When buying a replacement roof, there are a variety of factors homeowners need to consider, including: appearance, energy efficiency, cost, return on investment and most importantly, life expectancy. The roof of your home can make a huge difference between a simple house that provides basic shelter, and a safe and secure home. That is why homeowners should select a replacement roof that will not only offer safety from the elements, but one that is highly durable. Life expectancy is an important factor to consider, so when it comes to a metal roof vs shingle roof, which is best? In terms of life expectancy, metal roofing is far superior to shingle roofing. Often, however, the cost of a metal roof can be off-putting for many homeowners. That is why shingle roofs, which still offer a great life expectancy, are one of the most popular roofing materials across the US.
