In the past, metal roofs were very popular and now it seems their time has come again.
Modern metal roofing has become a popular alternative to more standard roofing materials such as shingles. Metal roofs are lightweight, low-maintenance, fireproof, energy efficient, durable, and can be manufactured to give virtually any look conceivable.
Another benefit is a metal roof has a life expectancy of over 30 years, and buildings with metal roofs may receive a discount on the homeowner’s insurance.
Metal roofing does usually cost more to install than shingle roofs, but their increased life span can still make them a good value. In addition, metal roofs can often be applied over several layers of old shingles, so the tear-off expenses might be reduced or eliminated. And many metal roof manufacturers also provide a lifetime warranty.
The two most common metal roofing materials are coated aluminum and steel. Both are durable and lightweight. Sometimes the metal is painted with enamel, but more often the coating used is a fluorocarbon coating commonly known as Kynar. This is a durable coating that stays flexible and is more weather resistant than paint. While factory-applied Kynar or paint helps the appearance and rust-resistance of a metal roof, it also eliminates the ability to solder the metal, so particular attention must be paid to details and walls, vents, and valleys.
For those that enjoy the look of tile or slate, the lighter weight aluminum or steel can resemble the look and also be supported by your roof structure. Aluminum is fast-becoming a top choice because it does not rust, it deafens the sound of rain, and it is easily formed to simulate cedar shakes, tiles, and slate. Simulated cedar shakes are most popular and are difficult to distinguish from real shakes. They are available in many standard colors and in a few energy efficient paint options.
Copper and stainless steel are also metal roofing options, but their cost is often outside of the budget of many homeowners.
If you are looking for a new metal roof or to repair an old tin or copper roof (including built-in cornice gutter linings), contact Commonwealth Roofing and see why we have earned the title “The Roofers”.
