What Are The Benefits of A Metal Roof

The National Roofing Contractors Association (NRCA) claims that the popularity of metal roofing has grown remarkably over the past decade, which is a clear indication that both homeowners and flood restoration melbourne builders are becoming more and more aware of the numerous benefits of this roofing material. Before choosing to put a new roof or replace the existing one with a metal roof, there are several factors that can help you identify the right product for your residential or commercial building.

Classifications of metal roofing

There are two main classifications: architectural style and structural style. Architectural style metal panel systems (hydrokinetic) provide a similar function to asphalt shingles in that they are water shedding. These roofing systems do not add to the structural integrity of the building. As such, they are used for moderate-to-steep applications, and usually have a solid substrate, like a wood deck, to give the roofing system adequate stability. Additionally, a waterproofing underlayment is installed beneath the panels to keep water from infiltrating into the building. They can be made from aluminum, zinc, stainless or galvanized steel.

Structural metal panel systems (hydrostatic), on the other hand, add structural stability to your building. They serve as both the roof deck and waterproofing structure, and do not require any underlying support. They can be used for roofing in moderate-to-low sloping structures owing to their water-tight attribute.

Advantages of using metal roofs

Longevity – this roofing material is very durable, with manufacturer warranties on defects ranging from 20 to 50 years, and 20 to 25 years on the coating finish.

Fire-resistant qualities – since metal is non-combustible, most roofing applications are awarded Class A fire rating. However, the rating may be lowered of the metal panel system is installed over combustible substrate, like existing timber.
