Installing a metal roof will pay for itself in several ways, including negligible maintenance and repair costs. Once in a while, a "re-screw" might be needed, but even that is unusual. This makes choosing a metal roof for your home a no-brainer if you can afford the initial higher cost.
Other advantages include:
Longevity – Some come with a 50-year warranty on materials and labor, making them a "set it and forget it" situation. At the same time, a typical residential asphalt shingle roof has a far shorter warranty – in some cases, just 15 years. You'll have a roof that will far out-perform a shingle roof.
Energy-Efficient – A metal roof can significantly decrease your power bill during a southern summer's long, hot months! This is because they have built-in sun-reflective properties. Electric bills are one of the most significant expenses in maintaining our homes, and you can't discount the savings over time.
Weather Resistant – You'll never have to worry about a leaking roof when you choose metal. Most costly repairs have to do with water getting in where it doesn't belong. This can lead to unseen structural damage to your home, and by the time it's detected, it's a bigger problem than just a leak.
