Metal is one of the few materials that can be used for both steep slope roofs and low slope roofs. Low-slope roofs can be covered with steel, aluminum, zinc, or copper just like steep roofs. While metal can be an expensive option in the short term, superior durability and simple maintenance of metal roofs typically saves money in the long term. Metal roofs are also one of the most environmentally sound roofing options, with most metal roofing material already containing 30-60% recycled content, and the product itself being 100% recyclable.
Metal roofing is a broad term and can refer to many different roofing systems:
Standing seam panels have a vertical seam. Each panel is fastened to the substrate with the next panel lapping over the fasteners of the preceding panel and locking in place with either a tension lock (snap-lock) or a mechanically-seamed lock.
If the roofline of your home is steep or flat, you may want to opt for a metal roof. Made with either constructed or solid metal, this type of roof is both durable and enduring.
Advantages of metal include easy installation and it’s ultra-lightweight, about half the weight of asphalt (100 lbs per 100²ft versus 240 lbs per 100²ft). And, of course, metal roofing doesn’t burn.
Corrugated panels are usually galvanized sheet metal in multiple colours extruded into various corrugated configurations corrugated panels are fastened with an exposed self-sealing screw or nail. This system is generally used on barns or out-buildings. The benefit of this system is that it has the lowest initial financial output. The downside is that there are still maintenance issues with this system – mainly the exposed fasteners need to be replaced approximately every 10 years. Another consideration with corrugated panels is that they are manufactured in a warehouse off site so there are limitations on length due to shipping requirements. If you require long panels, laps in the metal panels may need to be incorporated into your roof.
