Metal roofing is gaining popularity more and more each day because more homeowners nowadays are opting for a sustainable and energy efficient construction. Metal roofing adapted to the needs that rose during the 21st century. This enabled the roofing technology to birth a more durable and efficient alternative to the otherwise traditional and continuously-replenishing roofing materials. Below are reasons why metal roofing is becoming more popular.
Metal Roofing Basics
Metal roofing is considered as the superior choice as compared to other traditional roofing materials. Metal roofing suppliers enabled the construction of roofing materials that would fare well with solar energy, green construction, and 21st century technology. They also have several roofing benefits that would assure homeowners that they made the right choice.
Metal Roofing Benefits
Metal roofing are considered to have a durable design – proven to last for half a century or even more. They are also known for their low maintenance roofing due to the fact that they need no regular repairs or replacement. Metal roofing also offers extra insulation for those cold months and they have superior energy efficiency. They are known to offer protection during the harsh weather with high winds. Because they are less likely to get damaged they offer long term warranty which in turn would promote cost savings through energy efficiency and reduced labour costs. Aside from that, they also promote quick and efficient construction. Metal roofing is an option that will withstand climate change. They are both a safe fireproof roofing option with superior cooling and insulation and they have easy to install solar panels. You can definitely save a lot on demolition if you decide on installing metal roofing over an old roof. You don’t have to worry about termites or moisture and you will definitely be protected from wildfires and extreme weather conditions.
Metal Roofing as the Modern Roofing Solution
Metal roofing will not only last for a long time, it will also protect you and your family against harsh weather conditions. It is adaptable to almost any type of weather or climate, so metal roofing construction is the future of roofing and home building. Metal roof installation usually takes less time than a traditional roof. Save on time and costs associated with human error. Many times you can install a metal roof over an older roof.

ZINCALUME® steel and galvanised products have very similar working characteristics. Since they are materials that are industrial in nature, it is important to be aware of their few characteristics. Below are some helpful information regarding Zincalume steel.
At the cut edge, ZINCALUME® steel provides similar protection to galvanised coatings. The zinc or aluminium alloy coating of ZINCALUME® steel provides galvanic protection to bare steel exposed at cut edges and by deep scratches.
Surface passivation enhances the protection of the galvanised and ZINCALUME® steel product during storage, forming, handling and fixing. It largely eliminates the need for rollforming oils, offers improved wet stack corrosion resistance and generally makes the product more mark resistant during handling and fixing.
Handling and Storage
The normal storage care, site cleanliness and installation procedures used for GALVSTEEL® products apply to ZINCALUME® steel products. Although passivation provides improved protection during storage, care should still be taken. If ZINCALUME® steel becomes wet during storage, the product should be immediately separated, wiped with a clean cloth and placed in a position where it can completely air dry.
As with GALVSTEEL®, ZINCALUME® steel is suitable for all but the most severe forming operations. With ZINCALUME® steel, the passivation system acts as a dry lubricant and in most cases will eliminate the need for additional lubrication in most forming operations. Solvent-based lubricants must not be used.
ZINCALUME® steel can be satisfactorily welded using the following techniques: GMA (Gas Metal-Arc, often called MIG), Resistance welding (spot or seam) and MMA (Manual Metal-Arc). When welding ZINCALUME® steel, excessive weld currents must be avoided. With correct welding procedures, sufficient coating is normally left on the ZINCALUME® steel sheet to protect the substrate from corrosion. Weld repair should be carried out by coating with a zinc-rich paint. Adequate ventilation must be provided even though the welding of ZINCALUME® steel gives off fewer fumes than galvanised steel.
Joining and Sealing
ZINCALUME® steel cannot be soldered. Join ZINCALUME® steel in the same way as recommended for COLORSTEEL® prepainted steel products. Use a neutral cure silicone sealant in conjunction with mechanical fasteners such as blind rivets. Care should be exercised in the choice of rivets. Aluminium rivets are recommended. Monel, stainless steel and carbon steel rivets must not be used.
Most fasteners complying with the corrosion requirements of Australian Standard AS3566 “Screws – Self-drilling for the building and construction industry” are suitable for use with ZINCALUME® steel. Stainless steel fasteners should not be used with ZINCALUME® steel or COLORSTEEL® prepainted steel products in any environment. Aside from that, lead headed nails must not be used and you should use only low carbon (< 15%) non–conductive sealing washers.
