St Louis Roofing: Article About Benefits and Drawbacks Of Metal Roofing
Metal roofing comprises about 10 percent of the roofing market. Part of that reason is because homeowners are unaware of the benefits of metal roofing. Many of them believe that it can only be purchased as corrugated metal or with raised ridge lines. While metal can still be purchased both ways, the technological advancements of the last few years mean that metal roofing can be purchased in a variety of styles that mimic other roofing materials, including tile and asphalt shingle. Metal St Louis roofing can even be purchased in a multitude of colors, including blue, red, green and black, which helps homeowners meet HOA requirements or stand out if desired.
Metal roofs have useful lives of between 20 and 50 years depending on the rating of the metal roof and the proficiency of the installers. Many metal roofs come with warranties of up to 30 years, which protects the homeowner against faulty panels and installation.
Roofs made of this material are extremely durable. They can be designed to withstand winds of up to 140 miles per hour, which is better than standard building code requirements. Metal roofs are also able to withstand extreme downpours and hail. When it comes to hail and snow, metal roofs tend to shed their snow and ice, which prevents the roof from becoming overweight.

For homeowners worried about fire, metal roofs do not burn, so there is very little risk of a burning ember landing on the roof and starting a fire.
Metal roofs are environmentally friendly. They reflect the sun's rays, preventing the sun from heating up the attic. Hot attics lead to higher utility bills. Metal roofs are also lightweight when compared to asphalt shingles. Metal roofing weighs between 50 and 150 pounds per square; asphalt shingles can weigh as much as 900 pounds per square. This means that metal roofs are light enough to be installed over asphalt shingles, which reduces landfill waste and costs to install because there are minimal disposal expenses.
With all the positives of metal roofing, it is hard to believe that there are downsides. Unfortunately, metal roofing can be loud during thunderstorms and hail storms. If the hail is exceptionally large, the metal panels can dent. Some low quality metal roofs can start to chip, fade and rust with time. However, regular maintenance can reduce the deterioration. It also costs more to install a metal roof than a traditional shingle roof.
