Which of the following is NOT an advantage of metal roofing?

Metal roofing is recognized for several benefits, making it a popular choice in the construction and roofing industry. One significant advantage is its low maintenance costs. Metal roofs tend to resist the elements and require less frequent repairs compared to other materials, which can be cost-effective over time.

Energy efficiency is another beneficial characteristic of metal roofing. Many metal roofs are designed to reflect sunlight, helping to keep buildings cooler and reducing the need for air conditioning during hotter months. This energy efficiency can lead to substantial savings on energy bills.

Moreover, metal roofing is prized for its fire safety due to its non-combustible nature. Metal does not burn, which enhances the overall safety of the structure it protects, especially in areas prone to wildfires.

In contrast, a short life span is not a feature associated with metal roofing; rather, metal roofs are known for their durability and longevity, often lasting 40 years or more with proper maintenance. Therefore, identifying short life span as an advantage is inaccurate. By focusing on the significant advantages of metal roofing, it is evident why the statement about short life span stands out as the correct answer in this question.
