Metal roofs have been used in the industrial and agricultural sectors for years. They are traditionally used to roof warehouses, factories, barns, and sheds. However, it is becoming increasingly common for residential homeowners to replace their home’s roof with a metal roof instead of roof shingles.
In 2013, the Metal Roofing Alliance noted that they are “seeing a steady increase in the demand for metal roofing products and expect to see continued growth.”
The question that needs to be asked and answered is: Why are homeowners moving towards installing metal roofs on their homes instead of installing shingled roofs?
By way of answering this question, let’s look at the top three reasons why metal roofs are becoming increasingly popular with residential homeowners:
Quality metal roofs installed with metal roof accessories in Miami last much longer than a shingled roof. Roughly speaking, a shingled roof needs to be replaced every seven to ten years. On the other hand, a metal roof will last for decades. This fact is backed by the fact that roofing companies offer up to fifty-year warranties on their metal roof installations.
A correctly installed metal roof is stronger than a roof installed with traditional asphalt shingles. Essentially, asphalt shingles are liable to break sooner than metal roof sheets when a heavy object drops on the roof. Shingles also get blown off the roof quicker than metal sheeting, especially during the current cycle of severe weather events. Also, when one or more shingles shifts or breaks, it allows water to leak into the building. Essentially, one metal roof sheet is much longer (and wider) than one asphalt shingle. Thus, the roof sheet is much stronger than the traditional shingle.
Return on Investment
In business, an important metric when measuring the success of an organisation is the Return on Investment (ROI). Simply stated, the ROI is calculated by subtracting the gain (or benefit) from the investment from the cost of the investment. This result is then divided by the cost of the investment. For example, if a metal roof costs $1000 today and in 50 years it costs $50 000, then the ROI on your metal roof is circa $49 000.
The metal roof ROI can then be compared to ROI on a shingled roof to determine whether the ROI on a metal roof or a shingled roof is higher.
Let’s assume for simplicity’s sake, that an equivalent shingled roof costs $500 to replace and needs to be replaced every ten years. Let’s also assume that the cost of the shingle roofing increases by about 10% every ten years. Therefore, the cost of replacing the shingled roof over the same 50-year period is circa $5000. And the ROI is $10.
Therefore, this simple (and broad) calculation shows that it is far better to install a metal roof over a shingled roof, even if the initial cost of the metal roof is twice as high as the cost of the shingled roof.
