Metal Roofing Advantages Part 2

Welcome back to our blog. Today we have more advantages for installing a metal roof. Besides the durability and affordable cost in the long run, other advantages can be listed:

  • Wind uplift, Hail, and Fire resistant
  • Light Weight
  • Snow shedding: Painted metal roofs are usually snow-shedding. Snow can usually collect when it is fresh and lighter weight. As soon as the ambient temperature rises a few degrees, the snow usually just slides off. For this reason metal roofing is ideal for homes in high latitude or mountain regions.
  • Most metals can be recycled over and over without losing any valuable properties. Recycling is very efficient.
  • Design Friendly: Some steel roofing products can be installed over open framing, or on a solid substrate, straight or curved panels are available.
  • Factory made or on site roll formed.
  • Energy efficiency. Coatings with high reflectivity like Kynar with "cool roof" pigments commonly save 20-30% on air-conditioning costs due to reflecting away much of the sun's heat. Increases the thermal efficiency of buildings in high temperature areas with its cool-roof paints and high emissivity.
  • Most metal roofing products require very little or no maintenance.
  • Metal roof sheets can be used equally well in cladding the sides of a buildings.
it is recommended to use only UL Certified Metal Roof Panels and components, this will give you the peace of mind that what you are getting will be of the best quality.

Metal Roofing Advantages. Part 1

metal roof, often referred to as a tin roof, is a roofing system made from metal pieces or tiles.
Metal roof sheeting in the form of corrugated galvanized steel was a great aid to opening up America in its early days. This is still happening today in parts of the developing world. Now days we can find different alloys, profiles and colors to fulfill the demanding imagination of the architectural and engineering firms.
We can find some advantages and disadvantages as well in a Metal roof, one of the most important advantages is the Durability. The lowest end metal roofing (thin gauge with acrylic or polyester paints) commonly called AG (agricultural) or Utility panels will last 20 to 30 years, which is roughly twice the lifespan of an average asphalt roof. Most metal roofing products today come with warranties from 25 to 50 years. Sheet materials like stainless steel, copper, zinc and aluminum are inherently durable; the oxidization of the base material forms a protective patina. Some modern steel roof sheeting materials are coated with an alloy of zinc and aluminum to give it some of the durability of each of those materials at a lower cost and higher strength than either. Copper and Zinc details have historically been proved to last upwards of 100 years with little or no maintenance. The average life-span of asphalt shingles today (since 2001) is 6 to 9 years, while residential and commercial grade metal roofing usually lasts from 50-100+ years, depending on the type. The coatings and fixings on steel roof sheeting can be designed for different environments including industrial and marine locations.
In the upcoming posts we'll talk about more of these advantages that Metal Roofing has over other types of roofs and the way the Metal Roofing Industry helps the environment and final users by saving energy and resources in many different ways.
