thin sheets of metal is absolutely going to be noisier than living beneath asphalt, tile, or slate. Some find it romantic and homey. Others find it drives them crazy. There is good news - noise can be controlled both by using materials that have structural barriers to minimize the drumming effect and by applying them over solid plywood decking.



Denting. This is perhaps one of the most significant drawbacks to choosing a metal roof. Just as your car dents if a golf ball hits it, a metal roof can sustain similar dents in a hail storm. Copper and aluminum roofing, much softer than steel, are more prone to denting. There are types of metal roofs that are guaranteed not to dent.



Expansion & Contraction. Because metal expands and contracts as it warms and cools, most new products have fastening systems that accommodate movement. Otherwise, fasteners that secure the roofing may tend to come loose. Expansion and contraction on hot days can cause a wavy affect.



Modifications. Metal roofing materials installed in large panels are more difficult to replace if damaged than individual shingles. Also, if you remodel or add on to your home 10 or 20 years from now, it may be difficult to match the material.



Lightning. Many people assume that because metal conducts electricity, it also attracts it. This really isn’t the case, and many instances have been documented where lightning has struck trees or other high objects located near metal roofs rather than the roofs themselves. Just the same, metal roofs can be easily grounded by a lightning protection company.
