Metal roofing entails the installation of a roofing system made from metal pieces or tiles. The popularity of metal roofs is on the rise because the roofs are more durable than other roofing materials and homes with metal roofs have higher resale values. A metal roof offers many advantages to the home-owner, including energy savings, expanded color options, longevity and long-term warranties (up to 50 years). According to the U.S. Metal Roofing Alliance, metal roofing can save up to 40 per cent on annual energy costs depending on the geographical region.
Another major advantage of metal roofing is that metal roofs can increase the thermal efficiency of homes in high temperature regions with their cool-roof paints and high emissivity. In addition to that, metal roofs are impervious to rot and mildew and they cannot be damaged by termites – hence their longevity. Metal roofs are also known for their ability to withstand extreme weather conditions including high winds, wildfires and hailstorms. This is the main reasons as to why insurance companies offer discounts of up to 30 per cent to homes with metal roofs.
Metal roofing materials consist of steel, aluminium, copper or tin. Steel is the most common material and may be coated with zinc to reduce maintenance costs and rust. Aluminium is ideal for coastal regions because of its anti-corrosive properties, though it tends to be more expensive compared to steel. Copper is popular for its rich coloring but it is usually the most expensive of all metal roofing materials. Tin is not so popular for homes but it is commonly used on barns and sheds. Metal roofing materials can be recycled and are more environmentally friendly than other materials.
Metal roof shingles are interlocking metal components with less than 3 sq. feet of installed exposure. Roofs made of interlocking metal shingles have been reported to have stayed maintenance-free and watertight for more than 100 years since their installation. This is possible because the interlocking metal roof shingles actually interlock with one another and each of their accessory components, and are secured with heavy-duty stainless steel clips.
Metal roofing price is generally higher than other materials. However, metal roofs last several decades longer than most other roof options – meaning they are cheaper in the long-term. That said, metal roofing price vary depending on your geographical location and other factors such as the materials used to make the metal roof.
When budgeting for roofing costs, always remember to include the cost of removal of old roof, disposal of old materials and installation of the new metal roof. It is also advisable to ask qualified contractors for metal roofing price estimates.
