The price varies widely depending on the metal roofing material you choose, of course. Believe it or not, metal roofs are considered even environmentally friendly. This is because recycled scrap often accounts for more than a quarter of the average metal roof. In addition, because it is possible to install metal roofs over existing shingles, there is often less construction debris being dumped into a landfill.
An excellent option for homeowners thinking about installing a high-quality metal roof is to use steel roofing material. Metal roofing sheets not only look great, but they also offer a lot more benefits for homeowners when it comes to roofing. They last much longer than asphalt shingles, look much more modern and hold up better in extreme weather conditions than alternatives. According to the Palm Beach Post, metal roofs proved to be the most resistant to hurricanes.
Metal roofing products can be manufactured from a variety of metals, including galvanized steel, copper, aluminum, or tin, and can use a number of different installation systems. Asphalt shingles are more common and finding roofing contractors prepared to immediately repair any asphalt shingle roof is quite simple. Shingles are usually nailed to wood-framed roof structures, laid in layers, and staggered upwards from the lowest point of a pitched roof. Most metal roofing systems manufactured today have an interlocking edge system, so it is also recommended to pay attention to detail and review instructions before starting the project.
Unlike an asphalt tile roof, wood tile roof, or most other roofing materials, metal roofing is a material in which fewer roofers are trained and practiced. In fact, federal rebates are offered for metal roofs that have suitable pigmented coatings that meet the EnergyStar requirements. With metal roofing systems, it is generally recommended to have qualified specialists to perform the installation. Fear of lightning strikes may be an imaginary problem, but metal roofs have some genuine disadvantages.
In addition, many systems use a dead air gap between the metal surface and the roof cover below to minimize heat transfer and increase energy efficiency. Asphalt shingles are inexpensive and easy to maintain, but they usually require more maintenance than a metal roof. A properly installed quality metal roof should last 40-50 years, sealing off water, surviving strong winds and shedding snow easily. Homes with metal roofs tend to sell for slightly higher values, probably due to the longevity of the material and its popularity over the past few years.
In ski areas known for heavy snowfall, metal roofs are usually equipped with snow guards, metal or plastic clips, or even horizontal bars mounted on sturdy supports. Metal roofs weigh 1 to 3 pounds per square foot, depending on material thickness and profile. Asphalt shingles generally cost between a third and half of what their metal roofing counterparts cost. This is because metal roofs are very energy efficient; they reflect solar radiant heat, which can reduce energy costs by up to 25%.
