Metal Roofing has become one of the most popular roof coatings available. A metal roof in today's industry is a roofing system made from metal panels or tiles. It is the most important part of protecting a buildings content. Metal Roofs have many advantages because of their lightweight attractive design and overall cost.
Advantages of Installing a Metal Roof
- A metal roof sheet is extremely light-weight, and easy to handle or install.
- Metal roofs are are ideal for most commercial applications because of their high strength to weight ratio.
- A Metal Roof Increases the thermal efficiency of buildings in high temperature areas with its cool roof paints and high emissivity.
- Metal Roofs are fire and spark resistant.
- Metal Roofing is Hail resistant.
- Metal Roofing is Wind resistant.
- 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 couple degrees, the snow usually just slides off. A huge benefit for homes in cold climates that receive high volumes of snow fall.
- Metal is readily recyclable. Aluminum and Copper 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.
- Durability. The lowest end metal roofing (thin gage with acrylic or polyester paints) commonly called AG (agricultural) or Utility panels will last 15-25 years which is roughly 3 times the lifespan of an average asphalt roof (in snow zones). Most metal roofing products today come with a lifetime replacement warranty. These warranties usually cover materials and labor without being prorated.
- Sheet Metal Roofing 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 sheet 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.
- The coatings and fixings on a meta roof sheet can be designed for different environments including industrial and marine locations.
- Design flexibility
- Large sprung curves.
- Rolled bull-nose shapes.
- Copper and Zinc details have historically been proved to last upwards of 100 years with little or no maintenance.
- A Metal Roof is Energy Efficient.
- Metal Roof 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.
- The average life-span of asphalt shingles today (since 2001) is 6-9 years, while residential and commercial grade metal roofing usually lasts from 50-100+ years, depending on the type.
- Metal Roofing is easy to Install.
- Some Steel and Metal Roof products can be installed over open framing, or on a solid substrate.
- Most metal roofing products require very little or no maintenance.
