Metal Roofing

Metal Roofing Has History

Metal roofing sheets 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. 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 altitude or mountain regions. In lower altitudes, this is often mistaken as an advantage to metal roofs as sliding snow can and will cause damage to metal roofs by pulling screws out of the roof creating several holes in the roof. The sliding snow can also pull down rain gutters.

The Old Metal Roof Still Has Value

Metal is readily recyclable. Copper and aluminum roofing products are available with over 95% recycled content. Most metals can be recycled over and over without losing any valuable properties. Recycling is very efficient. As an example: recycled aluminum only requires 5% of the energy to produce as does new aluminum.Metal refining and production and transport of metal roof components can be energy-intensive and is almost always a non-local activity. On the other hand, metal roofing products can often be recycled, and the process is relatively clean and energy efficient. Even 200-year-old Copper, for example, can be easily and inexpensively recycled. Some of the metals that are used today, such as Aluminum and Copper, routinely contain over 80% recycled content. While metal roofs are expensive, rising oil prices have made metal roofs more affordable in relation to asphalt shingles (oil is a principle ingredient in asphalt shingles). At around one dollar per square foot for colored metal sheets in 29 gauge thickness (as of March 2011), brought metal roof prices close, or equal to asphalt shingles.

Metal Roofing Advantages:

  • Light Weight
  • Portability
  • Durability
  • Fire and spark resistant
  • Hail resistant
  • Wind resistant
  • Snow-shedding
  • Recyclable

Modern Metal roofing Requires Professional Installation

Care must be taken on large roofs to provide for thermal expansion and movement. The movement caused by differences in temperature may cause objectionable noises in some roofs; for example, curved roof surfaces. However, this is not a common occurrence. Care must be taken with all metal roof products to avoid the use of incompatible materials. Dissimilar metals can cause unexpected and rapid corrosion. Metal refining and production and transport of metal roof components can be energy-intensive and is almost always a non-local activity.
