Advantages of a Metal Roof
-Light Weight -Portability -Durability. The average life-span of asphalt shingles today (since 2001) is 20 years, while residential and commercial grade metal roofing usually lasts from 50-100+ years, depending on the type. -Metal roofs are often used to cover large buildings because of their high strength to weight ratio. The roof of the new Wembley Stadium is an example. It consists of approximately 40,000 sq ft (3,700 m2) steel sheeting. -Fire and spark resistant. -Hail resistant. -Wind resistant. -Snow shedding: Painted metal roofs are usually snow-shedding. -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. -Design flexibility: Some Steel roofing products can be installed over open framing, or on a solid substrate. -Large sprung curves. -Rolled bull-nose shapes. -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. -Labour efficient -Most metal roofing products require very little or no maintenance. |
Rust
Today's metal roofing systems are built to last. Steel metal roofing has a "metallic coating" made of either zinc or a combination of zinc and aluminum. This metallic coating prevents rust from forming and is bonded to the steel at the factory. Paint is then applied over the metallic coating to provide the long-lasting color homeowners desire. 
Long Lasting
The average life of a non-metal roof is 17 years. Asphalt can require re-roofing every 10 to 20 years, often sooner. But a metal roofing system offers unmatched durability, lasting 2 to 3 times longer. Chances are good that a metal roof will be the last roof you ever install on your home. 
Noise
A common misconception is that a metal roof will be noisier than other types of roofing. When installed with solid sheathing, a metal roof on your home will actually silence noise from rain, hail and bad weather,many times much better than other roofing materials. |
