Metal roofing materials have long been seen to be the province of stark industrial buildings looking to improve their fire ratings and energy efficiency. But the fact is, energy-efficiency is not the dull, book-balancing issue it once was. With 'green' policies becoming increasingly popular amidst growing concern about global warming and the environment, the energy-saving characteristics of having a metal roof are starting to look more and more desirable for the average person.

On the environmental, carbon-footprint front, metal roofing materials are the preferred roofing constituents for two reasons. Metal reflects light and heat, unlike heat-absorptive materials like asphalt and fiberglass. They consequently lower the amount of air conditioning a home will need to use to stay cool in summer. Add this to the fact that most insurance companies will give you anything up to twenty-five percent off on a policy for a home with a metal roof, and the long-term payoffs are considerable.

Furthermore, residential roofing materials have come a long way in the past few decades, and now come in a wide enough array of design aesthetics to appease even the most architecturally traditional home-owner. Various cunning products are painted and treated to emulate the appearance of wooden slats and even clay-roofing tiles, so that you needn't compromise the classic appearance of your home.

But if you're keen to go for what has become to be the modern era definition of architectural definition of beauty, then you'll be well pleased at the range of metal roofing panels, which can be found in shiny aluminum, the ever-robust stainless steel, and even copper, well known for the way it weathers to a beautiful and quaint-looking green patina.

When Galvalume is used in the crafting of standing-seam metal roof panels, that's when you wind up with the toughest, most durable design imaginable - highly reflective and corrosion-resistant. Standing-seam roof panels have enough flexibility to endure any stresses place on them by wind, ice or strong wind, and they clip together to be just about water tight, meaning there's very little by way of elemental extremes that will challenge the strength of your roof.

So what, exactly, is a standing-seam metal roof's lifespan? Well, scientists have artificially aged metal panels by subjecting them to extreme levels of corrosive gas and heat, and found that, odds are, your average metal roofing materials will last up to seventy years without any need of repair. Of course, you'll have a hard time convincing most manufacturers of that number - their warranties stretch to a 'mere' forty years.
