Plano Roofing: Article About Metal Roofs
Plano roofing professionals encourage homeowners who are looking to install a metal roof to carefully weigh the pros and cons of metal versus traditional roofing materials like asphalt, wood and tile. Steel, aluminum and other forms of metal roofing have benefits and drawbacks of their own.
Metal roofing excels over other roofing materials when it comes to life expectancy. If a metal roof is properly installed, it should last as long as the house does. It will effectively keep out water, it can withstand even the highest winds and it will shed precipitation and snow. Metal roofs are not affected by fire, mildew, wildlife or rot. Warranties vary from company to company, but on average metal roofs are guaranteed for 20 to 50 years. Their painted finishes normally have a 30 year warranty.
Contrary to what some may believe, metal is a relatively lightweight material weighing between 50 to 150 pounds per square. Comparatively, tile weighs in at 750 pounds per square, and concrete weighs in at 900 pounds per square. This means that some styles of metal roofing materials can be placed over an existing roof without having to do a tear off or build extra supports.
One drawback of metal roofs is that they cost a lot more than their traditional counterparts.

This expense is seen upfront during the installation process. However, because of the material's long term durability, if a person stays in the home for many years, they will ultimately save the difference and then some.
For some homeowners, the sound of rain hitting a metal roof is like living inside a drum. During a rainstorm or during a hailstorm, living under a metal roof is going to be a lot noisier than living under thick slate or tile. Structural barriers, sound deadening insulation and plywood sheathing can help block the noise.
Denting is another drawback with a metal roof. In the same way that an automobile will be dented if it is hit by a golf ball, large hail stones can dent metal roofs. However, some styles of metal roofs are guaranteed not to dent.
Metal expands and contracts with changes in the temperature. Most new metal roofing systems come equipped with fastenings that are made to move with the roof. However, instances where this is not the case will cause fasteners that are secured to the roof to eventually loosen as the roof expands and contracts.
Metal roofs are durable, fireproof and are able to withstand all types of weather. When properly maintained, a homeowner should reasonably expect that their metal roof will be around as long as their home is standing.
