Most people, who are put in the situation of building a new roof, consider the classic solutions in the first place, but metal roofing is becoming an increasingly serious competitor for the asphalt roofs or the traditional solutions (clay tiles, wood shingles…). There are several types of metal roofs, from steel metal tiles to metal roofs based on non-ferrous metals (Aluminum, Copper, Titanium-Zinc). The different materials used in the construction of metal roofs provide distinctive qualities.

Advantages of metal roofing

  1. Metal roofs are easier to install, especially those manufactured into panels that join together, like a puzzle.
  2. Metal roofs are resistant to fire, insects, mold and rot. They are particularly durable when installed by professionals. Most roofing companies guarantee a metal roof installation for up to 30 years or more, the return on investment being significant compared to some traditional solutions.
  3. Metal is a lightweight material, which makes the roofing system safer for the resistance structure of the building. Most metal roofing materials come in panels that can be installed in no time. If the roof is not yet installed and a storm is on the way, shortening the installation time by a day or two can turn to be an essential advantage.
  4. Another reason why metal roofs are so popular nowadays is related to fire resistance. These roofs tend to be non-combustible, so they are often rated class A when it comes to fire resistance. This is the highest score a roof can achieve.
  5. Rapid rainwater drainage. Metal roofs are practically impermeable due to the way the panels are interspersed, but also because the surfaces are hard and slippery.

Boca Raton roofing company metal installation pros tell us that one of the most significant advantages of this type of roofing material refers to energy efficiency, especially in hot climates. This is because the reflection of radiant heat from the sun and thermal inertia are basic features of a metal roof, as well as another reason for the popularity of this type of roofing. The natural reflectivity of the metal reduces heat accumulation and, implicitly, cooling costs. Also, when using a coating (UV-resistant paint, white or light colored, applied to galvanized steel sheet), it also has the role of reflecting solar energy without it being transferred inside the building.

Reducing energy consumption is also beneficial for the environment, not just for the owners’ budget. With a metal roof, electricity consumption for using air conditioners in high temperature conditions can be lower by about 25-30%.

On the other hand, we should also highlight a potential downside. Regardless its reflective nature, a metal roof has a low insulation value. However, it can be installed on a rigid foam insulation, which will greatly improve its performance. In addition, many systems use a ventilated air space between the metal panels and the roof itself, to increase energy efficiency.

Warranties vary widely for different types of metal roofs, but most companies offer between 20 and 50 years. As for paint finishes, they usually have a 30-year limited warranty.
