When purchasing commercial roofs, the necessary conditions to consider include the roofs’ durability, cost, and energy efficiency. A commercial roof’s durability is one of its most vital qualities, as most commercial roofs are expected to last for at least two decades.
According to https://allseasonsroofer.com the roof type that may be recommended to you might differ depending on the particular area you live in, its weather conditions, and your specific needs. There are many options available for the choice of a commercial roof, each with its cons and pros. And these varieties make choosing a roof a daunting task.
Below are some commercial roof options, their pros and cons, and the environments they might be best suited for.
DIFFERENT TYPES OF COMMERCIAL ROOFS; THEIR ADVANTAGES AND DISADVANTAGES
Metal roofs are one of the most popular roofing systems due to their durability. They have an average lifespan of 40 to 60 years and some of them are integrated with solar and/or snow removal systems.
As its name implies, metal roofs are made from metallic materials like galvanized steel, aluminum, zinc, copper, etc. And since most of these materials are susceptible to rusting, they are often coated with protective surface layers like zinc or tin. This protective layer also reduces damage from exposure to sunlight and other environmental factors.
- They have an attractive finished look.
- They are durable, as evidenced by their 40 – 60 years lifespan.
- They have strong fire resistance.
- They are stronger than traditional roofing materials.
- They are susceptible to corrosion.
Most metal roofs have prices ranging from $120 to $900 per 100 square feet.
While it might be tempting to go for metal roofs due to their shiny effects, it is advised to work with what works best for you rather than what looks best. Since a metal roof has the advantage of strength, fire resistance, and durability, you might want to go for it if you live in an area where these factors are an essential requirement.
